I've been informed on this list before that rdiff-backup has
shortcomings when used to transfer data over the internet and it is
better to use rsync over the internet and rdiff-backup locally on one
side of the other.  I did find out that rsync --fake-super will store
permissions and ownership in ACLs so that negates the need for remote

That's the next step.  I'm trying to lay the foundation first and then
add encryption and an offsite procedure.

If the clients rsync data to the backup server and the server runs
rdiff-backup locally on that rsynced data, and another system pulls
that rsynced data from the server and maintains its own rdiff-backup
repository, I think I should very likely be OK as far as corruption.
Offsite backups would negate the corruption threat completely I think.
 Does that sound right?
