One thing to consider: you could omit the syncing of pool/ and cpool/ when
rsyncing to remote if you are rsyncing for disaster recovery purposes only. 
This will save some memory/time.  Note however that rsyncing the BackupPC tree
will likely be less efficient than just an rsync directly, because it won't be
able to use binary deltas during transfer since it will appear to rsync as if
the files are new since they have new names.
