Hello,

Thanks to a patch published two weeks ago I am finally making headway
into the wonderful world of Bacula. I have a single machine right now
with about 1.2T of data I am backing up.

When I run the btape fill test I get write speeds of around 70MB/s when
I run a full backup from the local machine I get about 20MB/s is there
anyway to figure out where the bottle neck is?

The storage in the machine is a 3ware SATA 9690SA card with eight 1TB
drives in a raid6 configuration. The tape drive I have is a Dell TL2000
connected via 4gig qlogic fiber channel card. I am running Ubuntu
8.04.2LTS.
 
Thanks
-H
