the main problem with this, is that one client on that VM (think about
shared hosting accounts on the VM) wants to restore a single file, or a few
files, then you're going to have to restore the whole snapshot and a lot of
other files will be lost.

I'm experimenting with an NFS mount from our backup server. Basically,
export the NFS share, and mount it inside the VM, then use
your favorite backup procedure / software. For our cPanel VM's, we use
cPanel's native backup function which makes use of rsync - and allows us to
restore a single file if needed. For other VM's without a control panel,
rsync also works well.
