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 coreCPU
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.
Hello Roberto, Any chance you have disabled attribute spooling? ie: `SpoolAttributes = no` in a Job.This is the first thing that I can see which could inexplicably slow things down. If you are monitoring the MySQL server/service, have a look to those graphs during the Full backup run time.
