I've only two backups for the photos, but I do alternate them. That's the only weakness I can spot in your system - if you mess up the desktop HDD, the other day the mess will be replicated 4 times. Else than that, I cannot imagine any serious worst case for your system.

I use rsync to mirror my desktop every night. So if that were the only "backup" system I had in place, yes I would be screwed.

However, the NAS performs incremental backups every 3 days and the online backup system runs once a day (and keep a 1 year history).


Consequently, even in the event I were to totally mess up my system and screw up everything, I'd loose at most 1 day of data.
