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.
The restore of the same data to the same server was completed in 24
minutes. It's not network congestion during backup, as the backup runs
in the middle of the night, when no one is using it. It's all local LAN.
Any ideas of what could cause this issue? I've considered if it could be
due to the ZFS/deduplication load, but my logs/graphs show that the CPU
is not being overloaded (I use both Cacti and Zabbix to collect those).
Tks,
Roberto
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.
The client is a VM, running Ubuntu 24.04, Bacula 15.0.2, with 4 CPUS and
6GB RAM, 1TB storage.
