rsync'ing the BackupPC data pool is generally recommended against. The
number of hardlinks causes an explosive growth in memory consumption by
rsync and while you may be able to get away with it if you have 20GB of
data (depending on how much memory you have); you will likely run out of
memory when your amount of data gets larger.

future versions of backuppc may deal with this problem better.

There are ways of replicating the backuppc data pool remotely; but I have
not tried them myself.
