since the cpool will need rebuilt anyway, why even transfer it? the problem
with transfering the cpool with rsync is that you MUST transfer the entire
/var/lib/backuppc directory so that all the hardlinks may be resolved, you
might as well NOT transfer the cpool/pool and rebuild it on the other end.
the decommissioned hosts will still have files in the pc directory and the
nightly run only deletes single-linked files from the pool directories.
assuming you have the host in question setup in the config and have backups
turned off and have ample time in the keep full backups, then everything
should be fine.
