Hi all,
I've been trying to optimize the backup speed of my bacula
installation. My full backups, no spooling, max out at around 12-13MB/
s per client, where I think I should be seeing over 40MB/s. It
doesn't appear to affect the speed of per-client backups when more
than one client is running at a time. However, I've noticed that the
server's load average while in operation is always above 1, and
increases for each client it's backing up. So, if 3 clients are being
backed-up, I see load averages of above 3 on the server (though CPU
utilization is typically less than 50%). I'm not sure if this is
normal, or is in any way affecting the speed I'm seeing...
I should note that network bandwidth tests between the server and
clients typically reach full utilization (near 100MB/s) and the
drives on the clients and backup server are both capable of over 50MB/s.
Server-Side
Bacula version: 1.38.6 on Fedora Core 3
Backup Server: Dual AMD MP 1900 w/ 3GB RAM on a gigabit link, Adaptec
2940U2W SCSI
Tape library: ADIC Scalar 100 w/ three LTO-2 drives (using LTO-2 tapes)
Database: mysql, with indexes, running in a slightly modified 'huge'
config on the backup server
Client-Side
Bacula version: 1.38.5 on Fedora Core 3
Typical client: Pentium IV 2.4Ghz, 1GB RAM on a gig link
Thanks for any advice,
Ian
