Automatic image back up

[birdman]

you can do it via both first one is easiest.

Really?
Backups and Image backups are different things and should have different scheduling code, so why would the configuration for both end up in the same menu?
The code to cater for scheduling on boxes that may well be off at the scheduled time was added to the Image Manager sometime after it was added to the Backup Manager (when it occurred to me that that the same scenario obtained in both).
