Yeah, I think in theory I would say everyone should get a consumer level NAS with redundant disks, plus SyncThing between devices for important small stuff, and some kind of cloud solution for offsite. But NASes are more than I want to spend and I've never used one, so I can't really suggest something I haven't tried. I just do manual incrementals to an external drive, plus of course GitHub for all software related stuff.
