That's the way it should be.

The difference with my dozen or so Pi's is I do the incremental backup
to the NAS, not directly onto its filing system, but into an image file
which was created from the Pi's SD card. This means that if any of the
Pi's SD cards fail, I can just get a card of the same size and write the
image file straight back on to it, and be up and running again in minutes.
