\addcontentsline{toc}{subsection}{General}

The {\bf 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 wx-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. 

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. 

\subsection*{Console Configuration}

\addcontentsline{toc}{subsection}{Console Configuration}

When the Console starts, it reads a standard Bacula configuration file named
{\bf bconsole.conf} or {\bf gnome-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 
\ilink{Console Configuration File}{_ChapterStart36} Chapter of
this document.

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: 

\footnotesize
\begin{verbatim}
 <command> <keyword1>[=<argument1>] <keyword2>[=<argument2>] ...
\end{verbatim}
\normalsize

where {\bf command} is one of the commands listed below; {\bf keyword} is one
of the keywords listed below (usually followed by an argument); and {\bf
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 {\bf 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: 

\footnotesize
\begin{verbatim}
list files jobid=23
\end{verbatim}
\normalsize

will list all files saved for JobId 23. Or: 

\footnotesize
\begin{verbatim}
show pools
\end{verbatim}
\normalsize

will display all the Pool resource records.

\addcontentsline{toc}{subsection}{Stopping the Console Program}

Normally, you simply enter {\bf quit} or {\bf 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
{\bf .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 ({\bf .}), 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. 

There are three keywords used to refer to Jobs that must be clearly
understood. They are the following:
\begin{description}
\item [jobid]
  The JobId is the numeric jobid that is printed in the Job
  Report output. It is the index of the database record for the
  given job. While it is unique for all the existing Job records
  in the catalog database, the same JobId can be reused once a
  Job is removed from the catalog. Probably you will refer
  specific Jobs that ran using their numeric JobId.
\item [ujobid]
  The ujobid is a unique job identification that is printed
  in the Job Report output. At the current time, it consists
  of the Job name (from the Name directive for the job) appended
  with the date and time the job was run. This keyword is useful
  if you want to completely identify the Job instance run.
\item [job | jobname]
  The Job or Jobname keyword refers to the name you specified
  in the Job resource, and hence it refers to any number of
  Jobs that ran.  It is typically useful if you want to list
  all jobs of a particular name.
\end{description}

\addcontentsline{toc}{subsection}{Alphabetic List of Console Commands}

The following commands are currently implemented: 

\begin{description}
\item [{add [pool=\lt{}pool-name\gt{} storage=\lt{}storage\gt{}
   jobid=\lt{}JobId\gt{}]} ]
   \index[console]{add}
This command is used to add Volumes to an existing Pool. The  Volume names
entered are placed in the Catalog and thus become  available for backup
operations. Normally, the {\bf label}  command is used rather than this
command because the {\bf label}  command labels the physical media (tape) and
does the equivalent of  the {\bf add} command. This 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 {\bf 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 {\bf label}
command below for  the list of legal characters in a Volume name.  

\item [autodisplay on/off]
   \index[console]{autodisplay on/off}
   This command accepts {\bf on} or {\bf off} as an argument, and turns
   auto-display of messages on or off respectively.  The default for the
   console program is {\bf off}, which means that you will be notified when
   there are console messages pending, but they will not automatically be
   displayed.  The default for the gnome-console program is {\bf on}, which
   means that messages will be displayed when they are received (usually
   within 5 seconds of them being generated).

   When autodisplay is turned off, you must explicitly retrieve the
   messages with the {\bf messages} command.  When autodisplay is turned
   on, the messages will be displayed on the console as they are received.

\item [automount on/off]
   \index[console]{automount on/off}
   This command accepts {\bf on} or {\bf off} as the argument, and turns
   auto-mounting of the tape after a {\bf label} command on or off
   respectively.  The default is {\bf on}.  If {\bf automount} is turned
   off, you must explicitly {\bf mount} the tape after a label command to
   use it.

\item [{cancel [jobid=\lt{}number\gt{} job=\lt{}job-name\gt{} ujobid=\lt{}unique-jobid\gt{}]}]
   \index[console]{cancel jobid}
   This command is used to cancel a job and accepts {\bf jobid=nnn} or {\bf
   job=xxx} as an argument where nnn is replaced by the JobId and xxx is
   replaced by the job name.  If you do not specify a keyword, the Console
   program will prompt you with the names of all the active jobs allowing
   you to choose one.

   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.

\item [{ create [pool=\lt{}pool-name\gt{}]}]
   \index[console]{create pool}
   This command is used to create a Pool record in the database using the
   Pool resource record defined in the Director's configuration file.  So
   in a sense, this command simply transfers the information from the Pool
   resource in the configuration file into the Catalog.  Normally this
   command is done automatically for you when the Director starts providing
   the Pool is referenced within a Job resource.  If you use this command
   on an existing Pool, it will automatically update the Catalog to have
   the same information as the Pool resource.  After creating a Pool, you
   will most likely use the {\bf label} command to label one or more
   volumes and add their names to the Media database.

   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.

\item [{ delete [volume=\lt{}vol-name\gt{} pool=\lt{}pool-name\gt{}  job
   jobid=\lt{}id\gt{}] }]
   \index[console]{delete}
   The delete command is used to delete a Volume, Pool or Job record from
   the Catalog as well as all associated catalog Volume records that were
   created.  This command operates only on the Catalog database and has no
   effect on the actual data written to a Volume.  This command can be
   dangerous and we strongly recommend that you do not use it unless you
   know what you are doing.

   If the keyword {\bf Volume} appears on the command line, the named
   Volume will be deleted from the catalog, if the keyword {\bf Pool}
   appears on the command line, a Pool will be deleted, and if the keyword
   {\bf 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=\lt{}pool-name\gt{}

   or  

delete volume=\lt{}volume-name\gt{} pool=\lt{}pool-name\gt{}  or  

delete JobId=\lt{}job-id\gt{} JobId=\lt{}job-id2\gt{} ...  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.

\label{estimate}
\item [estimate]
   \index[console]{estimate}
   Using this command, you can get an idea how many files will be backed
   up, or if you are unsure about your Include statements in your FileSet,
   you can test them without doing an actual backup.  The default is to
   assume a Full backup.  However, you can override this by specifying a
   {\bf level=Incremental} or {\bf level=Differential} on the command line.
   A Job name must be specified or you will be prompted for one, and
   optionally a Client and FileSet may be specified on the command line.
   It then contacts the client which computes the number of files and bytes
   that would be backed up.  Please note that this is an estimate
   calculated from the number of blocks in the file rather than by reading
   the actual bytes.  As such, the estimated backup size will generally be
   larger than an actual backup.

   Optionally you may specify the keyword {\bf 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=\lt{}job-name\gt{} listing client=\lt{}client-name\gt{} 
fileset=\lt{}fileset-name\gt{} level=\lt{}level-name\gt{}  

   Specification of the {\bf 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:  

\footnotesize
\begin{verbatim}
     @output /tmp/listing
     estimate job=NightlySave listing level=Incremental
     @output
\end{verbatim}
\normalsize

which will do a full listing of all files to be backed up for the  Job {\bf
NightlySave} during an Incremental save and put it in the  file {\bf
/tmp/listing}. 

\item [help]
   \index[console]{help}
   This command displays the list of commands available.  

\item [label]
   \index[console]{label}
   \index[console]{relabel}
   \index[general]{label}
   \index[general]{relabel}
   This command is used to label physical volumes.  The full form of this command
   is:

label storage=\lt{}storage-name\gt{} volume=\lt{}volume-name\gt{}
slot=\lt{}slot\gt{}  

   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 tape be
   labeled.  If the tape 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 ({\bf -}), underscore ({\bf \_}), colon ({\bf :}), and
   period ({\bf .}).  All other characters including a space are illegal.
   This restriction is to ensure good readability of Volume names to reduce
   operator errors.

   Please note, when labeling a blank tape, Bacula will get {\bf read I/O
   error} when it attempts to ensure that the tape is already labeled.  If
   you wish to avoid getting these messages, please write and EOF mark on
   your tape before attempting to label it:

\footnotesize
\begin{verbatim}
       mt rewind
       mt weof
       
\end{verbatim}
\normalsize

The label command can fail for a number of reasons:  

\begin{enumerate}
\item The Volume name you specify is already in the  Volume database.  
\item The Storage daemon has a tape already mounted on the  device, in which
   case you must {\bf unmount}  the device, insert a blank tape, then do the 
   {\bf label} command.  
\item The tape in the device is already a Bacula labeled tape.  (Bacula will
   never relabel a Bacula labeled tape unless it is recycled and you use the
   {\bf relabel} command).  
\item There is no tape in the drive.  
\end{enumerate}

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 {\bf mt} program, something like the  following:  

\footnotesize
\begin{verbatim}
       mt -f /dev/st0 rewind
       mt -f /dev/st0 weof
\end{verbatim}
\normalsize

Then you use the {\bf 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 tape is to first {\bf purge}  the volume,
either automatically, or explicitly with the  {\bf purge} command, then use
the {\bf 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  {\bf 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:  

\footnotesize
\begin{verbatim}
        Pool {
          Name ...
          Cleaning Prefix = "CLN"
        }
        
\end{verbatim}
\normalsize

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: 

\footnotesize
\begin{verbatim}
update storage=xxx pool=yyy slots=1-5,10 barcodes
\end{verbatim}
\normalsize

\item [list]
   \index[console]{list}
   The list command lists the requested contents of the Catalog.  The
   various fields of each record are listed on a single line.  The various
   forms of the list command are:
\footnotesize
\begin{verbatim}
   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



\end{verbatim}
\normalsize

   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 {\bf 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
   {\bf 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 {\bf 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 {\bf query.sql} file.
   However, this takes some knowledge of programming SQL. Please see the
   {\bf query} command below for additional information.  See below for
   listing the full contents of a catalog record with the {\bf llist}
   command.

   As an example, the command {\bf list pools} might produce  the following
   output: 

\footnotesize
\begin{verbatim}
+------+---------+---------+---------+----------+-------------+
| PoId | Name    | NumVols | MaxVols | PoolType | LabelFormat |
+------+---------+---------+---------+----------+-------------+
|    1 | Default |       0 |       0 | Backup   | *           |
|    2 | Recycle |       0 |       8 | Backup   | File        |
+------+---------+---------+---------+----------+-------------+
\end{verbatim}
\normalsize

   As mentioned above, the {\bf 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 {\bf 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 {\bf show clients}.

\item [llist]
   \index[console]{llist}
   The llist or "long list" command takes all the same arguments that the
   list command described above does.  The difference is that the llist
   command list the full contents of each database record selected.  It
   does so by listing the various fields of the record vertically, with one
   field per line.  It is possible to produce a very large number of output
   lines with this command.

   If instead of the {\bf list pools} as in the example above, you enter
   {\bf llist pools} you might get the following output:

\footnotesize
\begin{verbatim}
          PoolId: 1
            Name: Default
         NumVols: 0
         MaxVols: 0
         UseOnce: 0
      UseCatalog: 1
 AcceptAnyVolume: 1
    VolRetention: 1,296,000
  VolUseDuration: 86,400
      MaxVolJobs: 0
     MaxVolBytes: 0
       AutoPrune: 0
         Recycle: 1
        PoolType: Backup
     LabelFormat: *
          PoolId: 2
            Name: Recycle
         NumVols: 0
         MaxVols: 8
         UseOnce: 0
      UseCatalog: 1
 AcceptAnyVolume: 1
    VolRetention: 3,600
  VolUseDuration: 3,600
      MaxVolJobs: 1
     MaxVolBytes: 0
       AutoPrune: 0
         Recycle: 1
        PoolType: Backup
     LabelFormat: File
      
\end{verbatim}
\normalsize

\item [messages]
   \index[console]{messages}
   This command causes any pending  console messages to be immediately displayed.
 

\item [mount]
   \index[console]{mount}
   The mount command is used to get Bacula to read a volume on a physical
   device.  It is a way to tell Bacula that you have mounted a tape and
   that Bacula should examine the tape.  This command is used only after
   there was no Volume in a drive and Bacula requests you to mount a new
   Volume or when you have specifically unmounted a Volume with the {\bf
   unmount} console command, which causes Bacula to close the drive.  If
   you have an autoloader, the mount command will not cause Bacula to
   operate the autoloader.  The various forms of the mount command are:

mount  storage=\lt{}storage-name\gt{}

mount [ jobid=\lt{}id\gt{} |  job=\lt{}job-name\gt{} ]

   If you have specified {\bf Automatic  Mount = yes} in the Storage daemon's
   Device resource,  under most circumstances, Bacula will automatically access 
   the Volume unless you have explicitly {\bf unmount}ed it in  the Console
   program. 

\item[python]
   \index[console]{python}
  The python command takes a single argument {\bf restart}:

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 {\bf DirStartUp.py}.  For more
   details on Python scripting, please see the \ilink{Python
   Scripting}{_ChapterStart60} chapter of this manual.

\label{ManualPruning}
\item [prune]
   \index[console]{prune}
   The Prune command allows you to safely remove expired database records
   from Jobs and Volumes.  This command works only on the Catalog database
   and does not affect data written to Volumes.  In all cases, the Prune
   command applies a retention period to the specified records.  You can
   Prune expired File entries from Job records; you can Prune expired Job
   records from the database, and you can Prune both expired Job and File
   records from specified Volumes.

prune files|jobs|volume client=\lt{}client-name\gt{} 
volume=\lt{}volume-name\gt{}  

   For a Volume to be pruned, the {\bf VolStatus} must be Full, Used, or
   Append, otherwise the pruning will not take place.

\item [purge]
   \index[console]{purge}
   The Purge command will delete associated Catalog database records from
   Jobs and Volumes without considering the retention period.  {\bf Purge}
   works only on the Catalog database and does not affect data written to
   Volumes.  This command can be dangerous because you can delete catalog
   records associated with current backups of files, and we recommend that
   you do not use it unless you know what you are doing.  The permitted
   forms of {\bf purge} are:

purge files jobid=\lt{}jobid\gt{}|job=\lt{}job-name\gt{}|client=\lt{}client-name\gt{} 

purge jobs client=\lt{}client-name\gt{} (of all jobs)

purge volume|volume=\lt{}vol-name\gt{} (of all jobs)

For the {\bf purge} command to work on Volume Catalog database  records the
{\bf VolStatus}  must be Append, Full, Used, or Error.  

The actual data written to the Volume will be unaffected by  this command.  

\item [relabel]
   \index[console]{relabel}
   \index[general]{relabel}
   This command is used to label physical volumes.  The full form of this
   command is:

relabel storage=\lt{}storage-name\gt{} oldvolume=\lt{}old-volume-name\gt{}  
    volume=\lt{}newvolume-name\gt{} 
 
   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 {\bf Purged} or {\bf Recycle}.
   This happens automatically as a result of applying retention periods, or
   you may explicitly purge the volume using the {\bf purge} command.

   Once the volume is physically relabeled, the old data previously written
   on the Volume is lost and cannot be recovered.

\item [release]
   \index[console]{release}
   This command is used to cause the Storage daemon to rewind (release) the
   current tape in the drive, and to re-read the Volume label the next time
   the tape is used.

release storage=\lt{}storage-name\gt{}  

   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.  {\bf mt}), you must use the {\bf unmount}
   command to cause Bacula to completely release (close) the device.

\item [reload]
  \index[console]{reload}
  The reload command causes the Director to re-read its configuration
  file and apply the new values. The new values will take effect     
  immediately for all new jobs.  However, if you change schedules,
  be aware that the scheduler pre-schedules jobs up to two hours in
  advance, so any changes that are to take place during the next two
  hours may be delayed.  Jobs that have already been scheduled to run
  (i.e. surpassed their requested start time) will continue with the
  old values.  New jobs will use the new values. Each time you issue
  a reload command while jobs are running, the prior config values   
  will queued until all jobs that were running before issuing
  the reload terminate, at which time the old config values will
  be released from memory. The Directory permits keeping up to
  10 prior set of configurations before it will refuse a reload
  command. Once at least one old set of config values has been
  released it will again accept new reload commands. 

   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.

\label{restore_command}
\item [restore]
   \index[console]{restore}
   The restore command allows you to select one or more Jobs (JobIds) to be
   restored using various methods.  Once the JobIds are selected, the File
   records for those Jobs are placed in an internal Bacula directory tree,
   and the restore enters a file selection mode that allows you to
   interactively walk up and down the file tree selecting individual files
   to be restored.  This mode is somewhat similar to the standard Unix {\bf
   restore} program's interactive file selection mode.

restore storage=\lt{}storage-name\gt{} client=\lt{}client-name\gt{} 
  where=\lt{}path\gt{} pool=\lt{}pool-name\gt{} fileset=\lt{}fileset-name\gt{} 
  select current all done  

   Where {\bf 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 {\bf 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 {\bf restore}
   command, please see the \ilink{Restore Chapter}{_ChapterStart13} of this
   manual.

\item [run]
   \index[console]{run}
   This command allows you to schedule jobs  to be run immediately. The full form
   of the command is:

run job=\lt{}job-name\gt{} client=\lt{}client-name\gt{}
  fileset=\lt{}FileSet-name\gt{}  level=\lt{}level-keyword\gt{}
  storage=\lt{}storage-name\gt{}  where=\lt{}directory-prefix\gt{}
  when=\lt{}universal-time-specification\gt{}  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 {\bf 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:  

\footnotesize
\begin{verbatim}
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):
     
\end{verbatim}
\normalsize

If I then select number 5, I am prompted with:  

\footnotesize
\begin{verbatim}
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):
     
\end{verbatim}
\normalsize

If I now enter {\bf yes}, the Job will be run. If I enter {\bf mod},  I will
be presented with the following prompt.  

\footnotesize
\begin{verbatim}
Parameters to modify:
     1: Level
     2: Storage
     3: Job
     4: FileSet
     5: Client
     6: When
     7: Pool
Select parameter to modify (1-7):
     
\end{verbatim}
\normalsize

If you wish to start a job at a later time, you can do so by setting  the When
time. Use the {\bf mod} option and select {\bf When} (no. 6).  Then enter the
desired start time in YYYY-MM-DD HH:MM:SS format.  

\item [setdebug]
   \index[dir]{setdebug}
   This command is used to set the debug level in each  daemon. The form of this
   command is:

setdebug level=nn [trace=0/1 client=\lt{}client-name\gt{} | dir | director |
  storage=\lt{}storage-name\gt{} | all]  

   If trace=1 is set, then the tracing will be enabled, and the daemon
   where the setdebug applies will be placed in trace mode, and all debug
   output will go to the file {\bf bacula.trace} in the current directory
   of the daemon.  Normally, tracing is used 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.

\item [show]
   \index[console]{show}
   The show command will list the Director's resource records as defined in
   the Director's configuration file (normally {\bf bacula-dir.conf}).
   This command is used mainly for debugging purposes by developers.  The
   following keywords are accepted on the show command line: directors,
   clients, counters, jobs, storages, catalogs, schedules, filesets,
   groups, pools, messages, all, help.  Please don't confuse this command
   with the {\bf list}, which displays the contents of the catalog.

\item [sqlquery]
   \index[dir]{sqlquery}
   The sqlquery command puts the Console program into SQL query mode where
   each line you enter is concatenated to the previous line until a
   semicolon (;) is seen.  The semicolon terminates the command, which is
   then passed directly to the SQL database engine.  When the output from
   the SQL engine is displayed, the formation of a new SQL command begins.
   To terminate SQL query mode and return to the Console command prompt,
   you enter a period (.) in column 1.

   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 {\bf 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.

\item [status]
   \index[dir]{status}
   This command will display the status of the next jobs that are scheduled
   during the next twenty-four hours as well as the status of currently
   running jobs.  The full form of this command is:

status [all | dir=\lt{}dir-name\gt{} | director | 
  client=\lt{}client-name\gt{} | storage=\lt{}storage-name\gt{} |
  days=nnn]

   If you do a {\bf 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 10 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, which
   means that it may prune or recycle a Volume; 2.  The Volume listed is
   only a best 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:


\footnotesize
\begin{verbatim}
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
\end{verbatim}
\normalsize

   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 {\bf 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 3 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 {\bf
   days=3} option.  Note, a {\bf 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.

\item [unmount]
   \index[console]{unmount}
   This command causes the indicated Bacula Storage  daemon to unmount the
   specified device. The forms of the command  are the same as the mount command:
\footnotesize
\begin{verbatim}
unmount storage=<storage-name>

unmount [ jobid=<id> | job=<job-name> ]
\end{verbatim}
\normalsize

\label{UpdateCommand}
\item [update]
   \index[console]{update}
   This command will update the catalog for either a specific Pool record, a Volume
   record, or the Slots in an  autochanger with barcode capability. In the case
   of updating a  Pool record, the new information will be automatically taken
   from  the corresponding Director's configuration resource record. It  can be
   used to increase the maximum number of volumes permitted or  to set a maximum
   number of volumes. The following main  keywords may be specified:  
\footnotesize
\begin{verbatim}
   media, volume, pool, slots  
\end{verbatim}
\normalsize

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:  

\footnotesize
\begin{verbatim}
 
   Volume Status
   Volume Retention Period
   Volume Use Duration
   Maximum Volume Jobs
   Maximum Volume Files
   Maximum Volume Bytes
   Recycle Flag
   Slot
   InChanger Flag
   Pool
   Volume Files
   Volume from Pool
   All Volumes from Pool
   
\end{verbatim}
\normalsize

   For slots {\bf 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 {\bf update slots scan} command.
   The {\bf scan} keyword tells Bacula to physically mount each tape and to
   read its VolumeName.

   For Pool {\bf update pool}, Bacula will move the Volume record from its
   existing pool to the pool specified.

   For {\bf Volume from Pool} and {\bf All Volumes from Pool}, the
   following values are updated from the Pool record: Recycle,
   VolRetention, VolUseDuration, MaxVolJobs, MaxVolFiles, and MaxVolBytes.

   The full form of the update command with all command line arguments is:

\footnotesize
\begin{verbatim}
       update volume=xxx pool=yyy slots volstatus=xxx VolRetention=ddd
         VolUse=ddd MaxVolJobs=nnn MaxVolBytes=nnn Recycle=yes|no
         slot=nnn
      
\end{verbatim}
\normalsize

\item [use]
   \index[console]{use }
   This command allows you to specify which Catalog  database to use. Normally,
you will be using only one database so  this will be done automatically. In
the case that you are using  more than one database, you can use this command
to switch from  one to another.  

use \lt{}database-name\gt{} 

\item [var]
   \label{var}
   \index[console]{var name }
   This command takes a string or quoted string and  does variable expansion on
   it the same way variable expansion  is done on the {\bf LabelFormat} string.
   Thus, for the  most part, you can test your LabelFormat strings. The
   difference  between the {\bf var} command and the actual LabelFormat process 
   is that during the var command, no job is running so "dummy"  values are
   used in place of Job specific variables. Generally,  however, you will get a
   good idea of what is going to happen  in the real case.  

\item [version]
   \index[console]{version }
   The command prints the Director's version.  

\item [quit]
   \index[console]{quit }
   This command terminates the console program. The  console program sends the
{\bf quit} request to the Director  and waits for acknowledgment. If the
Director is busy doing  a previous command for you that has not terminated, it
may  take some time. You may quit immediately by issuing the  {\bf .quit}
command (i.e. quit preceded by a period).  

\item [query]
   \index[console]{query }
   This command reads a predefined SQL query from  the query file (the name and
   location of the  query file is defined with the QueryFile resource record in 
   the Director's configuration file). You are prompted to select  a query from
   the file, and possibly enter one or more parameters,  then the command is
   submitted to the Catalog database SQL engine.  

The following queries are currently available (version 1.24):  

\footnotesize
\begin{verbatim}
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):
      
\end{verbatim}
\normalsize

\item [exit]
   \index[console]{exit }
   This command terminates the console program.  

\item [wait]
   \index[console]{wait }
   The wait command causes the Director to pause  until there are no jobs
running. This command is useful in  a batch situation such as regression
testing where you  wish to start a job and wait until that job completes 
before continuing.

\label{dotcommands}

\subsection*{Special dot Commands}
\index[general]{Commands!Special dot }
\index[general]{Special dot Commands }
\addcontentsline{toc}{subsection}{Special dot Commands}

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: 

\footnotesize
\begin{verbatim}
.backups job=xxx      list backups for specified job
.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.
.jobs                 list all job names

\label{atcommands}

\subsection*{Special At (@) Commands}
\index[general]{Commands!Special At @ }
\index[general]{Special At (@) Commands }
\addcontentsline{toc}{subsection}{Special At (@) Commands}

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 {\bf 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: 

\begin{description}

\item [@input \lt{}filename\gt{}]
   \index[console]{@input \lt{}filename\gt{} }
   Read and execute the commands  contained in the file specified.  

\item [@output \lt{}filename\gt{} w/a]
   \index[console]{@output \lt{}filename\gt{} w/a }
   Send all following output to the  filename specified either overwriting the
file (w) or appending to  the file (a). To redirect the output to the
terminal, simply enter  {\bf @output} without a filename specification.
WARNING: be careful  not to overwrite a valid file. A typical example during a
regression  test might be:  

\footnotesize
\begin{verbatim}
    @output /dev/null
    commands ...
    @output
    
\end{verbatim}
\normalsize

\item [@tee \lt{}filename\gt{} w/a]
   \index[console]{@tee \lt{}filename\gt{} w/a }
   Send all subsequent output to  both the specified file and the terminal. It is
   turned off by  specifying {\bf @tee} or {\bf @output} without a filename.  

\item [@sleep \lt{}seconds\gt{}]
   \index[console]{@sleep \lt{}seconds\gt{} }
   Sleep the specified number of seconds.  

\item [@time]
   \index[console]{@time }
   Print the current time and date.  

\item [@version]
   \index[console]{@version }
   Print the console's version.  

\item [@quit]
   \index[console]{@quit }

\label{scripting}

\subsection*{Running the Console Program from a Shell Script}
\index[general]{Script!Running the Console Program from a Shell }
\index[general]{Running the Console Program from a Shell Script }
\addcontentsline{toc}{subsection}{Running the Console Program from a Shell
Script}

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: 

\footnotesize
\begin{verbatim}
 ./bconsole -c ./bconsole.conf <<END_OF_DATA
 unmount storage=DDS-4
 quit
 END_OF_DATA
\end{verbatim}
\normalsize

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 {\bf
RunBeforeJob} or {\bf RunAfterJob} records. 

It is also possible to run the Console program from file input where the file
contains the commands as follows: 

\footnotesize
\begin{verbatim}
./bconsole -c ./bconsole.conf <filename
\end{verbatim}
\normalsize

where the file named {\bf 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. 

\footnotesize
\begin{verbatim}
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
\end{verbatim}
\normalsize

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: 

\footnotesize
\begin{verbatim}
grep "^Termination: *Backup OK" /tmp/log1.out
backupstat=$?
grep "^Termination: *Restore OK" /tmp/log2.out
restorestat=$?
\end{verbatim}
\normalsize

\subsection*{Adding Volumes to a Pool}
\index[general]{Adding Volumes to a Pool }
\index[general]{Pool!Adding Volumes to a }
\addcontentsline{toc}{subsection}{Adding Volumes to a Pool}

If you have used the {\bf 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 {\bf Bacula}
you will need to label it. 

Before adding a volume, you must know the following information: 

\begin{enumerate}
\item The name of the Pool (normally "Default")  
\item The Media Type as specified in the Storage Resource  in the Director's
   configuration file (e.g. "DLT8000")  
\item The number and names of the Volumes you wish to create. 
\end{enumerate}

For example, to add media to a Pool, you would issue the following commands to
the console program: 

\footnotesize
\begin{verbatim}
*add
Enter name of Pool to add Volumes to: Default
Enter the Media Type: DLT8000
Enter number of Media volumes to create. Max=1000: 10
Enter base volume name: Save
Enter the starting number: 1
10 Volumes created in pool Default
*
\end{verbatim}
\normalsize

To see what you have added, enter: 

\footnotesize
\begin{verbatim}
*list media pool=Default
+-------+----------+---------+---------+-------+------------------+
| MedId | VolumeNa | MediaTyp| VolStat | Bytes | LastWritten      |
+-------+----------+---------+---------+-------+------------------+
|    11 | Save0001 | DLT8000 | Append  |     0 | 0000-00-00 00:00 |
|    12 | Save0002 | DLT8000 | Append  |     0 | 0000-00-00 00:00 |
|    13 | Save0003 | DLT8000 | Append  |     0 | 0000-00-00 00:00 |
|    14 | Save0004 | DLT8000 | Append  |     0 | 0000-00-00 00:00 |
|    15 | Save0005 | DLT8000 | Append  |     0 | 0000-00-00 00:00 |
|    16 | Save0006 | DLT8000 | Append  |     0 | 0000-00-00 00:00 |
|    17 | Save0007 | DLT8000 | Append  |     0 | 0000-00-00 00:00 |
|    18 | Save0008 | DLT8000 | Append  |     0 | 0000-00-00 00:00 |
|    19 | Save0009 | DLT8000 | Append  |     0 | 0000-00-00 00:00 |
|    20 | Save0010 | DLT8000 | Append  |     0 | 0000-00-00 00:00 |
+-------+----------+---------+---------+-------+------------------+
*
\end{verbatim}
\normalsize

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.
