If you set your NAS with RAID 1/5/6 and have some unused spare disks at hand, then you shouldn't have to worry about backing things up since when one disk fails (two with RAID 6) you can replace it with the spare disk without losing your data.
Strictly speaking no RAID configuration, no matter how safe, can be considered a backup. What if 2 drives fail in a RAID 5 config? Or like that many other cases.
When I mentioned "Backup" , I meant an identical bit by bit copy of your entire NAS to an external location, sort of like when you clone a hard disk to another physical drive.
