I wouldn't really do it that way. The reason being, running
applications like a database server, might have unflushed data, i.e.
the on-disk data structures would not be fully consistent. I don't
really like taking a backup in that state (called crash consistent
state). If "possible" it's always safer to power off before
snapshotting, otherwise, at least make sure your applications have
flushed all data to disk (mysql can flush and lock tables to do
that, but other apps behave differently)<br>
