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}{DirectorResource} -- 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}{StorageResource} -- 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, \ldots{}).

87 \section{The Director Resource}
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 \label{Director:Director:Name}
104 \item [Name = \lt{}name\gt{}]
106 \index[dir]{Directive!Name}
107 The director name used by the system administrator. This directive is
110 \label{Director:Director:Description}
111 \item [Description = \lt{}text\gt{}]
112 \index[dir]{Description}
113 \index[dir]{Directive!Description}
114 The text field contains a description of the Director that will be displayed
115 in the graphical user interface. This directive is optional.
117 \label{Director:Director:Password}
118 \item [Password = \lt{}UA-password\gt{}]
119 \index[dir]{Password}
120 \index[dir]{Directive!Password}
121 Specifies the password that must be supplied for the default Bacula
122 Console to be authorized. The same password must appear in the {\bf
123 Director} resource of the Console configuration file. For added
124 security, the password is never passed across the network but instead a
125 challenge response hash code created with the password. This directive
126 is required. If you have either {\bf /dev/random} or {\bf bc} on your
127 machine, Bacula will generate a random password during the configuration
128 process, otherwise it will be left blank and you must manually supply
131 The password is plain text. It is not generated through any special
132 process but as noted above, it is better to use random text for
135 \label{Director:Director:Messages}
136 \item [Messages = \lt{}Messages-resource-name\gt{}]
137 \index[dir]{Directive!Messages}
138 The messages resource specifies where to deliver Director messages that are
139 not associated with a specific Job. Most messages are specific to a job and
140 will be directed to the Messages resource specified by the job. However,
141 there are a few messages that can occur when no job is running. This
142 directive is required.
144 \label{Director:Director:WorkingDirectory}
145 \item [Working Directory = \lt{}Directory\gt{}]
146 \index[dir]{Working Directory}
147 \index[dir]{Directive!Working Directory}
148 This directive is mandatory and specifies a directory in which the Director
149 may put its status files. This directory should be used only by Bacula but
150 may be shared by other Bacula daemons. However, please note, if this
151 directory is shared with other Bacula daemons (the File daemon and Storage
152 daemon), you must ensure that the {\bf Name} given to each daemon is
153 unique so that the temporary filenames used do not collide. By default
154 the Bacula configure process creates unique daemon names by postfixing them
155 with -dir, -fd, and -sd. Standard shell expansion of the {\bf
156 Directory} is done when the configuration file is read so that values such
157 as {\bf \$HOME} will be properly expanded. This directive is required.
158 The working directory specified must already exist and be
159 readable and writable by the Bacula daemon referencing it.
161 If you have specified a Director user and/or a Director group on your
162 ./configure line with {\bf {-}{-}with-dir-user} and/or
163 {\bf {-}{-}with-dir-group} the Working Directory owner and group will
164 be set to those values.
166 \label{Director:Director:PidDirectory}
167 \item [Pid Directory = \lt{}Directory\gt{}]
168 \index[dir]{Pid Directory}
169 \index[dir]{Directive!Pid Directory}
170 This directive is mandatory and specifies a directory in which the Director
171 may put its process Id file. The process Id file is used to shutdown
172 Bacula and to prevent multiple copies of Bacula from running simultaneously.
173 Standard shell expansion of the {\bf Directory} is done when the
174 configuration file is read so that values such as {\bf \$HOME} will be
177 The PID directory specified must already exist and be
178 readable and writable by the Bacula daemon referencing it
180 Typically on Linux systems, you will set this to: {\bf /var/run}. If you are
181 not installing Bacula in the system directories, you can use the {\bf Working
182 Directory} as defined above. This directive is required.
184 \label{Director:Director:ScriptsDirectory}
185 \item [Scripts Directory = \lt{}Directory\gt{}]
186 \index[dir]{Scripts Directory}
187 \index[dir]{Directive!Scripts Directory}
188 This directive is optional and, if defined, specifies a directory in
189 which the Director will look for the Python startup script {\bf
190 DirStartup.py}. This directory may be shared by other Bacula daemons.
191 Standard shell expansion of the directory is done when the configuration
192 file is read so that values such as {\bf \$HOME} will be properly
195 \label{Director:Director:QueryFile}
196 \item [QueryFile = \lt{}Path\gt{}]
197 \index[dir]{QueryFile}
198 \index[dir]{Directive!QueryFile}
199 This directive is mandatory and specifies a directory and file in which
200 the Director can find the canned SQL statements for the {\bf Query}
201 command of the Console. Standard shell expansion of the {\bf Path} is
202 done when the configuration file is read so that values such as {\bf
203 \$HOME} will be properly expanded. This directive is required.
205 \label{Director:Director:HeartbeatInterval}
206 \item [Heartbeat Interval = \lt{}time-interval\gt{}]
207 \index[dir]{Heartbeat Interval}
208 \index[dir]{Directive!Heartbeat}
209 This directive is optional and if specified will cause the Director to
210 set a keepalive interval (heartbeat) in seconds on each of the sockets
211 it opens for the Client resource. This value will override any
212 specified at the Director level. It is implemented only on systems
213 (Linux, \ldots{}) that provide the {\bf setsockopt} TCP\_KEEPIDLE function.
214 The default value is zero, which means no change is made to the socket.
216 \label{DirMaxConJobs}
218 \label{Director:Director:MaximumConcurrentJobs}
219 \item [Maximum Concurrent Jobs = \lt{}number\gt{}]
220 \index[dir]{Maximum Concurrent Jobs}
221 \index[dir]{Directive!Maximum Concurrent Jobs}
222 \index[general]{Simultaneous Jobs}
223 \index[general]{Concurrent Jobs}
224 where \lt{}number\gt{} is the maximum number of total Director Jobs that
225 should run concurrently. The default is set to 1, but you may set it to a
228 The Volume format becomes more complicated with
229 multiple simultaneous jobs, consequently, restores may take longer if
230 Bacula must sort through interleaved volume blocks from multiple simultaneous
231 jobs. This can be avoided by having each simultaneous job write to
232 a different volume or by using data spooling, which will first spool the data
233 to disk simultaneously, then write one spool file at a time to the volume
234 thus avoiding excessive interleaving of the different job blocks.
236 \label{Director:Director:FdConnectTimeout}
237 \item [FD Connect Timeout = \lt{}time\gt{}]
238 \index[dir]{FD Connect Timeout}
239 \index[dir]{Directive!FD Connect Timeout}
240 where {\bf time} is the time that the Director should continue
241 attempting to contact the File daemon to start a job, and after which
242 the Director will cancel the job. The default is 30 minutes.
244 \label{Director:Director:SdConnectTimeout}
245 \item [SD Connect Timeout = \lt{}time\gt{}]
246 \index[dir]{SD Connect Timeout}
247 \index[dir]{Directive!SD Connect Timeout}
248 where {\bf time} is the time that the Director should continue
249 attempting to contact the Storage daemon to start a job, and after which
250 the Director will cancel the job. The default is 30 minutes.
252 \label{Director:Director:DirAddresses}
253 \item [DirAddresses = \lt{}IP-address-specification\gt{}]
254 \index[dir]{DirAddresses}
256 \index[general]{Address}
257 \index[dir]{Directive!DirAddresses}
258 Specify the ports and addresses on which the Director daemon will listen
259 for Bacula Console connections. Probably the simplest way to explain
260 this is to show an example:
265 ip = { addr = 1.2.3.4; port = 1205;}
267 addr = 1.2.3.4; port = http;}
276 ip = { addr = 1.2.3.4 }
277 ip = { addr = 201:220:222::2 }
279 addr = bluedot.thun.net
285 where ip, ip4, ip6, addr, and port are all keywords. Note, that the address
286 can be specified as either a dotted quadruple, or IPv6 colon notation, or as
287 a symbolic name (only in the ip specification). Also, port can be specified
288 as a number or as the mnemonic value from the /etc/services file. If a port
289 is not specified, the default will be used. If an ip section is specified,
290 the resolution can be made either by IPv4 or IPv6. If ip4 is specified, then
291 only IPv4 resolutions will be permitted, and likewise with ip6.
293 Please note that if you use the DirAddresses directive, you must
294 not use either a DirPort or a DirAddress directive in the same
297 \label{Director:Director:DirPort}
298 \item [DirPort = \lt{}port-number\gt{}]
300 \index[dir]{Directive!DirPort}
301 Specify the port (a positive integer) on which the Director daemon will
302 listen for Bacula Console connections. This same port number must be
303 specified in the Director resource of the Console configuration file. The
304 default is 9101, so normally this directive need not be specified. This
305 directive should not be used if you specify DirAddresses (N.B plural)
308 \label{Director:Director:DirAddress}
309 \item [DirAddress = \lt{}IP-Address\gt{}]
310 \index[dir]{DirAddress}
311 \index[dir]{Directive!DirAddress}
312 This directive is optional, but if it is specified, it will cause the
313 Director server (for the Console program) to bind to the specified {\bf
314 IP-Address}, which is either a domain name or an IP address specified as a
315 dotted quadruple in string or quoted string format. If this directive is
316 not specified, the Director will bind to any available address (the
317 default). Note, unlike the DirAddresses specification noted above, this
318 directive only permits a single address to be specified. This directive
319 should not be used if you specify a DirAddresses (N.B. plural) directive.
321 \label{Director:Director:DirSourceAddress}
322 \item [DirSourceAddress = \lt{}IP-Address\gt{}]
323 \index[fd]{DirSourceAddress}
324 \index[fd]{Directive!DirSourceAddress}
325 This record is optional, and if it is specified, it will cause the Director
326 server (when initiating connections to a storage or file daemon) to source
327 its connections from the specified address. Only a single IP address may be
328 specified. If this record is not specified, the Director server will source
329 its outgoing connections according to the system routing table (the default).
332 \label{Director:Director:StatisticsRetention}
333 \item[Statistics Retention = \lt{}time\gt{}]
334 \index[dir]{StatisticsRetention}
335 \label{PruneStatistics}
336 \index[dir]{Directive!StatisticsRetention}
338 The \texttt{Statistics Retention} directive defines the length of time that
339 Bacula will keep statistics job records in the Catalog database after the
340 Job End time. (In \texttt{JobHistory} table) When this time period expires,
341 and if user runs \texttt{prune stats} command, Bacula will prune (remove)
342 Job records that are older than the specified period.
344 Theses statistics records aren't use for restore purpose, but mainly for
345 capacity planning, billings, etc. See \ilink{Statistics chapter}{UseBaculaCatalogToExtractInformationChapter} for
346 additional information.
348 See the \ilink{ Configuration chapter}{Time} of this manual for additional
349 details of time specification.
351 The default is 5 years.
353 \label{Director:Director:VerId}
354 \item[VerId = \lt{}string\gt{}]
355 \index[dir]{Directive!VerId}
356 where \lt{}string\gt{} is an identifier which can be used for support purpose.
357 This string is displayed using the \texttt{version} command.

360 \item[MaximumConsoleConnections = \lt{}number\gt{}]
361 \index[dir]{MaximumConsoleConnections}
362 \index[dir]{Directive!MaximumConsoleConnections}
364 where \lt{}number\gt{} is the maximum number of Console Connections that
365 could run concurrently. The default is set to 20, but you may set it to a

369 \item[MaximumReloadRequests = \lt{}number\gt{}]
370 \index[dir]{MaximumReloadRequests}
371 \index[dir]{Directive!MaximumReloadRequests}
374 Where \lt{}number\gt{} is the maximum number of \texttt{reload} command that
375 can be done while jobs are running. The default is set to 32 and is usually

426 \section{The Job Resource}
427 \index[general]{Resource!Job}
428 \index[general]{Job Resource}
430 The Job resource defines a Job (Backup, Restore, \ldots{}) that Bacula must
431 perform. Each Job resource definition contains the name of a Client and
432 a FileSet to backup, the Schedule for the Job, where the data
433 are to be stored, and what media Pool can be used. In effect, each Job
434 resource must specify What, Where, How, and When or FileSet, Storage,
435 Backup/Restore/Level, and Schedule respectively. Note, the FileSet must
436 be specified for a restore job for historical reasons, but it is no longer used.
438 Only a single type ({\bf Backup}, {\bf Restore}, \ldots{}) can be specified for any
439 job. If you want to backup multiple FileSets on the same Client or multiple
440 Clients, you must define a Job for each one.
442 Note, you define only a single Job to do the Full, Differential, and
443 Incremental backups since the different backup levels are tied together by
444 a unique Job name. Normally, you will have only one Job per Client, but
445 if a client has a really huge number of files (more than several million),
446 you might want to split it into to Jobs each with a different FileSet
447 covering only part of the total files.
449 Multiple Storage daemons are not currently supported for Jobs, so if
450 you do want to use multiple storage daemons, you will need to create
451 a different Job and ensure that for each Job that the combination of
452 Client and FileSet are unique. The Client and FileSet are what Bacula
453 uses to restore a client, so if there are multiple Jobs with the same
454 Client and FileSet or multiple Storage daemons that are used, the
455 restore will not work. This problem can be resolved by defining multiple
456 FileSet definitions (the names must be different, but the contents of
457 the FileSets may be the same).
464 \index[dir]{Directive!Job}
465 Start of the Job resource. At least one Job resource is required.
467 \label{Director:Job:Name}
468 \item [Name = \lt{}name\gt{}]
470 \index[dir]{Directive!Name}
471 The Job name. This name can be specified on the {\bf Run} command in the
472 console program to start a job. If the name contains spaces, it must be
473 specified between quotes. It is generally a good idea to give your job the
474 same name as the Client that it will backup. This permits easy
475 identification of jobs.
477 When the job actually runs, the unique Job Name will consist of the name you
478 specify here followed by the date and time the job was scheduled for
479 execution. This directive is required.
481 \label{Director:Job:Enabled}
482 \item [Enabled = \lt{}yes\vb{}no\gt{}]
484 \index[dir]{Directive!Enable}
485 This directive allows you to enable or disable automatic execution
486 via the scheduler of a Job.
488 \label{Director:Job:Type}
489 \item [Type = \lt{}job-type\gt{}]
491 \index[dir]{Directive!Type}
492 The {\bf Type} directive specifies the Job type, which may be one of the
493 following: {\bf Backup}, {\bf Restore}, {\bf Verify}, or {\bf Admin}. This
494 directive is required. Within a particular Job Type, there are also Levels
495 as discussed in the next item.
501 Run a backup Job. Normally you will have at least one Backup job for each
502 client you want to save. Normally, unless you turn off cataloging, most all
503 the important statistics and data concerning files backed up will be placed
508 Run a restore Job. Normally, you will specify only one Restore job
509 which acts as a sort of prototype that you will modify using the console
510 program in order to perform restores. Although certain basic
511 information from a Restore job is saved in the catalog, it is very
512 minimal compared to the information stored for a Backup job -- for
513 example, no File database entries are generated since no Files are
516 {\bf Restore} jobs cannot be
517 automatically started by the scheduler as is the case for Backup, Verify
518 and Admin jobs. To restore files, you must use the {\bf restore} command
524 Run a verify Job. In general, {\bf verify} jobs permit you to compare the
525 contents of the catalog to the file system, or to what was backed up. In
526 addition, to verifying that a tape that was written can be read, you can
527 also use {\bf verify} as a sort of tripwire intrusion detection.
531 Run an admin Job. An {\bf Admin} job can be used to periodically run catalog
532 pruning, if you do not want to do it at the end of each {\bf Backup} Job.
533 Although an Admin job is recorded in the catalog, very little data is saved.
538 \label{Director:Job:Level}
539 \item [Level = \lt{}job-level\gt{}]
541 \index[dir]{Directive!Level}
542 The Level directive specifies the default Job level to be run. Each
543 different Job Type (Backup, Restore, \ldots{}) has a different set of Levels
544 that can be specified. The Level is normally overridden by a different
545 value that is specified in the {\bf Schedule} resource. This directive
546 is not required, but must be specified either by a {\bf Level} directive
547 or as an override specified in the {\bf Schedule} resource.
549 For a {\bf Backup} Job, the Level may be one of the following:
555 When the Level is set to Full all files in the FileSet whether or not
556 they have changed will be backed up.
559 \index[dir]{Incremental}
560 When the Level is set to Incremental all files specified in the FileSet
561 that have changed since the last successful backup of the the same Job
562 using the same FileSet and Client, will be backed up. If the Director
563 cannot find a previous valid Full backup then the job will be upgraded
564 into a Full backup. When the Director looks for a valid backup record
565 in the catalog 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, Differential, or Incremental 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 Incremental to a Full save. Otherwise, the Incremental backup will be
580 performed as requested.
582 The File daemon (Client) decides which files to backup for an
583 Incremental backup by comparing start time of the prior Job (Full,
584 Differential, or Incremental) against the time each file was last
585 ``modified'' (st\_mtime) and the time its attributes were last
586 ``changed''(st\_ctime). If the file was modified or its attributes
587 changed on or after this start time, it will then be backed up.
589 Some virus scanning software may change st\_ctime while
590 doing the scan. For example, if the virus scanning program attempts to
591 reset the access time (st\_atime), which Bacula does not use, it will
592 cause st\_ctime to change and hence Bacula will backup the file during
593 an Incremental or Differential backup. In the case of Sophos virus
594 scanning, you can prevent it from resetting the access time (st\_atime)
595 and hence changing st\_ctime by using the {\bf \lstinline:--:no-reset-atime}
596 option. For other software, please see their manual.
598 When Bacula does an Incremental backup, all modified files that are
599 still on the system are backed up. However, any file that has been
600 deleted since the last Full backup remains in the Bacula catalog,
601 which means that if between a Full save and the time you do a
602 restore, some files are deleted, those deleted files will also be
603 restored. The deleted files will no longer appear in the catalog
604 after doing another Full save.
606 In addition, if you move a directory rather than copy it, the files in
607 it do not have their modification time (st\_mtime) or their attribute
608 change time (st\_ctime) changed. As a consequence, those files will
609 probably not be backed up by an Incremental or Differential backup which
610 depend solely on these time stamps. If you move a directory, and wish
611 it to be properly backed up, it is generally preferable to copy it, then
614 However, to manage deleted files or directories changes in the
615 catalog during an Incremental backup you can use \texttt{accurate}
616 mode. This is quite memory consuming process. See \ilink{Accurate
617 mode}{accuratemode} for more details.
620 \index[dir]{Differential}
621 When the Level is set to Differential
622 all files specified in the FileSet that have changed since the last
623 successful Full backup of the same Job will be backed up.
624 If the Director cannot find a
625 valid previous Full backup for the same Job, FileSet, and Client,
626 backup, then the Differential job will be upgraded into a Full backup.
627 When the Director looks for a valid Full backup record in the catalog
628 database, it looks for a previous Job with:
631 \item The same Job name.
632 \item The same Client name.
633 \item The same FileSet (any change to the definition of the FileSet such as
634 adding or deleting a file in the Include or Exclude sections constitutes a
636 \item The Job was a FULL backup.
637 \item The Job terminated normally (i.e. did not fail or was not canceled).
638 \item The Job started no longer ago than {\bf Max Full Interval}.
641 If all the above conditions do not hold, the Director will upgrade the
642 Differential to a Full save. Otherwise, the Differential backup will be
643 performed as requested.
645 The File daemon (Client) decides which files to backup for a
646 differential backup by comparing the start time of the prior Full backup
647 Job against the time each file was last ``modified'' (st\_mtime) and the
648 time its attributes were last ``changed'' (st\_ctime). If the file was
649 modified or its attributes were changed on or after this start time, it
650 will then be backed up. The start time used is displayed after the {\bf
651 Since} on the Job report. In rare cases, using the start time of the
652 prior backup may cause some files to be backed up twice, but it ensures
653 that no change is missed. As with the Incremental option, you should
654 ensure that the clocks on your server and client are synchronized or as
655 close as possible to avoid the possibility of a file being skipped.
656 Note, on versions 1.33 or greater Bacula automatically makes the
657 necessary adjustments to the time between the server and the client so
658 that the times Bacula uses are synchronized.
660 When Bacula does a Differential backup, all modified files that are
661 still on the system are backed up. However, any file that has been
662 deleted since the last Full backup remains in the Bacula catalog, which
663 means that if between a Full save and the time you do a restore, some
664 files are deleted, those deleted files will also be restored. The
665 deleted files will no longer appear in the catalog after doing another
666 Full save. However, to remove deleted files from the catalog during a
667 Differential backup is quite a time consuming process and not currently
668 implemented in Bacula. It is, however, a planned future feature.
670 As noted above, if you move a directory rather than copy it, the
671 files in it do not have their modification time (st\_mtime) or
672 their attribute change time (st\_ctime) changed. As a
673 consequence, those files will probably not be backed up by an
674 Incremental or Differential backup which depend solely on these
675 time stamps. If you move a directory, and wish it to be
676 properly backed up, it is generally preferable to copy it, then
677 delete the original. Alternatively, you can move the directory, then
678 use the {\bf touch} program to update the timestamps.
680 %% TODO: merge this with incremental
681 However, to manage deleted files or directories changes in the
682 catalog during an Differential backup you can use \texttt{accurate}
683 mode. This is quite memory consuming process. See \ilink{Accurate
684 mode}{accuratemode} for more details.
686 Every once and a while, someone asks why we need Differential
687 backups as long as Incremental backups pickup all changed files.
688 There are possibly many answers to this question, but the one
689 that is the most important for me is that a Differential backup
691 all the Incremental and Differential backups since the last Full backup
692 into a single Differential backup. This has two effects: 1. It gives
693 some redundancy since the old backups could be used if the merged backup
694 cannot be read. 2. More importantly, it reduces the number of Volumes
695 that are needed to do a restore effectively eliminating the need to read
696 all the volumes on which the preceding Incremental and Differential
697 backups since the last Full are done.
700 \index[dir]{VirtualFull}
702 When the Level is set to VirtualFull, it permits you to consolidate the
703 previous Full backup plus the most recent Differential backup and any
704 subsequent Incremental backups into a new Full backup. This new Full backup
705 will then be considered as the most recent Full for any future Incremental
706 or Differential backups. The VirtualFull backup is accomplished without
707 contacting the client by reading the previous backup data and writing it to
708 a volume in a different pool.
710 Bacula's virtual backup feature is often called Synthetic Backup or
711 Consolidation in other backup products.
715 For a {\bf Restore} Job, no level needs to be specified.
717 For a {\bf Verify} Job, the Level may be one of the following:
722 \index[dir]{InitCatalog}
723 does a scan of the specified {\bf FileSet} and stores the file
724 attributes in the Catalog database. Since no file data is saved, you
725 might ask why you would want to do this. It turns out to be a very
726 simple and easy way to have a {\bf Tripwire} like feature using {\bf
727 Bacula}. In other words, it allows you to save the state of a set of
728 files defined by the {\bf FileSet} and later check to see if those files
729 have been modified or deleted and if any new files have been added.
730 This can be used to detect system intrusion. Typically you would
731 specify a {\bf FileSet} that contains the set of system files that
732 should not change (e.g. /sbin, /boot, /lib, /bin, \ldots{}). Normally, you
733 run the {\bf InitCatalog} level verify one time when your system is
734 first setup, and then once again after each modification (upgrade) to
735 your system. Thereafter, when your want to check the state of your
736 system files, you use a {\bf Verify} {\bf level = Catalog}. This
737 compares the results of your {\bf InitCatalog} with the current state of
742 Compares the current state of the files against the state previously
743 saved during an {\bf InitCatalog}. Any discrepancies are reported. The
744 items reported are determined by the {\bf verify} options specified on
745 the {\bf Include} directive in the specified {\bf FileSet} (see the {\bf
746 FileSet} resource below for more details). Typically this command will
747 be run once a day (or night) to check for any changes to your system
750 Please note! If you run two Verify Catalog jobs on the same client at
751 the same time, the results will certainly be incorrect. This is because
752 Verify Catalog modifies the Catalog database while running in order to
755 \item [VolumeToCatalog]
756 \index[dir]{VolumeToCatalog}
757 This level causes Bacula to read the file attribute data written to the
758 Volume from the last backup Job for the job specified on the {\bf VerifyJob}
759 directive. The file attribute data are compared to the
760 values saved in the Catalog database and any differences are reported.
761 This is similar to the {\bf DiskToCatalog} level except that instead of
762 comparing the disk file attributes to the catalog database, the
763 attribute data written to the Volume is read and compared to the catalog
764 database. Although the attribute data including the signatures (MD5 or
765 SHA1) are compared, the actual file data is not compared (it is not in
768 Please note! If you run two Verify VolumeToCatalog jobs on the same
769 client at the same time, the results will certainly be incorrect. This
770 is because the Verify VolumeToCatalog modifies the Catalog database
773 \item [DiskToCatalog]
774 \index[dir]{DiskToCatalog}
775 This level causes Bacula to read the files as they currently are on
776 disk, and to compare the current file attributes with the attributes
777 saved in the catalog from the last backup for the job specified on the
778 {\bf VerifyJob} directive. This level differs from the {\bf VolumeToCatalog}
779 level described above by the fact that it doesn't compare against a
780 previous Verify job but against a previous backup. When you run this
781 level, you must supply the verify options on your Include statements.
782 Those options determine what attribute fields are compared.
784 This command can be very useful if you have disk problems because it
785 will compare the current state of your disk against the last successful
786 backup, which may be several jobs.
788 Note, the current implementation (1.32c) does not identify files that
792 \label{Director:Job:Accurate}
793 \item [Accurate = \lt{}yes\vb{}no\gt{}]
794 \index[dir]{Accurate}
795 In accurate mode, the File daemon knowns exactly which files were present
796 after the last backup. So it is able to handle deleted or renamed files.
798 When restoring a FileSet for a specified date (including ``most
799 recent''), Bacula is able to restore exactly the files and
800 directories that existed at the time of the last backup prior to
801 that date including ensuring that deleted files are actually deleted,
802 and renamed directories are restored properly.
804 In this mode, the File daemon must keep data concerning all files in
805 memory. So If you do not have sufficient memory, the backup may
806 either be terribly slow or fail.
808 %% $$ memory = \sum_{i=1}^{n}(strlen(path_i + file_i) + sizeof(CurFile))$$
810 For 500.000 files (a typical desktop linux system), it will require
811 approximately 64 Megabytes of RAM on your File daemon to hold the
812 required information.

816 \index[dir]{Verify Job}
817 \index[dir]{Directive!Verify Job}
818 If you run a verify job without this directive, the last job run will be
819 compared with the catalog, which means that you must immediately follow
820 a backup by a verify command. If you specify a {\bf Verify Job} Bacula
821 will find the last job with that name that ran. This permits you to run
822 all your backups, then run Verify jobs on those that you wish to be
823 verified (most often a {\bf VolumeToCatalog}) so that the tape just

830 If a JobDefs-Resource-Name is specified, all the values contained in the
831 named JobDefs resource will be used as the defaults for the current Job.
832 Any value that you explicitly define in the current Job resource, will
833 override any defaults specified in the JobDefs resource. The use of
834 this directive permits writing much more compact Job resources where the
835 bulk of the directives are defined in one or more JobDefs. This is
836 particularly useful if you have many similar Jobs but with minor
837 variations such as different Clients. A simple example of the use of
838 JobDefs is provided in the default bacula-dir.conf file.
840 \label{Director:Job:Bootstrap}
841 \item [Bootstrap = \lt{}bootstrap-file\gt{}]
842 \index[dir]{Bootstrap}
843 \index[dir]{Directive!Bootstrap}
844 The Bootstrap directive specifies a bootstrap file that, if provided,
845 will be used during {\bf Restore} Jobs and is ignored in other Job
846 types. The {\bf bootstrap} file contains the list of tapes to be used
847 in a restore Job as well as which files are to be restored.
848 Specification of this directive is optional, and if specified, it is
849 used only for a restore job. In addition, when running a Restore job
850 from the console, this value can be changed.
852 If you use the {\bf Restore} command in the Console program, to start a
853 restore job, the {\bf bootstrap} file will be created automatically from
854 the files you select to be restored.
856 For additional details of the {\bf bootstrap} file, please see

864 \index[dir]{Directive!Write Bootstrap}
865 The {\bf writebootstrap} directive specifies a file name where Bacula
866 will write a {\bf bootstrap} file for each Backup job run. This
867 directive applies only to Backup Jobs. If the Backup job is a Full
868 save, Bacula will erase any current contents of the specified file
869 before writing the bootstrap records. If the Job is an Incremental
871 save, Bacula will append the current bootstrap record to the end of the
874 Using this feature, permits you to constantly have a bootstrap file that
875 can recover the current state of your system. Normally, the file
876 specified should be a mounted drive on another machine, so that if your
877 hard disk is lost, you will immediately have a bootstrap record
878 available. Alternatively, you should copy the bootstrap file to another
879 machine after it is updated. Note, it is a good idea to write a separate
880 bootstrap file for each Job backed up including the job that backs up
881 your catalog database.
883 If the {\bf bootstrap-file-specification} begins with a vertical bar
884 (\lstinline+|+), Bacula will use the specification as the name of a program to which
885 it will pipe the bootstrap record. It could for example be a shell
886 script that emails you the bootstrap record.
888 On versions 1.39.22 or greater, before opening the file or executing the
889 specified command, Bacula performs
890 \ilink{character substitution}{character substitution} like in RunScript
891 directive. To automatically manage your bootstrap files, you can use
892 this in your {\bf JobDefs} resources:
895 Write Bootstrap = "%c_%n.bsr"

906 \index[dir]{Directive!Client}
907 The Client directive specifies the Client (File daemon) that will be used in
908 the current Job. Only a single Client may be specified in any one Job. The
909 Client runs on the machine to be backed up, and sends the requested files to
910 the Storage daemon for backup, or receives them when restoring. For
911 additional details, see the
912 \ilink{Client Resource section}{ClientResource} of this chapter.
913 This directive is required.

916 \item [FileSet = \lt{}FileSet-resource-name\gt{}]
918 \index[dir]{Directive!FileSet}
919 The FileSet directive specifies the FileSet that will be used in the
920 current Job. The FileSet specifies which directories (or files) are to
921 be backed up, and what options to use (e.g. compression, \ldots{}). Only a
922 single FileSet resource may be specified in any one Job. For additional
923 details, see the \ilink{FileSet Resource section}{FileSetResource} of
924 this chapter. This directive is required.
926 \label{Director:Job:Base}
927 \item [Base = \lt{}job-resource-name, \ldots{}\gt{}]
929 \index[dir]{Directive!Base}
930 The Base directive permits to specify the list of jobs that will be used during
931 Full backup as base. This directive is optional. See the \ilink{Base Job
932 chapter}{basejobs} for more information.
934 \label{Director:Job:Messages}
935 \item [Messages = \lt{}messages-resource-name\gt{}]
936 \index[dir]{Messages}
937 \index[dir]{Directive!Messages}
938 The Messages directive defines what Messages resource should be used for
939 this job, and thus how and where the various messages are to be
940 delivered. For example, you can direct some messages to a log file, and
941 others can be sent by email. For additional details, see the
942 \ilink{Messages Resource}{MessagesChapter} Chapter of this manual. This
943 directive is required.
945 \label{Director:Job:Pool}
946 \item [Pool = \lt{}pool-resource-name\gt{}]
948 \index[dir]{Directive!Pool}
949 The Pool directive defines the pool of Volumes where your data can be
950 backed up. Many Bacula installations will use only the {\bf Default}
951 pool. However, if you want to specify a different set of Volumes for
952 different Clients or different Jobs, you will probably want to use
953 Pools. For additional details, see the \ilink{Pool Resource
954 section}{PoolResource} of this chapter. This directive is required.

966 \index[dir]{Differential Backup Pool}
967 \index[dir]{Directive!Differential Backup Pool}
968 The {\it Differential Backup Pool} specifies a Pool to be used for

974 \index[dir]{Incremental Backup Pool}
975 \index[dir]{Directive!Incremental Backup Pool}
976 The {\it Incremental Backup Pool} specifies a Pool to be used for
977 Incremental backups. It will override any Pool specification during an
978 Incremental backup. This directive is optional.
980 \label{Director:Job:Schedule}
981 \item [Schedule = \lt{}schedule-name\gt{}]
982 \index[dir]{Schedule}
983 \index[dir]{Directive!Schedule}
984 The Schedule directive defines what schedule is to be used for the Job.
985 The schedule in turn determines when the Job will be automatically
986 started and what Job level (i.e. Full, Incremental, \ldots{}) is to be run.
987 This directive is optional, and if left out, the Job can only be started
988 manually using the Console program. Although you may specify only a
989 single Schedule resource for any one job, the Schedule resource may
990 contain multiple {\bf Run} directives, which allow you to run the Job at
991 many different times, and each {\bf run} directive permits overriding
992 the default Job Level Pool, Storage, and Messages resources. This gives
993 considerable flexibility in what can be done with a single Job. For
994 additional details, see the \ilink{Schedule Resource
995 Chapter}{ScheduleResource} of this manual.

1003 want to backup the FileSet data. For additional details, see the
1004 \ilink{Storage Resource Chapter}{StorageResource} of this manual.
1005 The Storage resource may also be specified in the Job's Pool resource,
1006 in which case the value in the Pool resource overrides any value
1007 in the Job. This Storage resource definition is not required by either
1008 the Job resource or in the Pool, but it must be specified in
1009 one or the other, if not an error will result.

1015 The time specifies the maximum delay between the scheduled time and the
1016 actual start time for the Job. For example, a job can be scheduled to
1017 run at 1:00am, but because other jobs are running, it may wait to run.
1018 If the delay is set to 3600 (one hour) and the job has not begun to run
1019 by 2:00am, the job will be canceled. This can be useful, for example,
1020 to prevent jobs from running during day time hours. The default is 0
1021 which indicates no limit.

1105 \index[dir]{Prefer Mounted Volumes}
1106 \index[dir]{Directive!Prefer Mounted Volumes}
1107 If the Prefer Mounted Volumes directive is set to {\bf yes} (default
1108 yes), the Storage daemon is requested to select either an Autochanger or
1109 a drive with a valid Volume already mounted in preference to a drive
1110 that is not ready. This means that all jobs will attempt to append
1111 to the same Volume (providing the Volume is appropriate -- right Pool,
1112 \ldots{} for that job), unless you are using multiple pools.
1113 If no drive with a suitable Volume is available, it
1114 will select the first available drive. Note, any Volume that has
1115 been requested to be mounted, will be considered valid as a mounted
1116 volume by another job. This if multiple jobs start at the same time
1117 and they all prefer mounted volumes, the first job will request the
1118 mount, and the other jobs will use the same volume.
1120 If the directive is set to {\bf no}, the Storage daemon will prefer
1121 finding an unused drive, otherwise, each job started will append to the
1122 same Volume (assuming the Pool is the same for all jobs). Setting
1123 Prefer Mounted Volumes to no can be useful for those sites
1124 with multiple drive autochangers that prefer to maximize backup
1125 throughput at the expense of using additional drives and Volumes.
1126 This means that the job will prefer to use an unused drive rather
1127 than use a drive that is already in use.
1129 Despite the above, we recommend against setting this directive to
1131 it tends to add a lot of swapping of Volumes between the different
1132 drives and can easily lead to deadlock situations in the Storage
1133 daemon. We will accept bug reports against it, but we cannot guarantee
1134 that we will be able to fix the problem in a reasonable time.
1136 A better alternative for using multiple drives is to use multiple
1137 pools so that Bacula will be forced to mount Volumes from those Pools
1138 on different drives.

1153 \index[dir]{Prune Files}
1154 \index[dir]{Directive!Prune Files}
1155 Normally, pruning of Files from the Catalog is specified on a Client by
1156 Client basis in the Client resource with the {\bf AutoPrune} directive.
1157 If this directive is specified (not normally) and the value is {\bf
1158 yes}, it will override the value specified in the Client resource. The
1159 default is {\bf no}.

1162 \item [Prune Volumes = \lt{}yes\vb{}no\gt{}]
1163 \index[dir]{Prune Volumes}
1164 \index[dir]{Directive!Prune Volumes}
1165 Normally, pruning of Volumes from the Catalog is specified on a Pool by
1166 Pool basis in the Pool resource with the {\bf AutoPrune} directive.
1167 Note, this is different from File and Job pruning which is done on a
1168 Client by Client basis. If this directive is specified (not normally)
1169 and the value is {\bf yes}, it will override the value specified in the
1170 Pool resource. The default is {\bf no}.

1173 \item [RunScript \{\lt{}body-of-runscript\gt{}\}]
1174 \index[dir]{RunScript}
1175 \index[dir]{Directive!Run Script}
1177 The RunScript directive behaves like a resource in that it
1178 requires opening and closing braces around a number of directives
1179 that make up the body of the runscript.
1181 The specified {\bf Command} (see below for details) is run as an external
1182 program prior or after the current Job. This is optional. By default, the
1183 program is executed on the Client side like in \texttt{ClientRunXXXJob}.
1185 \textbf{Console} options are special commands that are sent to the director instead
1186 of the OS. At this time, console command ouputs are redirected to log with
1189 You can use following console command : \texttt{delete}, \texttt{disable},
1190 \texttt{enable}, \texttt{estimate}, \texttt{list}, \texttt{llist},
1191 \texttt{memory}, \texttt{prune}, \texttt{purge}, \texttt{reload},
1192 \texttt{status}, \texttt{setdebug}, \texttt{show}, \texttt{time},
1193 \texttt{trace}, \texttt{update}, \texttt{version}, \texttt{.client},
1194 \texttt{.jobs}, \texttt{.pool}, \texttt{.storage}. See console chapter for
1195 more information. You need to specify needed information on command line, nothing
1196 will be prompted. Example :
1199 Console = "prune files client=%c"
1200 Console = "update stats age=3"
1203 You can specify more than one Command/Console option per RunScript.
1205 You can use following options may be specified in the body
1207 \LTXtable{0.95\linewidth}{table_runscript}
1209 Any output sent by the command to standard output will be included in the
1210 Bacula job report. The command string must be a valid program name or name
1213 In addition, the command string is parsed then fed to the OS,
1214 which means that the path will be searched to execute your specified
1215 command, but there is no shell interpretation, as a consequence, if you
1216 invoke complicated commands or want any shell features such as redirection
1217 or piping, you must call a shell script and do it inside that script.
1219 Before submitting the specified command to the operating system, Bacula
1220 performs character substitution of the following characters:
1221 \label{character substitution}
1228 %C = If the job is a Cloned job (Only on director side)
1229 %d = Daemon's name (Such as host-dir or host-fd)
1230 %D = Director's name (Also valid on file daemon)
1231 %e = Job Exit Status
1232 %f = Job FileSet (Only on director side)
1239 %p = Pool name (Only on director side)
1240 %P = Current PID process
1242 %t = Job type (Backup, ...)
1243 %v = Volume name (Only on director side)
1244 %w = Storage name (Only on director side)
1245 %x = Spooling enabled? ("yes" or "no")
1250 Some character substitutions are not available in all situations. The Job Exit
1251 Status code \%e edits the following values:
1254 \index[dir]{Exit Status}
1261 \item Unknown term code
1264 Thus if you edit it on a command line, you will need to enclose
1265 it within some sort of quotes.
1267 \label{Director:Job:End}
1269 You can use these following shortcuts:\\
1271 \LTXtable{0.95\linewidth}{table_runscriptshortcuts}
1277 Command = "/etc/init.d/apache stop"
1283 Command = "/etc/init.d/apache start"
1287 {\bf Notes about ClientRunBeforeJob}
1289 For compatibility reasons, with this shortcut, the command is executed
1290 directly when the client recieve it. And if the command is in error, other
1291 remote runscripts will be discarded. To be sure that all commands will be
1292 sent and executed, you have to use RunScript syntax.
1294 {\bf Special Windows Considerations}
1296 You can run scripts just after snapshots initializations with
1297 \textsl{AfterVSS} keyword.
1299 In addition, for a Windows client, please take
1300 note that you must ensure a correct path to your script. The script or
1301 program can be a .com, .exe or a .bat file. If you just put the program
1302 name in then Bacula will search using the same rules that cmd.exe uses
1303 (current directory, Bacula bin directory, and PATH). It will even try the
1304 different extensions in the same order as cmd.exe.
1305 The command can be anything that cmd.exe or command.com will recognize
1306 as an executable file.
1308 However, if you have slashes in the program name then Bacula figures you
1309 are fully specifying the name, so you must also explicitly add the three
1310 character extension.
1312 The command is run in a Win32 environment, so Unix like commands will not
1313 work unless you have installed and properly configured Cygwin in addition
1314 to and separately from Bacula.
1316 The System \%Path\% will be searched for the command. (under the
1317 environment variable dialog you have have both System Environment and
1318 User Environment, we believe that only the System environment will be
1319 available to bacula-fd, if it is running as a service.)
1321 System environment variables can be referenced with \%var\% and
1322 used as either part of the command name or arguments.
1324 So if you have a script in the Bacula\\bin directory then the following lines
1329 Client Run Before Job = systemstate
1331 Client Run Before Job = systemstate.bat
1333 Client Run Before Job = "systemstate"
1335 Client Run Before Job = "systemstate.bat"
1337 ClientRunBeforeJob = "\"C:/Program Files/Bacula/systemstate.bat\""
1341 The outer set of quotes is removed when the configuration file is parsed.
1342 You need to escape the inner quotes so that they are there when the code
1343 that parses the command line for execution runs so it can tell what the
1349 ClientRunBeforeJob = "\"C:/Program Files/Software
1350 Vendor/Executable\" /arg1 /arg2 \"foo bar\""
1354 The special characters
1358 will need to be quoted,
1359 if they are part of a filename or argument.
1361 If someone is logged in, a blank ``command'' window running the commands
1362 will be present during the execution of the command.
1364 Some Suggestions from Phil Stracchino for running on Win32 machines with
1365 the native Win32 File daemon:
1368 \item You might want the ClientRunBeforeJob directive to specify a .bat
1369 file which runs the actual client-side commands, rather than trying
1370 to run (for example) regedit /e directly.
1371 \item The batch file should explicitly 'exit 0' on successful completion.
1372 \item The path to the batch file should be specified in Unix form:
1374 ClientRunBeforeJob = "c:/bacula/bin/systemstate.bat"
1376 rather than DOS/Windows form:
1378 ClientRunBeforeJob =
1380 "c:\textbackslash{}bacula\textbackslash{}bin\textbackslash{}systemstate.bat"
1384 For Win32, please note that there are certain limitations:
1386 ClientRunBeforeJob = "C:/Program Files/Bacula/bin/pre-exec.bat"
1388 Lines like the above do not work because there are limitations of
1389 cmd.exe that is used to execute the command.
1390 Bacula prefixes the string you supply with {\bf cmd.exe /c }. To test that
1391 your command works you should type {\bf cmd /c "C:/Program Files/test.exe"} at a
1392 cmd prompt and see what happens. Once the command is correct insert a
1393 backslash (\textbackslash{}) before each double quote ("), and
1394 then put quotes around the whole thing when putting it in
1395 the director's .conf file. You either need to have only one set of quotes
1396 or else use the short name and don't put quotes around the command path.
1398 Below is the output from cmd's help as it relates to the command line
1399 passed to the /c option.
1402 If /C or /K is specified, then the remainder of the command line after
1403 the switch is processed as a command line, where the following logic is
1404 used to process quote (") characters:
1408 If all of the following conditions are met, then quote characters
1409 on the command line are preserved:
1412 \item exactly two quote characters.
1413 \item no special characters between the two quote characters,
1414 where special is one of:
1418 \item there are one or more whitespace characters between the
1419 the two quote characters.
1420 \item the string between the two quote characters is the name
1421 of an executable file.
1424 \item Otherwise, old behavior is to see if the first character is
1425 a quote character and if so, strip the leading character and
1426 remove the last quote character on the command line, preserving
1427 any text after the last quote character.
1432 The following example of the use of the Client Run Before Job directive was
1433 submitted by a user:\\
1434 You could write a shell script to back up a DB2 database to a FIFO. The shell
1444 db2 BACKUP DATABASE mercuryd TO $DIR/dbpipe WITHOUT PROMPTING &
1449 The following line in the Job resource in the bacula-dir.conf file:
1452 Client Run Before Job = "su - mercuryd -c \"/u01/mercuryd/backupdb.sh '%t'
1457 When the job is run, you will get messages from the output of the script
1458 stating that the backup has started. Even though the command being run is
1459 backgrounded with \&, the job will block until the ``db2 BACKUP DATABASE''
1460 command, thus the backup stalls.
1462 To remedy this situation, the ``db2 BACKUP DATABASE'' line should be changed to
1467 db2 BACKUP DATABASE mercuryd TO $DIR/dbpipe WITHOUT PROMPTING > $DIR/backup.log
1472 It is important to redirect the input and outputs of a backgrounded command to
1473 /dev/null to prevent the script from blocking.

1480 The specified {\bf command} is run as an external program prior to running the
1481 current Job. This directive is not required, but if it is defined, and if the
1482 exit code of the program run is non-zero, the current Bacula job will be
1486 Run Before Job = "echo test"
1488 it's equivalent to :
1491 Command = "echo test"
1497 Lutz Kittler has pointed out that using the RunBeforeJob directive can be a
1498 simple way to modify your schedules during a holiday. For example, suppose
1499 that you normally do Full backups on Fridays, but Thursday and Friday are
1500 holidays. To avoid having to change tapes between Thursday and Friday when
1501 no one is in the office, you can create a RunBeforeJob that returns a
1502 non-zero status on Thursday and zero on all other days. That way, the
1503 Thursday job will not run, and on Friday the tape you inserted on Wednesday
1504 before leaving will be used.

1512 directive is not required. If the exit code of the program run is
1513 non-zero, Bacula will print a warning message. Before submitting the

1573 If this directive is set to {\bf yes} (default no), and Bacula detects that
1574 a previous job at a higher level (i.e. Full or Differential) has failed,
1575 the current job level will be upgraded to the higher level. This is
1576 particularly useful for Laptops where they may often be unreachable, and if
1577 a prior Full save has failed, you wish the very next backup to be a Full
1578 save rather than whatever level it is started as.
1580 There are several points that must be taken into account when using this
1581 directive: first, a failed job is defined as one that has not terminated
1582 normally, which includes any running job of the same name (you need to
1583 ensure that two jobs of the same name do not run simultaneously);
1584 secondly, the {\bf Ignore FileSet Changes} directive is not considered

1593 If this directive is set to {\bf yes} (default no), the Storage daemon will
1594 be requested to spool the data for this Job to disk rather than write it
1595 directly to the Volume (normally a tape).
1597 Thus the data is written in large blocks to the Volume rather than small
1598 blocks. This directive is particularly useful when running multiple
1599 simultaneous backups to tape. Once all the data arrives or the spool
1600 files' maximum sizes are reached, the data will be despooled and written
1603 Spooling data prevents interleaving date from several job and reduces or
1604 eliminates tape drive stop and start commonly known as ``shoe-shine''.
1606 We don't recommend using this option if you are writing to a disk file
1607 using this option will probably just slow down the backup jobs.

1627 The default is set to {\bf no}, which means that the File attributes are
1628 sent by the Storage daemon to the Director as they are stored on tape.
1629 However, if you want to avoid the possibility that database updates will
1630 slow down writing to the tape, you may want to set the value to {\bf
1631 yes}, in which case the Storage daemon will buffer the File attributes
1632 and Storage coordinates to a temporary file in the Working Directory,
1633 then when writing the Job data to the tape is completed, the attributes
1634 and storage coordinates will be sent to the Director.

1808 A duplicate job in the sense we use it here means a second or subsequent job
1809 with the same name starts. This happens most frequently when the first job
1810 runs longer than expected because no tapes are available.
1812 If this directive is enabled duplicate jobs will be run. If
1813 the directive is set to {\bf no} (default) then only one job of a given name
1814 may run at one time, and the action that Bacula takes to ensure only
1815 one job runs is determined by the other directives (see below).
1817 If {\bf Allow Duplicate Jobs} is set to {\bf no} and two jobs
1818 are present and none of the three directives given below permit
1819 cancelling a job, then the current job (the second one started)

1835 jobs the one with the highest level. For example, it will cancel a
1836 previous Incremental to run a Full backup. It works only for Backup

1866 \index[dir]{Directive!Run}
1867 \index[dir]{Clone a Job}
1868 The Run directive (not to be confused with the Run option in a
1869 Schedule) allows you to start other jobs or to clone jobs. By using the
1870 cloning keywords (see below), you can backup
1871 the same data (or almost the same data) to two or more drives
1872 at the same time. The {\bf job-name} is normally the same name
1873 as the current Job resource (thus creating a clone). However, it
1874 may be any Job name, so one job may start other related jobs.
1876 The part after the equal sign must be enclosed in double quotes,
1877 and can contain any string or set of options (overrides) that you
1878 can specify when entering the Run command from the console. For
1879 example {\bf storage=DDS-4 \ldots{}}. In addition, there are two special
1880 keywords that permit you to clone the current job. They are {\bf level=\%l}
1881 and {\bf since=\%s}. The \%l in the level keyword permits
1882 entering the actual level of the current job and the \%s in the since
1883 keyword permits putting the same time for comparison as used on the
1884 current job. Note, in the case of the since keyword, the \%s must be
1885 enclosed in double quotes, and thus they must be preceded by a backslash
1886 since they are already inside quotes. For example:
1889 run = "Nightly-backup level=%l since=\"%s\" storage=DDS-4"
1892 A cloned job will not start additional clones, so it is not
1893 possible to recurse.
1895 Please note that all cloned jobs, as specified in the Run directives are
1896 submitted for running before the original job is run (while it is being
1897 initialized). This means that any clone job will actually start before
1898 the original job, and may even block the original job from starting
1899 until the original job finishes unless you allow multiple simultaneous
1900 jobs. Even if you set a lower priority on the clone job, if no other
1901 jobs are running, it will start before the original job.
1903 If you are trying to prioritize jobs by using the clone feature (Run
1904 directive), you will find it much easier to do using a RunScript
1905 resource, or a RunBeforeJob directive.
1908 \label{Director:Job:Priority}
1909 \item [Priority = \lt{}number\gt{}]
1910 \index[dir]{Priority}
1911 \index[dir]{Directive!Priority}
1912 This directive permits you to control the order in which your jobs will
1913 be run by specifying a positive non-zero number. The higher the number,
1914 the lower the job priority. Assuming you are not running concurrent jobs,
1915 all queued jobs of priority 1 will run before queued jobs of priority 2
1916 and so on, regardless of the original scheduling order.
1918 The priority only affects waiting jobs that are queued to run, not jobs
1919 that are already running. If one or more jobs of priority 2 are already
1920 running, and a new job is scheduled with priority 1, the currently
1921 running priority 2 jobs must complete before the priority 1 job is
1922 run, unless Allow Mixed Priority is set.
1924 The default priority is 10.
1926 If you want to run concurrent jobs you should
1927 keep these points in mind:
1930 \item See \bsysxrlink{Running Concurrent Jobs}{ConcurrentJobs}{problems}{section} on how to setup
1931 concurrent jobs in the \problemsman{}.
1933 \item Bacula concurrently runs jobs of only one priority at a time. It
1934 will not simultaneously run a priority 1 and a priority 2 job.
1936 \item If Bacula is running a priority 2 job and a new priority 1 job is
1937 scheduled, it will wait until the running priority 2 job terminates even
1938 if the Maximum Concurrent Jobs settings would otherwise allow two jobs
1939 to run simultaneously.
1941 \item Suppose that bacula is running a priority 2 job and a new priority 1
1942 job is scheduled and queued waiting for the running priority 2 job to
1943 terminate. If you then start a second priority 2 job, the waiting
1944 priority 1 job will prevent the new priority 2 job from running
1945 concurrently with the running priority 2 job. That is: as long as there
1946 is a higher priority job waiting to run, no new lower priority jobs will
1947 start even if the Maximum Concurrent Jobs settings would normally allow
1948 them to run. This ensures that higher priority jobs will be run as soon
1952 If you have several jobs of different priority, it may not best to start
1953 them at exactly the same time, because Bacula must examine them one at a
1954 time. If by Bacula starts a lower priority job first, then it will run
1955 before your high priority jobs. If you experience this problem, you may
1956 avoid it by starting any higher priority jobs a few seconds before lower
1957 priority ones. This insures that Bacula will examine the jobs in the
1958 correct order, and that your priority scheme will be respected.

1962 \item [Allow Mixed Priority = \lt{}yes\vb{}no\gt{}]
1963 \index[dir]{Allow Mixed Priority}
1964 This directive is only implemented in version 2.5 and later. When
1965 set to {\bf yes} (default {\bf no}), this job may run even if lower
1966 priority jobs are already running. This means a high priority job
1967 will not have to wait for other jobs to finish before starting.
1968 The scheduler will only mix priorities when all running jobs have
1971 Note that only higher priority jobs will start early. Suppose the
1972 director will allow two concurrent jobs, and that two jobs with
1973 priority 10 are running, with two more in the queue. If a job with
1974 priority 5 is added to the queue, it will be run as soon as one of
1975 the running jobs finishes. However, new priority 10 jobs will not
1976 be run until the priority 5 job has finished.

1983 This directive is only implemented in version 1.37 and later.
1984 If this directive is set to {\bf yes} (default {\bf no}), a new part file
1985 will be created after the job is finished.
1987 It should be set to {\bf yes} when writing to devices that require mount
1988 (for example DVD), so you are sure that the current part, containing
1989 this job's data, is written to the device, and that no data is left in
1990 the temporary file on the hard disk. However, on some media, like DVD+R
1991 and DVD-R, a lot of space (about 10Mb) is lost every time a part is
1992 written. So, if you run several jobs each after another, you could set
1993 this directive to {\bf no} for all jobs, except the last one, to avoid
1994 wasting too much space, but to ensure that the data is written to the
1995 medium when all jobs are finished.
1997 This directive is ignored with tape and FIFO devices.

2024 The JobDefs resource permits all the same directives that can appear in a Job
2025 resource. However, a JobDefs resource does not create a Job, rather it can be
2026 referenced within a Job to provide defaults for that Job. This permits you to
2027 concisely define several nearly identical Jobs, each one referencing a JobDefs
2028 resource which contains the defaults. Only the changes from the defaults need to
2029 be mentioned in each Job.

2032 \section{The Schedule Resource}
2033 \index[general]{Resource!Schedule}
2034 \index[general]{Schedule Resource}
2036 The Schedule resource provides a means of automatically scheduling a Job as
2037 well as the ability to override the default Level, Pool, Storage and Messages
2038 resources. If a Schedule resource is not referenced in a Job, the Job can only
2039 be run manually. In general, you specify an action to be taken and when.
2044 \index[dir]{Schedule}
2045 \index[dir]{Directive!Schedule}
2046 Start of the Schedule directives. No {\bf Schedule} resource is
2047 required, but you will need at least one if you want Jobs to be
2048 automatically started.
2050 \label{Director:Schedule:Name}
2051 \item [Name = \lt{}name\gt{}]
2053 \index[dir]{Directive!Name}

2056 \label{Director:Schedule:Run}
2057 \item [Run = \lt{}Job-overrides\gt{} \lt{}Date-time-specification\gt{}]
2059 \index[dir]{Directive!Run}
2060 The Run directive defines when a Job is to be run, and what overrides if
2061 any to apply. You may specify multiple {\bf run} directives within a
2062 {\bf Schedule} resource. If you do, they will all be applied (i.e.
2063 multiple schedules). If you have two {\bf Run} directives that start at
2064 the same time, two Jobs will start at the same time (well, within one
2065 second of each other).
2067 The {\bf Job-overrides} permit overriding the Level, the Storage, the
2068 Messages, and the Pool specifications provided in the Job resource. In
2069 addition, the FullPool, the IncrementalPool, and the DifferentialPool
2070 specifications permit overriding the Pool specification according to
2071 what backup Job Level is in effect.
2073 By the use of overrides, you may customize a particular Job. For
2074 example, you may specify a Messages override for your Incremental
2075 backups that outputs messages to a log file, but for your weekly or
2076 monthly Full backups, you may send the output by email by using a
2077 different Messages override.
2079 {\bf Job-overrides} are specified as: {\bf keyword=value} where the
2080 keyword is Level, Storage, Messages, Pool, FullPool, DifferentialPool,
2081 or IncrementalPool, and the {\bf value} is as defined on the respective
2082 directive formats for the Job resource. You may specify multiple {\bf
2083 Job-overrides} on one {\bf Run} directive by separating them with one or
2084 more spaces or by separating them with a trailing comma. For example:
2086 \label{Director:Schedule:End}
2091 \index[dir]{Directive!Level}
2092 is all files in the FileSet whether or not they have changed.
2094 \item [Level=Incremental]
2096 \index[dir]{Directive!Level}
2097 is all files that have changed since the last backup.
2101 \index[dir]{Directive!Pool}
2102 specifies to use the Pool named {\bf Weekly}.
2104 \item [Storage=DLT\_Drive]
2105 \index[dir]{Storage}
2106 \index[dir]{Directive!Storage}
2107 specifies to use {\bf DLT\_Drive} for the storage device.
2109 \item [Messages=Verbose]
2110 \index[dir]{Messages}
2111 \index[dir]{Directive!Messages}
2112 specifies to use the {\bf Verbose} message resource for the Job.
2114 \item [FullPool=Full]
2115 \index[dir]{FullPool}
2116 \index[dir]{Directive!FullPool}
2117 specifies to use the Pool named {\bf Full} if the job is a full backup, or
2119 upgraded from another type to a full backup.
2121 \item [DifferentialPool=Differential]
2122 \index[dir]{DifferentialPool}
2123 \index[dir]{Directive!DifferentialPool}
2124 specifies to use the Pool named {\bf Differential} if the job is a
2125 differential backup.
2127 \item [IncrementalPool=Incremental]
2128 \index[dir]{IncrementalPool}
2129 \index[dir]{Directive!IncrementalPool}
2130 specifies to use the Pool named {\bf Incremental} if the job is an
2134 \item [WritePartAfterJob=yes\vb{}no]
2135 \index[dir]{WritePartAfterJob}
2136 \index[dir]{Directive!WritePartAfterJob}
2137 tells Bacula to request the Storage daemon to write the current part
2138 file to the device when the job is finished (see \ilink{Write Part After
2139 Job directive in the Job resource}{WritePartAfterJob}). Please note,
2140 this directive is implemented only in version 1.37 and later. The
2141 default is yes. We strongly recommend that you keep this set to yes
2142 otherwise, when the last job has finished one part will remain in the
2143 spool file and restore may or may not work.
2147 {\bf Date-time-specification} determines when the Job is to be run. The
2148 specification is a repetition, and as a default Bacula is set to run a job at
2149 the beginning of the hour of every hour of every day of every week of every
2150 month of every year. This is not normally what you want, so you must specify
2151 or limit when you want the job to run. Any specification given is assumed to
2152 be repetitive in nature and will serve to override or limit the default
2153 repetition. This is done by specifying masks or times for the hour, day of the
2154 month, day of the week, week of the month, week of the year, and month when
2155 you want the job to run. By specifying one or more of the above, you can
2156 define a schedule to repeat at almost any frequency you want.
2158 Basically, you must supply a {\bf month}, {\bf day}, {\bf hour}, and {\bf
2159 minute} the Job is to be run. Of these four items to be specified, {\bf day}
2160 is special in that you may either specify a day of the month such as 1, 2,
2161 \ldots{} 31, or you may specify a day of the week such as Monday, Tuesday, \ldots{}
2162 Sunday. Finally, you may also specify a week qualifier to restrict the
2163 schedule to the first, second, third, fourth, or fifth week of the month.
2165 For example, if you specify only a day of the week, such as {\bf Tuesday} the
2166 Job will be run every hour of every Tuesday of every Month. That is the {\bf
2167 month} and {\bf hour} remain set to the defaults of every month and all
2170 Note, by default with no other specification, your job will run at the
2171 beginning of every hour. If you wish your job to run more than once in any
2172 given hour, you will need to specify multiple {\bf run} specifications each
2173 with a different minute.
2175 The date/time to run the Job can be specified in the following way in
2182 <week-keyword> = 1st | 2nd | 3rd | 4th | 5th | first |
2183 second | third | fourth | fifth
2184 <wday-keyword> = sun | mon | tue | wed | thu | fri | sat |

2209 <wday-range> = <wday-keyword>-<wday-keyword>
2210 <range> = <day-range> | <month-range> |
2212 <date> = <date-keyword> | <day> | <range>
2213 <date-spec> = <date> | <date-spec>
2214 <day-spec> = <day> | <wday-keyword> |
2215 <day> | <wday-range> |
2216 <week-keyword> <wday-keyword> |
2217 <week-keyword> <wday-range> |
2219 <month-spec> = <month-keyword> | <month-range> |
2221 <date-time-spec> = <month-spec> <day-spec> <time-spec>
2227 Note, the Week of Year specification wnn follows the ISO standard definition
2228 of the week of the year, where Week 1 is the week in which the first Thursday
2229 of the year occurs, or alternatively, the week which contains the 4th of
2230 January. Weeks are numbered w01 to w53. w00 for Bacula is the week that
2231 precedes the first ISO week (i.e. has the first few days of the year if any
2232 occur before Thursday). w00 is not defined by the ISO specification. A week
2233 starts with Monday and ends with Sunday.
2235 According to the NIST (US National Institute of Standards and Technology),
2236 12am and 12pm are ambiguous and can be defined to anything. However,
2237 12:01am is the same as 00:01 and 12:01pm is the same as 12:01, so Bacula
2238 defines 12am as 00:00 (midnight) and 12pm as 12:00 (noon). You can avoid
2239 this abiguity (confusion) by using 24 hour time specifications (i.e. no
2240 am/pm). This is the definition in Bacula version 2.0.3 and later.
2242 An example schedule resource that is named {\bf WeeklyCycle} and runs a job
2243 with level full each Sunday at 2:05am and an incremental job Monday through
2244 Saturday at 2:05am is:
2249 Name = "WeeklyCycle"
2250 Run = Level=Full sun at 2:05
2251 Run = Level=Incremental mon-sat at 2:05
2256 An example of a possible monthly cycle is as follows:
2261 Name = "MonthlyCycle"
2262 Run = Level=Full Pool=Monthly 1st sun at 2:05
2263 Run = Level=Differential 2nd-5th sun at 2:05
2264 Run = Level=Incremental Pool=Daily mon-sat at 2:05
2269 The first of every month:
2275 Run = Level=Full on 1 at 2:05
2276 Run = Level=Incremental on 2-31 at 2:05
2287 Run = Level=Full hourly at 0:05
2288 Run = Level=Full hourly at 0:15
2289 Run = Level=Full hourly at 0:25
2290 Run = Level=Full hourly at 0:35
2291 Run = Level=Full hourly at 0:45
2292 Run = Level=Full hourly at 0:55
2297 \section{Technical Notes on Schedules}
2298 \index[general]{Schedules!Technical Notes on}
2299 \index[general]{Technical Notes on Schedules}
2301 Internally Bacula keeps a schedule as a bit mask. There are six masks and a
2302 minute field to each schedule. The masks are hour, day of the month (mday),
2303 month, day of the week (wday), week of the month (wom), and week of the year
2304 (woy). The schedule is initialized to have the bits of each of these masks
2305 set, which means that at the beginning of every hour, the job will run. When
2306 you specify a month for the first time, the mask will be cleared and the bit
2307 corresponding to your selected month will be selected. If you specify a second
2308 month, the bit corresponding to it will also be added to the mask. Thus when
2309 Bacula checks the masks to see if the bits are set corresponding to the
2310 current time, your job will run only in the two months you have set. Likewise,
2311 if you set a time (hour), the hour mask will be cleared, and the hour you
2312 specify will be set in the bit mask and the minutes will be stored in the
2315 For any schedule you have defined, you can see how these bits are set by doing
2316 a {\bf show schedules} command in the Console program. Please note that the
2317 bit mask is zero based, and Sunday is the first day of the week (bit zero).

2366 This specifies the name of the catalog resource to be used for this Client.
2367 This directive is required.

2370 \item [Password = \lt{}password\gt{}]
2371 \index[dir]{Password}
2372 \index[dir]{Directive!Password}
2373 This is the password to be used when establishing a connection with the File
2374 services, so the Client configuration file on the machine to be backed up
2375 must have the same password defined for this Director. This directive is
2376 required. If you have either {\bf /dev/random} {\bf bc} on your machine,
2377 Bacula will generate a random password during the configuration process,
2378 otherwise it will be left blank.
2380 The password is plain text. It is not generated through any special
2381 process, but it is preferable for security reasons to make the text

2387 \item [File Retention = \lt{}time-period-specification\gt{}]
2388 \index[dir]{File Retention}
2389 \index[dir]{Directive!File Retention}
2390 The File Retention directive defines the length of time that Bacula will
2391 keep File records in the Catalog database after the End time of the
2392 Job corresponding to the File records.
2393 When this time period expires, and if
2394 {\bf AutoPrune} is set to {\bf yes} Bacula will prune (remove) File records
2395 that are older than the specified File Retention period. Note, this affects
2396 only records in the catalog database. It does not affect your archive
2399 File records may actually be retained for a shorter period than you specify
2400 on this directive if you specify either a shorter {\bf Job Retention} or a
2401 shorter {\bf Volume Retention} period. The shortest retention period of the
2402 three takes precedence. The time may be expressed in seconds, minutes,
2403 hours, days, weeks, months, quarters, or years. See the
2404 \ilink{ Configuration chapter}{Time} of this manual for
2405 additional details of time specification.
2407 The default is 60 days.

2411 \item [Job Retention = \lt{}time-period-specification\gt{}]
2412 \index[dir]{Job Retention}
2413 \index[dir]{Directive!Job Retention}
2414 The Job Retention directive defines the length of time that Bacula will keep
2415 Job records in the Catalog database after the Job End time. When
2416 this time period expires, and if {\bf AutoPrune} is set to {\bf yes}
2417 Bacula will prune (remove) Job records that are older than the specified
2418 File Retention period. As with the other retention periods, this
2419 affects only records in the catalog and not data in your archive backup.
2421 If a Job record is selected for pruning, all associated File and JobMedia
2422 records will also be pruned regardless of the File Retention period set.
2423 As a consequence, you normally will set the File retention period to be
2424 less than the Job retention period. The Job retention period can actually
2425 be less than the value you specify here if you set the {\bf Volume
2426 Retention} directive in the Pool resource to a smaller duration. This is
2427 because the Job retention period and the Volume retention period are
2428 independently applied, so the smaller of the two takes precedence.
2430 The Job retention period is specified as seconds, minutes, hours, days,
2431 weeks, months, quarters, or years. See the
2432 \ilink{ Configuration chapter}{Time} of this manual for
2433 additional details of time specification.
2435 The default is 180 days.

2441 \index[dir]{Directive!AutoPrune}
2442 If AutoPrune is set to {\bf yes} (default), Bacula (version 1.20 or greater)
2443 will automatically apply the File retention period and the Job retention
2444 period for the Client at the end of the Job. If you set {\bf AutoPrune = no},
2445 pruning will not be done, and your Catalog will grow in size each time you
2446 run a Job. Pruning affects only information in the catalog and not data
2447 stored in the backup archives (on Volumes).

2455 with the same name as the resource in which it appears. Any other
2456 restrictions on the maximum concurrent jobs such as in the Director, Job, or

2566 This is the password to be used when establishing a connection with the

2568 resource of the Storage daemon's configuration file. This directive is
2569 required. If you have either {\bf /dev/random} {\bf bc} on your machine,
2570 Bacula will generate a random password during the configuration process,
2571 otherwise it will be left blank.
2573 The password is plain text. It is not generated through any special

2576 \label{Director:Storage:Device}
2577 \item [Device = \lt{}device-name\gt{}]
2579 \index[dir]{Directive!Device}
2580 This directive specifies the Storage daemon's name of the device
2581 resource to be used for the storage. If you are using an Autochanger,
2582 the name specified here should be the name of the Storage daemon's
2583 Autochanger resource rather than the name of an individual device. This
2584 name is not the physical device name, but the logical device name as
2585 defined on the {\bf Name} directive contained in the {\bf Device} or the
2586 {\bf Autochanger} resource definition of the {\bf Storage daemon}
2587 configuration file. You can specify any name you would like (even the
2588 device name if you prefer) up to a maximum of 127 characters in length.
2589 The physical device name associated with this device is specified in the
2590 {\bf Storage daemon} configuration file (as {\bf Archive Device}).
2591 Please take care not to define two different Storage resource directives
2592 in the Director that point to the same Device in the Storage daemon.
2593 Doing so may cause the Storage daemon to block (or hang) attempting to
2594 open the same device that is already open. This directive is required.
2597 \label{Director:Storage:MediaType}
2598 \item [Media Type = \lt{}MediaType\gt{}]
2599 \index[dir]{Media Type}
2600 \index[dir]{Directive!Media Type}
2601 This directive specifies the Media Type to be used to store the data.
2602 This is an arbitrary string of characters up to 127 maximum that you
2603 define. It can be anything you want. However, it is best to make it
2604 descriptive of the storage media (e.g. File, DAT, ``HP DLT8000'', 8mm,
2605 \ldots{}). In addition, it is essential that you make the {\bf Media Type}
2606 specification unique for each storage media type. If you have two DDS-4
2607 drives that have incompatible formats, or if you have a DDS-4 drive and
2608 a DDS-4 autochanger, you almost certainly should specify different {\bf
2609 Media Types}. During a restore, assuming a {\bf DDS-4} Media Type is
2610 associated with the Job, Bacula can decide to use any Storage daemon
2611 that supports Media Type {\bf DDS-4} and on any drive that supports it.
2613 If you are writing to disk Volumes, you must make doubly sure that each
2614 Device resource defined in the Storage daemon (and hence in the
2615 Director's conf file) has a unique media type. Otherwise for Bacula
2616 versions 1.38 and older, your restores may not work because Bacula
2617 will assume that you can mount any Media Type with the same name on
2618 any Device associated with that Media Type. This is possible with
2619 tape drives, but with disk drives, unless you are very clever you
2620 cannot mount a Volume in any directory -- this can be done by creating
2621 an appropriate soft link.
2623 Currently Bacula permits only a single Media Type per Storage
2624 and Device definition. Consequently, if
2625 you have a drive that supports more than one Media Type, you can
2626 give a unique string to Volumes with different intrinsic Media
2627 Type (Media Type = DDS-3-4 for DDS-3 and DDS-4 types), but then
2628 those volumes will only be mounted on drives indicated with the
2629 dual type (DDS-3-4).
2631 If you want to tie Bacula to using a single Storage daemon or drive, you
2632 must specify a unique Media Type for that drive. This is an important
2633 point that should be carefully understood. Note, this applies equally
2634 to Disk Volumes. If you define more than one disk Device resource in
2635 your Storage daemon's conf file, the Volumes on those two devices are in
2636 fact incompatible because one can not be mounted on the other device
2637 since they are found in different directories. For this reason, you
2638 probably should use two different Media Types for your two disk Devices
2639 (even though you might think of them as both being File types). You can
2640 find more on this subject in the \ilink{Basic Volume
2641 Management}{DiskChapter} chapter of this manual.
2643 The {\bf MediaType} specified in the Director's Storage resource, {\bf
2644 must} correspond to the {\bf Media Type} specified in the {\bf Device}
2645 resource of the {\bf Storage daemon} configuration file. This directive
2646 is required, and it is used by the Director and the Storage daemon to
2647 ensure that a Volume automatically selected from the Pool corresponds to
2648 the physical device. If a Storage daemon handles multiple devices (e.g.
2649 will write to various file Volumes on different partitions), this
2650 directive allows you to specify exactly which device.
2652 As mentioned above, the value specified in the Director's Storage
2653 resource must agree with the value specified in the Device resource in
2654 the {\bf Storage daemon's} configuration file. It is also an additional
2655 check so that you don't try to write data for a DLT onto an 8mm device.

2659 \item [Autochanger = \lt{}yes\vb{}no\gt{}]
2660 \index[dir]{Autochanger}
2661 \index[dir]{Directive!Autochanger}
2662 If you specify {\bf yes} for this command (the default is {\bf no}),
2663 when you use the {\bf label} command or the {\bf add} command to create
2664 a new Volume, {\bf Bacula} will also request the Autochanger Slot
2665 number. This simplifies creating database entries for Volumes in an
2666 autochanger. If you forget to specify the Slot, the autochanger will
2667 not be used. However, you may modify the Slot associated with a Volume
2668 at any time by using the {\bf update volume} or {\bf update slots}
2669 command in the console program. When {\bf autochanger} is enabled, the
2670 algorithm used by Bacula to search for available volumes will be
2671 modified to consider only Volumes that are known to be in the
2672 autochanger's magazine. If no {\bf in changer} volume is found, Bacula
2673 will attempt recycling, pruning, \ldots{}, and if still no volume is found,
2674 Bacula will search for any volume whether or not in the magazine. By
2675 privileging in changer volumes, this procedure minimizes operator
2676 intervention. The default is {\bf no}.
2678 For the autochanger to be used, you must also specify {\bf Autochanger =
2679 yes} in the \ilink{Device Resource}{Autochanger} in the Storage daemon's
2680 configuration file as well as other important Storage daemon
2681 configuration information. Please consult the \ilink{Using
2682 Autochangers}{AutochangersChapter} manual of this chapter for the
2683 details of using autochangers.

2694 default is set to 1, but you may set it to a larger number. However, if
2695 you set the Storage daemon's number of concurrent jobs greater than one,
2696 we recommend that you read the waring documented under \ilink{Maximum

2743 \section{The Pool Resource}
2744 \index[general]{Resource!Pool}
2745 \index[general]{Pool Resource}
2747 The Pool resource defines the set of storage Volumes (tapes or files) to be
2748 used by Bacula to write the data. By configuring different Pools, you can
2749 determine which set of Volumes (media) receives the backup data. This permits,
2750 for example, to store all full backup data on one set of Volumes and all
2751 incremental backups on another set of Volumes. Alternatively, you could assign
2752 a different set of Volumes to each machine that you backup. This is most
2753 easily done by defining multiple Pools.
2755 Another important aspect of a Pool is that it contains the default attributes
2756 (Maximum Jobs, Retention Period, Recycle flag, \ldots{}) that will be given to a
2757 Volume when it is created. This avoids the need for you to answer a large
2758 number of questions when labeling a new Volume. Each of these attributes can
2759 later be changed on a Volume by Volume basis using the {\bf update} command in
2760 the console program. Note that you must explicitly specify which Pool Bacula
2761 is to use with each Job. Bacula will not automatically search for the correct
2764 Most often in Bacula installations all backups for all machines (Clients) go
2765 to a single set of Volumes. In this case, you will probably only use the {\bf
2766 Default} Pool. If your backup strategy calls for you to mount a different tape
2767 each day, you will probably want to define a separate Pool for each day. For
2768 more information on this subject, please see the
2769 \ilink{Backup Strategies}{StrategiesChapter} chapter of this
2773 To use a Pool, there are three distinct steps. First the Pool must be defined
2774 in the Director's configuration file. Then the Pool must be written to the
2775 Catalog database. This is done automatically by the Director each time that it
2776 starts, or alternatively can be done using the {\bf create} command in the
2777 console program. Finally, if you change the Pool definition in the Director's
2778 configuration file and restart Bacula, the pool will be updated alternatively
2779 you can use the {\bf update pool} console command to refresh the database
2780 image. It is this database image rather than the Director's resource image
2781 that is used for the default Volume attributes. Note, for the pool to be
2782 automatically created or updated, it must be explicitly referenced by a Job
2785 Next the physical media must be labeled. The labeling can either be done with
2786 the {\bf label} command in the {\bf console} program or using the {\bf btape}
2787 program. The preferred method is to use the {\bf label} command in the {\bf
2790 Finally, you must add Volume names (and their attributes) to the Pool. For
2791 Volumes to be used by Bacula they must be of the same {\bf Media Type} as the
2792 archive device specified for the job (i.e. if you are going to back up to a
2793 DLT device, the Pool must have DLT volumes defined since 8mm volumes cannot be
2794 mounted on a DLT drive). The {\bf Media Type} has particular importance if you
2795 are backing up to files. When running a Job, you must explicitly specify which
2796 Pool to use. Bacula will then automatically select the next Volume to use from
2797 the Pool, but it will ensure that the {\bf Media Type} of any Volume selected
2798 from the Pool is identical to that required by the Storage resource you have
2799 specified for the Job.
2801 If you use the {\bf label} command in the console program to label the
2802 Volumes, they will automatically be added to the Pool, so this last step is
2803 not normally required.
2805 It is also possible to add Volumes to the database without explicitly labeling
2806 the physical volume. This is done with the {\bf add} console command.
2808 As previously mentioned, each time Bacula starts, it scans all the Pools
2809 associated with each Catalog, and if the database record does not already
2810 exist, it will be created from the Pool Resource definition. {\bf Bacula}
2811 probably should do an {\bf update pool} if you change the Pool definition, but
2812 currently, you must do this manually using the {\bf update pool} command in
2813 the Console program.
2815 The Pool Resource defined in the Director's configuration file
2816 (bacula-dir.conf) may contain the following directives:
2822 \index[dir]{Directive!Pool}
2823 Start of the Pool resource. There must be at least one Pool resource
2827 \label{Director:Pool:Name}
2828 \item [Name = \lt{}name\gt{}]
2830 \index[dir]{Directive!Name}
2831 The name of the pool. For most applications, you will use the default
2832 pool name {\bf Default}. This directive is required.
2835 \label{Director:Pool:MaximumVolumes}
2836 \item [Maximum Volumes = \lt{}number\gt{}]
2837 \index[dir]{Maximum Volumes}
2838 \index[dir]{Directive!Maximum Volumes}
2839 This directive specifies the maximum number of volumes (tapes or files)
2840 contained in the pool. This directive is optional, if omitted or set to
2841 zero, any number of volumes will be permitted. In general, this
2842 directive is useful for Autochangers where there is a fixed number of
2843 Volumes, or for File storage where you wish to ensure that the backups
2844 made to disk files do not become too numerous or consume too much space.
2846 \label{Director:Pool:PoolType}
2847 \item [Pool Type = \lt{}type\gt{}]
2848 \index[dir]{Pool Type}
2849 \index[dir]{Directive!Pool Type}
2850 This directive defines the pool type, which corresponds to the type of
2851 Job being run. It is required and may be one of the following:
2861 Note, only Backup is current implemented.
2863 \label{Director:Pool:Storage}
2864 \item [Storage = \lt{}storage-resource-name\gt{}]
2865 \index[dir]{Storage}
2866 \index[dir]{Directive!Storage}
2867 The Storage directive defines the name of the storage services where you
2868 want to backup the FileSet data. For additional details, see the
2869 \ilink{Storage Resource Chapter}{StorageResource} of this manual.
2870 The Storage resource may also be specified in the Job resource,
2871 but the value, if any, in the Pool resource overrides any value
2872 in the Job. This Storage resource definition is not required by either
2873 the Job resource or in the Pool, but it must be specified in
2874 one or the other. If not configuration error will result.
2876 \label{Director:Pool:UseVolumeOnce}
2877 \item [Use Volume Once = \lt{}yes\vb{}no\gt{}]
2878 \index[dir]{Use Volume Once}
2879 \index[dir]{Directive!Use Volume Once}
2880 This directive if set to {\bf yes} specifies that each volume is to be
2881 used only once. This is most useful when the Media is a file and you
2882 want a new file for each backup that is done. The default is {\bf no}
2883 (i.e. use volume any number of times). This directive will most likely
2884 be phased out (deprecated), so you are recommended to use {\bf Maximum
2885 Volume Jobs = 1} instead.
2887 The value defined by this directive in the bacula-dir.conf file is the
2888 default value used when a Volume is created. Once the volume is
2889 created, changing the value in the bacula-dir.conf file will not change
2890 what is stored for the Volume. To change the value for an existing
2891 Volume you must use the {\bf update} command in the Console.
2893 Please see the notes below under {\bf Maximum Volume Jobs} concerning
2894 using this directive with multiple simultaneous jobs.

2897 \item [Maximum Volume Jobs = \lt{}positive-integer\gt{}]
2898 \index[dir]{Maximum Volume Jobs}
2899 \index[dir]{Directive!Maximum Volume Jobs}
2900 This directive specifies the maximum number of Jobs that can be written
2901 to the Volume. If you specify zero (the default), there is no limit.
2902 Otherwise, when the number of Jobs backed up to the Volume equals {\bf
2903 positive-integer} the Volume will be marked {\bf Used}. When the Volume
2904 is marked {\bf Used} it can no longer be used for appending Jobs, much
2905 like the {\bf Full} status but it can be recycled if recycling is
2906 enabled, and thus used again. By setting {\bf MaximumVolumeJobs} to
2907 one, you get the same effect as setting {\bf UseVolumeOnce = yes}.
2909 The value defined by this directive in the bacula-dir.conf
2910 file is the default value used when a Volume is created. Once the volume is
2911 created, changing the value in the bacula-dir.conf file will not change what
2912 is stored for the Volume. To change the value for an existing Volume you
2913 must use the {\bf update} command in the Console.
2915 If you are running multiple simultaneous jobs, this directive may not
2916 work correctly because when a drive is reserved for a job, this
2917 directive is not taken into account, so multiple jobs may try to
2918 start writing to the Volume. At some point, when the Media record is
2919 updated, multiple simultaneous jobs may fail since the Volume can no

2926 This directive specifies the maximum number of files that can be written
2927 to the Volume. If you specify zero (the default), there is no limit.
2928 Otherwise, when the number of files written to the Volume equals {\bf
2929 positive-integer} the Volume will be marked {\bf Used}. When the Volume
2930 is marked {\bf Used} it can no longer be used for appending Jobs, much
2931 like the {\bf Full} status but it can be recycled if recycling is
2932 enabled and thus used again. This value is checked and the {\bf Used}
2933 status is set only at the end of a job that writes to the particular
2936 The value defined by this directive in the bacula-dir.conf file is the
2937 default value used when a Volume is created. Once the volume is
2938 created, changing the value in the bacula-dir.conf file will not change
2939 what is stored for the Volume. To change the value for an existing
2940 Volume you must use the {\bf update} command in the Console.
2942 \label{Director:Pool:MaximumVolumeBytes}
2943 \item [Maximum Volume Bytes = \lt{}size\gt{}]
2944 \index[dir]{Maximum Volume Bytes}
2945 \index[dir]{Directive!Maximum Volume Bytes}
2946 This directive specifies the maximum number of bytes that can be written
2947 to the Volume. If you specify zero (the default), there is no limit
2948 except the physical size of the Volume. Otherwise, when the number of
2949 bytes written to the Volume equals {\bf size} the Volume will be marked
2950 {\bf Used}. When the Volume is marked {\bf Used} it can no longer be
2951 used for appending Jobs, much like the {\bf Full} status but it can be
2952 recycled if recycling is enabled, and thus the Volume can be re-used
2953 after recycling. This value is checked and the {\bf Used} status set
2954 while the job is writing to the particular volume.
2956 This directive is particularly useful for restricting the size
2957 of disk volumes, and will work correctly even in the case of
2958 multiple simultaneous jobs writing to the volume.
2960 The value defined by this directive in the bacula-dir.conf file is the
2961 default value used when a Volume is created. Once the volume is
2962 created, changing the value in the bacula-dir.conf file will not change
2963 what is stored for the Volume. To change the value for an existing
2964 Volume you must use the {\bf update} command in the Console.
2966 \label{Director:Pool:VolumeUseDuration}
2967 \item [Volume Use Duration = \lt{}time-period-specification\gt{}]
2968 \index[dir]{Volume Use Duration}
2969 \index[dir]{Directive!Volume Use Duration}
2970 The Volume Use Duration directive defines the time period that the
2971 Volume can be written beginning from the time of first data write to the
2972 Volume. If the time-period specified is zero (the default), the Volume
2973 can be written indefinitely. Otherwise, the next time a job
2974 runs that wants to access this Volume, and the time period from the
2975 first write to the volume (the first Job written) exceeds the
2976 time-period-specification, the Volume will be marked {\bf Used}, which
2977 means that no more Jobs can be appended to the Volume, but it may be
2978 recycled if recycling is enabled. Using the command {\bf
2979 status dir} applies algorithms similar to running jobs, so
2980 during such a command, the Volume status may also be changed.
2982 recycled, it will be available for use again.
2984 You might use this directive, for example, if you have a Volume used for
2985 Incremental backups, and Volumes used for Weekly Full backups. Once the
2986 Full backup is done, you will want to use a different Incremental
2987 Volume. This can be accomplished by setting the Volume Use Duration for
2988 the Incremental Volume to six days. I.e. it will be used for the 6
2989 days following a Full save, then a different Incremental volume will be
2990 used. Be careful about setting the duration to short periods such as 23
2991 hours, or you might experience problems of Bacula waiting for a tape
2992 over the weekend only to complete the backups Monday morning when an
2993 operator mounts a new tape.
2995 The use duration is checked and the {\bf Used} status is set only at the
2996 end of a job that writes to the particular volume, which means that even
2997 though the use duration may have expired, the catalog entry will not be
2998 updated until the next job that uses this volume is run. This
2999 directive is not intended to be used to limit volume sizes
3000 and will not work correctly (i.e. will fail jobs) if the use
3001 duration expires while multiple simultaneous jobs are writing
3004 Please note that the value defined by this directive in the bacula-dir.conf
3005 file is the default value used when a Volume is created. Once the volume is
3006 created, changing the value in the bacula-dir.conf file will not change what
3007 is stored for the Volume. To change the value for an existing Volume you
3009 \bsysxrlink{update volume}{UpdateCommand}{console}{command} in the \consoleman{}.

3012 \item [Catalog Files = \lt{}yes\vb{}no\gt{}]
3013 \index[dir]{Catalog Files}
3014 \index[dir]{Directive!Catalog Files}
3015 This directive defines whether or not you want the names of the files
3016 that were saved to be put into the catalog. The default is {\bf yes}.
3017 The advantage of specifying {\bf Catalog Files = No} is that you will
3018 have a significantly smaller Catalog database. The disadvantage is that
3019 you will not be able to produce a Catalog listing of the files backed up
3020 for each Job (this is often called Browsing). Also, without the File
3021 entries in the catalog, you will not be able to use the Console {\bf
3022 restore} command nor any other command that references File entries.
3023 \label{PoolAutoPrune}

3026 \item [AutoPrune = \lt{}yes\vb{}no\gt{}]
3027 \index[dir]{AutoPrune}
3028 \index[dir]{Directive!AutoPrune}
3029 If AutoPrune is set to {\bf yes} (default), Bacula (version 1.20 or
3030 greater) will automatically apply the Volume Retention period when new
3031 Volume is needed and no appendable Volumes exist in the Pool. Volume
3032 pruning causes expired Jobs (older than the {\bf Volume Retention}
3033 period) to be deleted from the Catalog and permits possible recycling of
3035 \label{VolRetention}
3037 \label{Director:Pool:VolumeRetention}
3038 \item [Volume Retention = \lt{}time-period-specification\gt{}]
3039 \index[dir]{Volume Retention}
3040 \index[dir]{Directive!Volume Retention}
3041 The Volume Retention directive defines the length of time that {\bf
3042 Bacula} will keep records associated with the Volume in
3043 the Catalog database after the End time of each Job written to the
3044 Volume. When this time period expires, and if {\bf AutoPrune} is set to
3045 {\bf yes} Bacula may prune (remove) Job records that are older than the
3046 specified Volume Retention period if it is necessary to free up a
3047 Volume. Recycling will not occur until it is absolutely necessary to
3048 free up a volume (i.e. no other writable volume exists).
3049 All File records associated with pruned Jobs are also
3050 pruned. The time may be specified as seconds, minutes, hours, days,
3051 weeks, months, quarters, or years. The {\bf Volume Retention} is
3052 applied independently of the {\bf Job Retention} and the {\bf File
3053 Retention} periods defined in the Client resource. This means that all
3054 the retentions periods are applied in turn and that the shorter period
3055 is the one that effectively takes precedence. Note, that when the {\bf
3056 Volume Retention} period has been reached, and it is necessary to obtain
3057 a new volume, Bacula will prune both the Job and the File records. This
3058 pruning could also occur during a {\bf status dir} command because it
3059 uses similar algorithms for finding the next available Volume.
3061 It is important to know that when the Volume Retention period expires,
3062 Bacula does not automatically recycle a Volume. It attempts to keep the
3063 Volume data intact as long as possible before over writing the Volume.
3065 By defining multiple Pools with different Volume Retention periods, you
3066 may effectively have a set of tapes that is recycled weekly, another
3067 Pool of tapes that is recycled monthly and so on. However, one must
3068 keep in mind that if your {\bf Volume Retention} period is too short, it
3069 may prune the last valid Full backup, and hence until the next Full
3070 backup is done, you will not have a complete backup of your system, and
3071 in addition, the next Incremental or Differential backup will be
3072 promoted to a Full backup. As a consequence, the minimum {\bf Volume
3073 Retention} period should be at twice the interval of your Full backups.
3074 This means that if you do a Full backup once a month, the minimum Volume
3075 retention period should be two months.
3077 The default Volume retention period is 365 days, and either the default
3078 or the value defined by this directive in the bacula-dir.conf file is
3079 the default value used when a Volume is created. Once the volume is
3080 created, changing the value in the bacula-dir.conf file will not change
3081 what is stored for the Volume. To change the value for an existing
3082 Volume you must use the {\bf update} command in the Console.

3085 \item [Action On Purge = \lt{Truncate}]
3086 \index[dir]{actiononpurge}
3088 This directive \textbf{ActionOnPurge=Truncate} instructs Bacula to truncate the
3089 volume when it is purged with the \texttt{purge volume action=truncate}
3090 command. It is useful to prevent disk based volumes from consuming too much
3096 Action On Purge = Truncate
3101 You can schedule the truncate operation at the end of your CatalogBackup job
3102 like in this example:

3119 \index[dir]{ScrachPool}
3120 \index[dir]{Directive!ScrachPool}
3121 This directive permits to specify a dedicate \textsl{Scratch} for the
3122 current pool. This pool will replace the special pool named \textsl{Scrach}
3123 for volume selection. For more information about \textsl{Scratch} see
3124 \ilink{Scratch Pool}{TheScratchPool} section of this manual. This is useful
3125 when using multiple storage sharing the same mediatype or when you want to
3126 dedicate volumes to a particular set of pool.

3130 \item [RecyclePool = \lt{}pool-resource-name\gt{}]
3131 \index[dir]{RecyclePool}
3132 \index[dir]{Directive!RecyclePool}
3133 This directive defines to which pool
3134 the Volume will be placed (moved) when it is recycled. Without
3135 this directive, a Volume will remain in the same pool when it is
3136 recycled. With this directive, it can be moved automatically to any
3137 existing pool during a recycle. This directive is probably most
3138 useful when defined in the Scratch pool, so that volumes will
3139 be recycled back into the Scratch pool. For more on the see the
3140 \ilink{Scratch Pool}{TheScratchPool} section of this manual.
3142 Although this directive is called RecyclePool, the Volume in
3143 question is actually moved from its current pool to the one
3144 you specify on this directive when Bacula prunes the Volume and
3145 discovers that there are no records left in the catalog and hence
3146 marks it as {\bf Purged}.
3150 \label{Director:Pool:Recycle}
3151 \item [Recycle = \lt{}yes\vb{}no\gt{}]
3152 \index[dir]{Recycle}
3153 \index[dir]{Directive!Recycle}
3154 This directive specifies whether or not Purged Volumes may be recycled.
3155 If it is set to {\bf yes} (default) and Bacula needs a volume but finds
3156 none that are appendable, it will search for and recycle (reuse) Purged
3157 Volumes (i.e. volumes with all the Jobs and Files expired and thus
3158 deleted from the Catalog). If the Volume is recycled, all previous data
3159 written to that Volume will be overwritten. If Recycle is set to {\bf
3160 no}, the Volume will not be recycled, and hence, the data will remain
3161 valid. If you want to reuse (re-write) the Volume, and the recycle flag
3162 is no (0 in the catalog), you may manually set the recycle flag (update
3163 command) for a Volume to be reused.
3165 Please note that the value defined by this directive in the
3166 bacula-dir.conf file is the default value used when a Volume is created.
3167 Once the volume is created, changing the value in the bacula-dir.conf
3168 file will not change what is stored for the Volume. To change the value
3169 for an existing Volume you must use the {\bf update} command in the
3172 When all Job and File records have been pruned or purged from the
3173 catalog for a particular Volume, if that Volume is marked as
3174 Append, Full, Used, or Error, it will then be marked as Purged. Only
3175 Volumes marked as Purged will be considered to be converted to the
3176 Recycled state if the {\bf Recycle} directive is set to {\bf yes}.

3184 This directive instructs the Director to search for the oldest used
3185 Volume in the Pool when another Volume is requested by the Storage
3186 daemon and none are available. The catalog is then {\bf pruned}
3187 respecting the retention periods of all Files and Jobs written to this
3188 Volume. If all Jobs are pruned (i.e. the volume is Purged), then the
3189 Volume is recycled and will be used as the next Volume to be written.
3190 This directive respects any Job, File, or Volume retention periods that
3191 you may have specified, and as such it is {\bf much} better to use this
3192 directive than the Purge Oldest Volume.
3194 This directive can be useful if you have a fixed number of Volumes in the
3195 Pool and you want to cycle through them and you have specified the correct
3198 However, if you use this directive and have only one
3199 Volume in the Pool, you will immediately recycle your Volume if you fill

3209 If Bacula needs a new Volume, this directive instructs Bacula to Prune
3210 the volume respecting the Job and File retention periods. If all Jobs
3211 are pruned (i.e. the volume is Purged), then the Volume is recycled and
3212 will be used as the next Volume to be written. This directive respects
3213 any Job, File, or Volume retention periods that you may have specified,
3214 and thus it is {\bf much} better to use it rather than the Purge Oldest

3218 the Pool, you want to cycle through them, and you have specified
3219 retention periods that prune Volumes before you have cycled through the

3233 This directive instructs the Director to search for the oldest used
3234 Volume in the Pool when another Volume is requested by the Storage
3235 daemon and none are available. The catalog is then {\bf purged}
3236 irrespective of retention periods of all Files and Jobs written to this
3237 Volume. The Volume is then recycled and will be used as the next Volume
3238 to be written. This directive overrides any Job, File, or Volume
3239 retention periods that you may have specified.
3241 This directive can be useful if you have a fixed number of Volumes in
3242 the Pool and you want to cycle through them and reusing the oldest one
3243 when all Volumes are full, but you don't want to worry about setting
3244 proper retention periods. However, by using this option you risk losing
3247 Please be aware that {\bf Purge Oldest Volume} disregards all retention
3248 periods. If you have only a single Volume defined and you turn this
3249 variable on, that Volume will always be immediately overwritten when it
3250 fills! So at a minimum, ensure that you have a decent number of Volumes
3251 in your Pool before running any jobs. If you want retention periods to
3252 apply do not use this directive. To specify a retention period, use the
3253 {\bf Volume Retention} directive (see above).
3255 We {\bf highly} recommend against using this directive, because it is
3256 sure that some day, Bacula will recycle a Volume that contains current
3257 data. The default is {\bf no}.

3298 This directive defines a prefix string, which if it matches the
3299 beginning of a Volume name during labeling of a Volume, the Volume will
3300 be defined with the VolStatus set to {\bf Cleaning} and thus Bacula will

3310 This directive specifies the format of the labels contained in this
3311 pool. The format directive is used as a sort of template to create new
3312 Volume names during automatic Volume labeling.
3314 The {\bf format} should be specified in double quotes, and consists of
3315 letters, numbers and the special characters hyphen ({\bf -}), underscore
3316 ({\bf \_}), colon ({\bf :}), and period ({\bf .}), which are the legal
3317 characters for a Volume name. The {\bf format} should be enclosed in
3320 In addition, the format may contain a number of variable expansion
3321 characters which will be expanded by a complex algorithm allowing you to
3322 create Volume names of many different formats. In all cases, the
3323 expansion process must resolve to the set of characters noted above that
3324 are legal Volume names. Generally, these variable expansion characters
3325 begin with a dollar sign ({\bf \$}) or a left bracket ({\bf [}). If you
3326 specify variable expansion characters, you should always enclose the
3327 format with double quote characters ({\bf "}). For more details on
3328 variable expansion, please see the \bsysxrlink{Variable
3329 Expansion}{VarsChapter}{misc}{chapter} of the \miscman{}.
3331 If no variable expansion characters are found in the string, the Volume
3332 name will be formed from the {\bf format} string appended with the
3333 a unique number that increases. If you do not remove volumes from the
3334 pool, this number should be the number of volumes plus one, but this
3335 is not guaranteed. The unique number will be edited as four
3336 digits with leading zeros. For example, with a {\bf Label Format =
3337 "File-"}, the first volumes will be named {\bf File-0001}, {\bf
3338 File-0002}, \ldots{}
3340 With the exception of Job specific variables, you can test your {\bf
3341 LabelFormat} by using the \bsysxrlink{var}{var}{console}{command} in the
3344 In almost all cases, you should enclose the format specification (part
3345 after the equal sign) in double quotes. Please note that this directive
3346 is deprecated and is replaced in version 1.37 and greater with a Python
3347 script for creating volume names.
3349 \label{Director:Pool:End}
3352 In order for a Pool to be used during a Backup Job, the Pool must have at
3353 least one Volume associated with it. Volumes are created for a Pool using
3354 the {\bf label} or the {\bf add} commands in the {\bf Bacula Console},
3355 program. In addition to adding Volumes to the Pool (i.e. putting the
3356 Volume names in the Catalog database), the physical Volume must be labeled
3357 with a valid Bacula software volume label before {\bf Bacula} will accept
3358 the Volume. This will be automatically done if you use the {\bf label}
3359 command. Bacula can automatically label Volumes if instructed to do so,
3360 but this feature is not yet fully implemented.
3362 The following is an example of a valid Pool resource definition:
3374 \label{TheScratchPool}
3375 \subsection{The Scratch Pool}
3376 \index[general]{Scratch Pool}
3377 In general, you can give your Pools any name you wish, but there is one
3378 important restriction: the Pool named {\bf Scratch}, if it exists behaves
3379 like a scratch pool of Volumes in that when Bacula needs a new Volume for
3380 writing and it cannot find one, it will look in the Scratch pool, and if
3381 it finds an available Volume, it will move it out of the Scratch pool into
3382 the Pool currently being used by the job.

3390 The Catalog Resource defines what catalog to use for the current job.
3391 Currently, Bacula can only handle a single database server (SQLite, MySQL,
3392 PostgreSQL) that is defined when configuring {\bf Bacula}. However, there
3393 may be as many Catalogs (databases) defined as you wish. For example, you
3394 may want each Client to have its own Catalog database, or you may want
3395 backup jobs to use one database and verify or restore jobs to use another
3398 Since SQLite is compiled in, it always runs on the same machine
3399 as the Director and the database must be directly accessible (mounted) from
3400 the Director. However, since both MySQL and PostgreSQL are networked
3401 databases, they may reside either on the same machine as the Director
3402 or on a different machine on the network. See below for more details.
3407 \index[dir]{Catalog}
3408 \index[dir]{Directive!Catalog}
3409 Start of the Catalog resource. At least one Catalog resource must be
3413 \label{Director:Catalog:Name}
3414 \item [Name = \lt{}name\gt{}]
3416 \index[dir]{Directive!Name}
3417 The name of the Catalog. No necessary relation to the database server
3418 name. This name will be specified in the Client resource directive
3419 indicating that all catalog data for that Client is maintained in this
3420 Catalog. This directive is required.
3422 \label{Director:Catalog:Password}
3423 \item [password = \lt{}password\gt{}]
3424 \index[dir]{password}
3425 \index[dir]{Directive!password}
3426 This specifies the password to use when logging into the database. This
3427 directive is required.
3429 \label{Director:Catalog:DbName}
3430 \item [DB Name = \lt{}name\gt{}]
3431 \index[dir]{DB Name}
3432 \index[dir]{Directive!DB Name}
3433 This specifies the name of the database. If you use multiple catalogs
3434 (databases), you specify which one here. If you are using an external
3435 database server rather than the internal one, you must specify a name
3436 that is known to the server (i.e. you explicitly created the Bacula
3437 tables using this name. This directive is required.
3439 \label{Director:Catalog:User}
3440 \item [user = \lt{}user\gt{}]
3442 \index[dir]{Directive!user}
3443 This specifies what user name to use to log into the database. This
3444 directive is required.
3446 \label{Director:Catalog:DbSocket}
3447 \item [DB Socket = \lt{}socket-name\gt{}]
3448 \index[dir]{DB Socket}
3449 \index[dir]{Directive!DB Socket}
3450 This is the name of a socket to use on the local host to connect to the
3451 database. This directive is used only by MySQL and is ignored by SQLite.
3452 Normally, if neither {\bf DB Socket} or {\bf DB Address} are specified, MySQL
3453 will use the default socket. If the DB Socket is specified, the
3454 MySQL server must reside on the same machine as the Director.
3456 \label{Director:Catalog:DBAddress}
3457 \item [DB Address = \lt{}address\gt{}]
3458 \index[dir]{DB Address}
3459 \index[dir]{Directive!DB Address}
3460 This is the host address of the database server. Normally, you would specify
3461 this instead of {\bf DB Socket} if the database server is on another machine.
3462 In that case, you will also specify {\bf DB Port}. This directive is used
3463 only by MySQL and PostgreSQL and is ignored by SQLite if provided.
3464 This directive is optional.
3466 \label{Director:Catalog:DbPort}
3467 \item [DB Port = \lt{}port\gt{}]
3468 \index[dir]{DB Port}
3469 \index[dir]{Directive!DB Port}
3470 This defines the port to be used in conjunction with {\bf DB Address} to
3471 access the database if it is on another machine. This directive is used only
3472 by MySQL and PostgreSQL and is ignored by SQLite if provided. This
3473 directive is optional.
3475 \label{Director:Catalog:End}
3477 %% \item [Multiple Connections = \lt{}yes\vb{}no\gt{}]
3479 %% \index[dir]{Directive!Multiple Connections}
3480 %% By default, this directive is set to no. In that case, each job that uses
3482 %% same Catalog will use a single connection to the catalog. It will be shared,
3483 %% and Bacula will allow only one Job at a time to communicate. If you set this
3484 %% directive to yes, Bacula will permit multiple connections to the database,
3485 %% and the database must be multi-thread capable. For SQLite and PostgreSQL,
3486 %% this is no problem. For MySQL, you must be *very* careful to have the
3487 %% multi-thread version of the client library loaded on your system. When this
3488 %% directive is set yes, each Job will have a separate connection to the
3489 %% database, and the database will control the interaction between the
3491 %% Jobs. This can significantly speed up the database operations if you are
3492 %% running multiple simultaneous jobs. In addition, for SQLite and PostgreSQL,
3493 %% Bacula will automatically enable transactions. This can significantly speed
3494 %% up insertion of attributes in the database either for a single Job or
3495 %% multiple simultaneous Jobs.
3497 %% This directive has not been tested. Please test carefully before running it
3498 %% in production and report back your results.
3502 The following is an example of a valid Catalog resource definition:
3511 password = "" # no password = no security
3516 or for a Catalog on another machine:
3526 DB Address = remote.acme.com

3542 \section{The Console Resource}
3543 \index[general]{Console Resource}
3544 \index[general]{Resource!Console}
3546 As of Bacula version 1.33 and higher, there are three different kinds of
3547 consoles, which the administrator or user can use to interact with the
3548 Director. These three kinds of consoles comprise three different security
3552 \item The first console type is an {\bf anonymous} or {\bf default} console,
3553 which has full privileges. There is no console resource necessary for
3554 this type since the password is specified in the Director's resource and
3555 consequently such consoles do not have a name as defined on a {\bf Name
3556 =} directive. This is the kind of console that was initially
3557 implemented in versions prior to 1.33 and remains valid. Typically you
3558 would use it only for administrators.
3560 \item The second type of console, and new to version 1.33 and higher is a
3561 ``named'' console defined within a Console resource in both the Director's
3562 configuration file and in the Console's configuration file. Both the
3563 names and the passwords in these two entries must match much as is the
3564 case for Client programs.
3566 This second type of console begins with absolutely no privileges except
3567 those explicitly specified in the Director's Console resource. Thus you
3568 can have multiple Consoles with different names and passwords, sort of
3569 like multiple users, each with different privileges. As a default,
3570 these consoles can do absolutely nothing -- no commands whatsoever. You
3571 give them privileges or rather access to commands and resources by
3572 specifying access control lists in the Director's Console resource. The
3573 ACLs are specified by a directive followed by a list of access names.
3574 Examples of this are shown below.
3576 \item The third type of console is similar to the above mentioned one in that
3577 it requires a Console resource definition in both the Director and the
3578 Console. In addition, if the console name, provided on the {\bf Name =}
3579 directive, is the same as a Client name, that console is permitted to
3580 use the {\bf SetIP} command to change the Address directive in the
3581 Director's client resource to the IP address of the Console. This
3582 permits portables or other machines using DHCP (non-fixed IP addresses)
3583 to ``notify'' the Director of their current IP address.
3586 The Console resource is optional and need not be specified. The following
3587 directives are permitted within the Director's configuration resource:
3591 \label{Director:Console:Name}
3592 \item [Name = \lt{}name\gt{}]
3594 \index[dir]{Directive!Name}
3595 The name of the console. This name must match the name specified in the
3596 Console's configuration resource (much as is the case with Client
3599 \label{Director:Console:Password}
3600 \item [Password = \lt{}password\gt{}]
3601 \index[dir]{Password}
3602 \index[dir]{Directive!Password}
3603 Specifies the password that must be supplied for a named Bacula Console
3604 to be authorized. The same password must appear in the {\bf Console}
3605 resource of the Console configuration file. For added security, the
3606 password is never actually passed across the network but rather a
3607 challenge response hash code created with the password. This directive
3608 is required. If you have either {\bf /dev/random} {\bf bc} on your
3609 machine, Bacula will generate a random password during the configuration
3610 process, otherwise it will be left blank.
3612 The password is plain text. It is not generated through any special
3613 process. However, it is preferable for security reasons to choose
3616 \label{Director:Console:JobAcl}
3617 \item [JobACL = \lt{}name-list\gt{}]
3619 \index[dir]{Directive!JobACL}
3620 This directive is used to specify a list of Job resource names that can
3621 be accessed by the console. Without this directive, the console cannot
3622 access any of the Director's Job resources. Multiple Job resource names
3623 may be specified by separating them with commas, and/or by specifying
3624 multiple JobACL directives. For example, the directive may be specified
3629 JobACL = kernsave, "Backup client 1", "Backup client 2"
3630 JobACL = "RestoreFiles"
3635 With the above specification, the console can access the Director's resources
3636 for the four jobs named on the JobACL directives, but for no others.
3638 \label{Director:Console:ClientAcl}
3639 \item [ClientACL = \lt{}name-list\gt{}]
3640 \index[dir]{ClientACL}
3641 \index[dir]{Directive!ClientACL}
3642 This directive is used to specify a list of Client resource names that can
3644 accessed by the console.
3646 \label{Director:Console:StorageAcl}
3647 \item [StorageACL = \lt{}name-list\gt{}]
3648 \index[dir]{StorageACL}
3649 \index[dir]{Directive!StorageACL}
3650 This directive is used to specify a list of Storage resource names that can
3651 be accessed by the console.
3653 \label{Director:Console:ScheduleAcl}
3654 \item [ScheduleACL = \lt{}name-list\gt{}]
3655 \index[dir]{ScheduleACL}
3656 \index[dir]{Directive!ScheduleACL}
3657 This directive is used to specify a list of Schedule resource names that can
3658 be accessed by the console.
3660 \label{Director:Console:PoolAcl}
3661 \item [PoolACL = \lt{}name-list\gt{}]
3662 \index[dir]{PoolACL}
3663 \index[dir]{Directive!PoolACL}
3664 This directive is used to specify a list of Pool resource names that can be
3665 accessed by the console.
3667 \label{Director:Console:FileSetAcl}
3668 \item [FileSetACL = \lt{}name-list\gt{}]
3669 \index[dir]{FileSetACL}
3670 \index[dir]{Directive!FileSetACL}
3671 This directive is used to specify a list of FileSet resource names that
3672 can be accessed by the console.
3674 \label{Director:Console:CatalogAcl}
3675 \item [CatalogACL = \lt{}name-list\gt{}]
3676 \index[dir]{CatalogACL}
3677 \index[dir]{Directive!CatalogACL}
3678 This directive is used to specify a list of Catalog resource names that
3679 can be accessed by the console.
3681 \label{Director:Console:CommandAcl}
3682 \item [CommandACL = \lt{}name-list\gt{}]
3683 \index[dir]{CommandACL}
3684 \index[dir]{Directive!CommandACL}
3685 This directive is used to specify a list of of console commands that can
3686 be executed by the console.
3688 \label{Director:Console:WhereAcl}
3689 \item [WhereACL = \lt{}string\gt{}]
3690 \index[dir]{WhereACL}
3691 \index[dir]{Directive!WhereACL}
3692 This directive permits you to specify where a restricted console
3693 can restore files. If this directive is not specified, only the
3694 default restore location is permitted (normally {\bf
3695 /tmp/bacula-restores}. If {\bf *all*} is specified any path the
3696 user enters will be accepted (not very secure), any other
3697 value specified (there may be multiple WhereACL directives) will
3698 restrict the user to use that path. For example, on a Unix system,
3699 if you specify ``/'', the file will be restored to the original
3700 location. This directive is untested.
3704 Aside from Director resource names and console command names, the special
3705 keyword {\bf *all*} can be specified in any of the above access control lists.
3706 When this keyword is present, any resource or command name (which ever is
3707 appropriate) will be accepted. For an example configuration file, please see

3712 \label{CounterResource}
3713 \section{The Counter Resource}
3714 \index[general]{Resource!Counter}
3715 \index[general]{Counter Resource}
3717 The Counter Resource defines a counter variable that can be accessed by
3718 variable expansion used for creating Volume labels with the {\bf LabelFormat}
3720 \ilink{LabelFormat}{Label} directive in this chapter for more
3726 \index[dir]{Counter}
3727 \index[dir]{Directive!Counter}
3728 Start of the Counter resource. Counter directives are optional.
3730 \label{Director:Counter:Name}
3731 \item [Name = \lt{}name\gt{}]
3733 \index[dir]{Directive!Name}
3734 The name of the Counter. This is the name you will use in the variable
3735 expansion to reference the counter value.
3737 \label{Director:Counter:Minimum}
3738 \item [Minimum = \lt{}integer\gt{}]
3739 \index[dir]{Minimum}
3740 \index[dir]{Directive!Minimum}
3741 This specifies the minimum value that the counter can have. It also becomes
3742 the default. If not supplied, zero is assumed.
3744 \label{Director:Counter:Maximum}
3745 \item [Maximum = \lt{}integer\gt{}]
3746 \index[dir]{Maximum}
3747 \index[dir]{Directive!Maximum}
3748 \index[dir]{Directive!Maximum}
3749 This is the maximum value value that the counter can have. If not specified
3750 or set to zero, the counter can have a maximum value of 2,147,483,648 (2 to
3751 the 31 power). When the counter is incremented past this value, it is reset
3754 \label{Director:Counter:*WrapCounter}
3755 \item [*WrapCounter = \lt{}counter-name\gt{}]
3756 \index[dir]{*WrapCounter}
3757 \index[dir]{Directive!*WrapCounter}
3758 If this value is specified, when the counter is incremented past the
3760 and thus reset to the minimum, the counter specified on the {\bf WrapCounter}
3761 is incremented. (This is not currently implemented).
3763 \label{Director:Counter:Catalog}
3764 \item [Catalog = \lt{}catalog-name\gt{}]
3765 \index[dir]{Catalog}
3766 \index[dir]{Directive!Catalog}
3767 If this directive is specified, the counter and its values will be saved in
3768 the specified catalog. If this directive is not present, the counter will be
3769 redefined each time that Bacula is started.
