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.
As I commented to the answer from Bill Arlofsk, I did not have specific
monitoring for MySQL. I implemented it now, but have to wait a few
backups to run to have some data.
BTW: OpenZFS 2.3.0 was just released and significantly improves dedup
performance.
That's something I will have to look into in the future. Tks.
