[Bacula-users] backing up to disk

Hello,

I am backing up to disk and I am having some issues with a particular pool. Mail-diff-pool:

Pool {

Name = MailPool-Diff-tape

Pool Type = Backup

Recycle = yes

AutoPrune = yes

Volume Retention = 1 months

Maximum Volume Jobs = 1

Label Format = "H22-Diff-"

Maximum Volumes = 3

Storage = H23-FileStore-diff

}

The idea is to do a differential backup every weekend where the full backup doesn’t run, this should be 3 weekends. Each of those weekends should use 1 tape.

The problem I am having is that it seems like the first time the differential backup ran, it created file sizes (for the vtapes) of 4.2GB, 4.8GB and 22GB. Now that the differential backup is to run again, it used ALL 3 vtapes for 1 job. In the job log I can see each tapes being purged and recycled in order to be used, but then it just stops once it fills up the last tape.

Are the file based backups supposed to increase and decrease the file size for the vtape depending on what’s used for a particular run or once the file size is set there is no resize for them??

Thanks for any info.
