I do this using rsync to give me 5 days of rotating VM backup. I don't use snapshotting or any other data-consistency measures, and I routinely restore the backups onto a test machine and have (probably luckily) not encountered any consistency issues a quick fsck won't fix up. As a double backup, I also use either Windows backup or rsync inside the virtual guests to perform full system backups.
