OmniBack 3.1 - HP-UX and Linux

[Aaron Mahler_1]

Hello!

Has anyone used HP-UX 11 on the 9000, OmniBack, and Linux together? The
ability to back up the Linux boxes is not critical for us, but in my
experiments I've gotten horrible performance. The HP box is backing up
perfectly. The Linux box I've tested seems to interact just fine until the
backup begins. I was testing a ~650 MB backup this morning that started around
10 AM - at 1:30 PM I aborted it after completing only 115 MB. No errors, no
warnings... just horribly slow.

The Linux box is running RedHat 6.1 and speaks to the HP-UX box via switched
100 MB Ethernet. Outside of this application, performance is superb between the
two systems.

I realize the Linux client is unsupported, but figured I'd ask anyway. :)

Thanks!

I just tested my setup here. ~3gb in 25 minutes.

Cell server: E25
media server: N4000 w/ FibreChannel DLT array
disk server: SuSE 6.3, dual PPro 200mHz (IDE drives, unfortunately)
network: 100mbps switched

There's a whole lot of things that may cause your backup to be slow. If you're
network isn't saturated, check your Linux drive system.
