We use a Synology in Raid 5. 10 x 3TB hard drives. So far so good.

All actual data lives on each computer (a secondary data drive in EACH PC here). The Synology copies that drive from each computer at night. Also a external drive PER PC also copies that data drive as well. We have data 3 places per PC in other words.

That is an excellent way of doing it.I cringe anytime I hear someone say that 'raid is their backup'
That online backup I mentioned could have backed up your work in realtime... you might not have lost much if any with that running.Initial backup will be painfully slow.
As I mentioned in the other post, they Next Day FedEx you hard drives if you need.Also as I mentioned, this would be a LAST Line of Defense... if all other units fail, if your building burns down, you have something.Yes, it would take a few months to get that initial dump up there... but it starts with small files first and largest last... so a lot of what you do would be backed up pretty quickly.You would download any recent loses like you had on your recent failure.I guess, a better question is if your backups fail you (synology goes down and your external goes down) or your shop catches fire/floods, how fast can you get that other backup online now? First you have to have one. For this price... it's pretty cheap insurance that you never have to actually touch.
Haven't seen it mentioned, but I would look into some kind of offsite backup in addition to redundant drives. Space vs mobility vs u/d speed is always an issue, but I would at minimum have some kind of backup of the most important stuff off site in case of something like flood/fire/theft where just having redundant drives on site won't do squat. I have 3 waterproof/shockproof/dropproof/etc externals that I rotate and keep off site with my most important data and a backup offsite that I dump to from those periodically. Never needed it yet, but nice to know I have it. I don't mind losing a week or so of art, but losing it all would suck...
