Well, I've become very fond of rbme as of lately, but since ReaR supports
rsync out of the box, you don't need a separate backup method for it.
But if backuppc has a client, or a configuration, it's very easy to make
ReaR aware of it. And then to only configuration you would need to do is:
BACKUP=BACKUPPC
and it would automatically create a bootable image with your system's
layout and the backuppc software/configuration, and even the necessary
commands to automatically recover your system when doing:
rear recover
on the rescue prompt. That's how it is done with Bacula, TSM, and others.

Does backuppc take care of restoring HWRAID, SWRAID, DRBD, LVM, paritions,
filesystems ? If so, then ReaR may not be for you, because ReaR takes care
of those items.

Definitely, join the list and we can help you implement it.
