provide a few ideas how to get out of these problem situations.

-\item [Problem]
- Your catalog has been damaged and Bacula either doesn't work or prints
- errors.
-\item[Solution]
For SQLite, use the vacuum command to try to fix the database. For either
MySQL or PostgreSQL, see the vendor's documentation. They have specific tools
that check and repair databases.

- A number of the items will be different in your case. What you want
- to do is: to use the mod option to change the Bootstrap to point to
- your saved bootstrap file; and to make sure all the other items
- such as Client, Storage, Catalog, and Where are correct. The
- FileSet is not used when you specify a bootstrap file.
- Once you have set all the correct values, run the Job and
- it will restore the backup of your database. You will then
- need to follow the instructions for your database type to
- recreate the database from the ASCII backup file.

- If you did save your database but did not make a bootstrap file, then

- is more difficult. You will probably need to use bextract to extract the
- backup copy.
- First you should locate the listing of the job report from the last catalog
- backup. It has important information that will allow you to quickly find
- your database file. For example, in the job report for the CatalogBackup
- shown below, the critical items are the Volume name(s), the Volume Session Id

+\item [Problem]
+ I try to restore the last known good full backup by specifying
+ item 3 on the restore menu then the JobId to restore. Bacula
+ then reports:
+
+\footnotesize
+\begin{verbatim}
+ 1 Job 0 Files
+\end{verbatim}
+\normalsize
+ and restores nothing.
+\item[Solution]
+ Most likely the File records were pruned from the database either due
+ to the File Retention period expiring or by explicitly purging the
+ Job. By using the "llist jobid=nn" command, you can obtain all the
+ important information about the job:
+\footnotesize
+\begin{verbatim}
+llist jobid=120
+ JobId: 120
+ Job: save.2005-12-05_18.27.33
+ Job.Name: save
+ PurgedFiles: 0
+ Type: B
+ Level: F
+ Job.ClientId: 1
+ Client.Name: Rufus
+ JobStatus: T
+ SchedTime: 2005-12-05 18:27:32
+ StartTime: 2005-12-05 18:27:35
+ EndTime: 2005-12-05 18:27:37
+ JobTDate: 1133803657
+ VolSessionId: 1
+ VolSessionTime: 1133803624
+ JobFiles: 236
+ JobErrors: 0
+ JobMissingFiles: 0
+ Job.PoolId: 4
+ Pool.Name: Full
+ Job.FileSetId: 1
+ FileSet.FileSet: BackupSet
+\end{verbatim}
+\normalsize
+
+ Then you can find the Volume(s) used by doing:
+\footnotesize
+\begin{verbatim}
+sql
+select VolumeName from JobMedia,Media where JobId=1 and JobMedia.MediaId=Media.MediaId;
+\end{verbatim}
+\normalsize
+ Finally, you can create a bootstrap file as described in the previous
+ problem above using this information.
+
+ If you are using Bacula version 1.38.0 or greater, when you select
+ item 3 from the menu and enter the JobId, it will ask you if
+ you would like to restore all the files in the job, and it will
+ collect the above information and write the bootstrap file for
+ you.

\item [Problem]
You don't have a bootstrap file, and you don't have the Job report for
the backup of your database, but you did backup the database, and you
How can I find where a file is stored.
\item[Solution]
Normally, it is not necessary, you just use the {\bf restore} command to
-restore the
- most recently saved version (menu option 5), or a version saved before a given
-date (menu
- option 8). If you know the JobId of the job in which it was saved, you can
-use menu
- option 3 to enter that JobId.
