Yup, at minimum you’d need another NAS off site (say, at a friend’s house) so you always have a copy. I have my NAS in a mirror to ensure I can recover if a drive fails, so that would mean 4x the cost of whatever storage size you need if you want to ensure your data stays safe.
Just some quick math, a WD Red Plus 10TB drive costs $190. So that’s $19/TB, and they have a 3-year warranty (used to be 5), so let’s assume they last 3-5 years. I need four drives minimum (two sets of mirrors), though if I have a lot of data and drives, that’ll go down (e.g. if I can use RAID 5 or RAID 6, I need less parity):
So $15-25/year, or $1.5-2/month, which comes with a few caveats:
There is a crossover point at which self-hosting is cheaper, but if you only need 1-4TB of storage, something like Backblaze is probably cheaper. But as you get bigger, the NAS looks more attractive.
