Probably best to gracefully shutdown PBS before copying the disk. Or do a copy (best effort, ignoring failures) first, then shutdown PBS and rsync all remaining differences to reduce the down time on the PBS.
Maybe someone more knowledgeable of PBS can tell us how to copy a Datastore to another disk?

If the Datastore is on a virtual disk, you could maybe use vzdump to backup that disk or even the whole VM to an external drive?
Or first backup the whole PBS VM to the NAS and then sync to external disk, much like you do now?
