Hy,
I'm having a performance issue with my installation.
When I make a backup, to backup is running well bellow of the expected
speed. A restore, on the other side, works fine.
In one example, I made a (full) backup of one server. The full backup of
137.7GB took 4h 25m.
My setup:
Server running Ubuntu 22.04, Bacula 15.0.2, backup is in a local RAID
array set as ZFS with compression and deduplication, with a quad core
CPU and 8GB RAM. Bacula is using MySQL as backend.
Have you benchmarked your MySQL configurations's performance and tuned
it properly for the workload? Fast restore, slow backup COULD be a side
effect of an underperforming catalog DB.
BTW: OpenZFS 2.3.0 was just released and significantly improves dedup
performance.
