You mean hardware snapshot? I know taking a backup using rsync(or tar, cp?) as a
n online backup method is not so a big problem as documented. But it just take a
long time if we handle a terabyte database. We have to VACUUM and other batch
processes to the large database as well, so we don't want to take a long time
to take a backup...
