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
