Hello,
I think I have come across a bug that exists in bacula-2.2.8, and is still in
svn trunk, as I have tried the same scenario with both.
I have three machines.
On the first (tdir), I have:
a bacula-dir
a bacula-sd (Disk 1)
a bacula-fd (with a few mebabytes of data to be backed up)
On the second (tsd), I have:
a bacula-sd (rDisk for tdir)
On the third (robertxp), I have
a bacula-fd (with a few gigabytes of data to be backed up)
I configure tdir to run two jobs:
1) backup robertxp to the storage daemon on tsd.
2) backup tdir to the storage daemon on tdir.
I tell it to begin (1), which will take a long time, and observe the data
arriving on tsd (rDisk for tdir), in a file called 'backup-0001'.
While that is still running, I tell it to begin (2), and observe the job
running and complete successfully on tdir (Disk 1).
I look back in the log, and I find that it has marked 'backup-0001' as Purged,
but the first job is actually still running! I can watch the size of the file
increasing.
>From this point onwards, what is in my catalog doesn't reflect reality and
unexpected things happen.
Here is the log produced via the above scenario:
