If you don't expect to restore, but just want a copy for safekeeping,
use the archive host feature or BackupPC_tarCreate to make a standard
tar archive that can be kept independently from backuppc. If you
want the data to be pooled with other backups, at this point the best
you can do is restore (perhaps one at a time) to somewhere with
sufficient disk space, then let the other server back it up.

The usual approach is to image-copy the partition or drive holding the
data, then optionally resize the filesystem on the new server.
BackupPC_tarPCCopy expects the pool/cpool directory to be copied first
with rsync and exactly in sync first (and should be documented as
such. You can't do that after making other backups on the new
server. You can simply 'rsync -aH ' the host directories under pc to
the corresponding new location and everything will work. However,
those files will not be pooled with other hosts.
