Re: [Bacula-users] deduplication within a volmue

For the bacula volumes it's not very high. It's in mostly in place to handle hundreds of thousands of wav files whose first 20-30% is the exact same content. To control the size of my bacula volumes I instead employee a very aggressive recycling policy on the pools.

Have you looked at your dedup ratio? Because other have reported it to be very low, because of the Bacula's volume format.
