i like to use rsync to replicate running servers.  of course, for
one-shot copy it's no faster than other dump-transfer-restore schemas;
but it's quite easy to use to quickly converge almost to a 'snapshot'

1: do a full rsync, might take tooo long, lots of stuff wouldn't be
really consistent
2: repeat rsync, should be far faster, copying only the differences.
3: keep repeating until the whole copy is comfortably short. usually
the third iteration is less than a couple minutes
4: quick: shut down services, one last rsync, start services.
5: done!
