I run it on TrueNAS Scale. Yes it is all quite fragile, but I managed to get it in a state where it works if I don't touch it. It's all backed on a ZFS volume. Barring significant hardware failures I will be able to access my data locally. I use Storj for mirror remote. Rebuilding would be a bit of a pain, but I have reached the E2EE personal cloud ideal. If [better than storj] cloud storage services offered BYOPK E2EE then I wouldn't need to jump through such hurdles.
