Hello,

we have a rather large Bacula setup - ~600 Clients, database for catalog is 19GB large. File table is ~65 million records.

Right now, bacula director can not run backups as scheduled and delays the jobs for up to 2 hours, as it seems the catalog is not keeping up.

CPU usage on SD is: 25% (0,5 Core)

CPU usage on Dir is: 10% (0,2 Core)

CPU usage on Catalog is: 25% (1 Core)

SD has not hit it’s storage IO limit, as I/O Wait is almost zero (24x 10k spindles in Hardware Raid, doing ~50MB/s avg).

Also we have defined 20 parallel backup drives doing backups, so drives is not a blocker I guess.

It seems that the bacula catalog is CPU bound and that only a single core is used (of 4).

How can I parallelize database access with Bacula Director to speed up the backup process.

Regards,

Robert
