9 This document describes the utility programs written to aid Bacula users and
10 developers in dealing with Volumes external to Bacula.
12 \section{Specifying the Configuration File}
13 \index[general]{Specifying the Configuration File}
15 Starting with version 1.27, each of the following programs requires a valid
16 Storage daemon configuration file (actually, the only part of the
17 configuration file that these programs need is the {\bf Device} resource
18 definitions). This permits the programs to find the configuration parameters
19 for your archive device (generally a tape drive). By default, they read {\bf
20 bacula-sd.conf} in the current directory, but you may specify a different
21 configuration file using the {\bf -c} option.
24 \section{Specifying a Device Name For a Tape}
25 \index[general]{Tape!Specifying a Device Name For a}
26 \index[general]{Specifying a Device Name For a Tape}
28 Each of these programs require a {\bf device-name} where the Volume can be
29 found. In the case of a tape, this is the physical device name such as {\bf
30 /dev/nst0} or {\bf /dev/rmt/0ubn} depending on your system. For the program to
31 work, it must find the identical name in the Device resource of the
32 configuration file. See below for specifying Volume names.
34 Please note that if you have Bacula running and you ant to use
35 one of these programs, you will either need to stop the Storage daemon, or
36 {\bf unmount} any tape drive you want to use, otherwise the drive
37 will {\bf busy} because Bacula is using it.
40 \section{Specifying a Device Name For a File}
41 \index[general]{File!Specifying a Device Name For a}
42 \index[general]{Specifying a Device Name For a File}
44 If you are attempting to read or write an archive file rather than a tape, the
45 {\bf device-name} should be the full path to the archive location including
46 the filename. The filename (last part of the specification) will be stripped
47 and used as the Volume name, and the path (first part before the filename)
48 must have the same entry in the configuration file. So, the path is equivalent
49 to the archive device name, and the filename is equivalent to the volume name.
52 \section{Specifying Volumes}
53 \index[general]{Volumes!Specifying}
54 \index[general]{Specifying Volumes}
56 In general, you must specify the Volume name to each of the programs below
57 (with the exception of {\bf btape}). The best method to do so is to specify a
58 {\bf bootstrap} file on the command line with the {\bf -b} option. As part of
59 the bootstrap file, you will then specify the Volume name or Volume names if
60 more than one volume is needed. For example, suppose you want to read tapes
61 {\bf tape1} and {\bf tape2}. First construct a {\bf bootstrap} file named say,
62 {\bf list.bsr} which contains:
70 where each Volume is separated by a vertical bar. Then simply use:
74 ./bls -b list.bsr /dev/nst0
78 In the case of Bacula Volumes that are on files, you may simply append volumes
83 ./bls /tmp/test1\|test2
87 where the backslash (\textbackslash{}) was necessary as a shell escape to
88 permit entering the vertical bar (|).
90 And finally, if you feel that specifying a Volume name is a bit complicated
91 with a bootstrap file, you can use the {\bf -V} option (on all programs except
92 {\bf bcopy}) to specify one or more Volume names separated by the vertical bar
97 ./bls -V Vol001 /dev/nst0
101 You may also specify an asterisk (*) to indicate that the program should
102 accept any volume. For example:
113 \index[general]{program!bls}
115 {\bf bls} can be used to do an {\bf ls} type listing of a {\bf Bacula} tape or
120 Usage: bls [options] <device-name>
121 -b <file> specify a bootstrap file
122 -c <file> specify a config file
123 -d <level> specify debug level
124 -e <file> exclude list
125 -i <file> include list
128 (no j or k option) list saved files
130 -p proceed inspite of errors
132 -V specify Volume names (separated by |)
133 -? print this message
137 For example, to list the contents of a tape:
141 ./bls -V Volume-name /dev/nst0
145 Or to list the contents of a file:
149 ./bls /tmp/Volume-name
151 ./bls -V Volume-name /tmp
155 Note that, in the case of a file, the Volume name becomes the filename, so in
156 the above example, you will replace the {\bf xxx} with the name of the volume
159 Normally if no options are specified, {\bf bls} will produce the equivalent
160 output to the {\bf ls -l} command for each file on the tape. Using other
161 options listed above, it is possible to display only the Job records, only the
162 tape blocks, etc. For example:
168 bls: butil.c:148 Using device: /tmp

188 \index[general]{Listing Jobs with bls}
189 \index[general]{bls!Listing Jobs}
191 If you are listing a Volume to determine what Jobs to restore, normally the
192 {\bf -j} option provides you with most of what you will need as long as you
193 don't have multiple clients. For example,
197 ./bls -j -V Test1 -c stored.conf DDS-4
198 bls: butil.c:258 Using device: "DDS-4" for reading.
199 11-Jul 11:54 bls: Ready to read from volume "Test1" on device "DDS-4" (/dev/nst0).

218 shows a full save followed by two incremental saves.
220 Adding the {\bf -v} option will display virtually all information that is
221 available for each record:
223 \subsection{Listing Blocks}
224 \index[general]{Listing Blocks with bls}
225 \index[general]{bls!Listing Blocks}
227 Normally, except for debugging purposes, you will not need to list Bacula
228 blocks (the "primitive" unit of Bacula data on the Volume). However, you can
233 ./bls -k /tmp/File002
234 bls: butil.c:148 Using device: /tmp
240 bls: Got EOF on device /tmp
241 End of File on device
245 By adding the {\bf -v} option, you can get more information, which can be
246 useful in knowing what sessions were written to the volume:
250 ./bls -k -v /tmp/File002
252 Id : Bacula 0.9 mortal
257 LabelType : VOL_LABEL
263 Date label written: 2002-10-19 at 21:16
264 Block: 1 blen=64512 First rec FI=VOL_LABEL SessId=1 SessTim=1035062102 Strm=0 rlen=147
265 Block: 2 blen=64512 First rec FI=6 SessId=1 SessTim=1035062102 Strm=DATA rlen=4087
266 Block: 3 blen=64512 First rec FI=12 SessId=1 SessTim=1035062102 Strm=DATA rlen=5902

271 bls: Got EOF on device /tmp
272 End of File on device
276 Armed with the SessionId and the SessionTime, you can extract just about
279 If you want to know even more, add a second {\bf -v} to the command line to
280 get a dump of every record in every block.

314 \index[general]{Bextract}
315 \index[general]{program!bextract}
317 If you find yourself using {\bf bextract}, you probably have done
318 something wrong. For example, if you are trying to recover a file
319 but are having problems, please see the \ilink {Restoring When Things Go
320 Wrong}{database_restore} section of the Restore chapter of this manual.
322 Normally, you will restore files by running a {\bf Restore} Job from the {\bf
323 Console} program. However, {\bf bextract} can be used to extract a single file
324 or a list of files from a Bacula tape or file. In fact, {\bf bextract} can be
325 a useful tool to restore files to an empty system assuming you are able to
326 boot, you have statically linked {\bf bextract} and you have an appropriate
327 {\bf bootstrap} file.
329 Please note that some of the current limitations of bextract are:
332 \item It cannot restore access control lists (ACL) that have been
333 backed up along with the file data.
334 \item It cannot restore encrypted files.
335 \item The command line length is relatively limited,
336 which means that you cannot enter a huge number of volumes. If you need to
337 enter more volumes than the command line supports, please use a bootstrap
347 Usage: bextract [-d debug_level] <device-name> <directory-to-store-files>
348 -b <file> specify a bootstrap file
349 -dnn set debug level to nn
350 -e <file> exclude list
351 -i <file> include list
352 -p proceed inspite of I/O errors
353 -V specify Volume names (separated by |)
354 -? print this message
358 where {\bf device-name} is the Archive Device (raw device name or full
359 filename) of the device to be read, and {\bf directory-to-store-files} is a
360 path prefix to prepend to all the files restored.
362 NOTE: On Windows systems, if you specify a prefix of say d:/tmp, any file that
363 would have been restored to {\bf c:/My Documents} will be restored to {\bf
364 d:/tmp/My Documents}. That is, the original drive specification will be
365 stripped. If no prefix is specified, the file will be restored to the original
368 \subsection{Extracting with Include or Exclude Lists}
369 \index[general]{Lists!Extracting with Include or Exclude}
370 \index[general]{Extracting with Include or Exclude Lists}
372 Using the {\bf -e} option, you can specify a file containing a list of files
373 to be excluded. Wildcards can be used in the exclusion list. This option will
374 normally be used in conjunction with the {\bf -i} option (see below). Both the
375 {\bf -e} and the {\bf -i} options may be specified at the same time as the
376 {\bf -b} option. The bootstrap filters will be applied first, then the include
377 list, then the exclude list.
379 Likewise, and probably more importantly, with the {\bf -i} option, you can
380 specify a file that contains a list (one file per line) of files and
381 directories to include to be restored. The list must contain the full filename
382 with the path. If you specify a path name only, all files and subdirectories
383 of that path will be restored. If you specify a line containing only the
384 filename (e.g. {\bf my-file.txt}) it probably will not be extracted because
385 you have not specified the full path.
387 For example, if the file {\bf include-list} contains:
400 ./bextract -i include-list -V Volume /dev/nst0 /tmp
404 will restore from the Bacula archive {\bf /dev/nst0} all files and directories
405 in the backup from {\bf /home/kern/bacula} and from {\bf /usr/local/bin}. The
406 restored files will be placed in a file of the original name under the
407 directory {\bf /tmp} (i.e. /tmp/home/kern/bacula/... and
408 /tmp/usr/local/bin/...).
410 \subsection{Extracting With a Bootstrap File}
411 \index[general]{File!Extracting With a Bootstrap}
412 \index[general]{Extracting With a Bootstrap File}
414 The {\bf -b} option is used to specify a {\bf bootstrap} file containing the
415 information needed to restore precisely the files you want. Specifying a {\bf
416 bootstrap} file is optional but recommended because it gives you the most
417 control over which files will be restored. For more details on the {\bf
418 bootstrap} file, please see
419 \ilink{Restoring Files with the Bootstrap File}{BootstrapChapter}
420 chapter of this document. Note, you may also use a bootstrap file produced by
421 the {\bf restore} command. For example:
425 ./bextract -b bootstrap-file /dev/nst0 /tmp
429 The bootstrap file allows detailed specification of what files you want
430 restored (extracted). You may specify a bootstrap file and include and/or
431 exclude files at the same time. The bootstrap conditions will first be
432 applied, and then each file record seen will be compared to the include and
435 \subsection{Extracting From Multiple Volumes}
436 \index[general]{Volumes!Extracting From Multiple}
437 \index[general]{Extracting From Multiple Volumes}
439 If you wish to extract files that span several Volumes, you can specify the
440 Volume names in the bootstrap file or you may specify the Volume names on the
441 command line by separating them with a vertical bar. See the section above
442 under the {\bf bls} program entitled {\bf Listing Multiple Volumes} for more
443 information. The same techniques apply equally well to the {\bf bextract}
444 program or read the \ilink{Bootstrap}{BootstrapChapter}
445 chapter of this document.
449 \index[general]{bscan}
450 \index[general]{program!bscan}
452 If you find yourself using this program, you have probably done something
453 wrong. For example, the best way to recover a lost or damaged Bacula
454 database is to reload the database by using the bootstrap file that
455 was written when you saved it (default bacula-dir.conf file).
457 The {\bf bscan} program can be used to re-create a database (catalog)
458 records from the backup information written to one or more Volumes. This
459 is normally needed only if one or more Volumes have been pruned or purged
460 from your catalog so that the records on the Volume are no longer in the
461 catalog, or for Volumes that you have archived. Note, if you scan in
462 Volumes that were previously purged, you will be able to do restores from
463 those Volumes. However, unless you modify the Job and File retention times
464 for the Jobs that were added by scanning, the next time you run any Job
465 with the same name, the records will be pruned again. Since it takes a
466 long time to scan Volumes this can be very frustrating.
468 With some care, {\bf bscan} can also be used to synchronize your existing
469 catalog with a Volume. Although we have never seen a case of bscan
470 damaging a catalog, since bscan modifies your catalog, we recommend that
471 you do a simple ASCII backup of your database before running {\bf bscan}
472 just to be sure. See \ilink{Compacting Your Database}{CompactingMySQL} for
473 the details of making a copy of your database.
475 {\bf bscan} can also be useful in a disaster recovery situation, after the
476 loss of a hard disk, if you do not have a valid {\bf bootstrap} file for
477 reloading your system, or if a Volume has been recycled but not overwritten,
478 you can use {\bf bscan} to re-create your database, which can then be used to
479 {\bf restore} your system or a file to its previous state.
486 Usage: bscan [options] <bacula-archive>
487 -b bootstrap specify a bootstrap file
488 -c <file> specify configuration file
489 -d <nn> set debug level to nn
490 -m update media info in database
491 -n <name> specify the database name (default bacula)
492 -u <user> specify database user name (default bacula)
493 -P <password> specify database password (default none)
494 -h <host> specify database host (default NULL)
495 -p proceed inspite of I/O errors
497 -s synchronize or store in database
499 -V <Volumes> specify Volume names (separated by |)
500 -w <dir> specify working directory (default from conf file)
501 -? print this message
505 If you are using MySQL or PostgreSQL, there is no need to supply a working
506 directory since in that case, bscan knows where the databases are. However, if
507 you have provided security on your database, you may need to supply either the
508 database name ({\bf -b} option), the user name ({\bf -u} option), and/or the
509 password ({\bf -p}) options.
511 NOTE: before {\bf bscan} can work, it needs at least a bare bones valid
512 database. If your database exists but some records are missing because
513 they were pruned, then you are all set. If your database was lost or
514 destroyed, then you must first ensure that you have the SQL program running
515 (MySQL or PostgreSQL), then you must create the Bacula database (normally
516 named bacula), and you must create the Bacula tables using the scripts in
517 the {\bf cats} directory. This is explained in the
518 \ilink{Installation}{CreateDatabase} chapter of the manual. Finally, before
519 scanning into an empty database, you must start and stop the Director with
520 the appropriate bacula-dir.conf file so that it can create the Client and
521 Storage records which are not stored on the Volumes. Without these
522 records, scanning is unable to connect the Job records to the proper
525 Forgetting for the moment the extra complications of a full rebuild of
526 your catalog, let's suppose that you did a backup to Volumes "Vol001"
527 and "Vol002", then sometime later all records of one or both those
528 Volumes were pruned or purged from the
529 database. By using {\bf bscan} you can recreate the catalog entries for
530 those Volumes and then use the {\bf restore} command in the Console to restore
531 whatever you want. A command something like:
535 bscan -c bacula-sd.conf -v -V Vol001\|Vol002 /dev/nst0
539 will give you an idea of what is going to happen without changing
540 your catalog. Of course, you may need to change the path to the Storage
541 daemon's conf file, the Volume name, and your tape (or disk) device name. This
542 command must read the entire tape, so if it has a lot of data, it may take a
543 long time, and thus you might want to immediately use the command listed
544 below. Note, if you are writing to a disk file, replace the device name with
545 the path to the directory that contains the Volumes. This must correspond to
546 the Archive Device in the conf file.
548 Then to actually write or store the records in the catalog, add the {\bf -s}
553 bscan -s -m -c bacula-sd.conf -v -V Vol001\|Vol002 /dev/nst0
557 When writing to the database, if bscan finds existing records, it will
558 generally either update them if something is wrong or leave them alone. Thus
559 if the Volumes you are scanning are all or partially in the catalog already, no
560 harm will be done to that existing data. Any missing data will simply be
563 If you have multiple tapes, you should scan them with:
567 bscan -s -m -c bacula-sd.conf -v -V Vol001\|Vol002\|Vol003 /dev/nst0
571 Since there is a limit on the command line length (511 bytes) accepted
572 by {\bf bscan}, if you have too many Volumes, you will need to manually
573 create a bootstrap file. See the \ilink{Bootstrap}{BootstrapChapter}
574 chapter of this manual for more details, in particular the section
575 entitled \ilink{Bootstrap for bscan}{bscanBootstrap}.
577 You should, always try to specify the tapes in the order they are written.
578 However, bscan can handle scanning tapes that are not sequential. Any
579 incomplete records at the end of the tape will simply be ignored in that
580 case. If you are simply repairing an existing catalog, this may be OK, but
581 if you are creating a new catalog from scratch, it will leave your database
582 in an incorrect state. If you do not specify all necessary Volumes on a
583 single bscan command, bscan will not be able to correctly restore the
584 records that span two volumes. In other words, it is much better to
585 specify two or three volumes on a single bscan command rather than run
586 bscan two or three times, each with a single volume.
589 Note, the restoration process using bscan is not identical to the original
590 creation of the catalog data. This is because certain data such as Client
591 records and other non-essential data such
592 as volume reads, volume mounts, etc is not stored on the Volume, and thus is
593 not restored by bscan. The results of bscanning are, however, perfectly valid,
594 and will permit restoration of any or all the files in the catalog using the
595 normal Bacula console commands. If you are starting with an empty catalog
596 and expecting bscan to reconstruct it, you may be a bit disappointed, but
597 at a minimum, you must ensure that your bacula-dir.conf file is the same
598 as what it previously was -- that is, it must contain all the appropriate
599 Client resources so that they will be recreated in your new database {\bf
600 before} running bscan. Normally when the Director starts, it will recreate
601 any missing Client records in the catalog. Another problem you will have
602 is that even if the Volumes (Media records) are recreated in the database,
603 they will not have their autochanger status and slots properly set. As a
604 result, you will need to repair that by using the {\bf update slots}
605 command. There may be other considerations as well. Rather than
606 bscanning, you should always attempt to recover you previous catalog

612 \index[general]{Using bscan to Compare a Volume to an existing Catalog}
614 If you wish to compare the contents of a Volume to an existing catalog without
615 changing the catalog, you can safely do so if and only if you do {\bf not}
616 specify either the {\bf -m} or the {\bf -s} options. However, at this time
617 (Bacula version 1.26), the comparison routines are not as good or as thorough
618 as they should be, so we don't particularly recommend this mode other than for

623 \index[general]{Using bscan to Recreate a Catalog from a Volume}
625 This is the mode for which {\bf bscan} is most useful. You can either {\bf
626 bscan} into a freshly created catalog, or directly into your existing catalog
627 (after having made an ASCII copy as described above). Normally, you should
628 start with a freshly created catalog that contains no data.
630 Starting with a single Volume named {\bf TestVolume1}, you run a command such
635 ./bscan -V TestVolume1 -v -s -m -c bacula-sd.conf /dev/nst0
639 If there is more than one volume, simply append it to the first one separating
640 it with a vertical bar. You may need to precede the vertical bar with a
641 forward slash escape the shell -- e.g. {\bf
642 TestVolume1\textbackslash{}|TestVolume2}. The {\bf -v} option was added for
643 verbose output (this can be omitted if desired). The {\bf -s} option that
644 tells {\bf bscan} to store information in the database. The physical device
645 name {\bf /dev/nst0} is specified after all the options.
647 {\bf} For example, after having done a full backup of a directory, then two
648 incrementals, I reinitialized the SQLite database as described above, and
649 using the bootstrap.bsr file noted above, I entered the following command:
653 ./bscan -b bootstrap.bsr -v -s -c bacula-sd.conf /dev/nst0
657 which produced the following output:
661 bscan: bscan.c:182 Using Database: bacula, User: bacula
662 bscan: bscan.c:673 Created Pool record for Pool: Default
663 bscan: bscan.c:271 Pool type "Backup" is OK.

686 bscan: bscan.c:428 End of Volume. VolFiles=3 VolBlocks=57 VolBytes=10,027,437
690 The key points to note are that {\bf bscan} prints a line when each major
691 record is created. Due to the volume of output, it does not print a line for
692 each file record unless you supply the {\bf -v} option twice or more on the
695 In the case of a Job record, the new JobId will not normally be the same as
696 the original Jobid. For example, for the first JobId above, the new JobId is
697 1, but the original JobId is 2. This is nothing to be concerned about as it is
698 the normal nature of databases. {\bf bscan} will keep everything straight.
700 Although {\bf bscan} claims that it created a Client record for Client: Rufus
701 three times, it was actually only created the first time. This is normal.
703 You will also notice that it read an end of file after each Job (Got EOF on
704 device ...). Finally the last line gives the total statistics for the bscan.
706 If you had added a second {\bf -v} option to the command line, Bacula would
707 have been even more verbose, dumping virtually all the details of each Job
708 record it encountered.
710 Now if you start Bacula and enter a {\bf list jobs} command to the console
711 program, you will get:
715 +-------+----------+------------------+------+-----+----------+----------+---------+
716 | JobId | Name | StartTime | Type | Lvl | JobFiles | JobBytes | JobStat |
717 +-------+----------+------------------+------+-----+----------+----------+---------+
718 | 1 | kernsave | 2002-10-07 14:59 | B | F | 84 | 4180207 | T |
719 | 2 | kernsave | 2002-10-07 15:00 | B | I | 15 | 2170314 | T |
720 | 3 | kernsave | 2002-10-07 15:01 | B | I | 33 | 3662184 | T |
721 +-------+----------+------------------+------+-----+----------+----------+---------+
725 which corresponds virtually identically with what the database contained
726 before it was re-initialized and restored with bscan. All the Jobs and Files
727 found on the tape are restored including most of the Media record. The Volume
728 (Media) records restored will be marked as {\bf Full} so that they cannot be
729 rewritten without operator intervention.
731 It should be noted that {\bf bscan} cannot restore a database to the exact
732 condition it was in previously because a lot of the less important information
733 contained in the database is not saved to the tape. Nevertheless, the
734 reconstruction is sufficiently complete, that you can run {\bf restore}
735 against it and get valid results.
737 An interesting aspect of restoring a catalog backup using {\bf bscan} is
738 that the backup was made while Bacula was running and writing to a tape. At
739 the point the backup of the catalog is made, the tape Bacula is writing to
740 will have say 10 files on it, but after the catalog backup is made, there
741 will be 11 files on the tape Bacula is writing. This there is a difference
742 between what is contained in the backed up catalog and what is actually on
743 the tape. If after restoring a catalog, you attempt to write on the same
744 tape that was used to backup the catalog, Bacula will detect the difference
745 in the number of files registered in the catalog compared to what is on the
746 tape, and will mark the tape in error.
748 There are two solutions to this problem. The first is possibly the simplest
749 and is to mark the volume as Used before doing any backups. The second is
750 to manually correct the number of files listed in the Media record of the
751 catalog. This procedure is documented elsewhere in the manual and involves
752 using the {\bf update volume} command in {\bf bconsole}.
754 \subsection{Using bscan to Correct the Volume File Count}
755 \index[general]{Using bscan to Correct the Volume File Count}
756 \index[general]{Count!Using bscan to Correct the Volume File Count}
758 If the Storage daemon crashes during a backup Job, the catalog will not be
759 properly updated for the Volume being used at the time of the crash. This
760 means that the Storage daemon will have written say 20 files on the tape, but
761 the catalog record for the Volume indicates only 19 files.
763 Bacula refuses to write on a tape that contains a different number of files
764 from what is in the catalog. To correct this situation, you may run a {\bf
765 bscan} with the {\bf -m} option (but {\bf without} the {\bf -s} option) to
766 update only the final Media record for the Volumes read.
768 \subsection{After bscan}
769 \index[general]{After bscan}
770 \index[general]{Bscan!After}
772 If you use {\bf bscan} to enter the contents of the Volume into an existing
773 catalog, you should be aware that the records you entered may be immediately
774 pruned during the next job, particularly if the Volume is very old or had been
775 previously purged. To avoid this, after running {\bf bscan}, you can manually
776 set the volume status (VolStatus) to {\bf Read-Only} by using the {\bf update}
777 command in the catalog. This will allow you to restore from the volume without
778 having it immediately purged. When you have restored and backed up the data,
779 you can reset the VolStatus to {\bf Used} and the Volume will be purged from
784 \index[general]{Bcopy}
785 \index[general]{program!bcopy}
787 The {\bf bcopy} program can be used to copy one {\bf Bacula} archive file to
788 another. For example, you may copy a tape to a file, a file to a tape, a file
789 to a file, or a tape to a tape. For tape to tape, you will need two tape
790 drives. (a later version is planned that will buffer it to disk). In the
791 process of making the copy, no record of the information written to the new
792 Volume is stored in the catalog. This means that the new Volume, though it
793 contains valid backup data, cannot be accessed directly from existing catalog
794 entries. If you wish to be able to use the Volume with the Console restore
795 command, for example, you must first bscan the new Volume into the catalog.

832 This program permits a number of elementary tape operations via a tty command
833 interface. It works only with tapes and not with other kinds of Bacula
834 storage media (DVD, File, ...). The {\bf test} command, described below,
835 can be very useful for testing older tape drive compatibility problems.
836 Aside from initial testing of tape drive compatibility with {\bf Bacula},
837 {\bf btape} will be mostly used by developers writing new tape drivers.
839 {\bf btape} can be dangerous to use with existing {\bf Bacula} tapes because
840 it will relabel a tape or write on the tape if so requested regardless that
841 the tape may contain valuable data, so please be careful and use it only on
844 To work properly, {\bf btape} needs to read the Storage daemon's configuration

926 \item test -- test writing records and EOF marks and reading them back.
927 \item fill -- completely fill a volume with records, then write a few records
928 on a second volume, and finally, both volumes will be read back.
929 This command writes blocks containing random data, so your drive will
930 not be able to compress the data, and thus it is a good test of
931 the real physical capacity of your tapes.
932 \item readlabel -- read and dump the label on a Bacula tape.
933 \item cap -- list the device capabilities as defined in the configuration
934 file and as perceived by the Storage daemon.
937 The {\bf readlabel} command can be used to display the details of a Bacula
938 tape label. This can be useful if the physical tape label was lost or damaged.
941 In the event that you want to relabel a {\bf Bacula}, you can simply use the
942 {\bf label} command which will write over any existing label. However, please
943 note for labeling tapes, we recommend that you use the {\bf label} command in
944 the {\bf Console} program since it will never overwrite a valid Bacula tape.

996 \index[general]{Other Programs}
998 The following programs are general utility programs and in general do not need
999 a configuration file nor a device name.
1003 \index[general]{Bsmtp}
1004 \index[general]{program!bsmtp}
1006 {\bf bsmtp} is a simple mail transport program that permits more flexibility
1007 than the standard mail programs typically found on Unix systems. It can even
1008 be used on Windows machines.
1014 Usage: bsmtp [-f from] [-h mailhost] [-s subject] [-c copy] [recipient ...]
1015 -c set the Cc: field
1016 -dnn set debug level to nn
1017 -f set the From: field
1018 -h use mailhost:port as the bsmtp server
1019 -l limit the lines accepted to nn
1020 -s set the Subject: field
1021 -? print this message.
1025 If the {\bf -f} option is not specified, {\bf bsmtp} will use your userid. If
1026 the option {\bf -h} is not specified {\bf bsmtp} will use the value in the environment
1027 variable {\bf bsmtpSERVER} or if there is none {\bf localhost}. By default
1030 If a line count limit is set with the {\bf -l} option, {\bf bsmtp} will
1031 not send an email with a body text exceeding that number of lines. This
1032 is especially useful for large restore job reports where the list of
1033 files restored might produce very long mails your mail-server would
1034 refuse or crash. However, be aware that you will probably suppress the
1035 job report and any error messages unless you check the log file written
1036 by the Director (see the messages resource in this manual for details).
1039 {\bf recipients} is a space separated list of email recipients.
1041 The body of the email message is read from standard input.
1043 An example of the use of {\bf bsmtp} would be to put the following statement
1044 in the {\bf Messages} resource of your {\bf bacula-dir.conf} file. Note, these
1045 commands should appear on a single line each.
1049 mailcommand = "/home/bacula/bin/bsmtp -h mail.domain.com -f \"\(Bacula\) %r\"
1050 -s \"Bacula: %t %e of %c %l\" %r"
1051 operatorcommand = "/home/bacula/bin/bsmtp -h mail.domain.com -f \"\(Bacula\) %r\"
1052 -s \"Bacula: Intervention needed for %j\" %r"
1056 Where you replace {\bf /home/bacula/bin} with the path to your {\bf Bacula}
1057 binary directory, and you replace {\bf mail.domain.com} with the fully
1058 qualified name of your bsmtp (email) server, which normally listens on port
1059 25. For more details on the substitution characters (e.g. \%r) used in the
1060 above line, please see the documentation of the
1061 \ilink{ MailCommand in the Messages Resource}{mailcommand}
1062 chapter of this manual.
1064 It is HIGHLY recommended that you test one or two cases by hand to make sure
1065 that the {\bf mailhost} that you specified is correct and that it will accept
1066 your email requests. Since {\bf bsmtp} always uses a TCP connection rather
1067 than writing in the spool file, you may find that your {\bf from} address is
1068 being rejected because it does not contain a valid domain, or because your
1069 message is caught in your spam filtering rules. Generally, you should specify
1070 a fully qualified domain name in the {\bf from} field, and depending on
1071 whether your bsmtp gateway is Exim or Sendmail, you may need to modify the
1072 syntax of the from part of the message. Please test.
1074 When running {\bf bsmtp} by hand, you will need to terminate the message by
1075 entering a ctl-d in column 1 of the last line.
1076 % TODO: is "column" the correct terminology for this?
1078 If you are getting incorrect dates (e.g. 1970) and you are
1079 running with a non-English language setting, you might try adding
1080 a LANG=''en\_US'' immediately before the bsmtp call.
1082 In general, {\bf bsmtp} attempts to cleanup email addresses that you
1083 specify in the from, copy, mailhost, and recipient fields, by adding
1084 the necessary \lt{} and \gt{} characters around the address part. However,
1085 if you include a {\bf display-name} (see RFC 5332), some SMTP servers
1086 such as Exchange may not accept the message if the {\bf display-name} is
1087 also included in \lt{} and \gt{}. As mentioned above, you must test, and
1088 if you run into this situation, you may manually add the \lt{} and \gt{}
1089 to the Bacula {\bf mailcommand} or {\bf operatorcommand} and when
1090 {\bf bsmtp} is formatting an address if it already contains a \lt{} or
1091 \gt{} character, it will leave the address unchanged.
1095 \index[general]{Dbcheck}
1096 \index[general]{program!dbcheck}
1097 {\bf dbcheck} is a simple program that will search for logical
1098 inconsistencies in the Bacula tables in your database, and optionally fix them.
1099 It is a database maintenance routine, in the sense that it can
1100 detect and remove unused rows, but it is not a database repair
1101 routine. To repair a database, see the tools furnished by the
1102 database vendor. Normally dbcheck should never need to be run,
1103 but if Bacula has crashed or you have a lot of Clients, Pools, or

1106 The {\bf dbcheck} program can be found in
1107 the {\bf \lt{}bacula-source\gt{}/src/tools} directory of the source
1108 distribution. Though it is built with the make process, it is not normally
1115 Usage: dbcheck [-c config ] [-B] [-C catalog name] [-d debug_level]
1116 <working-directory> <bacula-database> <user> <password> [<dbhost>] [<dbport>]
1118 -C catalog name in the director conf file
1119 -c Director conf filename
1120 -B print catalog configuration and exit
1121 -d <nn> set debug level to <nn>
1122 -dt print timestamp in debug output
1123 -f fix inconsistencies
1125 -? print this message
1129 If the \textbf{-B} option is specified, dbcheck will print out catalog
1130 information in a simple text based format. This is useful to backup it in a
1146 If the {\bf -c} option is given with the Director's conf file, there is no
1147 need to enter any of the command line arguments, in particular the working
1148 directory as dbcheck will read them from the file.
1150 If the {\bf -f} option is specified, {\bf dbcheck} will repair ({\bf fix}) the
1151 inconsistencies it finds. Otherwise, it will report only.
1153 If the {\bf -b} option is specified, {\bf dbcheck} will run in batch mode, and
1154 it will proceed to examine and fix (if -f is set) all programmed inconsistency
1155 checks. If the {\bf -b} option is not specified, {\bf dbcheck} will enter
1156 interactive mode and prompt with the following:
1160 Hello, this is the database check/correct program.
1161 Please select the function you want to perform.
1162 1) Toggle modify database flag
1163 2) Toggle verbose flag
1164 3) Repair bad Filename records
1165 4) Repair bad Path records
1166 5) Eliminate duplicate Filename records
1167 6) Eliminate duplicate Path records
1168 7) Eliminate orphaned Jobmedia records
1169 8) Eliminate orphaned File records
1170 9) Eliminate orphaned Path records
1171 10) Eliminate orphaned Filename records
1172 11) Eliminate orphaned FileSet records
1173 12) Eliminate orphaned Client records
1174 13) Eliminate orphaned Job records
1175 14) Eliminate all Admin records
1176 15) Eliminate all Restore records
1179 Select function number:
1183 By entering 1 or 2, you can toggle the modify database flag (-f option) and
1184 the verbose flag (-v). It can be helpful and reassuring to turn off the modify
1185 database flag, then select one or more of the consistency checks (items 3
1186 through 9) to see what will be done, then toggle the modify flag on and re-run
1189 The inconsistencies examined are the following:
1192 \item Duplicate filename records. This can happen if you accidentally run two
1193 copies of Bacula at the same time, and they are both adding filenames
1194 simultaneously. It is a rare occurrence, but will create an inconsistent
1195 database. If this is the case, you will receive error messages during Jobs
1196 warning of duplicate database records. If you are not getting these error
1197 messages, there is no reason to run this check.
1198 \item Repair bad Filename records. This checks and corrects filenames that
1199 have a trailing slash. They should not.
1200 \item Repair bad Path records. This checks and corrects path names that do
1201 not have a trailing slash. They should.
1202 \item Duplicate path records. This can happen if you accidentally run two
1203 copies of Bacula at the same time, and they are both adding filenames
1204 simultaneously. It is a rare occurrence, but will create an inconsistent
1205 database. See the item above for why this occurs and how you know it is
1207 \item Orphaned JobMedia records. This happens when a Job record is deleted
1208 (perhaps by a user issued SQL statement), but the corresponding JobMedia
1209 record (one for each Volume used in the Job) was not deleted. Normally, this
1210 should not happen, and even if it does, these records generally do not take
1211 much space in your database. However, by running this check, you can
1212 eliminate any such orphans.
1213 \item Orphaned File records. This happens when a Job record is deleted
1214 (perhaps by a user issued SQL statement), but the corresponding File record
1215 (one for each Volume used in the Job) was not deleted. Note, searching for
1216 these records can be {\bf very} time consuming (i.e. it may take hours) for a
1217 large database. Normally this should not happen as Bacula takes care to
1218 prevent it. Just the same, this check can remove any orphaned File records.
1219 It is recommended that you run this once a year since orphaned File records
1220 can take a large amount of space in your database. You might
1221 want to ensure that you have indexes on JobId, FilenameId, and
1222 PathId for the File table in your catalog before running this
1224 \item Orphaned Path records. This condition happens any time a directory is
1225 deleted from your system and all associated Job records have been purged.
1226 During standard purging (or pruning) of Job records, Bacula does not check
1227 for orphaned Path records. As a consequence, over a period of time, old
1228 unused Path records will tend to accumulate and use space in your database.
1229 This check will eliminate them. It is recommended that you run this
1230 check at least once a year.
1231 \item Orphaned Filename records. This condition happens any time a file is
1232 deleted from your system and all associated Job records have been purged.
1233 This can happen quite frequently as there are quite a large number of files
1234 that are created and then deleted. In addition, if you do a system update or
1235 delete an entire directory, there can be a very large number of Filename
1236 records that remain in the catalog but are no longer used.
1238 During standard purging (or pruning) of Job records, Bacula does not check
1239 for orphaned Filename records. As a consequence, over a period of time, old
1240 unused Filename records will accumulate and use space in your database. This
1241 check will eliminate them. It is strongly recommended that you run this check
1242 at least once a year, and for large database (more than 200 Megabytes), it is
1243 probably better to run this once every 6 months.
1244 \item Orphaned Client records. These records can remain in the database long
1245 after you have removed a client.
1246 \item Orphaned Job records. If no client is defined for a job or you do not
1247 run a job for a long time, you can accumulate old job records. This option
1248 allow you to remove jobs that are not attached to any client (and thus
1250 \item All Admin records. This command will remove all Admin records,
1251 regardless of their age.
1252 \item All Restore records. This command will remove all Restore records,
1253 regardless of their age.
1257 If you are using Mysql, dbcheck will ask you if you want to create temporary
1258 indexes to speed up orphaned Path and Filename elimination.
1260 Mostly for PostgreSQL users, we provide a pure SQL script dbcheck replacement
1261 in \url{examples/database/dbcheck.sql} that works with global queries instead
1262 of many small queries like dbcheck. Execution instructions are at the top of
1263 the script and you will need to type \texttt{COMMIT} at the end to validate
1266 If you are using bweb or brestore, don't eliminate orphaned Path, else you will
1267 have to rebuild \texttt{brestore\_pathvisibility} and
1268 \texttt{brestore\_pathhierarchy} indexes.
1270 By the way, I personally run dbcheck only where I have messed up
1271 my database due to a bug in developing Bacula code, so normally
1272 you should never need to run dbcheck in spite of the
1273 recommendations given above, which are given so that users don't
1274 waste their time running dbcheck too often.
1278 \index[general]{bregex}
1279 \index[general]{program!bregex}
1281 {\bf bregex} is a simple program that will allow you to test
1282 regular expressions against a file of data. This can be useful
1283 because the regex libraries on most systems differ, and in
1284 addition, regex expressions can be complicated.
1286 {\bf bregex} is found in the src/tools directory and it is
1287 normally installed with your system binaries. To run it, use:
1290 Usage: bregex [-d debug_level] -f <data-file>
1291 -f specify file of data to be matched
1292 -l suppress line numbers
1293 -n print lines that do not match
1294 -? print this message.
1297 The \lt{}data-file\gt{} is a filename that contains lines
1298 of data to be matched (or not) against one or more patterns.
1299 When the program is run, it will prompt you for a regular
1300 expression pattern, then apply it one line at a time against
1301 the data in the file. Each line that matches will be printed
1302 preceded by its line number. You will then be prompted again
1303 for another pattern.
1305 Enter an empty line for a pattern to terminate the program. You
1306 can print only lines that do not match by using the -n option,
1307 and you can suppress printing of line numbers with the -l option.
1309 This program can be useful for testing regex expressions to be
1310 applied against a list of filenames.
1314 \index[general]{bwild}
1315 \index[general]{program!bwild}
1317 {\bf bwild} is a simple program that will allow you to test
1318 wild-card expressions against a file of data.
1320 {\bf bwild} is found in the src/tools directory and it is
1321 normally installed with your system binaries. To run it, use:
1324 Usage: bwild [-d debug_level] -f <data-file>
1325 -f specify file of data to be matched
1326 -l suppress line numbers
1327 -n print lines that do not match
1328 -? print this message.
1331 The \lt{}data-file\gt{} is a filename that contains lines
1332 of data to be matched (or not) against one or more patterns.
1333 When the program is run, it will prompt you for a wild-card
1334 pattern, then apply it one line at a time against
1335 the data in the file. Each line that matches will be printed
1336 preceded by its line number. You will then be prompted again
1337 for another pattern.
1339 Enter an empty line for a pattern to terminate the program. You
1340 can print only lines that do not match by using the -n option,
1341 and you can suppress printing of line numbers with the -l option.
1343 This program can be useful for testing wild expressions to be
1344 applied against a list of filenames.
1348 \index[general]{Testfind}
1349 \index[general]{program!testfind}
1351 {\bf testfind} permits listing of files using the same search engine that is
1352 used for the {\bf Include} resource in Job resources. Note, much of the
1353 functionality of this program (listing of files to be included) is present in
1355 \ilink{estimate command}{estimate} in the Console program.
1357 The original use of testfind was to ensure that Bacula's file search engine
1358 was correct and to print some statistics on file name and path length.
1359 However, you may find it useful to see what bacula would do with a given {\bf
1360 Include} resource. The {\bf testfind} program can be found in the {\bf
1361 \lt{}bacula-source\gt{}/src/tools} directory of the source distribution.
1362 Though it is built with the make process, it is not normally "installed".
1368 Usage: testfind [-d debug_level] [-] [pattern1 ...]
1369 -a print extended attributes (Win32 debug)
1370 -dnn set debug level to nn
1371 - read pattern(s) from stdin
1372 -? print this message.
1373 Patterns are used for file inclusion -- normally directories.
1374 Debug level>= 1 prints each file found.
1375 Debug level>= 10 prints path/file for catalog.
1376 Errors are always printed.
1377 Files/paths truncated is a number with len> 255.
1378 Truncation is only in the catalog.
1382 Where a pattern is any filename specification that is valid within an {\bf
1383 Include} resource definition. If none is specified, {\bf /} (the root
1384 directory) is assumed. For example:
1392 Would print the following:
1398 Lnk: /bin/bash2 -> bash
1399 Lnk: /bin/sh -> bash
1407 Reg: /bin/aumix-minimal
1409 Lnka: /bin/gawk-3.1.0 -> /bin/gawk
1419 Even though {\bf testfind} uses the same search engine as {\bf Bacula}, each
1420 directory to be listed, must be entered as a separate command line entry or
1421 entered one line at a time to standard input if the {\bf -} option was
1424 Specifying a debug level of one (i.e. {\bf -d1}) on the command line will
1425 cause {\bf testfind} to print the raw filenames without showing the Bacula
1426 internal file type, or the link (if any). Debug levels of 10 or greater cause
1427 the filename and the path to be separated using the same algorithm that is
1428 used when putting filenames into the Catalog database.
