As for Acronis, it works well from a NAS.  But if you need to do a "bare metal" restore (hard drive replaced), it's a lot easier if you copy the backup to a USB drive and restore from that.

I don't recall any difficulty running over the network (booting up with the restore image).  But I was using gigabit ethernet.  If I'd been using WiFi I probably would have copied it to a USB drive.

Yes, RAID protects you from most hard drive failures (not from those so severe it otherwise damages the NAS, which is rare).  It does not protect you from other faults in the NAS, fire, flood, theft, etc.  Since NAS hardware can change, and the file system with it, relying on being able to buy replacement hardware in the future in case the chassis dies is not the best plan.

If you are only storing image backups on the NAS, then RAID might well be enough.  After all, you still do have two copies on different devices (the original on a PC and the backup on the NAS).

Unfortunately some of the marketing out there might lead you to think otherwise, but if you use the NAS for primary storage, then you will do need a backup
