Because the kernel buffers might not be flushed to disk, you may either want to
save/restore (instead of pause/unpause, and include RAM as part of backup) or
sync the disks from inside the VM before backing up.
Also, instead of straight rsync, check out rdiff-backup for incremental backups
based on rsync, I really like this program:
