Hi

I am doing something similar.

local machine rdiff-backup to /backup (lvm partition).
then a rsync to the local backup server and at the same time a rsync to
an offsite location - via adsl.

I do this because my initial rdiff-backup can happen quickly and cause
the lest disruption - if the source is on a lvm I can take a snapshot
and use that but not all the sources are.

I have come across one problem, if the over adsl takes too long the
rdiff-backup destination on the local machine can change thus giving you
a non in sync backup offsite.

There is another thread asking for a tool to lock the destination to
prevent this
