Well, first while raid is great, it’s not a replacement for backups. Raid is mostly useful if uptime is imperative, but does not protect against user errors, software errors, fs corruption, ransomware or a power surge killing the entire array.

Since uptime isn’t an issue on my home nas, instead of parity I simply have cold backups which (supposedly) I plug in from time to time to scrub the filesystems.

If a online drive dies I can simply restore it from backup and accept the downtime. For my anime I have simply one single backup, but or my most important files I have 2 backups just in case one fails. (Unfornately both onsite)

On the other hand, for a client of mine’s server where uptime is imperative, in addiction to raid I have 2 automatic daily backups (which ideally one should be offsite but isn’t, at least they are in different floors of the same building).

The point is that 8TB are too small, and not enough for my anime.
