Comment on What do people use for a shelf-stable backup
Dave@lemmy.nz 3 weeks agoI have automated backups including to cloud, but I want a separated manual system that cannot get erased if I mess something up (accidentally sync a delete, lose encryption key, forget to pay cloud bill). I have 3 2 1 but it’s all automated and backups are eventually replaced, if it’s not a critical failure I won’t necessarily know I’ve lost something.
Basically, I specifically want cold storage, and not cloud. I will only add, not delete from it. And I don’t want it encrypted.
Based on other conversations I’m planning on using duel disks mirrored, zfs, annual updates and disk checks with disks rotated out every 5 years (unless failing/failed). Handling the need for layman retrival of data by including instructions with the hard drives.

I have a client with a photographic studio. To give you an estimate, his data is around 14TB of mostly camera pictures with approximately 20 years or history and the owner believe it or not, relies on multiple external hard drives for cold storage, he has a 2TB Seagate thats like 2011-2012 old which still works.

That sounds like a really good idea. You basically get the best of everything.
The cool thing about ZFS is the pool information is stored on the disks themselves. You can just plug them in and import the pools.
