Subject: [Bacula-users] Issue with Bacula Virtual Full backups.

Hi All,

          Just joined the mailing list. Was hopefully looking for a bit of support/advise on an issue were having with my version of bacula. We are currently running version 5.0.1 of bacula on an Ubuntu 10.04.4. 99% of our servers are being backed up just fine. There is an issue with our mail file server. We use virtual full backups for our file server as they are so large to backup.

Because the Virtual Full Backups bacula takes the last Full backup and all the incremental and full backups since then to create the new virtual full. We have 2 media pools, so bacula will read from one and write to the other when it create its virtual fulls. We had an issue with our last virtual full this month and as you can see from the output below the virtual full for July is using pool-2 so augusts backup when I run it should be saved in pool-1. However it’s not.

When I run the command     ‘run job=Filesrv1-Job level=VirtualFull pool=Filesrv1-Full-Pool’   to tell bacula save your job to pool one it doesn’t. It saves the job to pool-2. This is going to be an issue when next month backups run as bacula will try and read from and write to the same pool (I think).

Hello Anthony: I have almost no experience with VirtualFull backups, but I think it is pretty similar to the the Copy jobs. You must set a pool+storage (normally in Pool resource) of origin, and a pool+storage of destination.
Bottom line: if your configuration is correct it would never will read from a backup in another pool.
Btw: version 7.0 allows you to use the same pool for this kind of operation: 
  • You are now allowed to Migrate, Copy, and Virtual Full to read and write to the same Pool. The Storage daemon ensures that you do not read and write to the same Volume.
