Greetings!
First, I apologize if this comes through multiple times. I'm having
trouble connecting to the list.
I've been trying to bake off AMANDA and Bacula in our environment, and
have run up against a Bacula performance snag. Amanda is regularly able
to average ~50 MB/s over our network, while I'm getting ~30 MB/s out of
Bacula (spooling turned on over gig-e). I like the feature set and usability
of
Bacula much better than that which AMANDA provides, but the speed
difference is an issue. I think the difference may have to do with
AMANDA running multiple simultaneous dumpers on the client. I've bumped
"Maximum Network Buffer Size" to 65536 bytes in both the storage daemon
and file daemon configurations with little to no change from the 32K buffer.
A typical Bacula client status reads:
*status client=foo-fd

Any ideas what I can do to eek out some more speed?
