Re: [Bacula-users] ZFS and Bacula

I have been using this setup for awhile. You absolutely must disable Bacula compression on the ZFS Devices within the SD or for the specific Pools that have volumes on the ZFS. Doubling up encryption can actually increase file sizes and also lead to data errors.

For 'normal' data, I usually get 30%+ compression with this, but for the data backed up with bacula, it didn't look that good, compression being down to 3-5%. Any idea what might cause this?
If the data coming from bacula are already compressed by the bacula-fd there's little space for improvement.
In your type of setup, I would disable compression on bacula-fd increasing the speed of backup, your sd doing it by zfs mechanism.
