Lots of info requests, I know, but I really appreciate the help. My ISP and
all the experts I've tapped are completely stumped on this one.

In an admittedly non-backuppc environment I've been
experimenting with using 'rsync -W' (this means
don't use the rsync algorithm) to see if
problems similar to the ones you describe go away.
I'm still not sure of the result.

How often do you want to backup the server? What about using

Well, backing it up once a day would be ok for me

Hi,
there is a regular discussion on how to backup/move/copy the backuppc

I need to expand the raid volume where the pool is stored (Arecac RAID
controller). Doing this without backup is a bit frightening (I didn't
use LVM for the filesystem).
