10 Of all the configuration files needed to run {\bf Bacula}, the Director's is
11 the most complicated, and the one that you will need to modify the most often
12 as you add clients or modify the FileSets.
14 For a general discussion of configuration files and resources including the
15 data types recognized by {\bf Bacula}. Please see the

21 \addcontentsline{toc}{subsection}{Director Resource Types}
23 Director resource type may be one of the following:
25 Job, JobDefs, Client, Storage, Catalog, Schedule, FileSet, Pool, Director, or
26 Messages. We present them here in the most logical order for defining them:
30 \ilink{Director}{DirectorResource4} -- to define the Director's
31 name and its access password used for authenticating the Console program.
32 Only a single Director resource definition may appear in the Director's
33 configuration file. If you have either {\bf /dev/random} or {\bf bc} on your
34 machine, Bacula will generate a random password during the configuration
35 process, otherwise it will be left blank.
37 \ilink{Job}{JobResource} -- to define the backup/restore Jobs
38 and to tie together the Client, FileSet and Schedule resources to be used
41 \ilink{JobDefs}{JobDefsResource} -- optional resource for
42 providing defaults for Job resources.
44 \ilink{Schedule}{ScheduleResource} -- to define when a Job is to
45 be automatically run by {\bf Bacula's} internal scheduler.
47 \ilink{FileSet}{FileSetResource} -- to define the set of files
48 to be backed up for each Client.
50 \ilink{Client}{ClientResource2} -- to define what Client is to be
53 \ilink{Storage}{StorageResource2} -- to define on what physical
54 device the Volumes should be mounted.
56 \ilink{Pool}{PoolResource} -- to define the pool of Volumes
57 that can be used for a particular Job.
59 \ilink{Catalog}{CatalogResource} -- to define in what database to
60 keep the list of files and the Volume names where they are backed up.
62 \ilink{Messages}{_ChapterStart15} -- to define where error and
63 information messages are to be sent or logged.
66 \subsection*{The Director Resource}
67 \label{DirectorResource4}
68 \index[general]{Director Resource}
69 \index[general]{Resource!Director}
70 \addcontentsline{toc}{subsection}{Director Resource}
72 The Director resource defines the attributes of the Directors running on the
73 network. In the current implementation, there is only a single Director
74 resource, but the final design will contain multiple Directors to maintain
75 index and media database redundancy.
81 Start of the Director resource. One and only one director resource must be
84 \item [Name = \lt{}name\gt{}]
86 The director name used by the system administrator. This directive is
89 \item [Description = \lt{}text\gt{}]
90 \index[dir]{Description }
91 The text field contains a description of the Director that will be displayed
92 in the graphical user interface. This directive is optional.
94 \item [Password = \lt{}UA-password\gt{}]
95 \index[dir]{Password }
96 Specifies the password that must be supplied for the default Bacula Console
97 to be authorized. The same password must appear in the {\bf Director}
98 resource of the Console configuration file. For added security, the password
99 is never actually passed across the network but rather a challenge response
100 hash code created with the password. This directive is required. If you have
101 either {\bf /dev/random} or {\bf bc} on your machine, Bacula will generate a
102 random password during the configuration process, otherwise it will be left
103 blank and you must manually supply it.
105 \item [Messages = \lt{}Messages-resource-name\gt{}]
106 \index[dir]{Messages }
107 The messages resource specifies where to deliver Director messages that are
108 not associated with a specific Job. Most messages are specific to a job and
109 will be directed to the Messages resource specified by the job. However,
110 there are a few messages that can occur when no job is running. This
111 directive is required.
113 \item [Working Directory = \lt{}Directory\gt{}]
114 \index[dir]{Working Directory }
115 This directive is mandatory and specifies a directory in which the Director
116 may put its status files. This directory should be used only by Bacula but
117 may be shared by other Bacula daemons. However, please note, if this
118 directory is shared with other Bacula daemons (the File daemon and Storage
119 daemon), you must ensure that the {\bf Name} given to each daemon is
120 unique so that the temporary filenames used do not collide. By default
121 the Bacula configure process creates unique daemon names by postfixing them
122 with -dir, -fd, and -sd. Standard shell expansion of the {\bf
123 Directory} is done when the configuration file is read so that values such
124 as {\bf \$HOME} will be properly expanded. This directive is required.
126 \item [Pid Directory = \lt{}Directory\gt{}]
127 \index[dir]{Pid Directory }
128 This directive is mandatory and specifies a directory in which the Director
129 may put its process Id file. The process Id file is used to shutdown
130 Bacula and to prevent multiple copies of Bacula from running simultaneously.
131 Standard shell expansion of the {\bf Directory} is done when the
132 configuration file is read so that values such as {\bf \$HOME} will be
135 Typically on Linux systems, you will set this to: {\bf /var/run}. If you are
136 not installing Bacula in the system directories, you can use the {\bf Working
137 Directory} as defined above. This directive is required.
139 \item [Scripts Directory = \lt{}Directory\gt{}]
140 \index[dir]{Scripts Directory }
141 This directive is optional and, if defined, specifies a directory in which
143 will look for the Python startup script {\bf DirStartup.py}. This directory
144 may be shared by other Bacula daemons. Standard shell expansion of the
145 directory is done when the configuration file is read so that values such
146 as {\bf \$HOME} will be properly expanded.
148 \item [QueryFile = \lt{}Path\gt{}]
149 \index[dir]{QueryFile }
150 This directive is mandatory and specifies a directory and file in which the
151 Director can find the canned SQL statements for the {\bf Query} command of
152 the Console. Standard shell expansion of the {\bf Path} is done when the
153 configuration file is read so that values such as {\bf \$HOME} will be
154 properly expanded. This directive is required.
155 \label{DirMaxConJobs}
157 \item [Maximum Concurrent Jobs = \lt{}number\gt{}]
158 \index[dir]{Maximum Concurrent Jobs }
159 \index[general]{Simultaneous Jobs}
160 \index[general]{Concurrent Jobs}
161 where \lt{}number\gt{} is the maximum number of total Director Jobs that
162 should run concurrently. The default is set to 1, but you may set it to a
165 Please note that the Volume format becomes much more complicated with
166 multiple simultaneous jobs, consequently, restores can take much longer if
167 Bacula must sort through interleaved volume blocks from multiple simultaneous
168 jobs. This can be avoided by having each simultaneously running job write to
169 a different volume or by using data spooling, which will first spool the data
170 to disk simultaneously, then write each spool file to the volume in
173 There may also still be some cases where directives such as {\bf Maximum
174 Volume Jobs} are not properly synchronized with multiple simultaneous jobs
175 (subtle timing issues can arise), so careful testing is recommended.
177 At the current time, there is no configuration parameter set to limit the
178 number of console connections. A maximum of five simultaneous console
179 connections are permitted.
181 For more details on getting concurrent jobs to run, please see
182 \ilink{Running Concurrent Jobs}{ConcurrentJobs} in the Tips chapter
185 \item [FD Connect Timeout = \lt{}time\gt{}]
186 \index[dir]{FD Connect Timeout }
187 where {\bf time} is the time that the Director should continue attempting
189 contact the File daemon to start a job, and after which the Director will
190 cancel the job. The default is 30 minutes.
192 \item [SD Connect Timeout = \lt{}time\gt{}]
193 \index[dir]{SD Connect Timeout }
194 where {\bf time} is the time that the Director should continue attempting
196 contact the Storage daemon to start a job, and after which the Director will
197 cancel the job. The default is 30 minutes.
199 \item [DirAddresses = \lt{}IP-address-specification\gt{}]
200 \index[dir]{DirAddresses }
201 Specify the ports and addresses on which the Director daemon will listen for
202 Bacula Console connections. Probably the simplest way to explain this is to
208 DirAddresses = { ip = {
209 addr = 1.2.3.4; port = 1205;}
211 addr = 1.2.3.4; port = http;}
224 addr = 201:220:222::2
227 addr = bluedot.thun.net
233 where ip, ip4, ip6, addr, and port are all keywords. Note, that the address
234 can be specified as either a dotted quadruple, or IPv6 colon notation, or as
235 a symbolic name (only in the ip specification). Also, port can be specified
236 as a number or as the mnemonic value from the /etc/services file. If a port
237 is not specified, the default will be used. If an ip section is specified,
238 the resolution can be made either by IPv4 or IPv6. If ip4 is specified, then
239 only IPv4 resolutions will be permitted, and likewise with ip6.
241 \item [DIRport = \lt{}port-number\gt{}]
242 \index[dir]{DIRport }
243 Specify the port (a positive integer) on which the Director daemon will
244 listen for Bacula Console connections. This same port number must be
245 specified in the Director resource of the Console configuration file. The
246 default is 9101, so normally this directive need not be specified. This
247 directive is not needed if you specify DirAddresses.
249 \item [DirAddress = \lt{}IP-Address\gt{}]
250 \index[dir]{DirAddress }
251 This directive is optional, but if it is specified, it will cause the
252 Director server (for the Console program) to bind to the specified {\bf
253 IP-Address}, which is either a domain name or an IP address specified as a
254 dotted quadruple in string or quoted string format. If this directive is not
255 specified, the Director will bind to any available address (the default).
256 Note, unlike the DirAddresses specification noted above, this directive only
257 permits a single address to be specified. This directive is not needed if you
258 specify a DirAddresses (not plural).
261 The following is an example of a valid Director resource definition:
267 WorkingDirectory = "$HOME/bacula/bin/working"
268 Password = UA_password
269 PidDirectory = "$HOME/bacula/bin/working"
270 QueryFile = "$HOME/bacula/bin/query.sql"
276 \subsection*{The Job Resource}
278 \index[general]{Resource!Job}
279 \index[general]{Job Resource}
280 \addcontentsline{toc}{subsection}{Job Resource}
282 The Job resource defines a Job (Backup, Restore, ...) that Bacula must
283 perform. Each Job resource definition contains the name of a Client and
284 a FileSet to backup, the Schedule for the Job, where the data
285 are to be stored, and what media Pool can be used. In effect, each Job
286 resource must specify What, Where, How, and When or FileSet, Storage,
287 Backup/Restore/Level, and Schedule respectively. Note, the FileSet must
288 be specified for a restore job for historical reasons, but it is no longer used.
290 Only a single type ({\bf Backup}, {\bf Restore}, ...) can be specified for any
291 job. If you want to backup multiple FileSets on the same Client or multiple
292 Clients, you must define a Job for each one.
298 Start of the Job resource. At least one Job resource is required.
300 \item [Name = \lt{}name\gt{}]
302 The Job name. This name can be specified on the {\bf Run} command in the
303 console program to start a job. If the name contains spaces, it must be
304 specified between quotes. It is generally a good idea to give your job the
305 same name as the Client that it will backup. This permits easy
306 identification of jobs.
308 When the job actually runs, the unique Job Name will consist of the name you
309 specify here followed by the date and time the job was scheduled for
310 execution. This directive is required.
312 \item [Type = \lt{}job-type\gt{}]
314 The {\bf Type} directive specifies the Job type, which may be one of the
315 following: {\bf Backup}, {\bf Restore}, {\bf Verify}, or {\bf Admin}. This
316 directive is required. Within a particular Job Type, there are also Levels
317 as discussed in the next item.
323 Run a backup Job. Normally you will have at least one Backup job for each
324 client you want to save. Normally, unless you turn off cataloging, most all
325 the important statistics and data concerning files backed up will be placed
330 Run a restore Job. Normally, you will specify only one Restore job which
332 as a sort of prototype that you will modify using the console program in
333 order to perform restores. Although certain basic information from a Restore
334 job is saved in the catalog, it is very minimal compared to the information
335 stored for a Backup job -- for example, no File database entries are
336 generated since no Files are saved.
340 Run a verify Job. In general, {\bf verify} jobs permit you to compare the
341 contents of the catalog to the file system, or to what was backed up. In
342 addition, to verifying that a tape that was written can be read, you can
343 also use {\bf verify} as a sort of tripwire intrusion detection.
347 Run an admin Job. An {\bf Admin} job can be used to periodically run catalog
348 pruning, if you do not want to do it at the end of each {\bf Backup} Job.
349 Although an Admin job is recorded in the catalog, very little data is saved.
354 \item [Level = \lt{}job-level\gt{}]
356 The Level directive specifies the default Job level to be run. Each
358 Job Type (Backup, Restore, ...) has a different set of Levels that can be
359 specified. The Level is normally overridden by a different value that is
360 specified in the {\bf Schedule} resource. This directive is not required, but
361 must be specified either by a {\bf Level} directive or as an override
362 specified in the {\bf Schedule} resource.
364 For a {\bf Backup} Job, the Level may be one of the following:
370 is all files in the FileSet whether or not they have changed.
373 \index[dir]{Incremental}
374 is all files specified in the FileSet that have changed since the last successful backup of the
375 the same Job using the same FileSet and Client.
376 If the Director cannot find a previous valid Full backup then
377 the job will be upgraded into a Full backup. When the Director looks for a
378 valid backup record in the catalog database, it looks for a previous
382 \item The same Job name.
383 \item The same Client name.
384 \item The same FileSet (any change to the definition of the FileSet such as
385 adding or deleting a file in the Include or Exclude sections constitutes a
387 \item The Job was a Full, Differential, or Incremental backup.
388 \item The Job terminated normally (i.e. did not fail or was not canceled).
391 If all the above conditions do not hold, the Director will upgrade the
392 Incremental to a Full save. Otherwise, the Incremental backup will be
393 performed as requested.
395 The File daemon (Client) decides which files to backup for an Incremental
396 backup by comparing start time of the prior Job (Full, Differential, or
397 Incremental) against the time each file was last "modified" (st\_mtime) and
398 the time its attributes were last "changed"(st\_ctime). If the file was
399 modified or its attributes changed on or after this start time, it will then
402 Please note that some virus scanning software may change st\_ctime while
403 doing the scan. For example, if the virus scanning program attempts to
404 reset the access time (st\_atime), which Bacula does not use, it will cause
405 st\_ctime to change and hence Bacula will backup the file during an
406 Incremental or Differential backup. In the case of Sophos virus scanning, you
407 can prevent it from resetting the access time (st\_atime) and hence changing
408 st\_ctime by using the {\bf \verb:--:no-reset-atime} option. For other
410 please see their manual.
412 When Bacula does an Incremental backup, all modified files that are still on
413 the system are backed up. However, any file that has been deleted since the
414 last Full backup remains in the Bacula catalog, which means that if between
415 a Full save and the time you do a restore, some files are deleted, those
416 deleted files will also be restored. The deleted files will no longer appear
417 in the catalog after doing another Full save. However, to remove deleted
418 files from the catalog during an Incremental backup is quite a time consuming
419 process and not currently implemented in Bacula.
421 In addition, if you move a directory rather than copy it, the files in it do not
422 have their modification time (st\_mtime) or their attribute change time
424 changed. As a consequence, those files will probably not be backed up by an
426 or Differential backup which depend solely on these time stamps. If you move a
428 and wish it to be properly backed up, it is generally preferable to copy it,
433 \index[dir]{Differential}
434 is all files specified in the FileSet that have changed since the last
435 successful Full backup of the same Job. If the Director cannot find a
436 valid previous Full backup for the same Job, FileSet, and Client,
437 backup, then the Differential job will be upgraded into a Full backup.
438 When the Director looks for a valid Full backup record in the catalog
439 database, it looks for a previous Job with:
442 \item The same Job name.
443 \item The same Client name.
444 \item The same FileSet (any change to the definition of the FileSet such as
445 adding or deleting a file in the Include or Exclude sections constitutes a
447 \item The Job was a FULL backup.
448 \item The Job terminated normally (i.e. did not fail or was not canceled).
451 If all the above conditions do not hold, the Director will upgrade the
452 Differential to a Full save. Otherwise, the Differential backup will be
453 performed as requested.
455 The File daemon (Client) decides which files to backup for a differential
456 backup by comparing the start time of the prior Full backup Job against the
457 time each file was last "modified" (st\_mtime) and the time its attributes
458 were last "changed" (st\_ctime). If the file was modified or its attributes
459 were changed on or after this start time, it will then be backed up. The
460 start time used is displayed after the {\bf Since} on the Job report. In rare
461 cases, using the start time of the prior backup may cause some files to be
462 backed up twice, but it ensures that no change is missed. As with the
463 Incremental option, you should ensure that the clocks on your server and
464 client are synchronized or as close as possible to avoid the possibility of a
465 file being skipped. Note, on versions 1.33 or greater Bacula automatically
466 makes the necessary adjustments to the time between the server and the client
467 so that the times Bacula uses are synchronized.
469 When Bacula does a Differential backup, all modified files that are still
470 on the system are backed up. However, any file that has been deleted since
471 the last Full backup remains in the Bacula catalog, which means that if
472 between a Full save and the time you do a restore, some files are deleted,
473 those deleted files will also be restored. The deleted files will no
474 longer appear in the catalog after doing another Full save. However, to
475 remove deleted files from the catalog during a Differential backup is quite
476 a time consuming process and not currently implemented in Bacula. It is,
477 however, a planned future feature.
480 As noted above, if you move a directory rather than copy it, the
481 files in it do not have their modification time (st\_mtime) or
482 their attribute change time (st\_ctime) changed. As a
483 consequence, those files will probably not be backed up by an
484 Incremental or Differential backup which depend solely on these
485 time stamps. If you move a directory, and wish it to be
486 properly backed up, it is generally preferable to copy it, then
487 delete the original. Alternatively, you can move the directory, then
488 use the {\bf touch} program to update the timestamps.
490 Every once and a while, someone asks why we need Differential
491 backups as long as Incremental backups pickup all changed files.
492 There are possibly many answers to this question, but the one
493 that is the most important for me is that it effectively combines
494 all the Incremental and Differential backups since the last Full
495 backup into a single Differential backup. This has two effects:
496 1. It gives some redundancy. 2. More importantly, it reduces the
497 number of Volumes that are needed to do a restore effectively
498 eliminating the need to read all the volumes on which the
499 preceding Incremental and Differential backups since the last
505 For a {\bf Restore} Job, no level needs to be specified.
507 For a {\bf Verify} Job, the Level may be one of the following:
512 \index[dir]{InitCatalog}
513 does a scan of the specified {\bf FileSet} and stores the file
514 attributes in the Catalog database. Since no file data is saved, you
515 might ask why you would want to do this. It turns out to be a very
516 simple and easy way to have a {\bf Tripwire} like feature using {\bf
517 Bacula}. In other words, it allows you to save the state of a set of
518 files defined by the {\bf FileSet} and later check to see if those files
519 have been modified or deleted and if any new files have been added.
520 This can be used to detect system intrusion. Typically you would
521 specify a {\bf FileSet} that contains the set of system files that
522 should not change (e.g. /sbin, /boot, /lib, /bin, ...). Normally, you
523 run the {\bf InitCatalog} level verify one time when your system is
524 first setup, and then once again after each modification (upgrade) to
525 your system. Thereafter, when your want to check the state of your
526 system files, you use a {\bf Verify} {\bf level = Catalog}. This
527 compares the results of your {\bf InitCatalog} with the current state of
532 Compares the current state of the files against the state previously
533 saved during an {\bf InitCatalog}. Any discrepancies are reported. The
534 items reported are determined by the {\bf verify} options specified on
535 the {\bf Include} directive in the specified {\bf FileSet} (see the {\bf
536 FileSet} resource below for more details). Typically this command will
537 be run once a day (or night) to check for any changes to your system
540 Please note! If you run two Verify Catalog jobs on the same client at
541 the same time, the results will certainly be incorrect. This is because
542 Verify Catalog modifies the Catalog database while running in order to
545 \item [VolumeToCatalog]
546 \index[dir]{VolumeToCatalog}
547 This level causes Bacula to read the file attribute data written to the
548 Volume from the last Job. The file attribute data are compared to the values
549 saved in the Catalog database and any differences are reported. This is
550 similar to the {\bf Catalog} level except that instead of comparing the disk
551 file attributes to the catalog database, the attribute data written to the
552 Volume is read and compared to the catalog database. Although the attribute
553 data including the signatures (MD5 or SHA1) are compared, the actual file data
554 is not compared (it is not in the catalog).
556 Please note! If you run two Verify VolumeToCatalog jobs on the same client at
557 the same time, the results will certainly be incorrect. This is because the
558 Verify VolumeToCatalog modifies the Catalog database while running.
560 \item [DiskToCatalog]
561 \index[dir]{DiskToCatalog}
562 This level causes Bacula to read the files as they currently are on disk,
564 to compare the current file attributes with the attributes saved in the
565 catalog from the last backup for the job specified on the {\bf VerifyJob}
566 directive. This level differs from the {\bf Catalog} level described above by
567 the fact that it doesn't compare against a previous Verify job but against a
568 previous backup. When you run this level, you must supply the verify options
569 on your Include statements. Those options determine what attribute fields are
572 This command can be very useful if you have disk problems because it will
573 compare the current state of your disk against the last successful backup,
574 which may be several jobs.
576 Note, the current implementation (1.32c) does not identify files that have
580 \item [Verify Job = \lt{}Job-Resource-Name\gt{}]
581 \index[dir]{Verify Job }
582 If you run a verify job without this directive, the last job run will be
583 compared with the catalog, which means that you must immediately follow a
584 backup by a verify command. If you specify a {\bf Verify Job} Bacula will
585 find the last job with that name that ran. This permits you to run all your
586 backups, then run Verify jobs on those that you wish to be verified (most
587 often a {\bf VolumeToCatalog}) so that the tape just written is re-read.
589 \item [JobDefs = \lt{}JobDefs-Resource-Name\gt{}]
590 \index[dir]{JobDefs }
591 If a JobDefs-Resource-Name is specified, all the values contained in the
592 named JobDefs resource will be used as the defaults for the current Job. Any
593 value that you explicitly define in the current Job resource, will override
594 any defaults specified in the JobDefs resource. The use of this directive
595 permits writing much more compact Job resources where the bulk of the
596 directives are defined in one or more JobDefs. This is particularly useful if
597 you have many similar Jobs but with minor variations such as different
598 Clients. A simple example of the use of JobDefs is provided in the default
599 bacula-dir.conf file.
601 \item [Bootstrap = \lt{}bootstrap-file\gt{}]
602 \index[dir]{Bootstrap }
603 The Bootstrap directive specifies a bootstrap file that, if provided, will
604 be used during {\bf Restore} Jobs and is ignored in other Job types. The {\bf
605 bootstrap} file contains the list of tapes to be used in a restore Job as
606 well as which files are to be restored. Specification of this directive is
607 optional, and if specified, it is used only for a restore job. In addition,
608 when running a Restore job from the console, this value can be changed.
610 If you use the {\bf Restore} command in the Console program, to start a
611 restore job, the {\bf bootstrap} file will be created automatically from the
612 files you select to be restored.
614 For additional details of the {\bf bootstrap} file, please see
615 \ilink{Restoring Files with the Bootstrap File}{_ChapterStart43}
616 chapter of this manual.
618 \label{writebootstrap}
619 \item [Write Bootstrap = \lt{}bootstrap-file-specification\gt{}]
621 The {\bf writebootstrap} directive specifies a file name where Bacula will
622 write a {\bf bootstrap} file for each Backup job run. Thus this directive
623 applies only to Backup Jobs. If the Backup job is a Full save, Bacula will
624 erase any current contents of the specified file before writing the bootstrap
625 records. If the Job is an Incremental save, Bacula will append the current
626 bootstrap record to the end of the file.
628 Using this feature, permits you to constantly have a bootstrap file that can
629 recover the current state of your system. Normally, the file specified should
630 be a mounted drive on another machine, so that if your hard disk is lost,
631 you will immediately have a bootstrap record available. Alternatively, you
632 should copy the bootstrap file to another machine after it is updated.
634 If the {\bf bootstrap-file-specification} begins with a vertical bar (|),
635 Bacula will use the specification as the name of a program to which it will
636 pipe the bootstrap record. It could for example be a shell script that emails
637 you the bootstrap record.
639 For more details on using this file, please see the chapter entitled
640 \ilink{The Bootstrap File}{_ChapterStart43} of this manual.
642 \item [Client = \lt{}client-resource-name\gt{}]
644 The Client directive specifies the Client (File daemon) that will be used in
645 the current Job. Only a single Client may be specified in any one Job. The
646 Client runs on the machine to be backed up, and sends the requested files to
647 the Storage daemon for backup, or receives them when restoring. For
648 additional details, see the
649 \ilink{Client Resource section}{ClientResource2} of this chapter.
650 This directive is required.
652 \item [FileSet = \lt{}FileSet-resource-name\gt{}]
653 \index[dir]{FileSet }
654 The FileSet directive specifies the FileSet that will be used in the
656 Job. The FileSet specifies which directories (or files) are to be backed up,
657 and what options to use (e.g. compression, ...). Only a single FileSet
658 resource may be specified in any one Job. For additional details, see the
659 \ilink{FileSet Resource section}{FileSetResource} of this
660 chapter. This directive is required.
662 \item [Messages = \lt{}messages-resource-name\gt{}]
663 \index[dir]{Messages }
664 The Messages directive defines what Messages resource should be used for
666 job, and thus how and where the various messages are to be delivered. For
667 example, you can direct some messages to a log file, and others can be sent
668 by email. For additional details, see the
669 \ilink{Messages Resource}{_ChapterStart15} Chapter of this
670 manual. This directive is required.
672 \item [Pool = \lt{}pool-resource-name\gt{}]
674 The Pool directive defines the pool of Volumes where your data can be backed
675 up. Many Bacula installations will use only the {\bf Default} pool. However,
676 if you want to specify a different set of Volumes for different Clients or
677 different Jobs, you will probably want to use Pools. For additional details,
679 \ilink{Pool Resource section}{PoolResource} of this chapter. This
680 directive is required.
682 \item [Full Backup Pool = \lt{}pool-resource-name\gt{}]
683 \index[dir]{Full Backup Pool }
684 The {\it Full Backup Pool} specifies a Pool to be used for Full backups. It
685 will override any Pool specification during a Full backup. This directive is
688 \item [Differential Backup Pool = \lt{}pool-resource-name\gt{}]
689 \index[dir]{Differential Backup Pool }
690 The {\it Differential Backup Pool} specifies a Pool to be used for
691 Differential backups. It will override any Pool specification during a
692 Differential backup. This directive is optional.
694 \item [Incremental Backup Pool = \lt{}pool-resource-name\gt{}]
695 \index[dir]{Incremental Backup Pool }
696 The {\it Incremental Backup Pool} specifies a Pool to be used for
698 backups. It will override any Pool specification during an Incremental
700 This directive is optional.
702 \item [Schedule = \lt{}schedule-name\gt{}]
703 \index[dir]{Schedule }
704 The Schedule directive defines what schedule is to be used for the Job.
705 The schedule in turn determines when the Job will be automatically
706 started and what Job level (i.e. Full, Incremental, ...) is to be run.
707 This directive is optional, and if left out, the Job can only be started
708 manually using the Console program. Although you may specify only a
709 single Schedule resource for any one job, the Schedule resource may
710 contain multiple {\bf Run} directives, which allow you to run the Job at
711 many different times, and each {\bf run} directive permits overriding
712 the default Job Level Pool, Storage, and Messages resources. This gives
713 considerable flexibility in what can be done with a single Job. For
714 additional details, see the \ilink{Schedule Resource
715 Chapter}{ScheduleResource} of this manual.
718 \item [Storage = \lt{}storage-resource-name\gt{}]
719 \index[dir]{Storage }
720 The Storage directive defines the name of the storage services where you
722 to backup the FileSet data. For additional details, see the
723 \ilink{Storage Resource Chapter}{StorageResource2} of this manual.
724 This directive is required.
726 \item [Max Start Delay = \lt{}time\gt{}]
727 \index[dir]{Max Start Delay }
728 The time specifies the maximum delay between the scheduled time and the
729 actual start time for the Job. For example, a job can be scheduled to
730 run at 1:00am, but because other jobs are running, it may wait to run.
731 If the delay is set to 3600 (one hour) and the job has not begun to run
732 by 2:00am, the job will be canceled. This can be useful, for example,
733 to prevent jobs from running during day time hours. The default is 0
734 which indicates no limit.
736 \item [Max Run Time = \lt{}time\gt{}]
737 \index[dir]{Max Run Time }
738 The time specifies the maximum allowed time that a job may run, counted
739 from when the job starts, ({\bf not} necessarily the same as when the
740 job was scheduled). This directive is implemented in version 1.33 and
743 \item [Max Wait Time = \lt{}time\gt{}]
744 \index[dir]{Max Wait Time }
745 The time specifies the maximum allowed time that a job may block waiting
746 for a resource (such as waiting for a tape to be mounted, or waiting for
747 the storage or file daemons to perform their duties), counted from the
748 when the job starts, ({\bf not} necessarily the same as when the job was
749 scheduled). This directive is implemented only in version 1.33 and
754 \item [Incremental Max Wait Time = \lt{}time\gt{}]
755 \index[dir]{Incremental Max Wait Time }
756 The time specifies the maximum allowed time that an Incremental backup
757 job may block waiting for a resource (such as waiting for a tape to be
758 mounted, or waiting for the storage or file daemons to perform their
759 duties), counted from the when the job starts, ({\bf not} necessarily
760 the same as when the job was scheduled). Please note that if there is a
761 {\bf Max Wait Time} it may also be applied to the job.
763 \item [Differential Max Wait Time = \lt{}time\gt{}]
764 \index[dir]{Differential Max Wait Time }
765 The time specifies the maximum allowed time that a Differential backup
766 job may block waiting for a resource (such as waiting for a tape to be
767 mounted, or waiting for the storage or file daemons to perform their
768 duties), counted from the when the job starts, ({\bf not} necessarily
769 the same as when the job was scheduled). Please note that if there is a
770 {\bf Max Wait Time} it may also be applied to the job.
772 \item [Prefer Mounted Volumes = \lt{}yes|no\gt{}]
773 \index[dir]{Prefer Mounted Volumes}
774 It the Prefer Mounted Volumes directive is set to {\bf yes}
775 (default yes), it is used to inform the Storage daemon
776 to select either an Autochanger or a drive with a valid
777 Volume already mounted in preference to a drive that is
778 not ready. If none is available, it will select the first
779 available drive. If the directive is set to {\bf no}, the
780 Storage daemon will prefer finding an unused drive. This
781 can potentially be useful for those sites that prefer to
782 maximum backup throughput at the expense of using additional
786 \item [Prune Jobs = \lt{}yes|no\gt{}]
787 \index[dir]{Prune Jobs }
788 Normally, pruning of Jobs from the Catalog is specified on a Client by
789 Client basis in the Client resource with the {\bf AutoPrune} directive.
790 If this directive is specified (not normally) and the value is {\bf
791 yes}, it will override the value specified in the Client resource. The
795 \item [Prune Files = \lt{}yes|no\gt{}]
796 \index[dir]{Prune Files }
797 Normally, pruning of Files from the Catalog is specified on a Client by
798 Client basis in the Client resource with the {\bf AutoPrune} directive.
799 If this directive is specified (not normally) and the value is {\bf
800 yes}, it will override the value specified in the Client resource. The
803 \item [Prune Volumes = \lt{}yes|no\gt{}]
804 \index[dir]{Prune Volumes }
805 Normally, pruning of Volumes from the Catalog is specified on a Client
806 by Client basis in the Client resource with the {\bf AutoPrune}
807 directive. If this directive is specified (not normally) and the value
808 is {\bf yes}, it will override the value specified in the Client
809 resource. The default is {\bf no}.
811 \item [Run Before Job = \lt{}command\gt{}]
812 \index[dir]{Run Before Job }
813 The specified {\bf command} is run as an external program prior to
814 running the current Job. Any output sent by the command to standard output
815 will be included in the Bacula job report. The command string must be a
816 valid program name or name of a shell script. This directive is not
817 required, but if it is defined, and if the exit code of the program run
818 is non-zero, the current Bacula job will be canceled. In addition, the
819 command string is parsed then fed to the execvp() function, which means
820 that the path will be searched to execute your specified command, but
821 there is no shell interpretation, as a consequence, if you invoke
822 complicated commands or want any shell features such as redirection or
823 piping, you must call a shell script and do it inside that script.
825 Before submitting the specified command to the operating system, Bacula
826 performs character substitution of the following characters:
844 The Job Exit Status code \%e edits the following values:
846 \index[dir]{Exit Status}
853 \item Unknown term code
856 Thus if you edit it on a command line, you will need to enclose
857 it within some sort of quotes.
859 Bacula checks the exit status of the RunBeforeJob program. If it is
860 non-zero, the job will be error terminated. Lutz Kittler has pointed
861 out that using the RunBeforJob directive can be a simple way to modify
862 your schedules during a holiday. For example, suppose that you normally
863 do Full backups on Fridays, but Thursday and Friday are holidays. To
864 avoid having to change tapes between Thursday and Friday when no one is
865 in the office, you can create a RunBeforeJob that returns a non-zero
866 status on Thursday and zero on all other days. That way, the Thursday
867 job will not run, and on Friday the tape you inserted on Wednesday
868 before leaving will be used.
870 \item [Run After Job = \lt{}command\gt{}]
871 \index[dir]{Run After Job }
872 The specified {\bf command} is run as an external program after the
873 current job terminates. This directive is not required. The command
874 string must be a valid program name or name of a shell script. If the
875 exit code of the program run is non-zero, the current Bacula job will
876 terminate in error. Before submitting the specified command to the
877 operating system, Bacula performs character substitution as described
878 above for the {\bf Run Before Job} directive.
880 An example of the use of this directive is given in the
881 \ilink{Tips Chapter}{JobNotification} of this manual. As of version
882 1.30, Bacula checks the exit status of the RunAfter program. If it is
883 non-zero, the job will be terminated in error.
885 \item [Client Run Before Job = \lt{}command\gt{}]
886 \index[dir]{Client Run Before Job }
887 This directive is the same as {\bf Run Before Job} except that the program is run on
888 the client machine. The same restrictions apply to Unix systems as noted
889 above for the {\bf Run Before Job}. In addition, for a Windows client on
890 version 1.33 and above, please take careful note that you must ensure a
891 correct path to your script. The script or program can be a .com, .exe or
892 a .bat file. However, if you specify a path, you must also specify the full
893 extension. Unix like commands will not work unless you have installed and
894 properly configured Cygwin in addition to and separately from Bacula.
896 {\bf Special Windows Considerations}
897 The command can be anything that cmd.exe or command.com will recognize as an
898 executable file. Specifying the executable's extension is optional, unless
899 there is an ambiguity. (i.e. ls.bat, ls.exe)
901 The System \%Path\% will be searched for the command. (under the environment
902 variable dialog you have have both System Environment and User Environment,
903 we believe that only the System environment will be available to bacula-fd,
904 if it is running as a service.)
906 System environment variables can be referenced with \%var\% and
907 used as either part of the command name or arguments.
909 When specifying a full path to an executable if the path or executable name
910 contains whitespace or special characters they will need to be quoted.
911 Arguments containing whitespace or special characters will also have to be
916 ClientRunBeforeJob = "\"C:/Program Files/Software
917 Vendor/Executable\" /arg1 /arg2 \"foo bar\""
921 The special characters \&()[]\{\}\^{}=;!'+,`\~{} will need to be quoted if
922 they are part of a filename or argument.
924 If someone is logged in, a blank "command" window running the commands
926 be present during the execution of the command.
928 Some Suggestions from Phil Stracchino for running on Win32 machines with the
929 native Win32 File daemon:
932 \item You might want the ClientRunBeforeJob directive to specify a .bat file
933 which runs the actual client-side commands, rather than trying to run
935 example) regedit /e directly.
936 \item The batch file should explicitly 'exit 0' on successful completion.
937 \item The path to the batch file should be specified in Unix form:
939 ClientRunBeforeJob = "c:/bacula/bin/systemstate.bat"
941 rather than DOS/Windows form:
945 "c:\textbackslash{}bacula\textbackslash{}bin\textbackslash{}systemstate.bat"
949 The following example of the use of the Client Run Before Job directive was
950 submitted by a user:\\
951 You could write a shell script to back up a DB2 database to a FIFO. The shell
961 db2 BACKUP DATABASE mercuryd TO $DIR/dbpipe WITHOUT PROMPTING &
966 The following line in the Job resource in the bacula-dir.conf file:
969 Client Run Before Job = "su - mercuryd -c \"/u01/mercuryd/backupdb.sh '%t'
973 When the job is run, you will get messages from the output of the script
975 that the backup has started. Even though the command being run is
976 backgrounded with \&, the job will block until the "db2 BACKUP DATABASE"
978 thus the backup stalls.
980 To remedy this situation, the "db2 BACKUP DATABASE" line should be changed to
985 db2 BACKUP DATABASE mercuryd TO $DIR/dbpipe WITHOUT PROMPTING > $DIR/backup.log
990 It is important to redirect the input and outputs of a backgrounded command to
991 /dev/null to prevent the script from blocking.
994 \item [Client Run After Job = \lt{}command\gt{}]
995 \index[dir]{Client Run After Job }
996 This directive is the same as {\bf Run After Job} except that it is run on
998 client machine. Note, please see the notes above in {\bf Client Run Before
999 Job} concerning Windows clients.
1001 \item [Rerun Failed Levels = \lt{}yes|no\gt{}]
1002 \index[dir]{Rerun Failed Levels }
1003 If this directive is set to {\bf yes} (default no), and Bacula detects that
1005 previous job at a higher level (i.e. Full or Differential) has failed, the
1006 current job level will be upgraded to the higher level. This is particularly
1007 useful for Laptops where they may often be unreachable, and if a prior Full
1008 save has failed, you wish the very next backup to be a Full save rather
1010 whatever level it is started as.
1012 \item [Spool Data = \lt{}yes|no\gt{}]
1013 \index[dir]{Spool Data }
1014 If this directive is set to {\bf yes} (default no), the Storage daemon will
1015 be requested to spool the data for this Job to disk rather than write it
1016 directly to tape. Once all the data arrives or the spool files' maximum sizes
1017 are reached, the data will be despooled and written to tape. When this
1018 directive is set to yes, the Spool Attributes is also automatically set to
1019 yes. Spooling data prevents tape shoe-shine (start and stop) during
1020 Incremental saves. This option should not be used if you are writing to a
1023 \item [Spool Attributes = \lt{}yes|no\gt{}]
1024 \index[dir]{Spool Attributes }
1025 The default is set to {\bf no}, which means that the File attributes are
1027 by the Storage daemon to the Director as they are stored on tape. However,
1028 if you want to avoid the possibility that database updates will slow down
1029 writing to the tape, you may want to set the value to {\bf yes}, in which
1030 case the Storage daemon will buffer the File attributes and Storage
1031 coordinates to a temporary file in the Working Directory, then when writing
1032 the Job data to the tape is completed, the attributes and storage coordinates
1033 will be sent to the Director.
1035 \item [Where = \lt{}directory\gt{}]
1037 This directive applies only to a Restore job and specifies a prefix to the
1038 directory name of all files being restored. This permits files to be restored
1039 in a different location from which they were saved. If {\bf Where} is not
1040 specified or is set to backslash ({\bf /}), the files will be restored to
1041 their original location. By default, we have set {\bf Where} in the example
1042 configuration files to be {\bf /tmp/bacula-restores}. This is to prevent
1043 accidental overwriting of your files.
1045 \item [Replace = \lt{}replace-option\gt{}]
1046 \index[dir]{Replace }
1047 This directive applies only to a Restore job and specifies what happens when
1048 Bacula wants to restore a file or directory that already exists. You have the
1049 following options for {\bf replace-option}:
1055 when the file to be restored already exists, it is deleted and then replaced
1057 the copy that was backed up.
1060 \index[dir]{ifnewer}
1061 if the backed up file (on tape) is newer than the existing file, the existing
1062 file is deleted and replaced by the back up.
1065 \index[dir]{ifolder}
1066 if the backed up file (on tape) is older than the existing file, the existing
1067 file is deleted and replaced by the back up.
1071 if the backed up file already exists, Bacula skips restoring this file.
1074 \item [Prefix Links=\lt{}yes|no\gt{}]
1075 \index[dir]{Prefix Links}
1076 If a {\bf Where} path prefix is specified for a recovery job, apply it
1077 to absolute links as well. The default is {\bf No}. When set to {\bf
1078 Yes} then while restoring files to an alternate directory, any absolute
1079 soft links will also be modified to point to the new alternate
1080 directory. Normally this is what is desired -- i.e. everything is self
1081 consistent. However, if you wish to later move the files to their
1082 original locations, all files linked with absolute names will be broken.
1084 \item [Maximum Concurrent Jobs = \lt{}number\gt{}]
1085 \index[dir]{Maximum Concurrent Jobs }
1086 where \lt{}number\gt{} is the maximum number of Jobs from the current
1087 Job resource that can run concurrently. Note, this directive limits
1088 only Jobs with the same name as the resource in which it appears. Any
1089 other restrictions on the maximum concurrent jobs such as in the
1090 Director, Client, or Storage resources will also apply in addition to
1091 the limit specified here. The default is set to 1, but you may set it
1092 to a larger number. We strongly recommend that you read the WARNING
1093 documented under \ilink{ Maximum Concurrent Jobs}{DirMaxConJobs} in the
1094 Director's resource.
1096 \item [Reschedule On Error = \lt{}yes|no\gt{}]
1097 \index[dir]{Reschedule On Error }
1098 If this directive is enabled, and the job terminates in error, the job
1099 will be rescheduled as determined by the {\bf Reschedule Interval} and
1100 {\bf Reschedule Times} directives. If you cancel the job, it will not
1101 be rescheduled. The default is {\bf no} (i.e. the job will not be
1105 This specification can be useful for portables, laptops, or other
1106 machines that are not always connected to the network or switched on.
1108 \item [Reschedule Interval = \lt{}time-specification\gt{}]
1109 \index[dir]{Reschedule Interval }
1110 If you have specified {\bf Reschedule On Error = yes} and the job
1111 terminates in error, it will be rescheduled after the interval of time
1112 specified by {\bf time-specification}. See \ilink{the time
1113 specification formats}{Time} in the Configure chapter for details of
1114 time specifications. If no interval is specified, the job will not be
1115 rescheduled on error.
1117 \item [Reschedule Times = \lt{}count\gt{}]
1118 \index[dir]{Reschedule Times }
1119 This directive specifies the maximum number of times to reschedule the
1120 job. If it is set to zero (the default) the job will be rescheduled an
1121 indefinite number of times.
1123 \item [Run = \lt{}job-name\gt{}]
1124 \index[dir]{Run directive}
1125 \index[dir]{Clone a Job}
1126 The Run directive (not to be confused with the Run option in a
1127 Schedule) allows you to clone jobs and thus, if you want backup
1128 the same data (or almost the same data) to two or more drives
1129 at the same time. The {\bf job-name} is normally the same name
1130 as the current Job resource (thus creating a clone). However, it
1131 may be any Job name, so one job may start other related jobs.
1133 The part after the equal sign must be enclosed in double quotes,
1134 and can contain any string or set of options (overrides) that you
1135 can specify when entering the Run command from the console. For
1136 example {\bf storage=DDS-4 ...}. In addition, there are two special
1137 keywords that permit you to clone the current job. They are {\bf level=\%l}
1138 and {\bf since=\%s}. The \%l in the level keyword permits
1139 entering the actual level of the current job and the \%s in the since
1140 keyword permits putting the same time for comparison as used on the
1141 current job. Note, in the case of the since keyword, the \%s must be
1142 enclosed in double quotes, and thus they must be preceded by a backslash
1143 since they are already inside quotes. For example:
1146 run = "Nightly-backup level=%s since=\"%s\" storage=DDS-4"
1150 A cloned job will not start additional clones, so it is not
1151 possible to recurse.
1156 \item [Priority = \lt{}number\gt{}]
1157 \index[dir]{Priority }
1158 This directive permits you to control the order in which your jobs run
1159 by specifying a positive non-zero number. The higher the number, the
1160 lower the job priority. Assuming you are not running concurrent jobs,
1161 all queued jobs of priority 1 will run before queued jobs of priority 2
1162 and so on, regardless of the original scheduling order.
1164 The priority only affects waiting jobs that are queued to run, not jobs
1165 that are already running. If one or more jobs of priority 2 are already
1166 running, and a new job is scheduled with priority 1, the currently
1167 running priority 2 jobs must complete before the priority 1 job is run.
1169 The default priority is 10.
1171 If you want to run concurrent jobs, which is not recommended, you should
1173 these points in mind:
1176 \item To run concurrent jobs, you must set Maximum Concurrent Jobs = 2 in 5
1177 or 6 distinct places: in bacula-dir.conf in the Director, the Job, the
1178 Client, the Storage resources; in bacula-fd in the FileDaemon (or Client)
1179 resource, and in bacula-sd.conf in the Storage resource. If any one is
1180 missing, it will throttle the jobs to one at a time.
1181 \item Bacula concurrently runs jobs of only one priority at a time. It will
1182 not simultaneously run a priority 1 and a priority 2 job.
1183 \item If Bacula is running a priority 2 job and a new priority 1 job is
1184 scheduled, it will wait until the running priority 2 job terminates even if
1185 the Maximum Concurrent Jobs settings would otherwise allow two jobs to run
1187 \item Suppose that bacula is running a priority 2 job and a new priority 1 job
1188 is scheduled and queued waiting for the running priority 2 job to terminate.
1189 If you then start a second priority 2 job, the waiting priority 1 job will
1190 prevent the new priority 2 job from running concurrently with the running
1191 priority 2 job. That is: as long as there is a higher priority job waiting
1193 run, no new lower priority jobs will start even if the Maximum Concurrent
1194 Jobs settings would normally allow them to run. This ensures that higher
1195 priority jobs will be run as soon as possible.
1198 If you have several jobs of different priority, it may not best to start
1199 them at exactly the same time, because Bacula must examine them one at a
1200 time. If by Bacula starts a lower priority job first, then it will run
1201 before your high priority jobs. If you experience this problem, you may
1202 avoid it by starting any higher priority jobs a few seconds before lower
1203 priority ones. This insures that Bacula will examine the jobs in the
1204 correct order, and that your priority scheme will be respected.
1206 \label{WritePartAfterJob}
1207 \item [Write Part After Job = \lt{}yes|no\gt{}]
1208 \index[dir]{Write Part After Job }
1209 This directive is only implemented in version 1.37 and later.
1210 If this directive is set to {\bf yes} (default {\bf no}), a new part file
1211 will be created after the job is finished.
1213 It should be set to {\bf yes} when writing to devices that require mount
1214 (for example DVD), so you are sure that the current part, containing
1215 this job's data, is written to the device, and that no data is left in
1216 the temporary file on the hard disk. However, on some media, like DVD+R
1217 and DVD-R, a lot of space (about 10Mb) is lost everytime a part is
1218 written. So, if you run several jobs each after another, you could set
1219 this directive to {\bf no} for all jobs, except the last one, to avoid
1220 wasting too much space, but to ensure that the data is written to the
1221 medium when all jobs are finished.
1223 It is ignored with tape and FIFO devices.
1226 The following is an example of a valid Job resource definition:
1233 Level = Incremental # default
1235 FileSet="Minou Full Set"
1238 Schedule = "MinouWeeklyCycle"

1246 \index[general]{JobDefs Resource}
1247 \index[general]{Resource!JobDefs}
1248 \addcontentsline{toc}{subsection}{JobDefs Resource}
1250 The JobDefs resource permits all the same directives that can appear in a Job
1251 resource. However, a JobDefs resource does not create a Job, rather it can be
1252 referenced within a Job to provide defaults for that Job. This permits you to
1253 concisely define several nearly identical Jobs, each one referencing a JobDefs
1254 resource which contains the defaults. Only the changes from the defaults need to
1255 be mentioned in each Job.
1257 \subsection*{The Schedule Resource}
1258 \label{ScheduleResource}
1259 \index[general]{Resource!Schedule}
1260 \index[general]{Schedule Resource}
1261 \addcontentsline{toc}{subsection}{Schedule Resource}
1263 The Schedule resource provides a means of automatically scheduling a Job as
1264 well as the ability to override the default Level, Pool, Storage and Messages
1265 resources. If a Schedule resource is not referenced in a Job, the Job can only
1266 be run manually. In general, you specify an action to be taken and when.
1271 \index[dir]{Schedule}
1272 Start of the Schedule directives. No {\bf Schedule} resource is required,
1274 you will need at least one if you want Jobs to be automatically started.
1276 \item [Name = \lt{}name\gt{}]
1278 The name of the schedule being defined. The Name directive is required.
1280 \item [Run = \lt{}Job-overrides\gt{} \lt{}Date-time-specification\gt{}]
1282 The Run directive defines when a Job is to be run, and what overrides if any
1283 to apply. You may specify multiple {\bf run} directives within a {\bf
1284 Schedule} resource. If you do, they will all be applied (i.e. multiple
1285 schedules). If you have two {\bf Run} directives that start at the same time,
1286 two Jobs will start at the same time (well, within one second of each
1289 The {\bf Job-overrides} permit overriding the Level, the Storage, the
1290 Messages, and the Pool specifications provided in the Job resource. In
1291 addition, the FullPool, the IncrementalPool, and the DifferentialPool
1292 specifications permit overriding the Pool specification according to what
1293 backup Job Level is in effect.
1295 By the use of overrides, you may customize a particular Job. For example, you
1296 may specify a Messages override for your Incremental backups that outputs
1297 messages to a log file, but for your weekly or monthly Full backups, you may
1298 send the output by email by using a different Messages override.
1300 {\bf Job-overrides} are specified as: {\bf keyword=value} where the keyword
1301 is Level, Storage, Messages, Pool, FullPool, DifferentialPool, or
1302 IncrementalPool, and the {\bf value} is as defined on the respective
1303 directive formats for the Job resource. You may specify multiple {\bf
1304 Job-overrides} on one {\bf Run} directive by separating them with one or more
1305 spaces or by separating them with a trailing comma. For example:
1311 is all files in the FileSet whether or not they have changed.
1313 \item [Level=Incremental]
1315 is all files that have changed since the last backup.
1319 specifies to use the Pool named {\bf Weekly}.
1321 \item [Storage=DLT\_Drive]
1322 \index[dir]{Storage}
1323 specifies to use {\bf DLT\_Drive} for the storage device.
1325 \item [Messages=Verbose]
1326 \index[dir]{Messages}
1327 specifies to use the {\bf Verbose} message resource for the Job.
1329 \item [FullPool=Full]
1330 \index[dir]{FullPool}
1331 specifies to use the Pool named {\bf Full} if the job is a full backup, or
1333 upgraded from another type to a full backup.
1335 \item [DifferentialPool=Differential]
1336 \index[dir]{DifferentialPool}
1337 specifies to use the Pool named {\bf Differential} if the job is a
1338 differential backup.
1340 \item [IncrementalPool=Incremental]
1341 \index[dir]{IncrementalPool}
1342 specifies to use the Pool named {\bf Incremental} if the job is an
1345 \item [SpoolData=yes|no]
1346 \index[dir]{SpoolData}
1347 tells Bacula to request the Storage daemon to spool data to a disk file
1348 before putting it on tape.
1350 \item [WritePartAfterJob=yes|no]
1351 \index[dir]{WritePartAfterJob}
1352 tells Bacula to request the Storage daemon to write the current part file to
1353 the device when the job is finished (see
1354 \ilink{Write Part After Job directive in the Job
1355 resource}{WritePartAfterJob}). Please note, this directive is implemented
1356 only in version 1.37 and later.
1360 {\bf Date-time-specification} determines when the Job is to be run. The
1361 specification is a repetition, and as a default Bacula is set to run a job at
1362 the beginning of the hour of every hour of every day of every week of every
1363 month of every year. This is not normally what you want, so you must specify
1364 or limit when you want the job to run. Any specification given is assumed to
1365 be repetitive in nature and will serve to override or limit the default
1366 repetition. This is done by specifying masks or times for the hour, day of the
1367 month, day of the week, week of the month, week of the year, and month when
1368 you want the job to run. By specifying one or more of the above, you can
1369 define a schedule to repeat at almost any frequency you want.
1371 Basically, you must supply a {\bf month}, {\bf day}, {\bf hour}, and {\bf
1372 minute} the Job is to be run. Of these four items to be specified, {\bf day}
1373 is special in that you may either specify a day of the month such as 1, 2,
1374 ... 31, or you may specify a day of the week such as Monday, Tuesday, ...
1375 Sunday. Finally, you may also specify a week qualifier to restrict the
1376 schedule to the first, second, third, fourth, or fifth week of the month.
1378 For example, if you specify only a day of the week, such as {\bf Tuesday} the
1379 Job will be run every hour of every Tuesday of every Month. That is the {\bf
1380 month} and {\bf hour} remain set to the defaults of every month and all
1383 Note, by default with no other specification, your job will run at the
1384 beginning of every hour. If you wish your job to run more than once in any
1385 given hour, you will need to specify multiple {\bf run} specifications each
1386 with a different minute.
1388 The date/time to run the Job can be specified in the following way in
1395 <week-keyword> = 1st | 2nd | 3rd | 4th | 5th | first |
1396 second | third | forth | fifth
1397 <wday-keyword> = sun | mon | tue | wed | thu | fri | sat |

1434 <month-spec> = <month-keyword> | <month-range> |
1436 <date-time-spec> = <month-spec> <day-spec> <time-spec>
1442 Note, the Week of Year specification wnn follows the ISO standard definition
1443 of the week of the year, where Week 1 is the week in which the first Thursday
1444 of the year occurs, or alternatively, the week which contains the 4th of
1445 January. Weeks are numbered w01 to w53. w00 for Bacula is the week that
1446 precedes the first ISO week (i.e. has the first few days of the year if any
1447 occur before Thursday). w00 is not defined by the ISO specification. A week
1448 starts with Monday and ends with Sunday.
1450 An example schedule resource that is named {\bf WeeklyCycle} and runs a job
1451 with level full each Sunday at 1:05am and an incremental job Monday through
1452 Saturday at 1:05am is:
1457 Name = "WeeklyCycle"
1458 Run = Level=Full sun at 1:05
1459 Run = Level=Incremental mon-sat at 1:05
1464 An example of a possible monthly cycle is as follows:
1469 Name = "MonthlyCycle"
1470 Run = Level=Full Pool=Monthly 1st sun at 1:05
1471 Run = Level=Differential 2nd-5th sun at 1:05
1472 Run = Level=Incremental Pool=Daily mon-sat at 1:05
1477 The first of every month:
1483 Run = Level=Full on 1 at 1:05
1484 Run = Level=Incremental on 2-31 at 1:05
1495 Run = Level=Full hourly at 0:05
1496 Run = Level=Full hourly at 0:15
1497 Run = Level=Full hourly at 0:25
1498 Run = Level=Full hourly at 0:35
1499 Run = Level=Full hourly at 0:45

1508 \addcontentsline{toc}{subsection}{Technical Notes on Schedules}
1510 Internally Bacula keeps a schedule as a bit mask. There are six masks and a
1511 minute field to each schedule. The masks are hour, day of the month (mday),
1512 month, day of the week (wday), week of the month (wom), and week of the year
1513 (woy). The schedule is initialized to have the bits of each of these masks
1514 set, which means that at the beginning of every hour, the job will run. When
1515 you specify a month for the first time, the mask will be cleared and the bit
1516 corresponding to your selected month will be selected. If you specify a second
1517 month, the bit corresponding to it will also be added to the mask. Thus when
1518 Bacula checks the masks to see if the bits are set corresponding to the
1519 current time, your job will run only in the two months you have set. Likewise,
1520 if you set a time (hour), the hour mask will be cleared, and the hour you
1521 specify will be set in the bit mask and the minutes will be stored in the
1524 For any schedule you have defined, you can see how these bits are set by doing
1525 a {\bf show schedules} command in the Console program. Please note that the
1526 bit mask is zero based, and Sunday is the first day of the week (bit zero).

1532 \index[general]{Resource!Client}
1533 \index[general]{Client Resource}
1534 \addcontentsline{toc}{subsection}{Client Resource}
1536 The Client resource defines the attributes of the Clients that are served by
1537 this Director; that is the machines that are to be backed up. You will need
1538 one Client resource definition for each machine to be backed up.
1542 \item [Client (or FileDaemon)]
1543 \index[dir]{Client (or FileDaemon)}
1544 Start of the Client directives.
1546 \item [Name = \lt{}name\gt{}]
1548 The client name which will be used in the Job resource directive or in the
1549 console run command. This directive is required.
1551 \item [Address = \lt{}address\gt{}]
1552 \index[dir]{Address }
1553 Where the address is a host name, a fully qualified domain name, or a
1555 address in dotted quad notation for a Bacula File server daemon. This
1556 directive is required.
1558 \item [FD Port = \lt{}port-number\gt{}]
1559 \index[dir]{FD Port }
1560 Where the port is a port number at which the Bacula File server daemon can
1562 contacted. The default is 9102.
1564 \item [Catalog = \lt{}Catalog-resource-name\gt{}]
1565 \index[dir]{Catalog }
1566 This specifies the name of the catalog resource to be used for this Client.
1567 This directive is required.
1569 \item [Password = \lt{}password\gt{}]
1570 \index[dir]{Password }
1571 This is the password to be used when establishing a connection with the File
1572 services, so the Client configuration file on the machine to be backed up
1573 must have the same password defined for this Director. This directive is
1574 required. If you have either {\bf /dev/random} {\bf bc} on your machine,
1575 Bacula will generate a random password during the configuration process,
1576 otherwise it will be left blank.
1577 \label{FileRetention}
1579 \item [File Retention = \lt{}time-period-specification\gt{}]
1580 \index[dir]{File Retention }
1581 The File Retention directive defines the length of time that Bacula will
1583 File records in the Catalog database. When this time period expires, and if
1584 {\bf AutoPrune} is set to {\bf yes} Bacula will prune (remove) File records
1585 that are older than the specified File Retention period. Note, this affects
1586 only records in the catalog database. It does not affect your archive
1589 File records may actually be retained for a shorter period than you specify
1590 on this directive if you specify either a shorter {\bf Job Retention} or a
1591 shorter {\bf Volume Retention} period. The shortest retention period of the
1592 three takes precedence. The time may be expressed in seconds, minutes,
1593 hours, days, weeks, months, quarters, or years. See the
1594 \ilink{ Configuration chapter}{Time} of this manual for
1595 additional details of time specification.
1597 The default is 60 days.
1598 \label{JobRetention}
1600 \item [Job Retention = \lt{}time-period-specification\gt{}]
1601 \index[dir]{Job Retention }
1602 The Job Retention directive defines the length of time that Bacula will keep
1603 Job records in the Catalog database. When this time period expires, and if
1604 {\bf AutoPrune} is set to {\bf yes} Bacula will prune (remove) Job records
1605 that are older than the specified File Retention period. As with the other
1606 retention periods, this affects only records in the catalog and not data in
1607 your archive backup.
1609 If a Job record is selected for pruning, all associated File and JobMedia
1610 records will also be pruned regardless of the File Retention period set.
1611 As a consequence, you normally will set the File retention period to be
1612 less than the Job retention period. The Job retention period can actually
1613 be less than the value you specify here if you set the {\bf Volume
1614 Retention} directive in the Pool resource to a smaller duration. This is
1615 because the Job retention period and the Volume retention period are
1616 independently applied, so the smaller of the two takes precedence.
1618 The Job retention period is specified as seconds, minutes, hours, days,
1619 weeks, months, quarters, or years. See the
1620 \ilink{ Configuration chapter}{Time} of this manual for
1621 additional details of time specification.
1623 The default is 180 days.
1626 \item [AutoPrune = \lt{}yes|no\gt{}]
1627 \index[dir]{AutoPrune }
1628 If AutoPrune is set to {\bf yes} (default), Bacula (version 1.20 or greater)
1629 will automatically apply the File retention period and the Job retention
1630 period for the Client at the end of the Job. If you set {\bf AutoPrune = no},
1631 pruning will not be done, and your Catalog will grow in size each time you
1632 run a Job. Pruning affects only information in the catalog and not data
1633 stored in the backup archives (on Volumes).
1635 \item [Maximum Concurrent Jobs = \lt{}number\gt{}]
1636 \index[dir]{Maximum Concurrent Jobs }
1637 where \lt{}number\gt{} is the maximum number of Jobs with the current Client
1638 that can run concurrently. Note, this directive limits only Jobs for Clients
1639 with the same name as the resource in which it appears. Any other
1640 restrictions on the maximum concurrent jobs such as in the Director, Job, or
1641 Storage resources will also apply in addition to any limit specified here.
1642 The default is set to 1, but you may set it to a larger number. We strongly
1643 recommend that you read the WARNING documented under
1644 \ilink{ Maximum Concurrent Jobs}{DirMaxConJobs} in the Director's
1647 \item [*Priority = \lt{}number\gt{}]
1648 \index[dir]{*Priority }
1649 The number specifies the priority of this client relative to other clients
1650 that the Director is processing simultaneously. The priority can range from
1651 1 to 1000. The clients are ordered such that the smaller number priorities
1652 are performed first (not currently implemented).
1655 The following is an example of a valid Client resource definition:
1663 Password = very_good

1669 \label{StorageResource2}
1670 \index[general]{Resource!Storage}
1671 \index[general]{Storage Resource}
1672 \addcontentsline{toc}{subsection}{Storage Resource}
1674 The Storage resource defines which Storage daemons are available for use by
1680 \index[dir]{Storage}
1681 Start of the Storage resources. At least one storage resource must be
1684 \item [Name = \lt{}name\gt{}]
1686 The name of the storage resource. This name appears on the Storage directive
1687 specified in the Job directive and is required.
1689 \item [Address = \lt{}address\gt{}]
1690 \index[dir]{Address }
1691 Where the address is a host name, a {\bf fully qualified domain name}, or an
1692 {\bf IP address}. Please note that the \lt{}address\gt{} as specified here
1693 will be transmitted to the File daemon who will then use it to contact the
1694 Storage daemon. Hence, it is {\bf not}, a good idea to use {\bf localhost} as
1695 the name but rather a fully qualified machine name or an IP address. This
1696 directive is required.
1698 \item [SD Port = \lt{}port\gt{}]
1699 \index[dir]{SD Port }
1700 Where port is the port to use to contact the storage daemon for information
1701 and to start jobs. This same port number must appear in the Storage resource
1702 of the Storage daemon's configuration file. The default is 9103.
1704 \item [Password = \lt{}password\gt{}]
1705 \index[dir]{Password }
1706 This is the password to be used when establishing a connection with the
1707 Storage services. This same password also must appear in the Director
1708 resource of the Storage daemon's configuration file. This directive is
1709 required. If you have either {\bf /dev/random} {\bf bc} on your machine,
1710 Bacula will generate a random password during the configuration process,
1711 otherwise it will be left blank.
1713 \item [Device = \lt{}device-name\gt{}]
1714 \index[dir]{Device }
1715 This directive specifies the name of the device to be used for the
1716 storage. This name is not the physical device name, but the logical device
1717 name as defined on the {\bf Name} directive contained in the {\bf Device}
1718 resource definition of the {\bf Storage daemon} configuration file or if
1719 the device is an Autochanger, you must put the name as defined on the {\bf Name}
1720 directive contained in the {\bf Autochanger resource definition of the {\bf
1721 Storage daemon}. You can specify any name you would like (even the device name
1722 if you prefer) up to a
1723 maximum of 127 characters in length. The physical device name associated with
1724 this device is specified in the {\bf Storage daemon} configuration file (as
1725 {\bf Archive Device}). Please take care not to define two different Storage
1726 resource directives in the Director that point to the same Device in the
1727 Storage daemon. Doing so may cause the Storage daemon to block (or hang)
1728 attempting to open the same device that is already open. This directive is
1731 \item [Media Type = \lt{}MediaType\gt{}]
1732 \index[dir]{Media Type }
1733 This directive specifies the Media Type to be used to store the data. This
1735 an arbitrary string of characters up to 127 maximum that you define. It can
1736 be anything you want. However, it is best to make it descriptive of the
1737 storage media (e.g. File, DAT, "HP DLT8000", 8mm, ...). In addition, it is
1738 essential that you make the {\bf Media Type} specification unique for each
1739 storage media type. If you have two DDS-4 drives that have incompatible
1740 formats, or if you have a DDS-4 drive and a DDS-4 autochanger, you almost
1741 certainly should specify different {\bf Media Types}. During a restore,
1742 assuming a {\bf DDS-4} Media Type is associated with the Job, Bacula can
1743 decide to use any Storage daemon that support Media Type {\bf DDS-4} and on
1744 any drive that supports it. If you want to tie Bacula to using a single Storage
1745 daemon or drive, you must specify a unique Media Type for that drive. This is
1746 an important point that should be carefully understood. You can find more on
1748 \ilink{Basic Volume Management}{_ChapterStart39} chapter of this
1751 The {\bf MediaType} specified here, {\bf must} correspond to the {\bf Media
1752 Type} specified in the {\bf Device} resource of the {\bf Storage daemon}
1753 configuration file. This directive is required, and it is used by the
1754 Director and the Storage daemon to ensure that a Volume automatically
1755 selected from the Pool corresponds to the physical device. If a Storage
1756 daemon handles multiple devices (e.g. will write to various file Volumes on
1757 different partitions), this directive allows you to specify exactly which
1760 As mentioned above, the value specified in the Director's Storage resource
1761 must agree with the value specified in the Device resource in the {\bf
1762 Storage daemon's} configuration file. It is also an additional check so that
1763 you don't try to write data for a DLT onto an 8mm device.
1765 \label{Autochanger1}
1766 \item [Autochanger = \lt{}yes|no\gt{}]
1767 \index[dir]{Autochanger }
1768 If you specify {\bf yes} for this command (the default is {\bf no}), when
1770 use the {\bf label} command or the {\bf add} command to create a new Volume,
1771 {\bf Bacula} will also request the Autochanger Slot number. This simplifies
1772 creating database entries for Volumes in an autochanger. If you forget to
1773 specify the Slot, the autochanger will not be used. However, you may modify
1774 the Slot associated with a Volume at any time by using the {\bf update
1775 volume} command in the console program. When {\bf autochanger} is enabled,
1776 the algorithm used by Bacula to search for available volumes will be modified
1777 to consider only Volumes that are known to be in the autochanger's magazine.
1778 If no {\bf in changer} volume is found, Bacula will attempt recycling,
1779 pruning, ..., and if still no volume is found, Bacula will search for any
1780 volume whether or not in the magazine. By privileging in changer volumes,
1781 this procedure minimizes operator intervention. The default is {\bf no}.
1783 For the autochanger to be used, you must also specify {\bf Autochanger = yes}
1785 \ilink{Device Resource}{Autochanger} in the Storage daemon's
1786 configuration file as well as other important Storage daemon configuration
1787 information. Please consult the

1791 \item [Maximum Concurrent Jobs = \lt{}number\gt{}]
1792 \index[dir]{Maximum Concurrent Jobs }
1793 where \lt{}number\gt{} is the maximum number of Jobs with the current
1795 resource that can run concurrently. Note, this directive limits only Jobs
1796 for Jobs using this Storage daemon. Any other restrictions on the maximum
1797 concurrent jobs such as in the Director, Job, or Client resources will also
1798 apply in addition to any limit specified here. The default is set to 1, but
1799 you may set it to a larger number. We strongly recommend that you read the
1800 WARNING documented under
1801 \ilink{ Maximum Concurrent Jobs}{DirMaxConJobs} in the Director's
1804 While it is possible to set the Director's, Job's, or Client's maximum
1805 concurrent jobs greater than one, you should take great care in setting the
1806 Storage daemon's greater than one. By keeping this directive set to one, you
1807 will avoid having two jobs simultaneously write to the same Volume. Although
1808 this is supported, it is not currently recommended.
1811 The following is an example of a valid Storage resource definition:
1815 # Definition of tape storage device
1819 Password = storage_password # password for Storage daemon
1820 Device = "HP DLT 80" # same as Device in Storage daemon
1821 Media Type = DLT8000 # same as MediaType in Storage daemon

1827 \label{PoolResource}
1828 \index[general]{Resource!Pool}
1829 \index[general]{Pool Resource}
1830 \addcontentsline{toc}{subsection}{Pool Resource}
1832 The Pool resource defines the set of storage Volumes (tapes or files) to be
1833 used by Bacula to write the data. By configuring different Pools, you can
1834 determine which set of Volumes (media) receives the backup data. This permits,
1835 for example, to store all full backup data on one set of Volumes and all
1836 incremental backups on another set of Volumes. Alternatively, you could assign
1837 a different set of Volumes to each machine that you backup. This is most
1838 easily done by defining multiple Pools.
1840 Another important aspect of a Pool is that it contains the default attributes
1841 (Maximum Jobs, Retention Period, Recycle flag, ...) that will be given to a
1842 Volume when it is created. This avoids the need for you to answer a large
1843 number of questions when labeling a new Volume. Each of these attributes can
1844 later be changed on a Volume by Volume basis using the {\bf update} command in
1845 the console program. Note that you must explicitly specify which Pool Bacula
1846 is to use with each Job. Bacula will not automatically search for the correct
1849 Most often in Bacula installations all backups for all machines (Clients) go
1850 to a single set of Volumes. In this case, you will probably only use the {\bf
1851 Default} Pool. If your backup strategy calls for you to mount a different tape
1852 each day, you will probably want to define a separate Pool for each day. For
1853 more information on this subject, please see the
1854 \ilink{Backup Strategies}{_ChapterStart3} chapter of this
1858 To use a Pool, there are three distinct steps. First the Pool must be defined
1859 in the Director's configuration file. Then the Pool must be written to the
1860 Catalog database. This is done automatically by the Director each time that it
1861 starts, or alternatively can be done using the {\bf create} command in the
1862 console program. Finally, if you change the Pool definition in the Director's
1863 configuration file and restart Bacula, the pool will be updated alternatively
1864 you can use the {\bf update pool} console command to refresh the database
1865 image. It is this database image rather than the Director's resource image
1866 that is used for the default Volume attributes. Note, for the pool to be
1867 automatically created or updated, it must be explicitly referenced by a Job
1870 Next the physical media must be labeled. The labeling can either be done with
1871 the {\bf label} command in the {\bf console} program or using the {\bf btape}
1872 program. The preferred method is to use the {\bf label} command in the {\bf
1875 Finally, you must add Volume names (and their attributes) to the Pool. For
1876 Volumes to be used by Bacula they must be of the same {\bf Media Type} as the
1877 archive device specified for the job (i.e. if you are going to back up to a
1878 DLT device, the Pool must have DLT volumes defined since 8mm volumes cannot be
1879 mounted on a DLT drive). The {\bf Media Type} has particular importance if you
1880 are backing up to files. When running a Job, you must explicitly specify which
1881 Pool to use. Bacula will then automatically select the next Volume to use from
1882 the Pool, but it will ensure that the {\bf Media Type} of any Volume selected
1883 from the Pool is identical to that required by the Storage resource you have
1884 specified for the Job.
1886 If you use the {\bf label} command in the console program to label the
1887 Volumes, they will automatically be added to the Pool, so this last step is
1888 not normally required.
1890 It is also possible to add Volumes to the database without explicitly labeling
1891 the physical volume. This is done with the {\bf add} console command.
1893 As previously mentioned, each time Bacula starts, it scans all the Pools
1894 associated with each Catalog, and if the database record does not already
1895 exist, it will be created from the Pool Resource definition. {\bf Bacula}
1896 probably should do an {\bf update pool} if you change the Pool definition, but
1897 currently, you must do this manually using the {\bf update pool} command in
1898 the Console program.
1900 The Pool Resource defined in the Director's configuration file
1901 (bacula-dir.conf) may contain the following directives:
1907 Start of the Pool resource. There must be at least one Pool resource
1911 \item [Name = \lt{}name\gt{}]
1913 The name of the pool. For most applications, you will use the default pool
1914 name {\bf Default}. This directive is required.
1916 \item [Number of Volumes = \lt{}number\gt{}]
1917 \index[dir]{Number of Volumes }
1918 This directive specifies the number of volumes (tapes or files) contained in
1919 the pool. Normally, it is defined and updated automatically by the Bacula
1920 catalog handling routines.
1923 \item [Maximum Volumes = \lt{}number\gt{}]
1924 \index[dir]{Maximum Volumes }
1925 This directive specifies the maximum number of volumes (tapes or files)
1926 contained in the pool. This directive is optional, if omitted or set to zero,
1927 any number of volumes will be permitted. In general, this directive is useful
1928 for Autochangers where there is a fixed number of Volumes, or for File
1929 storage where you wish to ensure that the backups made to disk files do not
1930 become too numerous or consume too much space.
1932 \item [Pool Type = \lt{}type\gt{}]
1933 \index[dir]{Pool Type }
1934 This directive defines the pool type, which corresponds to the type of Job
1935 being run. It is required and may be one of the following:
1946 \item [Use Volume Once = \lt{}yes|no\gt{}]
1947 \index[dir]{Use Volume Once }
1948 This directive if set to {\bf yes} specifies that each volume is to be used
1949 only once. This is most useful when the Media is a file and you want a new
1950 file for each backup that is done. The default is {\bf no} (i.e. use volume
1951 any number of times). This directive will most likely be phased out
1952 (deprecated), so you are recommended to use {\bf Maximum Volume Jobs = 1}
1955 Please note that the value defined by this directive in the bacula-dir.conf
1956 file is the default value used when a Volume is created. Once the volume is
1957 created, changing the value in the bacula-dir.conf file will not change what
1958 is stored for the Volume. To change the value for an existing Volume you
1959 must use the {\bf update} command in the Console.
1961 \item [Maximum Volume Jobs = \lt{}positive-integer\gt{}]
1962 \index[dir]{Maximum Volume Jobs }
1963 This directive specifies the maximum number of Jobs that can be written to
1964 the Volume. If you specify zero (the default), there is no limit. Otherwise,
1965 when the number of Jobs backed up to the Volume equals {\bf positive-integer}
1966 the Volume will be marked {\bf Used}. When the Volume is marked {\bf Used} it
1967 can no longer be used for appending Jobs, much like the {\bf Full} status but
1968 it can be recycled if recycling is enabled, and thus used again.
1970 MaximumVolumeJobs} to one, you get the same effect as setting {\bf
1971 UseVolumeOnce = yes}.
1973 Please note that the value defined by this directive in the bacula-dir.conf
1974 file is the default value used when a Volume is created. Once the volume is
1975 created, changing the value in the bacula-dir.conf file will not change what
1976 is stored for the Volume. To change the value for an existing Volume you
1977 must use the {\bf update} command in the Console.
1979 \item [Maximum Volume Files = \lt{}positive-integer\gt{}]
1980 \index[dir]{Maximum Volume Files }
1981 This directive specifies the maximum number of files that can be written to
1982 the Volume. If you specify zero (the default), there is no limit. Otherwise,
1983 when the number of files written to the Volume equals {\bf positive-integer}
1984 the Volume will be marked {\bf Used}. When the Volume is marked {\bf Used} it
1985 can no longer be used for appending Jobs, much like the {\bf Full} status but
1986 it can be recycled if recycling is enabled and thus used again.
1987 This value is checked and the
1988 {\bf Used} status is set only at the end of a job that writes to the
1991 Please note that the value defined by this directive in the bacula-dir.conf
1992 file is the default value used when a Volume is created. Once the volume is
1993 created, changing the value in the bacula-dir.conf file will not change what
1994 is stored for the Volume. To change the value for an existing Volume you
1995 must use the {\bf update} command in the Console.
1997 \item [Maximum Volume Bytes = \lt{}size\gt{}]
1998 \index[dir]{Maximum Volume Bytes }
1999 This directive specifies the maximum number of bytes that can be written to
2000 the Volume. If you specify zero (the default), there is no limit except the
2001 physical size of the Volume. Otherwise, when the number of bytes written to
2002 the Volume equals {\bf size} the Volume will be marked {\bf Used}. When the
2003 Volume is marked {\bf Used} it can no longer be used for appending Jobs, much
2004 like the {\bf Full} status but it can be recycled if recycling is enabled,
2005 and thus the Volume can be re-used after recycling.
2006 This value is checked and the {\bf Used} status set while the job is writing
2007 to the particular volume.
2009 Please note that the value defined by this directive in the bacula-dir.conf
2010 file is the default value used when a Volume is created. Once the volume is
2011 created, changing the value in the bacula-dir.conf file will not change what
2012 is stored for the Volume. To change the value for an existing Volume you
2013 must use the {\bf update} command in the Console.
2015 \item [Volume Use Duration = \lt{}time-period-specification\gt{}]
2016 \index[dir]{Volume Use Duration }
2017 The Volume Use Duration directive defines the time period that the
2018 Volume can be written beginning from the time of first data write to the
2019 Volume. If the time-period specified is zero (the default), the Volume
2020 can be written indefinitely. Otherwise, when the time period from the
2021 first write to the volume (the first Job written) exceeds the
2022 time-period-specification, the Volume will be marked {\bf Used}, which
2023 means that no more Jobs can be appended to the Volume, but it may be
2024 recycled if recycling is enabled. Once the Volume is
2025 recycled, it will be available for use again.
2027 You might use this directive, for example, if you have a Volume used for
2028 Incremental backups, and Volumes used for Weekly Full backups. Once the
2029 Full backup is done, you will want to use a different Incremental
2030 Volume. This can be accomplished by setting the Volume Use Duration for
2031 the Incremental Volume to six days. I.e. it will be used for the 6
2032 days following a Full save, then a different Incremental volume will be
2033 used. Be careful about setting the duration to short periods such as 23
2034 hours, or you might experience problems of Bacula waiting for a tape
2035 over the weekend only to complete the backups Monday morning when an
2036 operator mounts a new tape.
2038 The use duration is checked and the {\bf Used} status is set only at the
2039 end of a job that writes to the particular volume, which means that even
2040 though the use duration may have expired, the catalog entry will not be
2041 updated until the next job that uses this volume is run.
2043 Please note that the value defined by this directive in the bacula-dir.conf
2044 file is the default value used when a Volume is created. Once the volume is
2045 created, changing the value in the bacula-dir.conf file will not change what
2046 is stored for the Volume. To change the value for an existing Volume you
2048 \ilink{\bf update volume}{UpdateCommand} command in the Console.
2050 \item [Catalog Files = \lt{}yes|no\gt{}]
2051 \index[dir]{Catalog Files }
2052 This directive defines whether or not you want the names of the files
2053 that were saved to be put into the catalog. The default is {\bf yes}.
2054 The advantage of specifying {\bf Catalog Files = No} is that you will
2055 have a significantly smaller Catalog database. The disadvantage is that
2056 you will not be able to produce a Catalog listing of the files backed up
2057 for each Job (this is often called Browsing). Also, without the File
2058 entries in the catalog, you will not be able to use the Console {\bf
2059 restore} command nor any other command that references File entries.
2061 \label{PoolAutoPrune}
2062 \item [AutoPrune = \lt{}yes|no\gt{}]
2063 \index[dir]{AutoPrune }
2064 If AutoPrune is set to {\bf yes} (default), Bacula (version 1.20 or greater)
2065 will automatically apply the Volume Retention period when new Volume is
2066 needed and no appendable Volumes exist in the Pool. Volume pruning causes
2067 expired Jobs (older than the {\bf Volume Retention} period) to be deleted
2068 from the Catalog and permits possible recycling of the Volume.
2070 \label{VolRetention}
2071 \item [Volume Retention = \lt{}time-period-specification\gt{}]
2072 \index[dir]{Volume Retention }
2073 The Volume Retention directive defines the length of time that {\bf
2074 Bacula} will keep Job records associated with the Volume in the Catalog
2075 database. When this time period expires, and if {\bf AutoPrune} is set
2076 to {\bf yes} Bacula may prune (remove) Job records that are older than
2077 the specified Volume Retention period if it is necessary to free up a
2078 Volume. Recycling will not occur until it is absolutely necessary to
2079 free up a volume. All File records associated with pruned Jobs are also
2080 pruned. The time may be specified as seconds, minutes, hours, days,
2081 weeks, months, quarters, or years. The {\bf Volume Retention} is
2082 applied independently of the {\bf Job Retention} and the {\bf File
2083 Retention} periods defined in the Client resource. This means that all
2084 the retentions periods are applied in turn and that the shorter period
2085 is the one that effectively takes precedence. Note, that when the {\bf
2086 Volume Retention} period has been reached, and it is necessary to obtain
2087 a new volume, Bacula will prune both the Job and the File records.
2089 It is important to know that when the Volume Retention period expires,
2090 Bacula does not automatically recycle a Volume. It attempts to keep the
2091 Volume data intact as long as possible before over writing the Volume.
2093 The default Volume retention period is 365 days. Note, this directive
2094 sets the default value for each Volume entry in the Catalog when the
2095 Volume is created. The value in the catalog may be later individually
2096 changed for each Volume using the Console program.
2098 By defining multiple Pools with different Volume Retention periods, you
2099 may effectively have a set of tapes that is recycled weekly, another
2100 Pool of tapes that is recycled monthly and so on. However, one must
2101 keep in mind that if your {\bf Volume Retention} period is too short, it
2102 may prune the last valid Full backup, and hence until the next Full
2103 backup is done, you will not have a complete backup of your system, and
2104 in addition, the next Incremental or Differential backup will be
2105 promoted to a Full backup. As a consequence, the minimum {\bf Volume
2106 Retention} period should be at twice the interval of your Full backups.
2107 This means that if you do a Full backup once a month, the minimum Volume
2108 retention period should be two months.
2110 Please note that the value defined by this directive in the bacula-dir.conf
2111 file is the default value used when a Volume is created. Once the volume is
2112 created, changing the value in the bacula-dir.conf file will not change what
2113 is stored for the Volume. To change the value for an existing Volume you
2114 must use the {\bf update} command in the Console.
2117 \item [Recycle = \lt{}yes|no\gt{}]
2118 \index[dir]{Recycle }
2119 This directive specifies whether or not Purged Volumes will be recycled.
2120 If it is set to {\bf yes} (default) and Bacula needs a volume but finds
2121 none that are appendable, it will search for and recycle (reuse) Purged
2122 Volumes (i.e. volumes with all the Jobs and Files expired and thus
2123 deleted from the Catalog). If the Volume is recycled, all previous data
2124 written to that Volume will be overwritten. If Recycle is set to {\bf
2125 no} you must manually set the recycle flag (update command) for
2126 a Volume to be reused.
2128 Please note that the value defined by this directive in the
2129 bacula-dir.conf file is the default value used when a Volume is created.
2130 Once the volume is created, changing the value in the bacula-dir.conf
2131 file will not change what is stored for the Volume. To change the value
2132 for an existing Volume you must use the {\bf update} command in the
2135 \label{RecycleOldest}
2136 \item [Recycle Oldest Volume = \lt{}yes|no\gt{}]
2137 \index[dir]{Recycle Oldest Volume }
2138 This directive instructs the Director to search for the oldest used
2139 Volume in the Pool when another Volume is requested by the Storage
2140 daemon and none are available. The catalog is then {\bf pruned}
2141 respecting the retention periods of all Files and Jobs written to this
2142 Volume. If all Jobs are pruned (i.e. the volume is Purged), then the
2143 Volume is recycled and will be used as the next Volume to be written.
2144 This directive respects any Job, File, or Volume retention periods that
2145 you may have specified, and as such it is {\bf much} better to use this
2146 directive than the Purge Oldest Volume.
2148 This directive can be useful if you have a fixed number of Volumes in the
2149 Pool and you want to cycle through them and you have specified the correct
2152 However, if you use this directive and have only one
2153 Volume in the Pool, you will immediately recycle your Volume if you fill
2154 it and Bacula needs another one. Thus your backup will be totally invalid.
2155 Please use this directive with care. The default is {\no}.
2157 \label{RecycleCurrent}
2159 \item [Recycle Current Volume = \lt{}yes|no\gt{}]
2160 \index[dir]{Recycle Current Volume }
2161 If Bacula needs a new Volume, this directive instructs Bacula to Prune
2162 the volume respecting the Job and File retention periods. If all Jobs
2163 are pruned (i.e. the volume is Purged), then the Volume is recycled and
2164 will be used as the next Volume to be written. This directive respects
2165 any Job, File, or Volume retention periods that you may have specified,
2166 and thus it is {\bf much} better to use it rather than the Purge Oldest
2169 This directive can be useful if you have: a fixed number of Volumes in
2170 the Pool, you want to cycle through them, and you have specified
2171 retention periods that prune Volumes before you have cycled through the
2174 However, if you use this directive and have only one Volume in the Pool,
2175 you will immediately recycle your Volume if you fill it and Bacula needs
2176 another one. Thus your backup will be totally invalid. Please use this
2177 directive with care. The default is {\no}.
2181 \item [Purge Oldest Volume = \lt{}yes|no\gt{}]
2182 \index[dir]{Purge Oldest Volume }
2183 This directive instructs the Director to search for the oldest used
2184 Volume in the Pool when another Volume is requested by the Storage
2185 daemon and none are available. The catalog is then {\bf purged}
2186 irrespective of retention periods of all Files and Jobs written to this
2187 Volume. The Volume is then recycled and will be used as the next Volume
2188 to be written. This directive overrides any Job, File, or Volume
2189 retention periods that you may have specified.
2191 This directive can be useful if you have a fixed number of Volumes in
2192 the Pool and you want to cycle through them and reusing the oldest one
2193 when all Volumes are full, but you don't want to worry about setting
2194 proper retention periods. However, by using this option you risk losing
2197 Please be aware that {\bf Purge Oldest Volume} disregards all retention
2198 periods. If you have only a single Volume defined and you turn this
2199 variable on, that Volume will always be immediately overwritten when it
2200 fills! So at a minimum, ensure that you have a decent number of Volumes
2201 in your Pool before running any jobs. If you want retention periods to
2202 apply do not use this directive. To specify a retention period, use the
2203 {\bf Volume Retention} directive (see above).
2205 We {\bf highly} recommend against using this directive, because it is
2206 sure that some day, Bacula will recycle a Volume that contains current
2207 data. The default is {\no}.
2209 \item [Cleaning Prefix = \lt{}string\gt{}]
2210 \index[dir]{Cleaning Prefix }
2211 This directive defines a prefix string, which if it matches the
2212 beginning of a Volume name during labeling of a Volume, the Volume will
2213 be defined with the VolStatus set to {\bf Cleaning} and thus Bacula will
2214 never attempt to use this tape. This is primarily for use with
2215 autochangers that accept barcodes where the convention is that barcodes
2216 beginning with {\bf CLN} are treated as cleaning tapes.
2219 \item [Label Format = \lt{}format\gt{}]
2220 \index[dir]{Label Format }
2221 This directive specifies the format of the labels contained in this
2222 pool. The format directive is used as a sort of template to create new
2223 Volume names during automatic Volume labeling.
2225 The {\bf format} should be specified in double quotes, and consists of
2226 letters, numbers and the special characters hyphen ({\bf -}), underscore
2227 ({\bf \_}), colon ({\bf :}), and period ({\bf .}), which are the legal
2228 characters for a Volume name. The {\bf format} should be enclosed in
2231 In addition, the format may contain a number of variable expansion
2232 characters which will be expanded by a complex algorithm allowing you to
2233 create Volume names of many different formats. In all cases, the
2234 expansion process must resolve to the set of characters noted above that
2235 are legal Volume names. Generally, these variable expansion characters
2236 begin with a dollar sign ({\bf \$}) or a left bracket ({\bf [}). If you
2237 specify variable expansion characters, you should always enclose the
2238 format with double quote characters ({\bf "}). For more details on
2239 variable expansion, please see the \ilink{Variable
2240 Expansion}{_ChapterStart50} Chapter of this manual.
2242 If no variable expansion characters are found in the string, the Volume
2243 name will be formed from the {\bf format} string appended with the
2244 number of volumes in the pool plus one, which will be edited as four
2245 digits with leading zeros. For example, with a {\bf Label Format =
2246 "File-"}, the first volumes will be named {\bf File-0001}, {\bf
2249 With the exception of Job specific variables, you can test your {\bf
2250 LabelFormat} by using the \ilink{ var command}{var} the Console Chapter
2253 In almost all cases, you should enclose the format specification (part
2254 after the equal sign) in double quotes. Please note that this directive
2255 is deprecated and is replaced in version 1.37 and greater with a Python
2256 script for creating volume names.
2260 In order for a Pool to be used during a Backup Job, the Pool must have at
2261 least one Volume associated with it. Volumes are created for a Pool using
2262 the {\bf label} or the {\bf add} commands in the {\bf Bacula Console},
2263 program. In addition to adding Volumes to the Pool (i.e. putting the
2264 Volume names in the Catalog database), the physical Volume must be labeled
2265 with a valid Bacula software volume label before {\bf Bacula} will accept
2266 the Volume. This will be automatically done if you use the {\bf label}
2267 command. Bacula can automatically label Volumes if instructed to do so,
2268 but this feature is not yet fully implemented.
2270 The following is an example of a valid Pool resource definition:
2282 \subsubsection*{The Scratch Pool}
2283 \addcontentsline{toc}{subsection}{Scratch Pool}
2284 \index[general]{Scratch Pool}
2285 In general, you can give your Pools any name you wish, but there is one
2286 important restriction: the Pool named {\bf Scratch}, if it exists behaves
2287 like a scratch pool of Volumes in that when Bacula needs a new Volume for
2288 writing and it cannot find one, it will look in the Scratch pool, and if
2289 it finds an available Volume, it will move it out of the Scratch pool into
2290 the Pool currently being used by the job.
2293 \subsection*{The Catalog Resource}
2294 \label{CatalogResource}
2295 \index[general]{Resource!Catalog}
2296 \index[general]{Catalog Resource}
2297 \addcontentsline{toc}{subsection}{Catalog Resource}
2299 The Catalog Resource defines what catalog to use for the current job.
2300 Currently, Bacula can only handle a single database server (SQLite, MySQL,
2301 PostgreSQL) that is defined when configuring {\bf Bacula}. However, there
2302 may be as many Catalogs (databases) defined as you wish. For example, you
2303 may want each Client to have its own Catalog database, or you may want
2304 backup jobs to use one database and verify or restore jobs to use another
2310 \index[dir]{Catalog}
2311 Start of the Catalog resource. At least one Catalog resource must be
2315 \item [Name = \lt{}name\gt{}]
2317 The name of the Catalog. No necessary relation to the database server name.
2318 This name will be specified in the Client resource directive indicating that
2319 all catalog data for that Client is maintained in this Catalog. This
2320 directive is required.
2322 \item [password = \lt{}password\gt{}]
2323 \index[dir]{password }
2324 This specifies the password to use when logging into the database. This
2325 directive is required.
2327 \item [DB Name = \lt{}name\gt{}]
2328 \index[dir]{DB Name }
2329 This specifies the name of the database. If you use multiple catalogs
2330 (databases), you specify which one here. If you are using an external
2331 database server rather than the internal one, you must specify a name that
2332 is known to the server (i.e. you explicitly created the Bacula tables using
2333 this name. This directive is required.
2335 \item [user = \lt{}user\gt{}]
2337 This specifies what user name to use to log into the database. This
2341 \item [DB Socket = \lt{}socket-name\gt{}]
2342 \index[dir]{DB Socket }
2343 This is the name of a socket to use on the local host to connect to the
2344 database. This directive is used only by MySQL and is ignored by SQLite.
2345 Normally, if neither {\bf DB Socket} or {\bf DB Address} are specified, MySQL
2346 will use the default socket.
2348 \item [DB Address = \lt{}address\gt{}]
2349 \index[dir]{DB Address }
2350 This is the host address of the database server. Normally, you would specify
2351 this instead of {\bf DB Socket} if the database server is on another machine.
2352 In that case, you will also specify {\bf DB Port}. This directive is used
2353 only by MySQL and is ignored by SQLite if provided. This directive is
2356 \item [DB Port = \lt{}port\gt{}]
2357 \index[dir]{DB Port }
2358 This defines the port to be used in conjunction with {\bf DB Address} to
2359 access the database if it is on another machine. This directive is used only
2360 by MySQL and is ignored by SQLite if provided. This directive is optional.
2362 %% \item [Multiple Connections = \lt{}yes|no\gt{}]
2363 %% \index[dir]{Multiple Connections }
2364 %% By default, this directive is set to no. In that case, each job that uses
2366 %% same Catalog will use a single connection to the catalog. It will be shared,
2367 %% and Bacula will allow only one Job at a time to communicate. If you set this
2368 %% directive to yes, Bacula will permit multiple connections to the database,
2369 %% and the database must be multi-thread capable. For SQLite and PostgreSQL,
2370 %% this is no problem. For MySQL, you must be *very* careful to have the
2371 %% multi-thread version of the client library loaded on your system. When this
2372 %% directive is set yes, each Job will have a separate connection to the
2373 %% database, and the database will control the interaction between the
2375 %% Jobs. This can significantly speed up the database operations if you are
2376 %% running multiple simultaneous jobs. In addition, for SQLite and PostgreSQL,
2377 %% Bacula will automatically enable transactions. This can significantly speed
2378 %% up insertion of attributes in the database either for a single Job or
2379 %% multiple simultaneous Jobs.
2381 %% This directive has not been tested. Please test carefully before running it
2382 %% in production and report back your results.
2386 The following is an example of a valid Catalog resource definition:
2395 password = "" # no password = no security
2400 or for a Catalog on another machine:
2410 DB Address = remote.acme.com

2426 \subsection*{The Console Resource}
2427 \label{ConsoleResource1}
2428 \index[general]{Console Resource}
2429 \index[general]{Resource!Console}
2430 \addcontentsline{toc}{subsection}{Console Resource}
2432 As of Bacula version 1.33 and higher, there are three different kinds of
2433 consoles, which the administrator or user can use to interact with the
2434 Director. These three kinds of consoles comprise three different security
2438 \item The first console type is an {\bf anonymous} or {\bf default} console,
2439 which has full privileges. There is no console resource necessary for
2440 this type since the password is specified in the Director's resource and
2441 consequently such consoles do not have a name as defined on a {\bf Name
2442 =} directive. This is the kind of console that was initially
2443 implemented in versions prior to 1.33 and remains valid. Typically you
2444 would use it only for administrators.
2446 \item The second type of console, and new to version 1.33 and higher is a
2447 "named" console defined within a Console resource in both the Director's
2448 configuration file and in the Console's configuration file. Both the
2449 names and the passwords in these two entries must match much as is the
2450 case for Client programs.
2452 This second type of console begins with absolutely no privileges except
2453 those explicitly specified in the Director's Console resource. Thus you
2454 can have multiple Consoles with different names and passwords, sort of
2455 like multiple users, each with different privileges. As a default,
2456 these consoles can do absolutely nothing -- no commands whatsoever. You
2457 give them privileges or rather access to commands and resources by
2458 specifying access control lists in the Director's Console resource. The
2459 ACLs are specified by a directive followed by a list of access names.
2460 Examples of this are shown below.
2462 \item The third type of console is similar to the above mentioned one in that
2463 it requires a Console resource definition in both the Director and the
2464 Console. In addition, if the console name, provided on the {\bf Name =}
2465 directive, is the same as a Client name, that console is permitted to
2466 use the {\bf SetIP} command to change the Address directive in the
2467 Director's client resource to the IP address of the Console. This
2468 permits portables or other machines using DHCP (non-fixed IP addresses)
2469 to "notify" the Director of their current IP address.
2472 The Console resource is optional and need not be specified. The following
2473 directives are permitted within the Director's configuration resource:
2477 \item [Name = \lt{}name\gt{}]
2479 The name of the console. This name must match the name specified in the
2480 Console's configuration resource (much as is the case with Client
2483 \item [Password = \lt{}password\gt{}]
2484 \index[dir]{Password }
2485 Specifies the password that must be supplied for a named Bacula Console
2486 to be authorized. The same password must appear in the {\bf Console}
2487 resource of the Console configuration file. For added security, the
2488 password is never actually passed across the network but rather a
2489 challenge response hash code created with the password. This directive
2490 is required. If you have either {\bf /dev/random} {\bf bc} on your
2491 machine, Bacula will generate a random password during the configuration
2492 process, otherwise it will be left blank.
2494 \item [JobACL = \lt{}name-list\gt{}]
2495 \index[dir]{JobACL }
2496 This directive is used to specify a list of Job resource names that can
2497 be accessed by the console. Without this directive, the console cannot
2498 access any of the Director's Job resources. Multiple Job resource names
2499 may be specified by separating them with commas, and/or by specifying
2500 multiple JobACL directives. For example, the directive may be specified
2505 JobACL = kernsave, "Backup client 1", "Backup client 2"
2506 JobACL = "RestoreFiles"
2511 With the above specification, the console can access the Director's resources
2512 for the four jobs named on the JobACL directives, but for no others.
2514 \item [ClientACL = \lt{}name-list\gt{}]
2515 \index[dir]{ClientACL }
2516 This directive is used to specify a list of Client resource names that can
2518 accessed by the console.
2520 \item [StorageACL = \lt{}name-list\gt{}]
2521 \index[dir]{StorageACL }
2522 This directive is used to specify a list of Storage resource names that can
2523 be accessed by the console.
2525 \item [ScheduleACL = \lt{}name-list\gt{}]
2526 \index[dir]{ScheduleACL }
2527 This directive is used to specify a list of Schedule resource names that can
2528 be accessed by the console.
2530 \item [PoolACL = \lt{}name-list\gt{}]
2531 \index[dir]{PoolACL }
2532 This directive is used to specify a list of Pool resource names that can be
2533 accessed by the console.
2535 \item [FileSetACL = \lt{}name-list\gt{}]
2536 \index[dir]{FileSetACL }
2537 This directive is used to specify a list of FileSet resource names that can
2538 be accessed by the console.
2540 \item [CatalogACL = \lt{}name-list\gt{}]
2541 \index[dir]{CatalogACL }
2542 This directive is used to specify a list of Catalog resource names that can
2543 be accessed by the console.
2545 \item [CommandACL = \lt{}name-list\gt{}]
2546 \index[dir]{CommandACL }
2547 This directive is used to specify a list of of console commands that can be
2548 executed by the console.
2551 Aside from Director resource names and console command names, the special
2552 keyword {\bf *all*} can be specified in any of the above access control lists.
2553 When this keyword is present, any resource or command name (which ever is
2554 appropriate) will be accepted. For an example configuration file, please see
2556 \ilink{Console Configuration}{_ChapterStart36} chapter of this

2560 \label{CounterResource}

2563 \addcontentsline{toc}{subsection}{Counter Resource}
2565 The Counter Resource defines a counter variable that can be accessed by
2566 variable expansion used for creating Volume labels with the {\bf LabelFormat}
2568 \ilink{LabelFormat}{Label} directive in this chapter for more
2574 \index[dir]{Counter}
2575 Start of the Counter resource. Counter directives are optional.
2577 \item [Name = \lt{}name\gt{}]
2579 The name of the Counter. This is the name you will use in the variable
2580 expansion to reference the counter value.
2582 \item [Minimum = \lt{}integer\gt{}]
2583 \index[dir]{Minimum }
2584 This specifies the minimum value that the counter can have. It also becomes
2585 the default. If not supplied, zero is assumed.
2587 \item [Maximum = \lt{}integer\gt{}]
2588 \index[dir]{Maximum }
2589 This is the maximum value value that the counter can have. If not specified
2590 or set to zero, the counter can have a maximum value of 2,147,483,648 (2 to
2591 the 31 power). When the counter is incremented past this value, it is reset
2594 \item [*WrapCounter = \lt{}counter-name\gt{}]
2595 \index[dir]{*WrapCounter }
2596 If this value is specified, when the counter is incremented past the
2598 and thus reset to the minimum, the counter specified on the {\bf WrapCounter}
2599 is incremented. (This is not currently implemented).
2601 \item [Catalog = \lt{}catalog-name\gt{}]
2602 \index[dir]{Catalog }
2603 If this directive is specified, the counter and its values will be saved in
2604 the specified catalog. If this directive is not present, the counter will be
2605 redefined each time that Bacula is started.
