Hallo,
I found a typo in a Job resource that has been backed up for a
couple of weeks, so I wanted to rename it. Here are the steps I took. I
hope it will be useful to somebody else.
Bacula gurus feel free to burn me if this is heresy :-)

Let's call the job Mailserver and suppose the misspelled name is
Malserver (missing 'i').
The database server is postgresql.
- stop bacula-director to avoid catalog modifications while we are
working on it;
- backup the catalog (e.g. with mysql or postgresql dump tools), just in
case;
- rename the job in the bacula-dir config file;
- connect to bacula database directly via db console (psql in my case)
The table we'll work on is named "job".
The columns that we have to modify are "job" and "name".
The jobhist table should also be checked: if it has records, the
procedure should be applied there too.
- count the number of records to be modified (just to check the update
command)
bacula=# SELECT COUNT(*) FROM job WHERE name='Malserver';
bacula=# SELECT COUNT(*) FROM job WHERE job LIKE 'Malserver%';
You should get the same number of records.
- update the name column
bacula=# UPDATE job SET name='Mailserver' WHERE name='Malserver';
- update the job column
bacula=# UPDATE job SET job=replace(job, 'Malserver', 'Mailserver')
WHERE job LIKE 'Malserver%';
The two update commands should modify the same number of rows counted
before.
- Check the jobhist row count and apply the rename procedure if it's not
zero.
- restart the director
The misspelled job name will remain unchanged in the "terminated jobs"
section of the status command, both on the director and on the client
nodes (*-fd). That's because that information is stored into status
files and not into the database.
- Test table
Before applying the update commands to the actual catalog, I tested them
on a temporary table. To create and populate it with the actual records,
I used the following commands:
bacula=# CREATE TABLE test_rename(jobid integer, job text, name text);
bacula=# INSERT INTO test_rename(jobid, job, name) SELECT jobid, job,
name FROM job;
Obviously a DROP TABLE test should be issued at the end of the rename
procedure.
