9 Of all the configuration files needed to run {\bf Bacula}, the Director's is
10 the most complicated, and the one that you will need to modify the most often
11 as you add clients or modify the FileSets.
13 For a general discussion of configuration files and resources including the
14 data types recognized by {\bf Bacula}. Please see the
15 \ilink{Configuration}{ConfigureChapter} chapter of this manual.
17 \section{Director Resource Types}
18 \index[general]{Types!Director Resource}
19 \index[general]{Director Resource Types}
21 Director resource type may be one of the following:
23 Job, JobDefs, Client, Storage, Catalog, Schedule, FileSet, Pool, Director, or
24 Messages. We present them here in the most logical order for defining them:
26 Note, everything revolves around a job and is tied to a job in one
31 \ilink{Director}{DirectorResource4} -- to define the Director's
32 name and its access password used for authenticating the Console program.
33 Only a single Director resource definition may appear in the Director's
34 configuration file. If you have either {\bf /dev/random} or {\bf bc} on your
35 machine, Bacula will generate a random password during the configuration
36 process, otherwise it will be left blank.
38 \ilink{Job}{JobResource} -- to define the backup/restore Jobs
39 and to tie together the Client, FileSet and Schedule resources to be used
40 for each Job. Normally, you will Jobs of different names corresponding
41 to each client (i.e. one Job per client, but a different one with a different name
44 \ilink{JobDefs}{JobDefsResource} -- optional resource for
45 providing defaults for Job resources.
47 \ilink{Schedule}{ScheduleResource} -- to define when a Job is to
48 be automatically run by {\bf Bacula's} internal scheduler. You
49 may have any number of Schedules, but each job will reference only
52 \ilink{FileSet}{FileSetResource} -- to define the set of files
53 to be backed up for each Client. You may have any number of
54 FileSets but each Job will reference only one.
56 \ilink{Client}{ClientResource2} -- to define what Client is to be
57 backed up. You will generally have multiple Client definitions. Each
58 Job will reference only a single client.
60 \ilink{Storage}{StorageResource2} -- to define on what physical
61 device the Volumes should be mounted. You may have one or
62 more Storage definitions.
64 \ilink{Pool}{PoolResource} -- to define the pool of Volumes
65 that can be used for a particular Job. Most people use a
66 single default Pool. However, if you have a large number
67 of clients or volumes, you may want to have multiple Pools.
68 Pools allow you to restrict a Job (or a Client) to use
69 only a particular set of Volumes.
71 \ilink{Catalog}{CatalogResource} -- to define in what database to
72 keep the list of files and the Volume names where they are backed up.
73 Most people only use a single catalog. However, if you want to
74 scale the Director to many clients, multiple catalogs can be helpful.
75 Multiple catalogs require a bit more management because in general
76 you must know what catalog contains what data. Currently, all
77 Pools are defined in each catalog. This restriction will be removed
80 \ilink{Messages}{MessagesChapter} -- to define where error and
81 information messages are to be sent or logged. You may define
82 multiple different message resources and hence direct particular
83 classes of messages to different users or locations (files, ...).
86 \section{The Director Resource}
87 \label{DirectorResource4}
88 \index[general]{Director Resource}
89 \index[general]{Resource!Director}
91 The Director resource defines the attributes of the Directors running on the
92 network. In the current implementation, there is only a single Director
93 resource, but the final design will contain multiple Directors to maintain
94 index and media database redundancy.
100 Start of the Director resource. One and only one director resource must be
103 \item [Name = \lt{}name\gt{}]
105 \index[dir]{Directive!Name}
106 The director name used by the system administrator. This directive is
109 \item [Description = \lt{}text\gt{}]
110 \index[dir]{Description}
111 \index[dir]{Directive!Description}
112 The text field contains a description of the Director that will be displayed
113 in the graphical user interface. This directive is optional.
115 \item [Password = \lt{}UA-password\gt{}]
116 \index[dir]{Password}
117 \index[dir]{Directive!Password}
118 Specifies the password that must be supplied for the default Bacula
119 Console to be authorized. The same password must appear in the {\bf
120 Director} resource of the Console configuration file. For added
121 security, the password is never passed across the network but instead a
122 challenge response hash code created with the password. This directive
123 is required. If you have either {\bf /dev/random} or {\bf bc} on your
124 machine, Bacula will generate a random password during the configuration
125 process, otherwise it will be left blank and you must manually supply
128 The password is plain text. It is not generated through any special
129 process but as noted above, it is better to use random text for
132 \item [Messages = \lt{}Messages-resource-name\gt{}]
133 \index[dir]{Messages}
134 \index[dir]{Directive!Messages}
135 The messages resource specifies where to deliver Director messages that are
136 not associated with a specific Job. Most messages are specific to a job and
137 will be directed to the Messages resource specified by the job. However,
138 there are a few messages that can occur when no job is running. This
139 directive is required.
141 \item [Working Directory = \lt{}Directory\gt{}]
142 \index[dir]{Working Directory}
143 \index[dir]{Directive!Working Directory}
144 This directive is mandatory and specifies a directory in which the Director
145 may put its status files. This directory should be used only by Bacula but
146 may be shared by other Bacula daemons. However, please note, if this
147 directory is shared with other Bacula daemons (the File daemon and Storage
148 daemon), you must ensure that the {\bf Name} given to each daemon is
149 unique so that the temporary filenames used do not collide. By default
150 the Bacula configure process creates unique daemon names by postfixing them
151 with -dir, -fd, and -sd. Standard shell expansion of the {\bf
152 Directory} is done when the configuration file is read so that values such
153 as {\bf \$HOME} will be properly expanded. This directive is required.
154 The working directory specified must already exist and be
155 readable and writable by the Bacula daemon referencing it.
157 If you have specified a Director user and/or a Director group on your
158 ./configure line with {\bf {-}{-}with-dir-user} and/or
159 {\bf {-}{-}with-dir-group} the Working Directory owner and group will
160 be set to those values.
162 \item [Pid Directory = \lt{}Directory\gt{}]
163 \index[dir]{Pid Directory}
164 \index[dir]{Directive!Pid Directory}
165 This directive is mandatory and specifies a directory in which the Director
166 may put its process Id file. The process Id file is used to shutdown
167 Bacula and to prevent multiple copies of Bacula from running simultaneously.
168 Standard shell expansion of the {\bf Directory} is done when the
169 configuration file is read so that values such as {\bf \$HOME} will be
172 The PID directory specified must already exist and be
173 readable and writable by the Bacula daemon referencing it
175 Typically on Linux systems, you will set this to: {\bf /var/run}. If you are
176 not installing Bacula in the system directories, you can use the {\bf Working
177 Directory} as defined above. This directive is required.
179 \item [Scripts Directory = \lt{}Directory\gt{}]
180 \index[dir]{Scripts Directory}
181 \index[dir]{Directive!Scripts Directory}
182 This directive is optional and, if defined, specifies a directory in
183 which the Director will look for the Python startup script {\bf
184 DirStartup.py}. This directory may be shared by other Bacula daemons.
185 Standard shell expansion of the directory is done when the configuration
186 file is read so that values such as {\bf \$HOME} will be properly
189 \item [QueryFile = \lt{}Path\gt{}]
190 \index[dir]{QueryFile}
191 \index[dir]{Directive!QueryFile}
192 This directive is mandatory and specifies a directory and file in which
193 the Director can find the canned SQL statements for the {\bf Query}
194 command of the Console. Standard shell expansion of the {\bf Path} is
195 done when the configuration file is read so that values such as {\bf
196 \$HOME} will be properly expanded. This directive is required.
198 \item [Heartbeat Interval = \lt{}time-interval\gt{}]
199 \index[dir]{Heartbeat Interval}
200 \index[dir]{Directive!Heartbeat}
201 This directive is optional and if specified will cause the Director to
202 set a keepalive interval (heartbeat) in seconds on each of the sockets
203 it opens for the Client resource. This value will override any
204 specified at the Director level. It is implemented only on systems
205 (Linux, ...) that provide the {\bf setsockopt} TCP\_KEEPIDLE function.
206 The default value is zero, which means no change is made to the socket.
209 \label{DirMaxConJobs}
210 \item [Maximum Concurrent Jobs = \lt{}number\gt{}]
211 \index[dir]{Maximum Concurrent Jobs}
212 \index[dir]{Directive!Maximum Concurrent Jobs}
213 \index[general]{Simultaneous Jobs}
214 \index[general]{Concurrent Jobs}
215 where \lt{}number\gt{} is the maximum number of total Director Jobs that
216 should run concurrently. The default is set to 1, but you may set it to a
219 The Volume format becomes more complicated with
220 multiple simultaneous jobs, consequently, restores may take longer if
221 Bacula must sort through interleaved volume blocks from multiple simultaneous
222 jobs. This can be avoided by having each simultaneous job write to
223 a different volume or by using data spooling, which will first spool the data
224 to disk simultaneously, then write one spool file at a time to the volume
225 thus avoiding excessive interleaving of the different job blocks.
227 \item [FD Connect Timeout = \lt{}time\gt{}]
228 \index[dir]{FD Connect Timeout}
229 \index[dir]{Directive!FD Connect Timeout}
230 where {\bf time} is the time that the Director should continue
231 attempting to contact the File daemon to start a job, and after which
232 the Director will cancel the job. The default is 30 minutes.
234 \item [SD Connect Timeout = \lt{}time\gt{}]
235 \index[dir]{SD Connect Timeout}
236 \index[dir]{Directive!SD Connect Timeout}
237 where {\bf time} is the time that the Director should continue
238 attempting to contact the Storage daemon to start a job, and after which
239 the Director will cancel the job. The default is 30 minutes.
241 \item [DirAddresses = \lt{}IP-address-specification\gt{}]
242 \index[dir]{DirAddresses}
244 \index[general]{Address}
245 \index[dir]{Directive!DirAddresses}
246 Specify the ports and addresses on which the Director daemon will listen
247 for Bacula Console connections. Probably the simplest way to explain
248 this is to show an example:
253 ip = { addr = 1.2.3.4; port = 1205;}
255 addr = 1.2.3.4; port = http;}
264 ip = { addr = 1.2.3.4 }
265 ip = { addr = 201:220:222::2 }
267 addr = bluedot.thun.net
273 where ip, ip4, ip6, addr, and port are all keywords. Note, that the address
274 can be specified as either a dotted quadruple, or IPv6 colon notation, or as
275 a symbolic name (only in the ip specification). Also, port can be specified
276 as a number or as the mnemonic value from the /etc/services file. If a port
277 is not specified, the default will be used. If an ip section is specified,
278 the resolution can be made either by IPv4 or IPv6. If ip4 is specified, then
279 only IPv4 resolutions will be permitted, and likewise with ip6.
281 Please note that if you use the DirAddresses directive, you must
282 not use either a DirPort or a DirAddress directive in the same
285 \item [DirPort = \lt{}port-number\gt{}]
287 \index[dir]{Directive!DirPort}
288 Specify the port (a positive integer) on which the Director daemon will
289 listen for Bacula Console connections. This same port number must be
290 specified in the Director resource of the Console configuration file. The
291 default is 9101, so normally this directive need not be specified. This
292 directive should not be used if you specify DirAddresses (N.B plural)
295 \item [DirAddress = \lt{}IP-Address\gt{}]
296 \index[dir]{DirAddress}
297 \index[dir]{Directive!DirAddress}
298 This directive is optional, but if it is specified, it will cause the
299 Director server (for the Console program) to bind to the specified {\bf
300 IP-Address}, which is either a domain name or an IP address specified as a
301 dotted quadruple in string or quoted string format. If this directive is
302 not specified, the Director will bind to any available address (the
303 default). Note, unlike the DirAddresses specification noted above, this
304 directive only permits a single address to be specified. This directive
305 should not be used if you specify a DirAddresses (N.B. plural) directive.
307 \item [DirSourceAddress = \lt{}IP-Address\gt{}]
308 \index[fd]{DirSourceAddress}
309 \index[fd]{Directive!DirSourceAddress}
310 This record is optional, and if it is specified, it will cause the Director
311 server (when initiating connections to a storage or file daemon) to source
312 its connections from the specified address. Only a single IP address may be
313 specified. If this record is not specified, the Director server will source
314 its outgoing connections according to the system routing table (the default).
316 \item[Statistics Retention = \lt{}time\gt{}]
317 \index[dir]{StatisticsRetention}
318 \index[dir]{Directive!StatisticsRetention}
319 \label{PruneStatistics}
321 The \texttt{Statistics Retention} directive defines the length of time that
322 Bacula will keep statistics job records in the Catalog database after the
323 Job End time. (In \texttt{JobHistory} table) When this time period expires,
324 and if user runs \texttt{prune stats} command, Bacula will prune (remove)
325 Job records that are older than the specified period.
327 Theses statistics records aren't use for restore purpose, but mainly for
328 capacity planning, billings, etc. See \ilink{Statistics chapter} for
329 additional information.
331 See the \ilink{ Configuration chapter}{Time} of this manual for additional
332 details of time specification.
334 The default is 5 years.
336 \item[VerId = \lt{}string\gt{}]
337 \index[dir]{Directive!VerId}
338 where \lt{}string\gt{} is an identifier which can be used for support purpose.
339 This string is displayed using the \texttt{version} command.
341 \item[MaximumConsoleConnections = \lt{}number\gt{}]
342 \index[dir]{MaximumConsoleConnections}
343 \index[dir]{Directive!MaximumConsoleConnections}
345 where \lt{}number\gt{} is the maximum number of Console Connections that
346 could run concurrently. The default is set to 20, but you may set it to a
351 The following is an example of a valid Director resource definition:
357 WorkingDirectory = "$HOME/bacula/bin/working"
358 Password = UA_password
359 PidDirectory = "$HOME/bacula/bin/working"
360 QueryFile = "$HOME/bacula/bin/query.sql"
366 \section{The Job Resource}
368 \index[general]{Resource!Job}
369 \index[general]{Job Resource}
371 The Job resource defines a Job (Backup, Restore, ...) that Bacula must
372 perform. Each Job resource definition contains the name of a Client and
373 a FileSet to backup, the Schedule for the Job, where the data
374 are to be stored, and what media Pool can be used. In effect, each Job
375 resource must specify What, Where, How, and When or FileSet, Storage,
376 Backup/Restore/Level, and Schedule respectively. Note, the FileSet must
377 be specified for a restore job for historical reasons, but it is no longer used.
379 Only a single type ({\bf Backup}, {\bf Restore}, ...) can be specified for any
380 job. If you want to backup multiple FileSets on the same Client or multiple
381 Clients, you must define a Job for each one.
383 Note, you define only a single Job to do the Full, Differential, and
384 Incremental backups since the different backup levels are tied together by
385 a unique Job name. Normally, you will have only one Job per Client, but
386 if a client has a really huge number of files (more than several million),
387 you might want to split it into to Jobs each with a different FileSet
388 covering only part of the total files.
390 Multiple Storage daemons are not currently supported for Jobs, so if
391 you do want to use multiple storage daemons, you will need to create
392 a different Job and ensure that for each Job that the combination of
393 Client and FileSet are unique. The Client and FileSet are what Bacula
394 uses to restore a client, so if there are multiple Jobs with the same
395 Client and FileSet or multiple Storage daemons that are used, the
396 restore will not work. This problem can be resolved by defining multiple
397 FileSet definitions (the names must be different, but the contents of
398 the FileSets may be the same).
405 \index[dir]{Directive!Job}
406 Start of the Job resource. At least one Job resource is required.
408 \item [Name = \lt{}name\gt{}]
410 \index[dir]{Directive!Name}
411 The Job name. This name can be specified on the {\bf Run} command in the
412 console program to start a job. If the name contains spaces, it must be
413 specified between quotes. It is generally a good idea to give your job the
414 same name as the Client that it will backup. This permits easy
415 identification of jobs.
417 When the job actually runs, the unique Job Name will consist of the name you
418 specify here followed by the date and time the job was scheduled for
419 execution. This directive is required.
421 \item [Enabled = \lt{}yes\vb{}no\gt{}]
423 \index[dir]{Directive!Enable}
424 This directive allows you to enable or disable automatic execution
425 via the scheduler of a Job.
427 \item [Type = \lt{}job-type\gt{}]
429 \index[dir]{Directive!Type}
430 The {\bf Type} directive specifies the Job type, which may be one of the
431 following: {\bf Backup}, {\bf Restore}, {\bf Verify}, or {\bf Admin}. This
432 directive is required. Within a particular Job Type, there are also Levels
433 as discussed in the next item.
439 Run a backup Job. Normally you will have at least one Backup job for each
440 client you want to save. Normally, unless you turn off cataloging, most all
441 the important statistics and data concerning files backed up will be placed
446 Run a restore Job. Normally, you will specify only one Restore job
447 which acts as a sort of prototype that you will modify using the console
448 program in order to perform restores. Although certain basic
449 information from a Restore job is saved in the catalog, it is very
450 minimal compared to the information stored for a Backup job -- for
451 example, no File database entries are generated since no Files are
454 {\bf Restore} jobs cannot be
455 automatically started by the scheduler as is the case for Backup, Verify
456 and Admin jobs. To restore files, you must use the {\bf restore} command
462 Run a verify Job. In general, {\bf verify} jobs permit you to compare the
463 contents of the catalog to the file system, or to what was backed up. In
464 addition, to verifying that a tape that was written can be read, you can
465 also use {\bf verify} as a sort of tripwire intrusion detection.
469 Run an admin Job. An {\bf Admin} job can be used to periodically run catalog
470 pruning, if you do not want to do it at the end of each {\bf Backup} Job.
471 Although an Admin job is recorded in the catalog, very little data is saved.
476 \item [Level = \lt{}job-level\gt{}]
478 \index[dir]{Directive!Level}
479 The Level directive specifies the default Job level to be run. Each
480 different Job Type (Backup, Restore, ...) has a different set of Levels
481 that can be specified. The Level is normally overridden by a different
482 value that is specified in the {\bf Schedule} resource. This directive
483 is not required, but must be specified either by a {\bf Level} directive
484 or as an override specified in the {\bf Schedule} resource.
486 For a {\bf Backup} Job, the Level may be one of the following:
492 When the Level is set to Full all files in the FileSet whether or not
493 they have changed will be backed up.
496 \index[dir]{Incremental}
497 When the Level is set to Incremental all files specified in the FileSet
498 that have changed since the last successful backup of the the same Job
499 using the same FileSet and Client, will be backed up. If the Director
500 cannot find a previous valid Full backup then the job will be upgraded
501 into a Full backup. When the Director looks for a valid backup record
502 in the catalog database, it looks for a previous Job with:
505 \item The same Job name.
506 \item The same Client name.
507 \item The same FileSet (any change to the definition of the FileSet such as
508 adding or deleting a file in the Include or Exclude sections constitutes a
510 \item The Job was a Full, Differential, or Incremental backup.
511 \item The Job terminated normally (i.e. did not fail or was not canceled).
512 \item The Job started no longer ago than {\bf Max Full Interval}.
515 If all the above conditions do not hold, the Director will upgrade the
516 Incremental to a Full save. Otherwise, the Incremental backup will be
517 performed as requested.
519 The File daemon (Client) decides which files to backup for an
520 Incremental backup by comparing start time of the prior Job (Full,
521 Differential, or Incremental) against the time each file was last
522 "modified" (st\_mtime) and the time its attributes were last
523 "changed"(st\_ctime). If the file was modified or its attributes
524 changed on or after this start time, it will then be backed up.
526 Some virus scanning software may change st\_ctime while
527 doing the scan. For example, if the virus scanning program attempts to
528 reset the access time (st\_atime), which Bacula does not use, it will
529 cause st\_ctime to change and hence Bacula will backup the file during
530 an Incremental or Differential backup. In the case of Sophos virus
531 scanning, you can prevent it from resetting the access time (st\_atime)
532 and hence changing st\_ctime by using the {\bf \verb:--:no-reset-atime}
533 option. For other software, please see their manual.
535 When Bacula does an Incremental backup, all modified files that are
536 still on the system are backed up. However, any file that has been
537 deleted since the last Full backup remains in the Bacula catalog,
538 which means that if between a Full save and the time you do a
539 restore, some files are deleted, those deleted files will also be
540 restored. The deleted files will no longer appear in the catalog
541 after doing another Full save.
543 In addition, if you move a directory rather than copy it, the files in
544 it do not have their modification time (st\_mtime) or their attribute
545 change time (st\_ctime) changed. As a consequence, those files will
546 probably not be backed up by an Incremental or Differential backup which
547 depend solely on these time stamps. If you move a directory, and wish
548 it to be properly backed up, it is generally preferable to copy it, then
551 However, to manage deleted files or directories changes in the
552 catalog during an Incremental backup you can use \texttt{accurate}
553 mode. This is quite memory consuming process. See \ilink{Accurate
554 mode}{accuratemode} for more details.
557 \index[dir]{Differential}
558 When the Level is set to Differential
559 all files specified in the FileSet that have changed since the last
560 successful Full backup of the same Job will be backed up.
561 If the Director cannot find a
562 valid previous Full backup for the same Job, FileSet, and Client,
563 backup, then the Differential job will be upgraded into a Full backup.
564 When the Director looks for a valid Full backup record in the catalog
565 database, it looks for a previous Job with:
568 \item The same Job name.
569 \item The same Client name.
570 \item The same FileSet (any change to the definition of the FileSet such as
571 adding or deleting a file in the Include or Exclude sections constitutes a
573 \item The Job was a FULL backup.
574 \item The Job terminated normally (i.e. did not fail or was not canceled).
575 \item The Job started no longer ago than {\bf Max Full Interval}.
578 If all the above conditions do not hold, the Director will upgrade the
579 Differential to a Full save. Otherwise, the Differential backup will be
580 performed as requested.
582 The File daemon (Client) decides which files to backup for a
583 differential backup by comparing the start time of the prior Full backup
584 Job against the time each file was last "modified" (st\_mtime) and the
585 time its attributes were last "changed" (st\_ctime). If the file was
586 modified or its attributes were changed on or after this start time, it
587 will then be backed up. The start time used is displayed after the {\bf
588 Since} on the Job report. In rare cases, using the start time of the
589 prior backup may cause some files to be backed up twice, but it ensures
590 that no change is missed. As with the Incremental option, you should
591 ensure that the clocks on your server and client are synchronized or as
592 close as possible to avoid the possibility of a file being skipped.
593 Note, on versions 1.33 or greater Bacula automatically makes the
594 necessary adjustments to the time between the server and the client so
595 that the times Bacula uses are synchronized.
597 When Bacula does a Differential backup, all modified files that are
598 still on the system are backed up. However, any file that has been
599 deleted since the last Full backup remains in the Bacula catalog, which
600 means that if between a Full save and the time you do a restore, some
601 files are deleted, those deleted files will also be restored. The
602 deleted files will no longer appear in the catalog after doing another
603 Full save. However, to remove deleted files from the catalog during a
604 Differential backup is quite a time consuming process and not currently
605 implemented in Bacula. It is, however, a planned future feature.
607 As noted above, if you move a directory rather than copy it, the
608 files in it do not have their modification time (st\_mtime) or
609 their attribute change time (st\_ctime) changed. As a
610 consequence, those files will probably not be backed up by an
611 Incremental or Differential backup which depend solely on these
612 time stamps. If you move a directory, and wish it to be
613 properly backed up, it is generally preferable to copy it, then
614 delete the original. Alternatively, you can move the directory, then
615 use the {\bf touch} program to update the timestamps.
617 %% TODO: merge this with incremental
618 However, to manage deleted files or directories changes in the
619 catalog during an Differential backup you can use \texttt{accurate}
620 mode. This is quite memory consuming process. See \ilink{Accurate
621 mode}{accuratemode} for more details.
623 Every once and a while, someone asks why we need Differential
624 backups as long as Incremental backups pickup all changed files.
625 There are possibly many answers to this question, but the one
626 that is the most important for me is that a Differential backup
628 all the Incremental and Differential backups since the last Full backup
629 into a single Differential backup. This has two effects: 1. It gives
630 some redundancy since the old backups could be used if the merged backup
631 cannot be read. 2. More importantly, it reduces the number of Volumes
632 that are needed to do a restore effectively eliminating the need to read
633 all the volumes on which the preceding Incremental and Differential
634 backups since the last Full are done.
638 For a {\bf Restore} Job, no level needs to be specified.
640 For a {\bf Verify} Job, the Level may be one of the following:
645 \index[dir]{InitCatalog}
646 does a scan of the specified {\bf FileSet} and stores the file
647 attributes in the Catalog database. Since no file data is saved, you
648 might ask why you would want to do this. It turns out to be a very
649 simple and easy way to have a {\bf Tripwire} like feature using {\bf
650 Bacula}. In other words, it allows you to save the state of a set of
651 files defined by the {\bf FileSet} and later check to see if those files
652 have been modified or deleted and if any new files have been added.
653 This can be used to detect system intrusion. Typically you would
654 specify a {\bf FileSet} that contains the set of system files that
655 should not change (e.g. /sbin, /boot, /lib, /bin, ...). Normally, you
656 run the {\bf InitCatalog} level verify one time when your system is
657 first setup, and then once again after each modification (upgrade) to
658 your system. Thereafter, when your want to check the state of your
659 system files, you use a {\bf Verify} {\bf level = Catalog}. This
660 compares the results of your {\bf InitCatalog} with the current state of
665 Compares the current state of the files against the state previously
666 saved during an {\bf InitCatalog}. Any discrepancies are reported. The
667 items reported are determined by the {\bf verify} options specified on
668 the {\bf Include} directive in the specified {\bf FileSet} (see the {\bf
669 FileSet} resource below for more details). Typically this command will
670 be run once a day (or night) to check for any changes to your system
673 Please note! If you run two Verify Catalog jobs on the same client at
674 the same time, the results will certainly be incorrect. This is because
675 Verify Catalog modifies the Catalog database while running in order to
678 \item [VolumeToCatalog]
679 \index[dir]{VolumeToCatalog}
680 This level causes Bacula to read the file attribute data written to the
681 Volume from the last Job. The file attribute data are compared to the
682 values saved in the Catalog database and any differences are reported.
683 This is similar to the {\bf Catalog} level except that instead of
684 comparing the disk file attributes to the catalog database, the
685 attribute data written to the Volume is read and compared to the catalog
686 database. Although the attribute data including the signatures (MD5 or
687 SHA1) are compared, the actual file data is not compared (it is not in
690 Please note! If you run two Verify VolumeToCatalog jobs on the same
691 client at the same time, the results will certainly be incorrect. This
692 is because the Verify VolumeToCatalog modifies the Catalog database
695 \item [DiskToCatalog]
696 \index[dir]{DiskToCatalog}
697 This level causes Bacula to read the files as they currently are on
698 disk, and to compare the current file attributes with the attributes
699 saved in the catalog from the last backup for the job specified on the
700 {\bf VerifyJob} directive. This level differs from the {\bf Catalog}
701 level described above by the fact that it doesn't compare against a
702 previous Verify job but against a previous backup. When you run this
703 level, you must supply the verify options on your Include statements.
704 Those options determine what attribute fields are compared.
706 This command can be very useful if you have disk problems because it
707 will compare the current state of your disk against the last successful
708 backup, which may be several jobs.
710 Note, the current implementation (1.32c) does not identify files that
714 \item [Accurate = \lt{}yes\vb{}no\gt{}]
715 \index[dir]{Accurate}
716 In accurate mode, the File daemon knowns exactly which files were present
717 after the last backup. So it is able to handle deleted or renamed files.
719 When restoring a FileSet for a specified date (including "most
720 recent"), Bacula is able to restore exactly the files and
721 directories that existed at the time of the last backup prior to
722 that date including ensuring that deleted files are actually deleted,
723 and renamed directories are restored properly.
725 In this mode, the File daemon must keep data concerning all files in
726 memory. So you do not have sufficient memory, the restore may
727 either be terribly slow or fail.
729 %% $$ memory = \sum_{i=1}^{n}(strlen(path_i + file_i) + sizeof(CurFile))$$
731 For 500.000 files (a typical desktop linux system), it will require
732 approximately 64 Megabytes of RAM on your File daemon to hold the
733 required information.
735 \item [Verify Job = \lt{}Job-Resource-Name\gt{}]
736 \index[dir]{Verify Job}
737 \index[dir]{Directive!Verify Job}
738 If you run a verify job without this directive, the last job run will be
739 compared with the catalog, which means that you must immediately follow
740 a backup by a verify command. If you specify a {\bf Verify Job} Bacula
741 will find the last job with that name that ran. This permits you to run
742 all your backups, then run Verify jobs on those that you wish to be
743 verified (most often a {\bf VolumeToCatalog}) so that the tape just
746 \item [JobDefs = \lt{}JobDefs-Resource-Name\gt{}]
748 \index[dir]{Directive!JobDefs}
749 If a JobDefs-Resource-Name is specified, all the values contained in the
750 named JobDefs resource will be used as the defaults for the current Job.
751 Any value that you explicitly define in the current Job resource, will
752 override any defaults specified in the JobDefs resource. The use of
753 this directive permits writing much more compact Job resources where the
754 bulk of the directives are defined in one or more JobDefs. This is
755 particularly useful if you have many similar Jobs but with minor
756 variations such as different Clients. A simple example of the use of
757 JobDefs is provided in the default bacula-dir.conf file.
759 \item [Bootstrap = \lt{}bootstrap-file\gt{}]
760 \index[dir]{Bootstrap}
761 \index[dir]{Directive!Bootstrap}
762 The Bootstrap directive specifies a bootstrap file that, if provided,
763 will be used during {\bf Restore} Jobs and is ignored in other Job
764 types. The {\bf bootstrap} file contains the list of tapes to be used
765 in a restore Job as well as which files are to be restored.
766 Specification of this directive is optional, and if specified, it is
767 used only for a restore job. In addition, when running a Restore job
768 from the console, this value can be changed.
770 If you use the {\bf Restore} command in the Console program, to start a
771 restore job, the {\bf bootstrap} file will be created automatically from
772 the files you select to be restored.
774 For additional details of the {\bf bootstrap} file, please see
775 \ilink{Restoring Files with the Bootstrap File}{BootstrapChapter} chapter
778 \label{writebootstrap}
779 \item [Write Bootstrap = \lt{}bootstrap-file-specification\gt{}]
780 \index[dir]{Write Bootstrap}
781 \index[dir]{Directive!Write Bootstrap}
782 The {\bf writebootstrap} directive specifies a file name where Bacula
783 will write a {\bf bootstrap} file for each Backup job run. This
784 directive applies only to Backup Jobs. If the Backup job is a Full
785 save, Bacula will erase any current contents of the specified file
786 before writing the bootstrap records. If the Job is an Incremental
788 save, Bacula will append the current bootstrap record to the end of the
791 Using this feature, permits you to constantly have a bootstrap file that
792 can recover the current state of your system. Normally, the file
793 specified should be a mounted drive on another machine, so that if your
794 hard disk is lost, you will immediately have a bootstrap record
795 available. Alternatively, you should copy the bootstrap file to another
796 machine after it is updated. Note, it is a good idea to write a separate
797 bootstrap file for each Job backed up including the job that backs up
798 your catalog database.
800 If the {\bf bootstrap-file-specification} begins with a vertical bar
801 (\verb+|+), Bacula will use the specification as the name of a program to which
802 it will pipe the bootstrap record. It could for example be a shell
803 script that emails you the bootstrap record.
805 On versions 1.39.22 or greater, before opening the file or executing the
806 specified command, Bacula performs
807 \ilink{character substitution}{character substitution} like in RunScript
808 directive. To automatically manage your bootstrap files, you can use
809 this in your {\bf JobDefs} resources:
812 Write Bootstrap = "%c_%n.bsr"
817 For more details on using this file, please see the chapter entitled
818 \ilink{The Bootstrap File}{BootstrapChapter} of this manual.
820 \item [Client = \lt{}client-resource-name\gt{}]
822 \index[dir]{Directive!Client}
823 The Client directive specifies the Client (File daemon) that will be used in
824 the current Job. Only a single Client may be specified in any one Job. The
825 Client runs on the machine to be backed up, and sends the requested files to
826 the Storage daemon for backup, or receives them when restoring. For
827 additional details, see the
828 \ilink{Client Resource section}{ClientResource2} of this chapter.
829 This directive is required.
831 \item [FileSet = \lt{}FileSet-resource-name\gt{}]
833 \index[dir]{Directive!FileSet}
834 The FileSet directive specifies the FileSet that will be used in the
835 current Job. The FileSet specifies which directories (or files) are to
836 be backed up, and what options to use (e.g. compression, ...). Only a
837 single FileSet resource may be specified in any one Job. For additional
838 details, see the \ilink{FileSet Resource section}{FileSetResource} of
839 this chapter. This directive is required.
841 \item [Base = \lt{}job-resource-name, ...\gt{}]
843 \index[dir]{Directive!Base}
844 The Base directive permits to specify the list of jobs that will be used during
845 Full backup as base. This directive is optional. See the \ilink{Base Job
846 chapter}{basejobs} for more information.
848 \item [Messages = \lt{}messages-resource-name\gt{}]
849 \index[dir]{Messages}
850 \index[dir]{Directive!Messages}
851 The Messages directive defines what Messages resource should be used for
852 this job, and thus how and where the various messages are to be
853 delivered. For example, you can direct some messages to a log file, and
854 others can be sent by email. For additional details, see the
855 \ilink{Messages Resource}{MessagesChapter} Chapter of this manual. This
856 directive is required.
858 \item [Pool = \lt{}pool-resource-name\gt{}]
860 \index[dir]{Directive!Pool}
861 The Pool directive defines the pool of Volumes where your data can be
862 backed up. Many Bacula installations will use only the {\bf Default}
863 pool. However, if you want to specify a different set of Volumes for
864 different Clients or different Jobs, you will probably want to use
865 Pools. For additional details, see the \ilink{Pool Resource
866 section}{PoolResource} of this chapter. This directive is required.
868 \item [Full Backup Pool = \lt{}pool-resource-name\gt{}]
869 \index[dir]{Full Backup Pool}
870 \index[dir]{Directive!Full Backup Pool}
871 The {\it Full Backup Pool} specifies a Pool to be used for Full backups.
872 It will override any Pool specification during a Full backup. This
873 directive is optional.
875 \item [Differential Backup Pool = \lt{}pool-resource-name\gt{}]
876 \index[dir]{Differential Backup Pool}
877 \index[dir]{Directive!Differential Backup Pool}
878 The {\it Differential Backup Pool} specifies a Pool to be used for
879 Differential backups. It will override any Pool specification during a
880 Differential backup. This directive is optional.
882 \item [Incremental Backup Pool = \lt{}pool-resource-name\gt{}]
883 \index[dir]{Incremental Backup Pool}
884 \index[dir]{Directive!Incremental Backup Pool}
885 The {\it Incremental Backup Pool} specifies a Pool to be used for
886 Incremental backups. It will override any Pool specification during an
887 Incremental backup. This directive is optional.
889 \item [Schedule = \lt{}schedule-name\gt{}]
890 \index[dir]{Schedule}
891 \index[dir]{Directive!Schedule}
892 The Schedule directive defines what schedule is to be used for the Job.
893 The schedule in turn determines when the Job will be automatically
894 started and what Job level (i.e. Full, Incremental, ...) is to be run.
895 This directive is optional, and if left out, the Job can only be started
896 manually using the Console program. Although you may specify only a
897 single Schedule resource for any one job, the Schedule resource may
898 contain multiple {\bf Run} directives, which allow you to run the Job at
899 many different times, and each {\bf run} directive permits overriding
900 the default Job Level Pool, Storage, and Messages resources. This gives
901 considerable flexibility in what can be done with a single Job. For
902 additional details, see the \ilink{Schedule Resource
903 Chapter}{ScheduleResource} of this manual.
906 \item [Storage = \lt{}storage-resource-name\gt{}]
908 \index[dir]{Directive!Storage}
909 The Storage directive defines the name of the storage services where you
910 want to backup the FileSet data. For additional details, see the
911 \ilink{Storage Resource Chapter}{StorageResource2} of this manual.
912 The Storage resource may also be specified in the Job's Pool resource,
913 in which case the value in the Pool resource overrides any value
914 in the Job. This Storage resource definition is not required by either
915 the Job resource or in the Pool, but it must be specified in
916 one or the other, if not an error will result.
918 \item [Max Start Delay = \lt{}time\gt{}]
919 \index[dir]{Max Start Delay}
920 \index[dir]{Directive!Max Start Delay}
921 The time specifies the maximum delay between the scheduled time and the
922 actual start time for the Job. For example, a job can be scheduled to
923 run at 1:00am, but because other jobs are running, it may wait to run.
924 If the delay is set to 3600 (one hour) and the job has not begun to run
925 by 2:00am, the job will be canceled. This can be useful, for example,
926 to prevent jobs from running during day time hours. The default is 0
927 which indicates no limit.
929 \item [Max Run Time = \lt{}time\gt{}]
930 \index[dir]{Max Run Time}
931 \index[dir]{Directive!Max Run Time}
932 The time specifies the maximum allowed time that a job may run, counted
933 from when the job starts, ({\bf not} necessarily the same as when the
936 \item [Incremental|Differential Max Wait Time = \lt{}time\gt{}]
937 \index[dir]{Incremental Wait Run Time}
938 \index[dir]{Differential Wait Run Time}
939 \index[dir]{Directive!Differential Max Wait Time}
940 Theses directives have been deprecated in favor of
941 \texttt{Incremental|Differential Max Run Time} since bacula 2.3.18.
943 \item [Incremental Max Run Time = \lt{}time\gt{}]
944 \index[dir]{Incremental Max Run Time}
945 \index[dir]{Directive!Incremental Max Run Time}
946 The time specifies the maximum allowed time that an Incremental backup job may
947 run, counted from when the job starts, ({\bf not} necessarily the same as when
948 the job was scheduled).
950 \item [Differential Max Wait Time = \lt{}time\gt{}]
951 \index[dir]{Differential Max Run Time}
952 \index[dir]{Directive!Differential Max Run Time}
953 The time specifies the maximum allowed time that a Differential backup job may
954 run, counted from when the job starts, ({\bf not} necessarily the same as when
955 the job was scheduled).
957 \item [Max Run Sched Time = \lt{}time\gt{}]
958 \index[dir]{Max Run Sched Time}
959 \index[dir]{Directive!Max Run Sched Time}
961 The time specifies the maximum allowed time that a job may run, counted from
962 when the job was scheduled. This can be useful to prevent jobs from running
963 during working hours. We can see it like \texttt{Max Start Delay + Max Run
966 \item [Max Wait Time = \lt{}time\gt{}]
967 \index[dir]{Max Wait Time}
968 \index[dir]{Directive!Max Wait Time}
969 The time specifies the maximum allowed time that a job may block waiting
970 for a resource (such as waiting for a tape to be mounted, or waiting for
971 the storage or file daemons to perform their duties), counted from the
972 when the job starts, ({\bf not} necessarily the same as when the job was
973 scheduled). This directive works as expected since bacula 2.3.18.

983 \item [Max Full Interval = \lt{}time\gt{}]
984 \index[dir]{Max Full Interval}
985 \index[dir]{Directive!Max Full Interval}
986 The time specifies the maximum allowed age (counting from start time) of
987 the most recent successful Full backup that is required in order to run
988 Incremental or Differential backup jobs. If the most recent Full backup
989 is older than this interval, Incremental and Differential backups will be
990 upgraded to Full backups automatically. If this directive is not present,
991 or specified as 0, then the age of the previous Full backup is not

995 \item [Prefer Mounted Volumes = \lt{}yes\vb{}no\gt{}]
996 \index[dir]{Prefer Mounted Volumes}
997 \index[dir]{Directive!Prefer Mounted Volumes}
998 If the Prefer Mounted Volumes directive is set to {\bf yes} (default
999 yes), the Storage daemon is requested to select either an Autochanger or
1000 a drive with a valid Volume already mounted in preference to a drive
1001 that is not ready. This means that all jobs will attempt to append
1002 to the same Volume (providing the Volume is appropriate -- right Pool,
1003 ... for that job), unless you are using multiple pools.
1004 If no drive with a suitable Volume is available, it
1005 will select the first available drive. Note, any Volume that has
1006 been requested to be mounted, will be considered valid as a mounted
1007 volume by another job. This if multiple jobs start at the same time
1008 and they all prefer mounted volumes, the first job will request the
1009 mount, and the other jobs will use the same volume.
1011 If the directive is set to {\bf no}, the Storage daemon will prefer
1012 finding an unused drive, otherwise, each job started will append to the
1013 same Volume (assuming the Pool is the same for all jobs). Setting
1014 Prefer Mounted Volumes to no can be useful for those sites
1015 with multiple drive autochangers that prefer to maximize backup
1016 throughput at the expense of using additional drives and Volumes.
1017 This means that the job will prefer to use an unused drive rather
1018 than use a drive that is already in use.
1020 Despite the above, we recommend against setting this directive to
1022 it tends to add a lot of swapping of Volumes between the different
1023 drives and can easily lead to deadlock situations in the Storage
1024 daemon. We will accept bug reports against it, but we cannot guarantee
1025 that we will be able to fix the problem in a reasonable time.
1027 A better alternative for using multiple drives is to use multiple
1028 pools so that Bacula will be forced to mount Volumes from those Pools
1029 on different drives.
1031 \item [Prune Jobs = \lt{}yes\vb{}no\gt{}]
1032 \index[dir]{Prune Jobs}
1033 \index[dir]{Directive!Prune Jobs}
1034 Normally, pruning of Jobs from the Catalog is specified on a Pool by
1035 Pool basis in the Pool resource with the {\bf AutoPrune} directive.
1036 If this directive is specified (not normally) and the value is {\bf
1037 yes}, it will override the value specified in the Pool resource. The
1038 default is {\bf no}.
1041 \item [Prune Files = \lt{}yes\vb{}no\gt{}]
1042 \index[dir]{Prune Files}
1043 \index[dir]{Directive!Prune Files}
1044 Normally, pruning of Files from the Catalog is specified on a Pool by
1045 Pool basis in the Pool resource with the {\bf AutoPrune} directive.
1046 If this directive is specified (not normally) and the value is {\bf
1047 yes}, it will override the value specified in the Pool resource. The
1048 default is {\bf no}.
1050 \item [Prune Volumes = \lt{}yes\vb{}no\gt{}]
1051 \index[dir]{Prune Volumes}
1052 \index[dir]{Directive!Prune Volumes}
1053 Normally, pruning of Volumes from the Catalog is specified on a Pool
1054 by Pool basis in the Pool resource with the {\bf AutoPrune}
1055 directive. If this directive is specified (not normally) and the value
1056 is {\bf yes}, it will override the value specified in the Pool
1057 resource. The default is {\bf no}.
1059 \item [RunScript \{\lt{}body-of-runscript\gt{}\}]
1060 \index[dir]{RunScript}
1061 \index[dir]{Directive!Run Script}
1063 The RunScript directive behaves like a resource in that it
1064 requires opening and closing braces around a number of directives
1065 that make up the body of the runscript.
1067 The specified {\bf Command} (see below for details) is run as an external
1068 program prior or after the current Job. This is optional. By default, the
1069 program is executed on the Client side like in \texttt{ClientRunXXXJob}.
1071 \textbf{Console} options are special commands that are sent to the director instead
1072 of the OS. At this time, console command ouputs are redirected to log with
1075 You can use following console command : \texttt{delete}, \texttt{disable},
1076 \texttt{enable}, \texttt{estimate}, \texttt{list}, \texttt{llist},
1077 \texttt{memory}, \texttt{prune}, \texttt{purge}, \texttt{reload},
1078 \texttt{status}, \texttt{setdebug}, \texttt{show}, \texttt{time},
1079 \texttt{trace}, \texttt{update}, \texttt{version}, \texttt{.client},
1080 \texttt{.jobs}, \texttt{.pool}, \texttt{.storage}. See console chapter for
1081 more information. You need to specify needed information on command line, nothing
1082 will be prompted. Example :
1085 Console = "prune files client=%c"
1086 Console = "update stats age=3"
1089 You can specify more than one Command/Console option per RunScript.
1091 You can use following options may be specified in the body
1094 \begin{tabular}{|c|c|c|l}
1095 Options & Value & Default & Information \\
1098 Runs On Success & Yes/No & {\it Yes} & Run command if JobStatus is successful\\
1100 Runs On Failure & Yes/No & {\it No} & Run command if JobStatus isn't successful\\
1102 Runs On Client & Yes/No & {\it Yes} & Run command on client\\
1104 Runs When & Before|After|Always|\textsl{AfterVSS} & {\it Never} & When run commands\\
1106 Fail Job On Error & Yes/No & {\it Yes} & Fail job if script returns
1107 something different from 0 \\
1109 Command & & & Path to your script\\
1111 Console & & & Console command\\
1116 Any output sent by the command to standard output will be included in the
1117 Bacula job report. The command string must be a valid program name or name
1120 In addition, the command string is parsed then fed to the OS,
1121 which means that the path will be searched to execute your specified
1122 command, but there is no shell interpretation, as a consequence, if you
1123 invoke complicated commands or want any shell features such as redirection
1124 or piping, you must call a shell script and do it inside that script.
1126 Before submitting the specified command to the operating system, Bacula
1127 performs character substitution of the following characters:
1129 \label{character substitution}
1134 %d = Director's name
1135 %e = Job Exit Status
1141 %t = Job type (Backup, ...)
1142 %v = Volume name (Only on director side)
1147 The Job Exit Status code \%e edits the following values:
1149 \index[dir]{Exit Status}
1156 \item Unknown term code
1159 Thus if you edit it on a command line, you will need to enclose
1160 it within some sort of quotes.
1163 You can use these following shortcuts:\\
1165 \begin{tabular}{|c|c|c|c|c|c}
1166 Keyword & RunsOnSuccess & RunsOnFailure & FailJobOnError & Runs On Client & RunsWhen \\
1168 Run Before Job & & & Yes & No & Before \\
1170 Run After Job & Yes & No & & No & After \\
1172 Run After Failed Job & No & Yes & & No & After \\
1174 Client Run Before Job & & & Yes & Yes & Before \\
1176 Client Run After Job & Yes & No & & Yes & After \\
1184 Command = "/etc/init.d/apache stop"
1190 Command = "/etc/init.d/apache start"
1194 {\bf Notes about ClientRunBeforeJob}
1196 For compatibility reasons, with this shortcut, the command is executed
1197 directly when the client recieve it. And if the command is in error, other
1198 remote runscripts will be discarded. To be sure that all commands will be
1199 sent and executed, you have to use RunScript syntax.
1201 {\bf Special Windows Considerations}
1203 You can run scripts just after snapshots initializations with
1204 \textsl{AfterVSS} keyword.
1206 In addition, for a Windows client on version 1.33 and above, please take
1207 note that you must ensure a correct path to your script. The script or
1208 program can be a .com, .exe or a .bat file. If you just put the program
1209 name in then Bacula will search using the same rules that cmd.exe uses
1210 (current directory, Bacula bin directory, and PATH). It will even try the
1211 different extensions in the same order as cmd.exe.
1212 The command can be anything that cmd.exe or command.com will recognize
1213 as an executable file.
1215 However, if you have slashes in the program name then Bacula figures you
1216 are fully specifying the name, so you must also explicitly add the three
1217 character extension.
1219 The command is run in a Win32 environment, so Unix like commands will not
1220 work unless you have installed and properly configured Cygwin in addition
1221 to and separately from Bacula.
1223 The System \%Path\% will be searched for the command. (under the
1224 environment variable dialog you have have both System Environment and
1225 User Environment, we believe that only the System environment will be
1226 available to bacula-fd, if it is running as a service.)
1228 System environment variables can be referenced with \%var\% and
1229 used as either part of the command name or arguments.
1231 So if you have a script in the Bacula\\bin directory then the following lines
1236 Client Run Before Job = systemstate
1238 Client Run Before Job = systemstate.bat
1240 Client Run Before Job = "systemstate"
1242 Client Run Before Job = "systemstate.bat"
1244 ClientRunBeforeJob = "\"C:/Program Files/Bacula/systemstate.bat\""
1248 The outer set of quotes is removed when the configuration file is parsed.
1249 You need to escape the inner quotes so that they are there when the code
1250 that parses the command line for execution runs so it can tell what the
1256 ClientRunBeforeJob = "\"C:/Program Files/Software
1257 Vendor/Executable\" /arg1 /arg2 \"foo bar\""
1261 The special characters
1265 will need to be quoted,
1266 if they are part of a filename or argument.
1268 If someone is logged in, a blank "command" window running the commands
1269 will be present during the execution of the command.
1271 Some Suggestions from Phil Stracchino for running on Win32 machines with
1272 the native Win32 File daemon:
1275 \item You might want the ClientRunBeforeJob directive to specify a .bat
1276 file which runs the actual client-side commands, rather than trying
1277 to run (for example) regedit /e directly.
1278 \item The batch file should explicitly 'exit 0' on successful completion.
1279 \item The path to the batch file should be specified in Unix form:
1281 ClientRunBeforeJob = "c:/bacula/bin/systemstate.bat"
1283 rather than DOS/Windows form:
1285 ClientRunBeforeJob =
1287 "c:\textbackslash{}bacula\textbackslash{}bin\textbackslash{}systemstate.bat"
1291 For Win32, please note that there are certain limitations:
1293 ClientRunBeforeJob = "C:/Program Files/Bacula/bin/pre-exec.bat"
1295 Lines like the above do not work because there are limitations of
1296 cmd.exe that is used to execute the command.
1297 Bacula prefixes the string you supply with {\bf cmd.exe /c }. To test that
1298 your command works you should type {\bf cmd /c "C:/Program Files/test.exe"} at a
1299 cmd prompt and see what happens. Once the command is correct insert a
1300 backslash (\textbackslash{}) before each double quote ("), and
1301 then put quotes around the whole thing when putting it in
1302 the director's .conf file. You either need to have only one set of quotes
1303 or else use the short name and don't put quotes around the command path.
1305 Below is the output from cmd's help as it relates to the command line
1306 passed to the /c option.
1309 If /C or /K is specified, then the remainder of the command line after
1310 the switch is processed as a command line, where the following logic is
1311 used to process quote (") characters:
1315 If all of the following conditions are met, then quote characters
1316 on the command line are preserved:
1319 \item exactly two quote characters.
1320 \item no special characters between the two quote characters,
1321 where special is one of:
1325 \item there are one or more whitespace characters between the
1326 the two quote characters.
1327 \item the string between the two quote characters is the name
1328 of an executable file.
1331 \item Otherwise, old behavior is to see if the first character is
1332 a quote character and if so, strip the leading character and
1333 remove the last quote character on the command line, preserving
1334 any text after the last quote character.
1339 The following example of the use of the Client Run Before Job directive was
1340 submitted by a user:\\
1341 You could write a shell script to back up a DB2 database to a FIFO. The shell
1351 db2 BACKUP DATABASE mercuryd TO $DIR/dbpipe WITHOUT PROMPTING &
1356 The following line in the Job resource in the bacula-dir.conf file:
1359 Client Run Before Job = "su - mercuryd -c \"/u01/mercuryd/backupdb.sh '%t'
1364 When the job is run, you will get messages from the output of the script
1365 stating that the backup has started. Even though the command being run is
1366 backgrounded with \&, the job will block until the "db2 BACKUP DATABASE"
1367 command, thus the backup stalls.
1369 To remedy this situation, the "db2 BACKUP DATABASE" line should be changed to
1374 db2 BACKUP DATABASE mercuryd TO $DIR/dbpipe WITHOUT PROMPTING > $DIR/backup.log
1379 It is important to redirect the input and outputs of a backgrounded command to
1380 /dev/null to prevent the script from blocking.
1382 \item [Run Before Job = \lt{}command\gt{}]
1383 \index[dir]{Run Before Job}
1384 \index[dir]{Directive!Run Before Job}
1385 \index[dir]{Directive!Run Before Job}
1386 The specified {\bf command} is run as an external program prior to running the
1387 current Job. This directive is not required, but if it is defined, and if the
1388 exit code of the program run is non-zero, the current Bacula job will be
1392 Run Before Job = "echo test"
1394 it's equivalent to :
1397 Command = "echo test"
1403 Lutz Kittler has pointed out that using the RunBeforeJob directive can be a
1404 simple way to modify your schedules during a holiday. For example, suppose
1405 that you normally do Full backups on Fridays, but Thursday and Friday are
1406 holidays. To avoid having to change tapes between Thursday and Friday when
1407 no one is in the office, you can create a RunBeforeJob that returns a
1408 non-zero status on Thursday and zero on all other days. That way, the
1409 Thursday job will not run, and on Friday the tape you inserted on Wednesday
1410 before leaving will be used.
1412 \item [Run After Job = \lt{}command\gt{}]
1413 \index[dir]{Run After Job}
1414 \index[dir]{Directive!Run After Job}
1415 The specified {\bf command} is run as an external program if the current
1416 job terminates normally (without error or without being canceled). This
1417 directive is not required. If the exit code of the program run is
1418 non-zero, Bacula will print a warning message. Before submitting the
1419 specified command to the operating system, Bacula performs character
1420 substitution as described above for the {\bf RunScript} directive.
1422 An example of the use of this directive is given in the
1423 \ilink{Tips Chapter}{JobNotification} of this manual.
1425 See the {\bf Run After Failed Job} if you
1426 want to run a script after the job has terminated with any
1429 \item [Run After Failed Job = \lt{}command\gt{}]
1430 \index[dir]{Run After Job}
1431 \index[dir]{Directive!Run After Job}
1432 The specified {\bf command} is run as an external program after the current
1433 job terminates with any error status. This directive is not required. The
1434 command string must be a valid program name or name of a shell script. If
1435 the exit code of the program run is non-zero, Bacula will print a
1436 warning message. Before submitting the specified command to the
1437 operating system, Bacula performs character substitution as described above
1438 for the {\bf RunScript} directive. Note, if you wish that your script
1439 will run regardless of the exit status of the Job, you can use this :
1442 Command = "echo test"
1446 RunsOnSuccess = yes # default, you can drop this line

1457 This directive is the same as {\bf Run Before Job} except that the
1458 program is run on the client machine. The same restrictions apply to
1459 Unix systems as noted above for the {\bf RunScript}.
1461 \item [Client Run After Job = \lt{}command\gt{}]

1471 \item [Rerun Failed Levels = \lt{}yes\vb{}no\gt{}]
1472 \index[dir]{Rerun Failed Levels}
1473 \index[dir]{Directive!Rerun Failed Levels}
1474 If this directive is set to {\bf yes} (default no), and Bacula detects that
1475 a previous job at a higher level (i.e. Full or Differential) has failed,
1476 the current job level will be upgraded to the higher level. This is
1477 particularly useful for Laptops where they may often be unreachable, and if
1478 a prior Full save has failed, you wish the very next backup to be a Full
1479 save rather than whatever level it is started as.
1481 There are several points that must be taken into account when using this
1482 directive: first, a failed job is defined as one that has not terminated
1483 normally, which includes any running job of the same name (you need to
1484 ensure that two jobs of the same name do not run simultaneously);
1485 secondly, the {\bf Ignore FileSet Changes} directive is not considered
1486 when checking for failed levels, which means that any FileSet change will

1490 \index[dir]{Spool Data}
1491 \index[dir]{Directive!Spool Data}
1493 If this directive is set to {\bf yes} (default no), the Storage daemon will
1494 be requested to spool the data for this Job to disk rather than write it
1495 directly to tape. Once all the data arrives or the spool files' maximum sizes
1496 are reached, the data will be despooled and written to tape. Spooling data
1497 prevents tape shoe-shine (start and stop) during
1498 Incremental saves. If you are writing to a disk file using this option
1499 will probably just slow down the backup jobs.
1501 NOTE: When this directive is set to yes, Spool Attributes is also
1502 automatically set to yes.
1504 \item [Spool Attributes = \lt{}yes\vb{}no\gt{}]
1505 \index[dir]{Spool Attributes}

1508 \index[general]{slow}
1509 \index[dir]{Backups!slow}
1510 \index[general]{Backups!slow}
1511 The default is set to {\bf no}, which means that the File attributes are
1512 sent by the Storage daemon to the Director as they are stored on tape.
1513 However, if you want to avoid the possibility that database updates will
1514 slow down writing to the tape, you may want to set the value to {\bf
1515 yes}, in which case the Storage daemon will buffer the File attributes
1516 and Storage coordinates to a temporary file in the Working Directory,
1517 then when writing the Job data to the tape is completed, the attributes
1518 and storage coordinates will be sent to the Director.
1520 NOTE: When Spool Data is set to yes, Spool Attributes is also
1521 automatically set to yes.

1528 be restored in a different location from which they were saved. If {\bf
1529 Where} is not specified or is set to backslash ({\bf /}), the files will
1530 be restored to their original location. By default, we have set {\bf
1531 Where} in the example configuration files to be {\bf

1585 This directive applies only to a Restore job and specifies what happens
1586 when Bacula wants to restore a file or directory that already exists.
1587 You have the following options for {\bf replace-option}:
1593 when the file to be restored already exists, it is deleted and then
1594 replaced by the copy that was backed up. This is the default value.
1597 \index[dir]{ifnewer}
1598 if the backed up file (on tape) is newer than the existing file, the
1599 existing file is deleted and replaced by the back up.
1602 \index[dir]{ifolder}
1603 if the backed up file (on tape) is older than the existing file, the
1604 existing file is deleted and replaced by the back up.
1608 if the backed up file already exists, Bacula skips restoring this file.

1614 If a {\bf Where} path prefix is specified for a recovery job, apply it
1615 to absolute links as well. The default is {\bf No}. When set to {\bf
1616 Yes} then while restoring files to an alternate directory, any absolute
1617 soft links will also be modified to point to the new alternate
1618 directory. Normally this is what is desired -- i.e. everything is self
1619 consistent. However, if you wish to later move the files to their
1620 original locations, all files linked with absolute names will be broken.

1624 \index[dir]{Directive!Maximum Concurrent Jobs}
1625 where \lt{}number\gt{} is the maximum number of Jobs from the current

1627 only Jobs with the same name as the resource in which it appears. Any
1628 other restrictions on the maximum concurrent jobs such as in the
1629 Director, Client, or Storage resources will also apply in addition to
1630 the limit specified here. The default is set to 1, but you may set it
1631 to a larger number. We strongly recommend that you read the WARNING

1671 \label{fig:allowduplicatejobs}
1674 A duplicate job in the sense we use it here means a second or subsequent job
1675 with the same name starts. This happens most frequently when the first job
1676 runs longer than expected because no tapes are available.
1678 If this directive is enabled duplicate jobs will be run. If
1679 the directive is set to {\bf no} (default) then only one job of a given name
1680 may run at one time, and the action that Bacula takes to ensure only
1681 one job runs is determined by the other directives (see below).
1683 If {\bf Allow Duplicate Jobs} is set to {\bf no} and two jobs
1684 are present and none of the three directives given below permit
1685 cancelling a job, then the current job (the second one started)

1697 If \textbf{Allow Duplicates Jobs} is set to \textbf{no} and this
1698 directive is set to \textbf{yes}, Bacula will choose between duplicated
1699 jobs the one with the highest level. For example, it will cancel a
1700 previous Incremental to run a Full backup. It works only for Backup
1701 jobs. The default is \texttt{no}. If the levels of the duplicated

1725 \item [Run = \lt{}job-name\gt{}]
1727 \index[dir]{Directive!Run}
1728 \index[dir]{Clone a Job}
1729 The Run directive (not to be confused with the Run option in a
1730 Schedule) allows you to start other jobs or to clone jobs. By using the
1731 cloning keywords (see below), you can backup
1732 the same data (or almost the same data) to two or more drives
1733 at the same time. The {\bf job-name} is normally the same name
1734 as the current Job resource (thus creating a clone). However, it
1735 may be any Job name, so one job may start other related jobs.
1737 The part after the equal sign must be enclosed in double quotes,
1738 and can contain any string or set of options (overrides) that you
1739 can specify when entering the Run command from the console. For
1740 example {\bf storage=DDS-4 ...}. In addition, there are two special
1741 keywords that permit you to clone the current job. They are {\bf level=\%l}
1742 and {\bf since=\%s}. The \%l in the level keyword permits
1743 entering the actual level of the current job and the \%s in the since
1744 keyword permits putting the same time for comparison as used on the
1745 current job. Note, in the case of the since keyword, the \%s must be
1746 enclosed in double quotes, and thus they must be preceded by a backslash
1747 since they are already inside quotes. For example:
1750 run = "Nightly-backup level=%l since=\"%s\" storage=DDS-4"
1753 A cloned job will not start additional clones, so it is not
1754 possible to recurse.
1756 Please note that all cloned jobs, as specified in the Run directives are
1757 submitted for running before the original job is run (while it is being
1758 initialized). This means that any clone job will actually start before
1759 the original job, and may even block the original job from starting
1760 until the original job finishes unless you allow multiple simultaneous
1761 jobs. Even if you set a lower priority on the clone job, if no other
1762 jobs are running, it will start before the original job.
1764 If you are trying to prioritize jobs by using the clone feature (Run
1765 directive), you will find it much easier to do using a RunScript
1766 resource, or a RunBeforeJob directive.
1769 \item [Priority = \lt{}number\gt{}]
1770 \index[dir]{Priority}
1771 \index[dir]{Directive!Priority}
1772 This directive permits you to control the order in which your jobs will
1773 be run by specifying a positive non-zero number. The higher the number,
1774 the lower the job priority. Assuming you are not running concurrent jobs,
1775 all queued jobs of priority 1 will run before queued jobs of priority 2
1776 and so on, regardless of the original scheduling order.
1778 The priority only affects waiting jobs that are queued to run, not jobs
1779 that are already running. If one or more jobs of priority 2 are already
1780 running, and a new job is scheduled with priority 1, the currently
1781 running priority 2 jobs must complete before the priority 1 job is
1782 run, unless Allow Mixed Priority is set.
1784 The default priority is 10.
1786 If you want to run concurrent jobs you should
1787 keep these points in mind:
1790 \item See \ilink{Running Concurrent Jobs}{ConcurrentJobs} on how to setup
1793 \item Bacula concurrently runs jobs of only one priority at a time. It
1794 will not simultaneously run a priority 1 and a priority 2 job.
1796 \item If Bacula is running a priority 2 job and a new priority 1 job is
1797 scheduled, it will wait until the running priority 2 job terminates even
1798 if the Maximum Concurrent Jobs settings would otherwise allow two jobs
1799 to run simultaneously.
1801 \item Suppose that bacula is running a priority 2 job and a new priority 1
1802 job is scheduled and queued waiting for the running priority 2 job to
1803 terminate. If you then start a second priority 2 job, the waiting
1804 priority 1 job will prevent the new priority 2 job from running
1805 concurrently with the running priority 2 job. That is: as long as there
1806 is a higher priority job waiting to run, no new lower priority jobs will
1807 start even if the Maximum Concurrent Jobs settings would normally allow
1808 them to run. This ensures that higher priority jobs will be run as soon
1812 If you have several jobs of different priority, it may not best to start
1813 them at exactly the same time, because Bacula must examine them one at a
1814 time. If by Bacula starts a lower priority job first, then it will run
1815 before your high priority jobs. If you experience this problem, you may
1816 avoid it by starting any higher priority jobs a few seconds before lower
1817 priority ones. This insures that Bacula will examine the jobs in the
1818 correct order, and that your priority scheme will be respected.
1820 \label{AllowMixedPriority}
1821 \item [Allow Mixed Priority = \lt{}yes\vb{}no\gt{}]
1822 \index[dir]{Allow Mixed Priority}
1823 This directive is only implemented in version 2.5 and later. When
1824 set to {\bf yes} (default {\bf no}), this job may run even if lower
1825 priority jobs are already running. This means a high priority job
1826 will not have to wait for other jobs to finish before starting.
1827 The scheduler will only mix priorities when all running jobs have
1830 Note that only higher priority jobs will start early. Suppose the
1831 director will allow two concurrent jobs, and that two jobs with
1832 priority 10 are running, with two more in the queue. If a job with
1833 priority 5 is added to the queue, it will be run as soon as one of
1834 the running jobs finishes. However, new priority 10 jobs will not
1835 be run until the priority 5 job has finished.
1837 \label{WritePartAfterJob}
1838 \item [Write Part After Job = \lt{}yes\vb{}no\gt{}]
1839 \index[dir]{Write Part After Job}
1840 \index[dir]{Directive!Write Part After Job}
1841 This directive is only implemented in version 1.37 and later.
1842 If this directive is set to {\bf yes} (default {\bf no}), a new part file
1843 will be created after the job is finished.
1845 It should be set to {\bf yes} when writing to devices that require mount
1846 (for example DVD), so you are sure that the current part, containing
1847 this job's data, is written to the device, and that no data is left in
1848 the temporary file on the hard disk. However, on some media, like DVD+R
1849 and DVD-R, a lot of space (about 10Mb) is lost every time a part is
1850 written. So, if you run several jobs each after another, you could set
1851 this directive to {\bf no} for all jobs, except the last one, to avoid
1852 wasting too much space, but to ensure that the data is written to the
1853 medium when all jobs are finished.
1855 This directive is ignored with tape and FIFO devices.
1859 The following is an example of a valid Job resource definition:
1866 Level = Incremental # default
1868 FileSet="Minou Full Set"
1871 Schedule = "MinouWeeklyCycle"
1877 \section{The JobDefs Resource}
1878 \label{JobDefsResource}
1879 \index[general]{JobDefs Resource}
1880 \index[general]{Resource!JobDefs}
1882 The JobDefs resource permits all the same directives that can appear in a Job
1883 resource. However, a JobDefs resource does not create a Job, rather it can be
1884 referenced within a Job to provide defaults for that Job. This permits you to
1885 concisely define several nearly identical Jobs, each one referencing a JobDefs
1886 resource which contains the defaults. Only the changes from the defaults need to
1887 be mentioned in each Job.
1889 \section{The Schedule Resource}
1890 \label{ScheduleResource}
1891 \index[general]{Resource!Schedule}
1892 \index[general]{Schedule Resource}
1894 The Schedule resource provides a means of automatically scheduling a Job as
1895 well as the ability to override the default Level, Pool, Storage and Messages
1896 resources. If a Schedule resource is not referenced in a Job, the Job can only
1897 be run manually. In general, you specify an action to be taken and when.
1902 \index[dir]{Schedule}
1903 \index[dir]{Directive!Schedule}
1904 Start of the Schedule directives. No {\bf Schedule} resource is
1905 required, but you will need at least one if you want Jobs to be
1906 automatically started.
1908 \item [Name = \lt{}name\gt{}]
1910 \index[dir]{Directive!Name}
1911 The name of the schedule being defined. The Name directive is required.
1913 \item [Run = \lt{}Job-overrides\gt{} \lt{}Date-time-specification\gt{}]
1915 \index[dir]{Directive!Run}
1916 The Run directive defines when a Job is to be run, and what overrides if
1917 any to apply. You may specify multiple {\bf run} directives within a
1918 {\bf Schedule} resource. If you do, they will all be applied (i.e.
1919 multiple schedules). If you have two {\bf Run} directives that start at
1920 the same time, two Jobs will start at the same time (well, within one
1921 second of each other).
1923 The {\bf Job-overrides} permit overriding the Level, the Storage, the
1924 Messages, and the Pool specifications provided in the Job resource. In
1925 addition, the FullPool, the IncrementalPool, and the DifferentialPool
1926 specifications permit overriding the Pool specification according to
1927 what backup Job Level is in effect.
1929 By the use of overrides, you may customize a particular Job. For
1930 example, you may specify a Messages override for your Incremental
1931 backups that outputs messages to a log file, but for your weekly or
1932 monthly Full backups, you may send the output by email by using a
1933 different Messages override.
1935 {\bf Job-overrides} are specified as: {\bf keyword=value} where the
1936 keyword is Level, Storage, Messages, Pool, FullPool, DifferentialPool,
1937 or IncrementalPool, and the {\bf value} is as defined on the respective
1938 directive formats for the Job resource. You may specify multiple {\bf
1939 Job-overrides} on one {\bf Run} directive by separating them with one or
1940 more spaces or by separating them with a trailing comma. For example:
1946 \index[dir]{Directive!Level}
1947 is all files in the FileSet whether or not they have changed.
1949 \item [Level=Incremental]
1951 \index[dir]{Directive!Level}
1952 is all files that have changed since the last backup.
1956 \index[dir]{Directive!Pool}
1957 specifies to use the Pool named {\bf Weekly}.
1959 \item [Storage=DLT\_Drive]
1960 \index[dir]{Storage}
1961 \index[dir]{Directive!Storage}
1962 specifies to use {\bf DLT\_Drive} for the storage device.
1964 \item [Messages=Verbose]
1965 \index[dir]{Messages}
1966 \index[dir]{Directive!Messages}
1967 specifies to use the {\bf Verbose} message resource for the Job.
1969 \item [FullPool=Full]
1970 \index[dir]{FullPool}
1971 \index[dir]{Directive!FullPool}
1972 specifies to use the Pool named {\bf Full} if the job is a full backup, or
1974 upgraded from another type to a full backup.
1976 \item [DifferentialPool=Differential]
1977 \index[dir]{DifferentialPool}
1978 \index[dir]{Directive!DifferentialPool}
1979 specifies to use the Pool named {\bf Differential} if the job is a
1980 differential backup.
1982 \item [IncrementalPool=Incremental]
1983 \index[dir]{IncrementalPool}
1984 \index[dir]{Directive!IncrementalPool}
1985 specifies to use the Pool named {\bf Incremental} if the job is an
1988 \item [SpoolData=yes\vb{}no]
1989 \index[dir]{SpoolData}
1990 \index[dir]{Directive!SpoolData}
1991 tells Bacula to request the Storage daemon to spool data to a disk file
1992 before writing it to the Volume (normally a tape). Thus the data is
1993 written in large blocks to the Volume rather than small blocks. This
1994 directive is particularly useful when running multiple simultaneous
1995 backups to tape. It prevents interleaving of the job data and reduces
1996 or eliminates tape drive stop and start commonly known as "shoe-shine".
1998 \item [SpoolSize={\it bytes}]
1999 \index[dir]{SpoolSize}
2000 \index[dir]{Directive!SpoolSize}
2001 where the bytes specify the maximum spool size for this job.
2002 The default is take from Device Maximum Spool Size limit.
2003 This directive is available only in Bacula version 2.3.5 or
2006 \item [WritePartAfterJob=yes\vb{}no]
2007 \index[dir]{WritePartAfterJob}
2008 \index[dir]{Directive!WritePartAfterJob}
2009 tells Bacula to request the Storage daemon to write the current part
2010 file to the device when the job is finished (see \ilink{Write Part After
2011 Job directive in the Job resource}{WritePartAfterJob}). Please note,
2012 this directive is implemented only in version 1.37 and later. The
2013 default is yes. We strongly recommend that you keep this set to yes
2014 otherwise, when the last job has finished one part will remain in the
2015 spool file and restore may or may not work.
2019 {\bf Date-time-specification} determines when the Job is to be run. The
2020 specification is a repetition, and as a default Bacula is set to run a job at
2021 the beginning of the hour of every hour of every day of every week of every
2022 month of every year. This is not normally what you want, so you must specify
2023 or limit when you want the job to run. Any specification given is assumed to
2024 be repetitive in nature and will serve to override or limit the default
2025 repetition. This is done by specifying masks or times for the hour, day of the
2026 month, day of the week, week of the month, week of the year, and month when
2027 you want the job to run. By specifying one or more of the above, you can
2028 define a schedule to repeat at almost any frequency you want.
2030 Basically, you must supply a {\bf month}, {\bf day}, {\bf hour}, and {\bf
2031 minute} the Job is to be run. Of these four items to be specified, {\bf day}
2032 is special in that you may either specify a day of the month such as 1, 2,
2033 ... 31, or you may specify a day of the week such as Monday, Tuesday, ...
2034 Sunday. Finally, you may also specify a week qualifier to restrict the
2035 schedule to the first, second, third, fourth, or fifth week of the month.
2037 For example, if you specify only a day of the week, such as {\bf Tuesday} the
2038 Job will be run every hour of every Tuesday of every Month. That is the {\bf
2039 month} and {\bf hour} remain set to the defaults of every month and all
2042 Note, by default with no other specification, your job will run at the
2043 beginning of every hour. If you wish your job to run more than once in any
2044 given hour, you will need to specify multiple {\bf run} specifications each
2045 with a different minute.
2047 The date/time to run the Job can be specified in the following way in
2054 <week-keyword> = 1st | 2nd | 3rd | 4th | 5th | first |
2055 second | third | fourth | fifth
2056 <wday-keyword> = sun | mon | tue | wed | thu | fri | sat |
2057 sunday | monday | tuesday | wednesday |
2058 thursday | friday | saturday
2059 <week-of-year-keyword> = w00 | w01 | ... w52 | w53
2060 <month-keyword> = jan | feb | mar | apr | may | jun | jul |
2061 aug | sep | oct | nov | dec | january |
2062 february | ... | december
2063 <daily-keyword> = daily
2064 <weekly-keyword> = weekly
2065 <monthly-keyword> = monthly
2066 <hourly-keyword> = hourly
2067 <digit> = 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 0
2068 <number> = <digit> | <digit><number>
2069 <12hour> = 0 | 1 | 2 | ... 12
2070 <hour> = 0 | 1 | 2 | ... 23
2071 <minute> = 0 | 1 | 2 | ... 59
2072 <day> = 1 | 2 | ... 31
2073 <time> = <hour>:<minute> |
2074 <12hour>:<minute>am |
2076 <time-spec> = <at-keyword> <time> |
2078 <date-keyword> = <void-keyword> <weekly-keyword>
2079 <day-range> = <day>-<day>
2080 <month-range> = <month-keyword>-<month-keyword>
2081 <wday-range> = <wday-keyword>-<wday-keyword>
2082 <range> = <day-range> | <month-range> |
2084 <date> = <date-keyword> | <day> | <range>
2085 <date-spec> = <date> | <date-spec>
2086 <day-spec> = <day> | <wday-keyword> |
2087 <day> | <wday-range> |
2088 <week-keyword> <wday-keyword> |
2089 <week-keyword> <wday-range> |
2091 <month-spec> = <month-keyword> | <month-range> |
2093 <date-time-spec> = <month-spec> <day-spec> <time-spec>
2099 Note, the Week of Year specification wnn follows the ISO standard definition
2100 of the week of the year, where Week 1 is the week in which the first Thursday
2101 of the year occurs, or alternatively, the week which contains the 4th of
2102 January. Weeks are numbered w01 to w53. w00 for Bacula is the week that
2103 precedes the first ISO week (i.e. has the first few days of the year if any
2104 occur before Thursday). w00 is not defined by the ISO specification. A week
2105 starts with Monday and ends with Sunday.
2107 According to the NIST (US National Institute of Standards and Technology),
2108 12am and 12pm are ambiguous and can be defined to anything. However,
2109 12:01am is the same as 00:01 and 12:01pm is the same as 12:01, so Bacula
2110 defines 12am as 00:00 (midnight) and 12pm as 12:00 (noon). You can avoid
2111 this abiguity (confusion) by using 24 hour time specifications (i.e. no
2112 am/pm). This is the definition in Bacula version 2.0.3 and later.
2114 An example schedule resource that is named {\bf WeeklyCycle} and runs a job
2115 with level full each Sunday at 2:05am and an incremental job Monday through
2116 Saturday at 2:05am is:
2121 Name = "WeeklyCycle"
2122 Run = Level=Full sun at 2:05
2123 Run = Level=Incremental mon-sat at 2:05
2128 An example of a possible monthly cycle is as follows:
2133 Name = "MonthlyCycle"
2134 Run = Level=Full Pool=Monthly 1st sun at 2:05
2135 Run = Level=Differential 2nd-5th sun at 2:05
2136 Run = Level=Incremental Pool=Daily mon-sat at 2:05
2141 The first of every month:
2147 Run = Level=Full on 1 at 2:05
2148 Run = Level=Incremental on 2-31 at 2:05
2159 Run = Level=Full hourly at 0:05
2160 Run = Level=Full hourly at 0:15
2161 Run = Level=Full hourly at 0:25
2162 Run = Level=Full hourly at 0:35
2163 Run = Level=Full hourly at 0:45
2164 Run = Level=Full hourly at 0:55
2169 \section{Technical Notes on Schedules}
2170 \index[general]{Schedules!Technical Notes on}
2171 \index[general]{Technical Notes on Schedules}
2173 Internally Bacula keeps a schedule as a bit mask. There are six masks and a
2174 minute field to each schedule. The masks are hour, day of the month (mday),
2175 month, day of the week (wday), week of the month (wom), and week of the year
2176 (woy). The schedule is initialized to have the bits of each of these masks
2177 set, which means that at the beginning of every hour, the job will run. When
2178 you specify a month for the first time, the mask will be cleared and the bit
2179 corresponding to your selected month will be selected. If you specify a second
2180 month, the bit corresponding to it will also be added to the mask. Thus when
2181 Bacula checks the masks to see if the bits are set corresponding to the
2182 current time, your job will run only in the two months you have set. Likewise,
2183 if you set a time (hour), the hour mask will be cleared, and the hour you
2184 specify will be set in the bit mask and the minutes will be stored in the
2187 For any schedule you have defined, you can see how these bits are set by doing
2188 a {\bf show schedules} command in the Console program. Please note that the
2189 bit mask is zero based, and Sunday is the first day of the week (bit zero).
2193 \section{The Client Resource}
2194 \label{ClientResource2}
2195 \index[general]{Resource!Client}
2196 \index[general]{Client Resource}
2198 The Client resource defines the attributes of the Clients that are served by
2199 this Director; that is the machines that are to be backed up. You will need
2200 one Client resource definition for each machine to be backed up.
2204 \item [Client (or FileDaemon)]
2205 \index[dir]{Client (or FileDaemon)}
2206 \index[dir]{Directive!Client (or FileDaemon)}
2207 Start of the Client directives.
2209 \item [Name = \lt{}name\gt{}]
2211 \index[dir]{Directive!Name}
2212 The client name which will be used in the Job resource directive or in the
2213 console run command. This directive is required.
2215 \item [Address = \lt{}address\gt{}]
2216 \index[dir]{Address}
2217 \index[dir]{Directive!FD Address}
2218 \index[dir]{File Daemon Address}
2219 \index[dir]{Client Address}
2220 Where the address is a host name, a fully qualified domain name, or a
2221 network address in dotted quad notation for a Bacula File server daemon.
2222 This directive is required.
2224 \item [FD Port = \lt{}port-number\gt{}]
2225 \index[dir]{FD Port}
2226 \index[dir]{Directive!FD Port}
2227 Where the port is a port number at which the Bacula File server daemon can
2228 be contacted. The default is 9102.
2230 \item [Catalog = \lt{}Catalog-resource-name\gt{}]
2231 \index[dir]{Catalog}
2232 \index[dir]{Directive!Catalog}
2233 This specifies the name of the catalog resource to be used for this Client.
2234 This directive is required.
2236 \item [Password = \lt{}password\gt{}]
2237 \index[dir]{Password}
2238 \index[dir]{Directive!Password}
2239 This is the password to be used when establishing a connection with the File
2240 services, so the Client configuration file on the machine to be backed up
2241 must have the same password defined for this Director. This directive is
2242 required. If you have either {\bf /dev/random} {\bf bc} on your machine,
2243 Bacula will generate a random password during the configuration process,
2244 otherwise it will be left blank.
2246 The password is plain text. It is not generated through any special
2247 process, but it is preferable for security reasons to make the text
2250 \label{FileRetention}
2251 \item [File Retention = \lt{}time-period-specification\gt{}]
2252 \label{FileRetention}
2253 \index[dir]{File Retention}
2254 \index[dir]{Directive!File Retention}
2255 The File Retention directive defines the length of time that Bacula will
2256 keep File records in the Catalog database after the End time of the
2257 Job corresponding to the File records.
2258 When this time period expires, and if
2259 {\bf AutoPrune} is set to {\bf yes} Bacula will prune (remove) File records
2260 that are older than the specified File Retention period. Note, this affects
2261 only records in the catalog database. It does not affect your archive
2264 File records may actually be retained for a shorter period than you specify
2265 on this directive if you specify either a shorter {\bf Job Retention} or a
2266 shorter {\bf Volume Retention} period. The shortest retention period of the
2267 three takes precedence. The time may be expressed in seconds, minutes,
2268 hours, days, weeks, months, quarters, or years. See the
2269 \ilink{ Configuration chapter}{Time} of this manual for
2270 additional details of time specification.
2272 The default is 60 days.
2274 \label{JobRetention}
2275 \item [Job Retention = \lt{}time-period-specification\gt{}]
2276 \label{JobRetention}
2277 \index[dir]{Job Retention}
2278 \index[dir]{Directive!Job Retention}
2279 The Job Retention directive defines the length of time that Bacula will keep
2280 Job records in the Catalog database after the Job End time. When
2281 this time period expires, and if {\bf AutoPrune} is set to {\bf yes}
2282 Bacula will prune (remove) Job records that are older than the specified
2283 File Retention period. As with the other retention periods, this
2284 affects only records in the catalog and not data in your archive backup.
2286 If a Job record is selected for pruning, all associated File and JobMedia
2287 records will also be pruned regardless of the File Retention period set.
2288 As a consequence, you normally will set the File retention period to be
2289 less than the Job retention period. The Job retention period can actually
2290 be less than the value you specify here if you set the {\bf Volume
2291 Retention} directive in the Pool resource to a smaller duration. This is
2292 because the Job retention period and the Volume retention period are
2293 independently applied, so the smaller of the two takes precedence.
2295 The Job retention period is specified as seconds, minutes, hours, days,
2296 weeks, months, quarters, or years. See the
2297 \ilink{ Configuration chapter}{Time} of this manual for
2298 additional details of time specification.
2300 The default is 180 days.
2303 \item [AutoPrune = \lt{}yes\vb{}no\gt{}]
2304 \index[dir]{AutoPrune}
2305 \index[dir]{Directive!AutoPrune}
2306 If AutoPrune is set to {\bf yes} (default), Bacula (version 1.20 or greater)
2307 will automatically apply the File retention period and the Job retention
2308 period for the Client at the end of the Job. If you set {\bf AutoPrune = no},
2309 pruning will not be done, and your Catalog will grow in size each time you
2310 run a Job. Pruning affects only information in the catalog and not data
2311 stored in the backup archives (on Volumes).
2313 \item [Maximum Concurrent Jobs = \lt{}number\gt{}]
2314 \index[dir]{Maximum Concurrent Jobs}
2315 \index[dir]{Directive!Maximum Concurrent Jobs}
2316 where \lt{}number\gt{} is the maximum number of Jobs with the current Client
2317 that can run concurrently. Note, this directive limits only Jobs for Clients
2318 with the same name as the resource in which it appears. Any other
2319 restrictions on the maximum concurrent jobs such as in the Director, Job, or
2320 Storage resources will also apply in addition to any limit specified here.
2321 The default is set to 1, but you may set it to a larger number.
2323 \item [Priority = \lt{}number\gt{}]
2324 \index[dir]{Priority}
2325 \index[dir]{Directive!Priority}
2326 The number specifies the priority of this client relative to other clients
2327 that the Director is processing simultaneously. The priority can range from
2328 1 to 1000. The clients are ordered such that the smaller number priorities
2329 are performed first (not currently implemented).
2332 The following is an example of a valid Client resource definition:
2338 FDAddress = minimatou
2340 Password = very_good
2345 \section{The Storage Resource}
2346 \label{StorageResource2}
2347 \index[general]{Resource!Storage}
2348 \index[general]{Storage Resource}
2350 The Storage resource defines which Storage daemons are available for use by
2356 \index[dir]{Storage}
2357 \index[dir]{Directive!Storage}
2358 Start of the Storage resources. At least one storage resource must be
2361 \item [Name = \lt{}name\gt{}]
2363 \index[dir]{Directive!Name}
2364 The name of the storage resource. This name appears on the Storage directive
2365 specified in the Job resource and is required.
2367 \item [Address = \lt{}address\gt{}]
2368 \index[dir]{Address}
2369 \index[dir]{Directive!SD Address}
2370 \index[dir]{Storage daemon Address}
2371 Where the address is a host name, a {\bf fully qualified domain name}, or an
2372 {\bf IP address}. Please note that the \lt{}address\gt{} as specified here
2373 will be transmitted to the File daemon who will then use it to contact the
2374 Storage daemon. Hence, it is {\bf not}, a good idea to use {\bf localhost} as
2375 the name but rather a fully qualified machine name or an IP address. This
2376 directive is required.
2378 \item [SD Port = \lt{}port\gt{}]
2379 \index[dir]{SD Port}
2380 \index[dir]{Directive!SD Port}
2381 Where port is the port to use to contact the storage daemon for information
2382 and to start jobs. This same port number must appear in the Storage resource
2383 of the Storage daemon's configuration file. The default is 9103.
2385 \item [Password = \lt{}password\gt{}]
2386 \index[dir]{Password}
2387 \index[dir]{Directive!Password}
2388 This is the password to be used when establishing a connection with the
2389 Storage services. This same password also must appear in the Director
2390 resource of the Storage daemon's configuration file. This directive is
2391 required. If you have either {\bf /dev/random} {\bf bc} on your machine,
2392 Bacula will generate a random password during the configuration process,
2393 otherwise it will be left blank.
2395 The password is plain text. It is not generated through any special
2396 process, but it is preferable for security reasons to use random text.
2398 \item [Device = \lt{}device-name\gt{}]
2400 \index[dir]{Directive!Device}
2401 This directive specifies the Storage daemon's name of the device
2402 resource to be used for the storage. If you are using an Autochanger,
2403 the name specified here should be the name of the Storage daemon's
2404 Autochanger resource rather than the name of an individual device. This
2405 name is not the physical device name, but the logical device name as
2406 defined on the {\bf Name} directive contained in the {\bf Device} or the
2407 {\bf Autochanger} resource definition of the {\bf Storage daemon}
2408 configuration file. You can specify any name you would like (even the
2409 device name if you prefer) up to a maximum of 127 characters in length.
2410 The physical device name associated with this device is specified in the
2411 {\bf Storage daemon} configuration file (as {\bf Archive Device}).
2412 Please take care not to define two different Storage resource directives
2413 in the Director that point to the same Device in the Storage daemon.
2414 Doing so may cause the Storage daemon to block (or hang) attempting to
2415 open the same device that is already open. This directive is required.
2418 \item [Media Type = \lt{}MediaType\gt{}]
2419 \index[dir]{Media Type}
2420 \index[dir]{Directive!Media Type}
2421 This directive specifies the Media Type to be used to store the data.
2422 This is an arbitrary string of characters up to 127 maximum that you
2423 define. It can be anything you want. However, it is best to make it
2424 descriptive of the storage media (e.g. File, DAT, "HP DLT8000", 8mm,
2425 ...). In addition, it is essential that you make the {\bf Media Type}
2426 specification unique for each storage media type. If you have two DDS-4
2427 drives that have incompatible formats, or if you have a DDS-4 drive and
2428 a DDS-4 autochanger, you almost certainly should specify different {\bf
2429 Media Types}. During a restore, assuming a {\bf DDS-4} Media Type is
2430 associated with the Job, Bacula can decide to use any Storage daemon
2431 that supports Media Type {\bf DDS-4} and on any drive that supports it.
2433 If you are writing to disk Volumes, you must make doubly sure that each
2434 Device resource defined in the Storage daemon (and hence in the
2435 Director's conf file) has a unique media type. Otherwise for Bacula
2436 versions 1.38 and older, your restores may not work because Bacula
2437 will assume that you can mount any Media Type with the same name on
2438 any Device associated with that Media Type. This is possible with
2439 tape drives, but with disk drives, unless you are very clever you
2440 cannot mount a Volume in any directory -- this can be done by creating
2441 an appropriate soft link.
2443 Currently Bacula permits only a single Media Type per Storage
2444 and Device definition. Consequently, if
2445 you have a drive that supports more than one Media Type, you can
2446 give a unique string to Volumes with different intrinsic Media
2447 Type (Media Type = DDS-3-4 for DDS-3 and DDS-4 types), but then
2448 those volumes will only be mounted on drives indicated with the
2449 dual type (DDS-3-4).
2451 If you want to tie Bacula to using a single Storage daemon or drive, you
2452 must specify a unique Media Type for that drive. This is an important
2453 point that should be carefully understood. Note, this applies equally
2454 to Disk Volumes. If you define more than one disk Device resource in
2455 your Storage daemon's conf file, the Volumes on those two devices are in
2456 fact incompatible because one can not be mounted on the other device
2457 since they are found in different directories. For this reason, you
2458 probably should use two different Media Types for your two disk Devices
2459 (even though you might think of them as both being File types). You can
2460 find more on this subject in the \ilink{Basic Volume
2461 Management}{DiskChapter} chapter of this manual.
2463 The {\bf MediaType} specified in the Director's Storage resource, {\bf
2464 must} correspond to the {\bf Media Type} specified in the {\bf Device}
2465 resource of the {\bf Storage daemon} configuration file. This directive
2466 is required, and it is used by the Director and the Storage daemon to
2467 ensure that a Volume automatically selected from the Pool corresponds to
2468 the physical device. If a Storage daemon handles multiple devices (e.g.
2469 will write to various file Volumes on different partitions), this
2470 directive allows you to specify exactly which device.
2472 As mentioned above, the value specified in the Director's Storage
2473 resource must agree with the value specified in the Device resource in
2474 the {\bf Storage daemon's} configuration file. It is also an additional
2475 check so that you don't try to write data for a DLT onto an 8mm device.
2477 \label{Autochanger1}
2478 \item [Autochanger = \lt{}yes\vb{}no\gt{}]
2479 \index[dir]{Autochanger}
2480 \index[dir]{Directive!Autochanger}
2481 If you specify {\bf yes} for this command (the default is {\bf no}),
2482 when you use the {\bf label} command or the {\bf add} command to create
2483 a new Volume, {\bf Bacula} will also request the Autochanger Slot
2484 number. This simplifies creating database entries for Volumes in an
2485 autochanger. If you forget to specify the Slot, the autochanger will
2486 not be used. However, you may modify the Slot associated with a Volume
2487 at any time by using the {\bf update volume} or {\bf update slots}
2488 command in the console program. When {\bf autochanger} is enabled, the
2489 algorithm used by Bacula to search for available volumes will be
2490 modified to consider only Volumes that are known to be in the
2491 autochanger's magazine. If no {\bf in changer} volume is found, Bacula
2492 will attempt recycling, pruning, ..., and if still no volume is found,
2493 Bacula will search for any volume whether or not in the magazine. By
2494 privileging in changer volumes, this procedure minimizes operator
2495 intervention. The default is {\bf no}.
2497 For the autochanger to be used, you must also specify {\bf Autochanger =
2498 yes} in the \ilink{Device Resource}{Autochanger} in the Storage daemon's
2499 configuration file as well as other important Storage daemon
2500 configuration information. Please consult the \ilink{Using
2501 Autochangers}{AutochangersChapter} manual of this chapter for the
2502 details of using autochangers.
2504 \item [Maximum Concurrent Jobs = \lt{}number\gt{}]
2505 \index[dir]{Maximum Concurrent Jobs}
2506 \index[dir]{Directive!Maximum Concurrent Jobs}
2507 where \lt{}number\gt{} is the maximum number of Jobs with the current
2508 Storage resource that can run concurrently. Note, this directive limits
2509 only Jobs for Jobs using this Storage daemon. Any other restrictions on
2510 the maximum concurrent jobs such as in the Director, Job, or Client
2511 resources will also apply in addition to any limit specified here. The
2512 default is set to 1, but you may set it to a larger number. However, if
2513 you set the Storage daemon's number of concurrent jobs greater than one,
2514 we recommend that you read the waring documented under \ilink{Maximum
2515 Concurrent Jobs}{DirMaxConJobs} in the Director's resource or simply
2516 turn data spooling on as documented in the \ilink{Data
2517 Spooling}{SpoolingChapter} chapter of this manual.
2519 \item [AllowCompression = \lt{}yes\vb{}no\gt{}]
2520 \label{AllowCompression}
2521 \index[dir]{AllowCompression}
2522 \index[dir]{Directive!AllowCompression}
2524 This directive is optional, and if you specify {\bf No} (the default is {\bf
2525 Yes}), it will cause backups jobs running on this storage resource to run
2526 without client File Daemon compression. This effectively overrides
2527 compression options in FileSets used by jobs which use this storage
2530 \item [Heartbeat Interval = \lt{}time-interval\gt{}]
2531 \index[dir]{Heartbeat Interval}
2532 \index[dir]{Directive!Heartbeat}
2533 This directive is optional and if specified will cause the Director to
2534 set a keepalive interval (heartbeat) in seconds on each of the sockets
2535 it opens for the Storage resource. This value will override any
2536 specified at the Director level. It is implemented only on systems
2537 (Linux, ...) that provide the {\bf setsockopt} TCP\_KEEPIDLE function.
2538 The default value is zero, which means no change is made to the socket.
2542 The following is an example of a valid Storage resource definition:
2546 # Definition of tape storage device
2550 Password = storage_password # password for Storage daemon
2551 Device = "HP DLT 80" # same as Device in Storage daemon
2552 Media Type = DLT8000 # same as MediaType in Storage daemon
2557 \section{The Pool Resource}
2558 \label{PoolResource}
2559 \index[general]{Resource!Pool}
2560 \index[general]{Pool Resource}
2562 The Pool resource defines the set of storage Volumes (tapes or files) to be
2563 used by Bacula to write the data. By configuring different Pools, you can
2564 determine which set of Volumes (media) receives the backup data. This permits,
2565 for example, to store all full backup data on one set of Volumes and all
2566 incremental backups on another set of Volumes. Alternatively, you could assign
2567 a different set of Volumes to each machine that you backup. This is most
2568 easily done by defining multiple Pools.
2570 Another important aspect of a Pool is that it contains the default attributes
2571 (Maximum Jobs, Retention Period, Recycle flag, ...) that will be given to a
2572 Volume when it is created. This avoids the need for you to answer a large
2573 number of questions when labeling a new Volume. Each of these attributes can
2574 later be changed on a Volume by Volume basis using the {\bf update} command in
2575 the console program. Note that you must explicitly specify which Pool Bacula
2576 is to use with each Job. Bacula will not automatically search for the correct
2579 Most often in Bacula installations all backups for all machines (Clients) go
2580 to a single set of Volumes. In this case, you will probably only use the {\bf
2581 Default} Pool. If your backup strategy calls for you to mount a different tape
2582 each day, you will probably want to define a separate Pool for each day. For
2583 more information on this subject, please see the
2584 \ilink{Backup Strategies}{StrategiesChapter} chapter of this
2588 To use a Pool, there are three distinct steps. First the Pool must be defined
2589 in the Director's configuration file. Then the Pool must be written to the
2590 Catalog database. This is done automatically by the Director each time that it
2591 starts, or alternatively can be done using the {\bf create} command in the
2592 console program. Finally, if you change the Pool definition in the Director's
2593 configuration file and restart Bacula, the pool will be updated alternatively
2594 you can use the {\bf update pool} console command to refresh the database
2595 image. It is this database image rather than the Director's resource image
2596 that is used for the default Volume attributes. Note, for the pool to be
2597 automatically created or updated, it must be explicitly referenced by a Job
2600 Next the physical media must be labeled. The labeling can either be done with
2601 the {\bf label} command in the {\bf console} program or using the {\bf btape}
2602 program. The preferred method is to use the {\bf label} command in the {\bf
2605 Finally, you must add Volume names (and their attributes) to the Pool. For
2606 Volumes to be used by Bacula they must be of the same {\bf Media Type} as the
2607 archive device specified for the job (i.e. if you are going to back up to a
2608 DLT device, the Pool must have DLT volumes defined since 8mm volumes cannot be
2609 mounted on a DLT drive). The {\bf Media Type} has particular importance if you
2610 are backing up to files. When running a Job, you must explicitly specify which
2611 Pool to use. Bacula will then automatically select the next Volume to use from
2612 the Pool, but it will ensure that the {\bf Media Type} of any Volume selected
2613 from the Pool is identical to that required by the Storage resource you have
2614 specified for the Job.
2616 If you use the {\bf label} command in the console program to label the
2617 Volumes, they will automatically be added to the Pool, so this last step is
2618 not normally required.
2620 It is also possible to add Volumes to the database without explicitly labeling
2621 the physical volume. This is done with the {\bf add} console command.
2623 As previously mentioned, each time Bacula starts, it scans all the Pools
2624 associated with each Catalog, and if the database record does not already
2625 exist, it will be created from the Pool Resource definition. {\bf Bacula}
2626 probably should do an {\bf update pool} if you change the Pool definition, but
2627 currently, you must do this manually using the {\bf update pool} command in
2628 the Console program.
2630 The Pool Resource defined in the Director's configuration file
2631 (bacula-dir.conf) may contain the following directives:
2637 \index[dir]{Directive!Pool}
2638 Start of the Pool resource. There must be at least one Pool resource
2642 \item [Name = \lt{}name\gt{}]
2644 \index[dir]{Directive!Name}
2645 The name of the pool. For most applications, you will use the default
2646 pool name {\bf Default}. This directive is required.
2649 \item [Maximum Volumes = \lt{}number\gt{}]
2650 \index[dir]{Maximum Volumes}
2651 \index[dir]{Directive!Maximum Volumes}
2652 This directive specifies the maximum number of volumes (tapes or files)
2653 contained in the pool. This directive is optional, if omitted or set to
2654 zero, any number of volumes will be permitted. In general, this
2655 directive is useful for Autochangers where there is a fixed number of
2656 Volumes, or for File storage where you wish to ensure that the backups
2657 made to disk files do not become too numerous or consume too much space.
2659 \item [Pool Type = \lt{}type\gt{}]
2660 \index[dir]{Pool Type}
2661 \index[dir]{Directive!Pool Type}
2662 This directive defines the pool type, which corresponds to the type of
2663 Job being run. It is required and may be one of the following:
2673 Note, only Backup is current implemented.
2675 \item [Storage = \lt{}storage-resource-name\gt{}]
2676 \index[dir]{Storage}
2677 \index[dir]{Directive!Storage}
2678 The Storage directive defines the name of the storage services where you
2679 want to backup the FileSet data. For additional details, see the
2680 \ilink{Storage Resource Chapter}{StorageResource2} of this manual.
2681 The Storage resource may also be specified in the Job resource,
2682 but the value, if any, in the Pool resource overrides any value
2683 in the Job. This Storage resource definition is not required by either
2684 the Job resource or in the Pool, but it must be specified in
2685 one or the other. If not configuration error will result.
2687 \item [Use Volume Once = \lt{}yes\vb{}no\gt{}]
2688 \index[dir]{Use Volume Once}
2689 \index[dir]{Directive!Use Volume Once}
2690 This directive if set to {\bf yes} specifies that each volume is to be
2691 used only once. This is most useful when the Media is a file and you
2692 want a new file for each backup that is done. The default is {\bf no}
2693 (i.e. use volume any number of times). This directive will most likely
2694 be phased out (deprecated), so you are recommended to use {\bf Maximum
2695 Volume Jobs = 1} instead.
2697 The value defined by this directive in the bacula-dir.conf file is the
2698 default value used when a Volume is created. Once the volume is
2699 created, changing the value in the bacula-dir.conf file will not change
2700 what is stored for the Volume. To change the value for an existing
2701 Volume you must use the {\bf update} command in the Console.
2703 Please see the notes below under {\bf Maximum Volume Jobs} concerning
2704 using this directive with multiple simultaneous jobs.
2706 \item [Maximum Volume Jobs = \lt{}positive-integer\gt{}]
2707 \index[dir]{Maximum Volume Jobs}
2708 \index[dir]{Directive!Maximum Volume Jobs}
2709 This directive specifies the maximum number of Jobs that can be written
2710 to the Volume. If you specify zero (the default), there is no limit.
2711 Otherwise, when the number of Jobs backed up to the Volume equals {\bf
2712 positive-integer} the Volume will be marked {\bf Used}. When the Volume
2713 is marked {\bf Used} it can no longer be used for appending Jobs, much
2714 like the {\bf Full} status but it can be recycled if recycling is
2715 enabled, and thus used again. By setting {\bf MaximumVolumeJobs} to
2716 one, you get the same effect as setting {\bf UseVolumeOnce = yes}.
2718 The value defined by this directive in the bacula-dir.conf
2719 file is the default value used when a Volume is created. Once the volume is
2720 created, changing the value in the bacula-dir.conf file will not change what
2721 is stored for the Volume. To change the value for an existing Volume you
2722 must use the {\bf update} command in the Console.
2724 If you are running multiple simultaneous jobs, this directive may not
2725 work correctly because when a drive is reserved for a job, this
2726 directive is not taken into account, so multiple jobs may try to
2727 start writing to the Volume. At some point, when the Media record is
2728 updated, multiple simultaneous jobs may fail since the Volume can no
2731 \item [Maximum Volume Files = \lt{}positive-integer\gt{}]
2732 \index[dir]{Maximum Volume Files}
2733 \index[dir]{Directive!Maximum Volume Files}
2734 This directive specifies the maximum number of files that can be written
2735 to the Volume. If you specify zero (the default), there is no limit.
2736 Otherwise, when the number of files written to the Volume equals {\bf
2737 positive-integer} the Volume will be marked {\bf Used}. When the Volume
2738 is marked {\bf Used} it can no longer be used for appending Jobs, much
2739 like the {\bf Full} status but it can be recycled if recycling is
2740 enabled and thus used again. This value is checked and the {\bf Used}
2741 status is set only at the end of a job that writes to the particular
2744 The value defined by this directive in the bacula-dir.conf file is the
2745 default value used when a Volume is created. Once the volume is
2746 created, changing the value in the bacula-dir.conf file will not change
2747 what is stored for the Volume. To change the value for an existing
2748 Volume you must use the {\bf update} command in the Console.
2750 \item [Maximum Volume Bytes = \lt{}size\gt{}]
2751 \index[dir]{Maximum Volume Bytes}
2752 \index[dir]{Directive!Maximum Volume Bytes}
2753 This directive specifies the maximum number of bytes that can be written
2754 to the Volume. If you specify zero (the default), there is no limit
2755 except the physical size of the Volume. Otherwise, when the number of
2756 bytes written to the Volume equals {\bf size} the Volume will be marked
2757 {\bf Used}. When the Volume is marked {\bf Used} it can no longer be
2758 used for appending Jobs, much like the {\bf Full} status but it can be
2759 recycled if recycling is enabled, and thus the Volume can be re-used
2760 after recycling. This value is checked and the {\bf Used} status set
2761 while the job is writing to the particular volume.
2763 This directive is particularly useful for restricting the size
2764 of disk volumes, and will work correctly even in the case of
2765 multiple simultaneous jobs writing to the volume.
2767 The value defined by this directive in the bacula-dir.conf file is the
2768 default value used when a Volume is created. Once the volume is
2769 created, changing the value in the bacula-dir.conf file will not change
2770 what is stored for the Volume. To change the value for an existing
2771 Volume you must use the {\bf update} command in the Console.
2773 \item [Volume Use Duration = \lt{}time-period-specification\gt{}]
2774 \index[dir]{Volume Use Duration}
2775 \index[dir]{Directive!Volume Use Duration}
2776 The Volume Use Duration directive defines the time period that the
2777 Volume can be written beginning from the time of first data write to the
2778 Volume. If the time-period specified is zero (the default), the Volume
2779 can be written indefinitely. Otherwise, the next time a job
2780 runs that wants to access this Volume, and the time period from the
2781 first write to the volume (the first Job written) exceeds the
2782 time-period-specification, the Volume will be marked {\bf Used}, which
2783 means that no more Jobs can be appended to the Volume, but it may be
2784 recycled if recycling is enabled. Using the command {\bf
2785 status dir} applies algorithms similar to running jobs, so
2786 during such a command, the Volume status may also be changed.
2788 recycled, it will be available for use again.
2790 You might use this directive, for example, if you have a Volume used for
2791 Incremental backups, and Volumes used for Weekly Full backups. Once the
2792 Full backup is done, you will want to use a different Incremental
2793 Volume. This can be accomplished by setting the Volume Use Duration for
2794 the Incremental Volume to six days. I.e. it will be used for the 6
2795 days following a Full save, then a different Incremental volume will be
2796 used. Be careful about setting the duration to short periods such as 23
2797 hours, or you might experience problems of Bacula waiting for a tape
2798 over the weekend only to complete the backups Monday morning when an
2799 operator mounts a new tape.
2801 The use duration is checked and the {\bf Used} status is set only at the
2802 end of a job that writes to the particular volume, which means that even
2803 though the use duration may have expired, the catalog entry will not be
2804 updated until the next job that uses this volume is run. This
2805 directive is not intended to be used to limit volume sizes
2806 and will not work correctly (i.e. will fail jobs) if the use
2807 duration expires while multiple simultaneous jobs are writing
2810 Please note that the value defined by this directive in the bacula-dir.conf
2811 file is the default value used when a Volume is created. Once the volume is
2812 created, changing the value in the bacula-dir.conf file will not change what
2813 is stored for the Volume. To change the value for an existing Volume you
2815 \ilink{\bf update volume}{UpdateCommand} command in the Console.
2817 \item [Catalog Files = \lt{}yes\vb{}no\gt{}]
2818 \index[dir]{Catalog Files}
2819 \index[dir]{Directive!Catalog Files}
2820 This directive defines whether or not you want the names of the files
2821 that were saved to be put into the catalog. The default is {\bf yes}.
2822 The advantage of specifying {\bf Catalog Files = No} is that you will
2823 have a significantly smaller Catalog database. The disadvantage is that
2824 you will not be able to produce a Catalog listing of the files backed up
2825 for each Job (this is often called Browsing). Also, without the File
2826 entries in the catalog, you will not be able to use the Console {\bf
2827 restore} command nor any other command that references File entries.
2829 \label{PoolAutoPrune}
2830 \item [AutoPrune = \lt{}yes\vb{}no\gt{}]
2831 \index[dir]{AutoPrune}
2832 \index[dir]{Directive!AutoPrune}
2833 If AutoPrune is set to {\bf yes} (default), Bacula (version 1.20 or
2834 greater) will automatically apply the Volume Retention period when new
2835 Volume is needed and no appendable Volumes exist in the Pool. Volume
2836 pruning causes expired Jobs (older than the {\bf Volume Retention}
2837 period) to be deleted from the Catalog and permits possible recycling of
2840 \label{VolRetention}
2841 \item [Volume Retention = \lt{}time-period-specification\gt{}]
2842 \index[dir]{Volume Retention}
2843 \index[dir]{Directive!Volume Retention}
2844 The Volume Retention directive defines the length of time that {\bf
2845 Bacula} will keep records associated with the Volume in
2846 the Catalog database after the End time of each Job written to the
2847 Volume. When this time period expires, and if {\bf AutoPrune} is set to
2848 {\bf yes} Bacula may prune (remove) Job records that are older than the
2849 specified Volume Retention period if it is necessary to free up a
2850 Volume. Recycling will not occur until it is absolutely necessary to
2851 free up a volume (i.e. no other writable volume exists).
2852 All File records associated with pruned Jobs are also
2853 pruned. The time may be specified as seconds, minutes, hours, days,
2854 weeks, months, quarters, or years. The {\bf Volume Retention} is
2855 applied independently of the {\bf Job Retention} and the {\bf File
2856 Retention} periods defined in the Client resource. This means that all
2857 the retentions periods are applied in turn and that the shorter period
2858 is the one that effectively takes precedence. Note, that when the {\bf
2859 Volume Retention} period has been reached, and it is necessary to obtain
2860 a new volume, Bacula will prune both the Job and the File records. This
2861 pruning could also occur during a {\bf status dir} command because it
2862 uses similar algorithms for finding the next available Volume.
2864 It is important to know that when the Volume Retention period expires,
2865 Bacula does not automatically recycle a Volume. It attempts to keep the
2866 Volume data intact as long as possible before over writing the Volume.
2868 By defining multiple Pools with different Volume Retention periods, you
2869 may effectively have a set of tapes that is recycled weekly, another
2870 Pool of tapes that is recycled monthly and so on. However, one must
2871 keep in mind that if your {\bf Volume Retention} period is too short, it
2872 may prune the last valid Full backup, and hence until the next Full
2873 backup is done, you will not have a complete backup of your system, and
2874 in addition, the next Incremental or Differential backup will be
2875 promoted to a Full backup. As a consequence, the minimum {\bf Volume
2876 Retention} period should be at twice the interval of your Full backups.
2877 This means that if you do a Full backup once a month, the minimum Volume
2878 retention period should be two months.
2880 The default Volume retention period is 365 days, and either the default
2881 or the value defined by this directive in the bacula-dir.conf file is
2882 the default value used when a Volume is created. Once the volume is
2883 created, changing the value in the bacula-dir.conf file will not change
2884 what is stored for the Volume. To change the value for an existing
2885 Volume you must use the {\bf update} command in the Console.
2887 \item [Action On Purge = \lt{Truncate}]
2888 \index[dir]{actiononpurge}
2890 This directive \textbf{ActionOnPurge=Truncate} instructs Bacula to truncate the
2891 volume when it is purged with the \texttt{purge volume action=truncate}
2892 command. It is useful to prevent disk based volumes from consuming too much
2898 Action On Purge = Truncate
2903 You can schedule the truncate operation at the end of your CatalogBackup job
2904 like in this example:
2908 Name = CatalogBackup
2913 Console = "purge volume action=all allpools storage=File"
2918 \label{PoolScratchPool}
2919 \item [ScratchPool = \lt{}pool-resource-name\gt{}]
2920 \index[dir]{ScrachPool}
2921 \index[dir]{Directive!ScrachPool}
2922 This directive permits to specify a dedicate \textsl{Scratch} for the
2923 current pool. This pool will replace the special pool named \textsl{Scrach}
2924 for volume selection. For more information about \textsl{Scratch} see
2925 \ilink{Scratch Pool}{TheScratchPool} section of this manual. This is useful
2926 when using multiple storage sharing the same mediatype or when you want to
2927 dedicate volumes to a particular set of pool.
2929 \label{PoolRecyclePool}
2930 \item [RecyclePool = \lt{}pool-resource-name\gt{}]
2931 \index[dir]{RecyclePool}
2932 \index[dir]{Directive!RecyclePool}
2933 This directive defines to which pool
2934 the Volume will be placed (moved) when it is recycled. Without
2935 this directive, a Volume will remain in the same pool when it is
2936 recycled. With this directive, it can be moved automatically to any
2937 existing pool during a recycle. This directive is probably most
2938 useful when defined in the Scratch pool, so that volumes will
2939 be recycled back into the Scratch pool. For more on the see the
2940 \ilink{Scratch Pool}{TheScratchPool} section of this manual.
2942 Although this directive is called RecyclePool, the Volume in
2943 question is actually moved from its current pool to the one
2944 you specify on this directive when Bacula prunes the Volume and
2945 discovers that there are no records left in the catalog and hence
2946 marks it as {\bf Purged}.
2950 \item [Recycle = \lt{}yes\vb{}no\gt{}]
2951 \index[dir]{Recycle}
2952 \index[dir]{Directive!Recycle}
2953 This directive specifies whether or not Purged Volumes may be recycled.
2954 If it is set to {\bf yes} (default) and Bacula needs a volume but finds
2955 none that are appendable, it will search for and recycle (reuse) Purged
2956 Volumes (i.e. volumes with all the Jobs and Files expired and thus
2957 deleted from the Catalog). If the Volume is recycled, all previous data
2958 written to that Volume will be overwritten. If Recycle is set to {\bf
2959 no}, the Volume will not be recycled, and hence, the data will remain
2960 valid. If you want to reuse (re-write) the Volume, and the recycle flag
2961 is no (0 in the catalog), you may manually set the recycle flag (update
2962 command) for a Volume to be reused.
2964 Please note that the value defined by this directive in the
2965 bacula-dir.conf file is the default value used when a Volume is created.
2966 Once the volume is created, changing the value in the bacula-dir.conf
2967 file will not change what is stored for the Volume. To change the value
2968 for an existing Volume you must use the {\bf update} command in the
2971 When all Job and File records have been pruned or purged from the
2972 catalog for a particular Volume, if that Volume is marked as
2973 Append, Full, Used, or Error, it will then be marked as Purged. Only
2974 Volumes marked as Purged will be considered to be converted to the
2975 Recycled state if the {\bf Recycle} directive is set to {\bf yes}.
2978 \label{RecycleOldest}
2979 \item [Recycle Oldest Volume = \lt{}yes\vb{}no\gt{}]
2980 \index[dir]{Recycle Oldest Volume}
2981 \index[dir]{Directive!Recycle Oldest Volume}
2982 This directive instructs the Director to search for the oldest used
2983 Volume in the Pool when another Volume is requested by the Storage
2984 daemon and none are available. The catalog is then {\bf pruned}
2985 respecting the retention periods of all Files and Jobs written to this
2986 Volume. If all Jobs are pruned (i.e. the volume is Purged), then the
2987 Volume is recycled and will be used as the next Volume to be written.
2988 This directive respects any Job, File, or Volume retention periods that
2989 you may have specified, and as such it is {\bf much} better to use this
2990 directive than the Purge Oldest Volume.
2992 This directive can be useful if you have a fixed number of Volumes in the
2993 Pool and you want to cycle through them and you have specified the correct
2996 However, if you use this directive and have only one
2997 Volume in the Pool, you will immediately recycle your Volume if you fill
2998 it and Bacula needs another one. Thus your backup will be totally invalid.
2999 Please use this directive with care. The default is {\bf no}.
3001 \label{RecycleCurrent}
3003 \item [Recycle Current Volume = \lt{}yes\vb{}no\gt{}]
3004 \index[dir]{Recycle Current Volume}
3005 \index[dir]{Directive!Recycle Current Volume}
3006 If Bacula needs a new Volume, this directive instructs Bacula to Prune
3007 the volume respecting the Job and File retention periods. If all Jobs
3008 are pruned (i.e. the volume is Purged), then the Volume is recycled and
3009 will be used as the next Volume to be written. This directive respects
3010 any Job, File, or Volume retention periods that you may have specified,
3011 and thus it is {\bf much} better to use it rather than the Purge Oldest
3014 This directive can be useful if you have: a fixed number of Volumes in
3015 the Pool, you want to cycle through them, and you have specified
3016 retention periods that prune Volumes before you have cycled through the
3019 However, if you use this directive and have only one Volume in the Pool,
3020 you will immediately recycle your Volume if you fill it and Bacula needs
3021 another one. Thus your backup will be totally invalid. Please use this
3022 directive with care. The default is {\bf no}.
3026 \item [Purge Oldest Volume = \lt{}yes\vb{}no\gt{}]
3027 \index[dir]{Purge Oldest Volume}
3028 \index[dir]{Directive!Purge Oldest Volume}
3029 This directive instructs the Director to search for the oldest used
3030 Volume in the Pool when another Volume is requested by the Storage
3031 daemon and none are available. The catalog is then {\bf purged}
3032 irrespective of retention periods of all Files and Jobs written to this
3033 Volume. The Volume is then recycled and will be used as the next Volume
3034 to be written. This directive overrides any Job, File, or Volume
3035 retention periods that you may have specified.
3037 This directive can be useful if you have a fixed number of Volumes in
3038 the Pool and you want to cycle through them and reusing the oldest one
3039 when all Volumes are full, but you don't want to worry about setting
3040 proper retention periods. However, by using this option you risk losing
3043 Please be aware that {\bf Purge Oldest Volume} disregards all retention
3044 periods. If you have only a single Volume defined and you turn this
3045 variable on, that Volume will always be immediately overwritten when it
3046 fills! So at a minimum, ensure that you have a decent number of Volumes
3047 in your Pool before running any jobs. If you want retention periods to
3048 apply do not use this directive. To specify a retention period, use the
3049 {\bf Volume Retention} directive (see above).
3051 We {\bf highly} recommend against using this directive, because it is
3052 sure that some day, Bacula will recycle a Volume that contains current
3053 data. The default is {\bf no}.
3055 \item [File Retention = \lt{}time-period-specification\gt{}]
3056 \index[dir]{File Retention}
3057 \index[dir]{Directive!File Retention}
3058 The File Retention directive defines the length of time that Bacula will
3059 keep File records in the Catalog database after the End time of the
3060 Job corresponding to the File records.
3062 This directive takes precedence over Client directives of the same name. For
3063 example, you can decide to increase Retention times for Archive or OffSite
3066 Note, this affects only records in the catalog database. It does not affect
3067 your archive backups.
3069 For more information see Client documentation about
3070 \ilink{FileRetention}{FileRetention}
3072 \item [Job Retention = \lt{}time-period-specification\gt{}]
3073 \index[dir]{Job Retention}
3074 \index[dir]{Directive!Job Retention}
3076 The Job Retention directive defines the length of time that Bacula will keep
3077 Job records in the Catalog database after the Job End time. As with the
3078 other retention periods, this affects only records in the catalog and not
3079 data in your archive backup.
3081 This directive takes precedence over Client directives of the same name.
3082 For example, you can decide to increase Retention times for Archive or
3085 For more information see Client side documentation
3086 \ilink{JobRetention}{JobRetention}
3088 \item [Cleaning Prefix = \lt{}string\gt{}]
3089 \index[dir]{Cleaning Prefix}
3090 \index[dir]{Directive!Cleaning Prefix}
3091 This directive defines a prefix string, which if it matches the
3092 beginning of a Volume name during labeling of a Volume, the Volume will
3093 be defined with the VolStatus set to {\bf Cleaning} and thus Bacula will
3094 never attempt to use this tape. This is primarily for use with
3095 autochangers that accept barcodes where the convention is that barcodes
3096 beginning with {\bf CLN} are treated as cleaning tapes.
3099 \item [Label Format = \lt{}format\gt{}]
3100 \index[dir]{Label Format}
3101 \index[dir]{Directive!Label Format}
3102 This directive specifies the format of the labels contained in this
3103 pool. The format directive is used as a sort of template to create new
3104 Volume names during automatic Volume labeling.
3106 The {\bf format} should be specified in double quotes, and consists of
3107 letters, numbers and the special characters hyphen ({\bf -}), underscore
3108 ({\bf \_}), colon ({\bf :}), and period ({\bf .}), which are the legal
3109 characters for a Volume name. The {\bf format} should be enclosed in
3112 In addition, the format may contain a number of variable expansion
3113 characters which will be expanded by a complex algorithm allowing you to
3114 create Volume names of many different formats. In all cases, the
3115 expansion process must resolve to the set of characters noted above that
3116 are legal Volume names. Generally, these variable expansion characters
3117 begin with a dollar sign ({\bf \$}) or a left bracket ({\bf [}). If you
3118 specify variable expansion characters, you should always enclose the
3119 format with double quote characters ({\bf "}). For more details on
3120 variable expansion, please see the \ilink{Variable
3121 Expansion}{VarsChapter} Chapter of this manual.
3123 If no variable expansion characters are found in the string, the Volume
3124 name will be formed from the {\bf format} string appended with the
3125 a unique number that increases. If you do not remove volumes from the
3126 pool, this number should be the number of volumes plus one, but this
3127 is not guaranteed. The unique number will be edited as four
3128 digits with leading zeros. For example, with a {\bf Label Format =
3129 "File-"}, the first volumes will be named {\bf File-0001}, {\bf
3132 With the exception of Job specific variables, you can test your {\bf
3133 LabelFormat} by using the \ilink{ var command}{var} the Console Chapter
3136 In almost all cases, you should enclose the format specification (part
3137 after the equal sign) in double quotes. Please note that this directive
3138 is deprecated and is replaced in version 1.37 and greater with a Python
3139 script for creating volume names.
3143 In order for a Pool to be used during a Backup Job, the Pool must have at
3144 least one Volume associated with it. Volumes are created for a Pool using
3145 the {\bf label} or the {\bf add} commands in the {\bf Bacula Console},
3146 program. In addition to adding Volumes to the Pool (i.e. putting the
3147 Volume names in the Catalog database), the physical Volume must be labeled
3148 with a valid Bacula software volume label before {\bf Bacula} will accept
3149 the Volume. This will be automatically done if you use the {\bf label}
3150 command. Bacula can automatically label Volumes if instructed to do so,
3151 but this feature is not yet fully implemented.
3153 The following is an example of a valid Pool resource definition:
3165 \subsection{The Scratch Pool}
3166 \label{TheScratchPool}
3167 \index[general]{Scratch Pool}
3168 In general, you can give your Pools any name you wish, but there is one
3169 important restriction: the Pool named {\bf Scratch}, if it exists behaves
3170 like a scratch pool of Volumes in that when Bacula needs a new Volume for
3171 writing and it cannot find one, it will look in the Scratch pool, and if
3172 it finds an available Volume, it will move it out of the Scratch pool into
3173 the Pool currently being used by the job.
3176 \section{The Catalog Resource}
3177 \label{CatalogResource}
3178 \index[general]{Resource!Catalog}
3179 \index[general]{Catalog Resource}
3181 The Catalog Resource defines what catalog to use for the current job.
3182 Currently, Bacula can only handle a single database server (SQLite, MySQL,
3183 PostgreSQL) that is defined when configuring {\bf Bacula}. However, there
3184 may be as many Catalogs (databases) defined as you wish. For example, you
3185 may want each Client to have its own Catalog database, or you may want
3186 backup jobs to use one database and verify or restore jobs to use another
3189 Since SQLite is compiled in, it always runs on the same machine
3190 as the Director and the database must be directly accessible (mounted) from
3191 the Director. However, since both MySQL and PostgreSQL are networked
3192 databases, they may reside either on the same machine as the Director
3193 or on a different machine on the network. See below for more details.
3198 \index[dir]{Catalog}
3199 \index[dir]{Directive!Catalog}
3200 Start of the Catalog resource. At least one Catalog resource must be
3204 \item [Name = \lt{}name\gt{}]
3206 \index[dir]{Directive!Name}
3207 The name of the Catalog. No necessary relation to the database server
3208 name. This name will be specified in the Client resource directive
3209 indicating that all catalog data for that Client is maintained in this
3210 Catalog. This directive is required.
3212 \item [password = \lt{}password\gt{}]
3213 \index[dir]{password}
3214 \index[dir]{Directive!password}
3215 This specifies the password to use when logging into the database. This
3216 directive is required.
3218 \item [DB Name = \lt{}name\gt{}]
3219 \index[dir]{DB Name}
3220 \index[dir]{Directive!DB Name}
3221 This specifies the name of the database. If you use multiple catalogs
3222 (databases), you specify which one here. If you are using an external
3223 database server rather than the internal one, you must specify a name
3224 that is known to the server (i.e. you explicitly created the Bacula
3225 tables using this name. This directive is required.
3227 \item [user = \lt{}user\gt{}]
3229 \index[dir]{Directive!user}
3230 This specifies what user name to use to log into the database. This
3231 directive is required.
3233 \item [DB Socket = \lt{}socket-name\gt{}]
3234 \index[dir]{DB Socket}
3235 \index[dir]{Directive!DB Socket}
3236 This is the name of a socket to use on the local host to connect to the
3237 database. This directive is used only by MySQL and is ignored by SQLite.
3238 Normally, if neither {\bf DB Socket} or {\bf DB Address} are specified, MySQL
3239 will use the default socket. If the DB Socket is specified, the
3240 MySQL server must reside on the same machine as the Director.
3242 \item [DB Address = \lt{}address\gt{}]
3243 \index[dir]{DB Address}
3244 \index[dir]{Directive!DB Address}
3245 This is the host address of the database server. Normally, you would specify
3246 this instead of {\bf DB Socket} if the database server is on another machine.
3247 In that case, you will also specify {\bf DB Port}. This directive is used
3248 only by MySQL and PostgreSQL and is ignored by SQLite if provided.
3249 This directive is optional.
3251 \item [DB Port = \lt{}port\gt{}]
3252 \index[dir]{DB Port}
3253 \index[dir]{Directive!DB Port}
3254 This defines the port to be used in conjunction with {\bf DB Address} to
3255 access the database if it is on another machine. This directive is used only
3256 by MySQL and PostgreSQL and is ignored by SQLite if provided. This
3257 directive is optional.
3259 %% \item [Multiple Connections = \lt{}yes\vb{}no\gt{}]
3260 %% \index[dir]{Multiple Connections}
3261 %% \index[dir]{Directive!Multiple Connections}
3262 %% By default, this directive is set to no. In that case, each job that uses
3264 %% same Catalog will use a single connection to the catalog. It will be shared,
3265 %% and Bacula will allow only one Job at a time to communicate. If you set this
3266 %% directive to yes, Bacula will permit multiple connections to the database,
3267 %% and the database must be multi-thread capable. For SQLite and PostgreSQL,
3268 %% this is no problem. For MySQL, you must be *very* careful to have the
3269 %% multi-thread version of the client library loaded on your system. When this
3270 %% directive is set yes, each Job will have a separate connection to the
3271 %% database, and the database will control the interaction between the
3273 %% Jobs. This can significantly speed up the database operations if you are
3274 %% running multiple simultaneous jobs. In addition, for SQLite and PostgreSQL,
3275 %% Bacula will automatically enable transactions. This can significantly speed
3276 %% up insertion of attributes in the database either for a single Job or
3277 %% multiple simultaneous Jobs.
3279 %% This directive has not been tested. Please test carefully before running it
3280 %% in production and report back your results.
3284 The following is an example of a valid Catalog resource definition:
3293 password = "" # no password = no security
3298 or for a Catalog on another machine:

3323 \section{The Console Resource}
3324 \label{ConsoleResource1}
3325 \index[general]{Console Resource}
3326 \index[general]{Resource!Console}
3328 As of Bacula version 1.33 and higher, there are three different kinds of
3329 consoles, which the administrator or user can use to interact with the
3330 Director. These three kinds of consoles comprise three different security
3334 \item The first console type is an {\bf anonymous} or {\bf default} console,
3335 which has full privileges. There is no console resource necessary for
3336 this type since the password is specified in the Director's resource and
3337 consequently such consoles do not have a name as defined on a {\bf Name
3338 =} directive. This is the kind of console that was initially
3339 implemented in versions prior to 1.33 and remains valid. Typically you
3340 would use it only for administrators.
3342 \item The second type of console, and new to version 1.33 and higher is a
3343 "named" console defined within a Console resource in both the Director's
3344 configuration file and in the Console's configuration file. Both the
3345 names and the passwords in these two entries must match much as is the
3346 case for Client programs.
3348 This second type of console begins with absolutely no privileges except
3349 those explicitly specified in the Director's Console resource. Thus you
3350 can have multiple Consoles with different names and passwords, sort of
3351 like multiple users, each with different privileges. As a default,
3352 these consoles can do absolutely nothing -- no commands whatsoever. You
3353 give them privileges or rather access to commands and resources by
3354 specifying access control lists in the Director's Console resource. The
3355 ACLs are specified by a directive followed by a list of access names.
3356 Examples of this are shown below.
3358 \item The third type of console is similar to the above mentioned one in that
3359 it requires a Console resource definition in both the Director and the
3360 Console. In addition, if the console name, provided on the {\bf Name =}
3361 directive, is the same as a Client name, that console is permitted to
3362 use the {\bf SetIP} command to change the Address directive in the
3363 Director's client resource to the IP address of the Console. This
3364 permits portables or other machines using DHCP (non-fixed IP addresses)
3365 to "notify" the Director of their current IP address.
3368 The Console resource is optional and need not be specified. The following
3369 directives are permitted within the Director's configuration resource:
3373 \item [Name = \lt{}name\gt{}]
3375 \index[dir]{Directive!Name}
3376 The name of the console. This name must match the name specified in the
3377 Console's configuration resource (much as is the case with Client
3380 \item [Password = \lt{}password\gt{}]
3381 \index[dir]{Password}
3382 \index[dir]{Directive!Password}
3383 Specifies the password that must be supplied for a named Bacula Console
3384 to be authorized. The same password must appear in the {\bf Console}
3385 resource of the Console configuration file. For added security, the
3386 password is never actually passed across the network but rather a
3387 challenge response hash code created with the password. This directive
3388 is required. If you have either {\bf /dev/random} {\bf bc} on your
3389 machine, Bacula will generate a random password during the configuration
3390 process, otherwise it will be left blank.
3392 The password is plain text. It is not generated through any special
3393 process. However, it is preferable for security reasons to choose
3396 \item [JobACL = \lt{}name-list\gt{}]
3398 \index[dir]{Directive!JobACL}
3399 This directive is used to specify a list of Job resource names that can
3400 be accessed by the console. Without this directive, the console cannot
3401 access any of the Director's Job resources. Multiple Job resource names
3402 may be specified by separating them with commas, and/or by specifying
3403 multiple JobACL directives. For example, the directive may be specified
3408 JobACL = kernsave, "Backup client 1", "Backup client 2"
3409 JobACL = "RestoreFiles"
3414 With the above specification, the console can access the Director's resources
3415 for the four jobs named on the JobACL directives, but for no others.
3417 \item [ClientACL = \lt{}name-list\gt{}]
3418 \index[dir]{ClientACL}
3419 \index[dir]{Directive!ClientACL}
3420 This directive is used to specify a list of Client resource names that can
3422 accessed by the console.
3424 \item [StorageACL = \lt{}name-list\gt{}]
3425 \index[dir]{StorageACL}
3426 \index[dir]{Directive!StorageACL}
3427 This directive is used to specify a list of Storage resource names that can
3428 be accessed by the console.
3430 \item [ScheduleACL = \lt{}name-list\gt{}]
3431 \index[dir]{ScheduleACL}
3432 \index[dir]{Directive!ScheduleACL}
3433 This directive is used to specify a list of Schedule resource names that can
3434 be accessed by the console.
3436 \item [PoolACL = \lt{}name-list\gt{}]
3437 \index[dir]{PoolACL}
3438 \index[dir]{Directive!PoolACL}
3439 This directive is used to specify a list of Pool resource names that can be
3440 accessed by the console.
3442 \item [FileSetACL = \lt{}name-list\gt{}]
3443 \index[dir]{FileSetACL}
3444 \index[dir]{Directive!FileSetACL}
3445 This directive is used to specify a list of FileSet resource names that
3446 can be accessed by the console.
3448 \item [CatalogACL = \lt{}name-list\gt{}]
3449 \index[dir]{CatalogACL}
3450 \index[dir]{Directive!CatalogACL}
3451 This directive is used to specify a list of Catalog resource names that
3452 can be accessed by the console.
3454 \item [CommandACL = \lt{}name-list\gt{}]
3455 \index[dir]{CommandACL}
3456 \index[dir]{Directive!CommandACL}
3457 This directive is used to specify a list of of console commands that can

3460 \item [WhereACL = \lt{}string\gt{}]
3461 \index[dir]{WhereACL}
3462 \index[dir]{Directive!WhereACL}
3463 This directive permits you to specify where a restricted console
3464 can restore files. If this directive is not specified, only the
3465 default restore location is permitted (normally {\bf
3466 /tmp/bacula-restores}. If {\bf *all*} is specified any path the
3467 user enters will be accepted (not very secure), any other
3468 value specified (there may be multiple WhereACL directives) will
3469 restrict the user to use that path. For example, on a Unix system,
3470 if you specify "/", the file will be restored to the original
3471 location. This directive is untested.
3475 Aside from Director resource names and console command names, the special
3476 keyword {\bf *all*} can be specified in any of the above access control lists.
3477 When this keyword is present, any resource or command name (which ever is
3478 appropriate) will be accepted. For an example configuration file, please see
3480 \ilink{Console Configuration}{ConsoleConfChapter} chapter of this
3483 \section{The Counter Resource}
3484 \label{CounterResource}
3485 \index[general]{Resource!Counter}
3486 \index[general]{Counter Resource}
3488 The Counter Resource defines a counter variable that can be accessed by
3489 variable expansion used for creating Volume labels with the {\bf LabelFormat}
3491 \ilink{LabelFormat}{Label} directive in this chapter for more
3497 \index[dir]{Counter}
3498 \index[dir]{Directive!Counter}
3499 Start of the Counter resource. Counter directives are optional.
3501 \item [Name = \lt{}name\gt{}]
3503 \index[dir]{Directive!Name}
3504 The name of the Counter. This is the name you will use in the variable
3505 expansion to reference the counter value.
3507 \item [Minimum = \lt{}integer\gt{}]
3508 \index[dir]{Minimum}
3509 \index[dir]{Directive!Minimum}
3510 This specifies the minimum value that the counter can have. It also becomes
3511 the default. If not supplied, zero is assumed.
3513 \item [Maximum = \lt{}integer\gt{}]
3514 \index[dir]{Maximum}
3515 \index[dir]{Directive!Maximum}
3516 \index[dir]{Directive!Maximum}
3517 This is the maximum value value that the counter can have. If not specified
3518 or set to zero, the counter can have a maximum value of 2,147,483,648 (2 to
3519 the 31 power). When the counter is incremented past this value, it is reset
3522 \item [*WrapCounter = \lt{}counter-name\gt{}]
3523 \index[dir]{*WrapCounter}
3524 \index[dir]{Directive!*WrapCounter}
3525 If this value is specified, when the counter is incremented past the
3527 and thus reset to the minimum, the counter specified on the {\bf WrapCounter}
3528 is incremented. (This is not currently implemented).
3530 \item [Catalog = \lt{}catalog-name\gt{}]
3531 \index[dir]{Catalog}
3532 \index[dir]{Directive!Catalog}
3533 If this directive is specified, the counter and its values will be saved in
3534 the specified catalog. If this directive is not present, the counter will be
3535 redefined each time that Bacula is started.
