Next: The Restore Command Up: Bacula User's Guide Previous: Monitor Configuration Contents Index
The Bacula Console (sometimes called the User Agent) is a program that allows the user or the System Administrator, to interact with the Bacula Director daemon while the daemon is running.
The current Bacula Console comes in two versions: a shell interface (TTY style), and a GNOME GUI interface. Both permit the administrator or authorized users to interact with Bacula. You can determine the status of a particular job, examine the contents of the Catalog as well as perform certain tape manipulations with the Console program.
In addition, there is a bwx-console built with wxWidgets that allows a graphic restore of files. As of version 1.34.1 it is in an early stage of development, but it already is quite useful. Unfortunately, it has not been enhanced for some time now.
Since the Console program interacts with the Director through the network, your Console and Director programs do not necessarily need to run on the same machine.
In fact, a certain minimal knowledge of the Console program is needed in order for Bacula to be able to write on more than one tape, because when Bacula requests a new tape, it waits until the user, via the Console program, indicates that the new tape is mounted.
When the Console starts, it reads a standard Bacula configuration file named bconsole.conf or bgnome-console.conf in the case of the GNOME Console version. This file allows default configuration of the Console, and at the current time, the only Resource Record defined is the Director resource, which gives the Console the name and address of the Director. For more information on configuration of the Console program, please see the Console Configuration File Chapter of this document.
The console program can be run with the following options:
Usage: bconsole [-s] [-c config_file] [-d debug_level]
-c <file> set configuration file to file
-dnn set debug level to nn
-n no conio
-s no signals
-t test - read configuration and exit
-? print this message.
After launching the Console program (bconsole), it will prompt you for the next command with an asterisk (*). (Note, in the GNOME version, the prompt is not present; you simply enter the commands you want in the command text box at the bottom of the screen.) Generally, for all commands, you can simply enter the command name and the Console program will prompt you for the necessary arguments. Alternatively, in most cases, you may enter the command followed by arguments. The general format is:
<command> <keyword1>[=<argument1>] <keyword2>[=<argument2>] ...
where command is one of the commands listed below; keyword is one of the keywords listed below (usually followed by an argument); and argument is the value. The command may be abbreviated to the shortest unique form. If two commands have the same starting letters, the one that will be selected is the one that appears first in the help listing. If you want the second command, simply spell out the full command. None of the keywords following the command may be abbreviated.
For example:
list files jobid=23
will list all files saved for JobId 23. Or:
show pools
will display all the Pool resource records.
The maximum command line length is limited to 511 characters, so if you are scripting the console, you may need to take some care to limit the line length.
Normally, you simply enter quit or exit and the Console program will terminate. However, it waits until the Director acknowledges the command. If the Director is already doing a lengthy command (e.g. prune), it may take some time. If you want to immediately terminate the Console program, enter the .quit command.
There is currently no way to interrupt a Console command once issued (i.e. Ctrl-C does not work). However, if you are at a prompt that is asking you to select one of several possibilities and you would like to abort the command, you can enter a period (.), and in most cases, you will either be returned to the main command prompt or if appropriate the previous prompt (in the case of nested prompts). In a few places such as where it is asking for a Volume name, the period will be taken to be the Volume name. In that case, you will most likely be able to cancel at the next prompt.
jobid=536
Please note, this list is incomplete as it is currently in the process of being created and is not currently totally in alphabetic order ...
The following commands are currently implemented:
Normally, the label command is used rather than this command because the label command labels the physical media (tape, disk, DVD, ...) and does the equivalent of the add command. The add command affects only the Catalog and not the physical media (data on Volumes). The physical media must exist and be labeled before use (usually with the label command). This command can, however, be useful if you wish to add a number of Volumes to the Pool that will be physically labeled at a later time. It can also be useful if you are importing a tape from another site. Please see the label command below for the list of legal characters in a Volume name.
When autodisplay is turned off, you must explicitly retrieve the messages with the messages command. When autodisplay is turned on, the messages will be displayed on the console as they are received.
Once a Job is marked to be canceled, it may take a bit of time (generally within a minute) before it actually terminates, depending on what operations it is doing.
When starting a Job, if Bacula determines that there is no Pool record in the database, but there is a Pool resource of the appropriate name, it will create it for you. If you want the Pool record to appear in the database immediately, simply use this command to force it to be created.
If the keyword Volume appears on the command line, the named Volume will be deleted from the catalog, if the keyword Pool appears on the command line, a Pool will be deleted, and if the keyword Job appears on the command line, a Job and all its associated records (File and JobMedia) will be deleted from the catalog. The full form of this command is:
delete pool=<pool-name>
or
delete volume=>volume-name> pool=>pool-name> or
delete JobId=>job-id> JobId=>job-id2> ... or
delete Job JobId=n,m,o-r,t ...
The first form deletes a Pool record from the catalog database. The second form deletes a Volume record from the specified pool in the catalog database. The third form deletes the specified Job record from the catalog database. The last form deletes JobId records for JobIds n, m, o, p, q, r, and t. Where each one of the n,m,... is, of course, a number. That is a "delete jobid" accepts lists and ranges of jobids.
Optionally you may specify the keyword listing in which case, all the files to be backed up will be listed. Note, it could take quite some time to display them if the backup is large. The full form is:
estimate job=<job-name> listing client=<client-name>
fileset=<fileset-name> level=<level-name>
Specification of the job is sufficient, but you can also override the client, fileset and/or level by specifying them on the estimate command line.
As an example, you might do:
@output /tmp/listing
estimate job=NightlySave listing level=Incremental
@output
which will do a full listing of all files to be backed up for the Job NightlySave during an Incremental save and put it in the file /tmp/listing. Note, the byte estimate provided by this command is based on the file size contained in the directory item. This can give wildly incorrect estimates of the actual storage used if there are sparse files on your systems. Sparse files are often found on 64 bit systems for certain system files. The size that is returned is the size Bacula will backup if the sparse option is not specified in the FileSet. There is currently no way to get an estimate of the real file size that would be found should the sparse option be enabled.
label storage=>storage-name> volume=>volume-name>
slot=>slot>
If you leave out any part, you will be prompted for it. The media type is automatically taken from the Storage resource definition that you supply. Once the necessary information is obtained, the Console program contacts the specified Storage daemon and requests that the Volume be labeled. If the Volume labeling is successful, the Console program will create a Volume record in the appropriate Pool.
The Volume name is restricted to letters, numbers, and the special characters hyphen (-), underscore (_), colon (:), and period (.). All other characters including a space are invalid. This restriction is to ensure good readability of Volume names to reduce operator errors.
Please note, when labeling a blank tape, Bacula will get read I/O error when it attempts to ensure that the tape is not already labeled. If you wish to avoid getting these messages, please write an EOF mark on your tape before attempting to label it:
mt rewind
mt weof
The label command can fail for a number of reasons:
There are two ways to relabel a volume that already has a Bacula label. The brute force method is to write an end of file mark on the tape using the system mt program, something like the following:
mt -f /dev/st0 rewind
mt -f /dev/st0 weof
For a disk volume, you would manually delete the Volume.
Then you use the label command to add a new label. However, this could leave traces of the old volume in the catalog.
The preferable method to relabel a Volume is to first purge the volume, either automatically, or explicitly with the purge command, then use the relabel command described below.
If your autochanger has barcode labels, you can label all the Volumes in your autochanger one after another by using the label barcodes command. For each tape in the changer containing a barcode, Bacula will mount the tape and then label it with the same name as the barcode. An appropriate Media record will also be created in the catalog. Any barcode that begins with the same characters as specified on the "CleaningPrefix=xxx" directive in the Director's Pool resource, will be treated as a cleaning tape, and will not be labeled. However, an entry for the cleaning tape will be created in the catalog. For example with:
Pool {
Name ...
Cleaning Prefix = "CLN"
}
Any slot containing a barcode of CLNxxxx will be treated as a cleaning tape and will not be mounted. Note, the full form of the command is:
label storage=xxx pool=yyy slots=1-5,10 barcodes
list jobs
list jobid=<id> (list jobid id)
list ujobid<unique job name> (list job with unique name)
list job=<job-name> (list all jobs with "job-name")
list jobname=<job-name> (same as above)
In the above, you can add "limit=nn" to limit the output to
nn jobs.
list jobmedia
list jobmedia jobid=<id>
list jobmedia job=<job-name>
list files jobid=<id>
list files job=<job-name>
list pools
list clients
list jobtotals
list volumes
list volumes jobid=<id>
list volumes pool=<pool-name>
list volumes job=<job-name>
list volume=<volume-name>
list nextvolume job=<job-name>
list nextvol job=<job-name>
list nextvol job=<job-name> days=nnn
What most of the above commands do should be more or less obvious. In general if you do not specify all the command line arguments, the command will prompt you for what is needed.
The list nextvol command will print the Volume name to be used by the specified job. You should be aware that exactly what Volume will be used depends on a lot of factors including the time and what a prior job will do. It may fill a tape that is not full when you issue this command. As a consequence, this command will give you a good estimate of what Volume will be used but not a definitive answer. In addition, this command may have certain side effect because it runs through the same algorithm as a job, which means it may automatically purge or recycle a Volume. By default, the job specified must run within the next two days or no volume will be found. You can, however, use the days=nnn specification to specify up to 50 days. For example, if on Friday, you want to see what Volume will be needed on Monday, for job MyJob, you would use list nextvol job=MyJob days=3.
If you wish to add specialized commands that list the contents of the catalog, you can do so by adding them to the query.sql file. However, this takes some knowledge of programming SQL. Please see the query command below for additional information. See below for listing the full contents of a catalog record with the llist command.
As an example, the command list pools might produce the following output:
+------+---------+---------+---------+----------+-------------+ | PoId | Name | NumVols | MaxVols | PoolType | LabelFormat | +------+---------+---------+---------+----------+-------------+ | 1 | Default | 0 | 0 | Backup | * | | 2 | Recycle | 0 | 8 | Backup | File | +------+---------+---------+---------+----------+-------------+
As mentioned above, the list command lists what is in the database. Some things are put into the database immediately when Bacula starts up, but in general, most things are put in only when they are first used, which is the case for a Client as with Job records, etc.
Bacula should create a client record in the database the first time you run a job for that client. Doing a status will not cause a database record to be created. The client database record will be created whether or not the job fails, but it must at least start. When the Client is actually contacted, additional info from the client will be added to the client record (a "uname -a" output).
If you want to see what Client resources you have available in your conf file, you use the Console command show clients.
If instead of the list pools as in the example above, you enter llist pools you might get the following output:
PoolId: 1
Name: Default
NumVols: 0
MaxVols: 0
UseOnce: 0
UseCatalog: 1
AcceptAnyVolume: 1
VolRetention: 1,296,000
VolUseDuration: 86,400
MaxVolJobs: 0

AutoPrune: 0
Recycle: 1
PoolType: Backup
LabelFormat: File
mount storage=<storage-name> [ slot=<num> ] [ drive=<num> ]
mount [ jobid=<id> | job=<job-name> ]
If you have specified Automatic Mount = yes in the Storage daemon's Device resource, under most circumstances, Bacula will automatically access the Volume unless you have explicitly unmounted it in the Console program.
python restart
This causes the Python interpreter in the Director to be reinitialized. This can be helpful for testing because once the Director starts and the Python interpreter is initialized, there is no other way to make it accept any changes to the startup script DirStartUp.py. For more details on Python scripting, please see the Python Scripting chapter of this manual.
prune files|jobs|volume client=<client-name> volume=<volume-name>
For a Volume to be pruned, the VolStatus must be Full, Used, or Append, otherwise the pruning will not take place.
purge files jobid=<jobid>|job=<job-name>|client=<client-name>
purge jobs client=<client-name> (of all jobs)
purge volume|volume=<vol-name> (of all jobs)
For the purge command to work on Volume Catalog database records the VolStatus must be Append, Full, Used, or Error.
The actual data written to the Volume will be unaffected by this command.
relabel storage=<storage-name> oldvolume=<old-volume-name> volume=<newvolume-name>
If you leave out any part, you will be prompted for it. In order for the Volume (old-volume-name) to be relabeled, it must be in the catalog, and the volume status must be marked Purged or Recycle. This happens automatically as a result of applying retention periods, or you may explicitly purge the volume using the purge command.
Once the volume is physically relabeled, the old data previously written on the Volume is lost and cannot be recovered.
release storage=<storage-name>
After a release command, the device is still kept open by Bacula (unless Always Open is set to No in the Storage Daemon's configuration) so it cannot be used by another program. However, with some tape drives, the operator can remove the current tape and to insert a different one, and when the next Job starts, Bacula will know to re-read the tape label to find out what tape is mounted. If you want to be able to use the drive with another program (e.g. mt), you must use the unmount command to cause Bacula to completely release (close) the device.
While it is possible to reload the Director's configuration on the fly, even while jobs are executing, this is a complex operation and not without side effects. Accordingly, if you have to reload the Director's configuration while Bacula is running, it is advisable to restart the Director at the next convenient opportunity.
restore storage=<storage-name> client=<backup-client-name> where=<path> pool=<pool-name> fileset=<fileset-name> restoreclient=<restore-client-name> select current all done
Where current, if specified, tells the restore command to automatically select a restore to the most current backup. If not specified, you will be prompted. The all specification tells the restore command to restore all files. If it is not specified, you will be prompted for the files to restore. For details of the restore command, please see the Restore Chapter of this manual.
The client keyword initially specifies the client from which the backup was made and the client to which the restore will be make. However, if the restoreclient keyword is specified, then the restore is written to that client.
run job=<job-name> client=<client-name> fileset=<FileSet-name> level=<level-keyword> storage=<storage-name> where=<directory-prefix> when=<universal-time-specification> yes
Any information that is needed but not specified will be listed for selection, and before starting the job, you will be prompted to accept, reject, or modify the parameters of the job to be run, unless you have specified yes, in which case the job will be immediately sent to the scheduler.
On my system, when I enter a run command, I get the following prompt:
A job name must be specified.
The defined Job resources are:
1: Matou
2: Polymatou
3: Rufus
4: Minimatou
5: Minou
6: PmatouVerify
7: MatouVerify
8: RufusVerify
9: Watchdog
Select Job resource (1-9):
If I then select number 5, I am prompted with:
Run Backup job JobName: Minou FileSet: Minou Full Set Level: Incremental Client: Minou Storage: DLTDrive Pool: Default When: 2003-04-23 17:08:18 OK to run? (yes/mod/no):
If I now enter yes, the Job will be run. If I enter mod, I will be presented with the following prompt.
Parameters to modify:
1: Level
2: Storage
3: Job
4: FileSet
5: Client
6: When
7: Pool
Select parameter to modify (1-7):
If you wish to start a job at a later time, you can do so by setting the When time. Use the mod option and select When (no. 6). Then enter the desired start time in YYYY-MM-DD HH:MM:SS format.
setdebug level=nn [trace=0/1 client=<client-name> | dir | director | storage=<storage-name> | all]
If trace=1 is set, then tracing will be enabled, and the daemon will be placed in trace mode, which means that all debug output as set by the debug level will be directed to the file bacula.trace in the current directory of the daemon. Normally, tracing is needed only for Win32 clients where the debug output cannot be written to a terminal or redirected to a file. When tracing, each debug output message is appended to the trace file. You must explicitly delete the file when you are done.
Using this command, you can query the SQL catalog database directly. Note you should really know what you are doing otherwise you could damage the catalog database. See the query command below for simpler and safer way of entering SQL queries.
Depending on what database engine you are using (MySQL, PostgreSQL or SQLite), you will have somewhat different SQL commands available. For more detailed information, please refer to the MySQL, PostgreSQL or SQLite documentation.
status [all | dir=<dir-name> | director | client=<client-name> | storage=<storage-name> | days=nnn]
If you do a status dir, the console will list any currently running jobs, a summary of all jobs scheduled to be run in the next 24 hours, and a listing of the last ten terminated jobs with their statuses. The scheduled jobs summary will include the Volume name to be used. You should be aware of two things: 1. to obtain the volume name, the code goes through the same code that will be used when the job runs, but it does not do pruning nor recycling of Volumes; 2. The Volume listed is at best a guess. The Volume actually used may be different because of the time difference (more durations may expire when the job runs) and another job could completely fill the Volume requiring a new one.
In the Running Jobs listing, you may find the following types of information:
2507 Catalog MatouVerify.2004-03-13_05.05.02 is waiting execution
5349 Full CatalogBackup.2004-03-13_01.10.00 is waiting for higher
priority jobs to finish
5348 Differe Minou.2004-03-13_01.05.09 is waiting on max Storage jobs
5343 Full Rufus.2004-03-13_01.05.04 is running
Looking at the above listing from bottom to top, obviously JobId 5343 (Rufus) is running. JobId 5348 (Minou) is waiting for JobId 5343 to finish because it is using the Storage resource, hence the "waiting on max Storage jobs". JobId 5349 has a lower priority than all the other jobs so it is waiting for higher priority jobs to finish, and finally, JobId 2508 (MatouVerify) is waiting because only one job can run at a time, hence it is simply "waiting execution"
If you do a status dir, it will by default list the first occurrence of all jobs that are scheduled today and tomorrow. If you wish to see the jobs that are scheduled in the next three days (e.g. on Friday you want to see the first occurrence of what tapes are scheduled to be used on Friday, the weekend, and Monday), you can add the days=3 option. Note, a days=0 shows the first occurrence of jobs scheduled today only. If you have multiple run statements, the first occurrence of each run statement for the job will be displayed for the period specified.
If your job seems to be blocked, you can get a general idea of the problem by doing a status dir, but you can most often get a much more specific indication of the problem by doing a status storage=xxx. For example, on an idle test system, when I do status storage=File, I get:
status storage=File

Now, what this tells me is that no jobs are running and that none of the devices are in use. Now, if I unmount the autochanger, which will not be used in this example, and then start a Job that uses the File device, the job will block. When I re-issue the status storage command, I get for the Device status:
status storage=File
...
Device status:
Autochanger "DDS-4-changer" with devices:
"DDS-4" (/dev/nst0)
Device "DDS-4" (/dev/nst0) is not open.

No DEVICE structure.
Device "DVD-Writer" (/dev/hdc) is not open.
Device "File" (/tmp) is not open.
Device is BLOCKED waiting for media.
====
...
Now, here it should be clear that if a job were running that wanted to use the Autochanger (with two devices), it would block because the user unmounted the device. The real problem for the Job I started using the "File" device is that the device is blocked waiting for media -- that is Bacula needs you to label a Volume.
unmount storage=<storage-name> [ drive=<num> ] unmount [ jobid=<id> | job=<job-name> ]
Once you unmount a storage device, Bacula will no longer be able to use it until you issue a mount command for that device. If Bacula needs to access that device, it will block and issue mount requests periodically to the operator.
If the device you are unmounting is an autochanger, it will unload the drive you have specified on the command line. If no drive is specified, it will assume drive 1.
media, volume, pool, slots
In the case of updating a Volume, you will be prompted for which value you wish to change. The following Volume parameters may be changed:
Volume Status Volume Retention Period Volume Use Duration Maximum Volume Jobs Maximum Volume Files Maximum Volume Bytes Recycle Flag Recycle Pool Slot InChanger Flag Pool Volume Files Volume from Pool All Volumes from Pool All Volumes from all Pools
For slots update slots, Bacula will obtain a list of slots and their barcodes from the Storage daemon, and for each barcode found, it will automatically update the slot in the catalog Media record to correspond to the new value. This is very useful if you have moved cassettes in the magazine, or if you have removed the magazine and inserted a different one. As the slot of each Volume is updated, the InChanger flag for that Volume will also be set, and any other Volumes in the Pool that were last mounted on the same Storage device will have their InChanger flag turned off. This permits Bacula to know what magazine (tape holder) is currently in the autochanger.
If you do not have barcodes, you can accomplish the same thing in version 1.33 and later by using the update slots scan command. The scan keyword tells Bacula to physically mount each tape and to read its VolumeName.
For Pool update pool, Bacula will move the Volume record from its existing pool to the pool specified.
For Volume from Pool, All Volumes from Pool and All Volumes from all Pools, the following values are updated from the Pool record: Recycle, RecyclePool, VolRetention, VolUseDuration, MaxVolJobs, MaxVolFiles, and MaxVolBytes. (RecyclePool feature is available with bacula 2.1.4 or higher.)
The full form of the update command with all command line arguments is:
update volume=xxx pool=yyy slots volstatus=xxx VolRetention=ddd
VolUse=ddd MaxVolJobs=nnn MaxVolBytes=nnn Recycle=yes|no
slot=nnn enabled=n recyclepool=zzz
use <database-name>
The following queries are currently available (version 1.24):
Available queries: 1: List Job totals: 2: List where a file is saved: 3: List where the most recent copies of a file are saved: 4: List total files/bytes by Job: 5: List total files/bytes by Volume: 6: List last 20 Full Backups for a Client: 7: List Volumes used by selected JobId: 8: List Volumes to Restore All Files: 9: List where a File is saved: Choose a query (1-9):

There is a list of commands that are prefixed with a period (.). These commands are intended to be used either by batch programs or graphical user interface front-ends. They are not normally used by interactive users. Once GUI development begins, this list will be considerably expanded. The following is the list of dot commands:
.backups job=xxx list backups for specified job
.clients list all client names
.defaults client=xxx fileset=yyy list defaults for specified client
.die cause the Director to segment fault (for debugging)
.dir when in tree mode prints the equivalent to the dir command,
but with fields separated by commas rather than spaces.
.exit quit
.filesets list all fileset names
.help help command output
.jobs list all job names
.levels list all levels
.messages get quick messages
.msgs return any queued messages
.pools list all pool names
.quit quit
.status get status output
.storage return storage resource names
.types list job types
Normally, all commands entered to the Console program are immediately forwarded to the Director, which may be on another machine, to be executed. However, there is a small list of at commands, all beginning with an at character (@), that will not be sent to the Director, but rather interpreted by the Console program directly. Note, these commands are implemented only in the tty console program and not in the GNOME Console. These commands are:
@output /dev/null
commands ...
@output
You can automate many Console tasks by running the console program from a shell script. For example, if you have created a file containing the following commands:
./bconsole -c ./bconsole.conf <<END_OF_DATA unmount storage=DDS-4 quit END_OF_DATA
when that file is executed, it will unmount the current DDS-4 storage device. You might want to run this command during a Job by using the RunBeforeJob or RunAfterJob records.
It is also possible to run the Console program from file input where the file contains the commands as follows:
./bconsole -c ./bconsole.conf <filename
where the file named filename contains any set of console commands.
As a real example, the following script is part of the Bacula regression tests. It labels a volume (a disk volume), runs a backup, then does a restore of the files saved.
bin/bconsole -c bin/bconsole.conf <<END_OF_DATA @output /dev/null messages @output /tmp/log1.out label volume=TestVolume001 run job=Client1 yes wait messages @# @# now do a restore @# @output /tmp/log2.out restore current all yes wait messages @output quit END_OF_DATA
The output from the backup is directed to /tmp/log1.out and the output from the restore is directed to /tmp/log2.out. To ensure that the backup and restore ran correctly, the output files are checked with:
grep "^Termination: *Backup OK" /tmp/log1.out backupstat=$? grep "^Termination: *Restore OK" /tmp/log2.out restorestat=$?
If you have used the label command to label a Volume, it will be automatically added to the Pool, and you will not need to add any media to the pool.
Alternatively, you may choose to add a number of Volumes to the pool without labeling them. At a later time when the Volume is requested by Bacula you will need to label it.
Before adding a volume, you must know the following information:
For example, to add media to a Pool, you would issue the following commands to the console program:

Notice that the console program automatically appended a number to the base Volume name that you specify (Save in this case). If you don't want it to append a number, you can simply answer 0 (zero) to the question "Enter number of Media volumes to create. Max=1000:", and in this case, it will create a single Volume with the exact name you specify.
