The best way is to just backup to multiple locations and actively manage it. RAID at the backup destination is nice because it means that if a disk fails, you don’t immediately lose everything there. But if you have multiple places where that data lives then it’s not the end of the world to just re-create the backup.
If you want to get into true archival solutions(way more expensive than setting up a RAID) then you’re looking at things like M-Disc and LTO tape
I went M-Disc. Need a special burner and disks cost me $30NZD each or about $18USD for 100GB.
They are write once (I fucked up two early on) but they should last 100+ years. I burnt about 1TB, and made two copies (one for offsite storage). It was not cheap.
What’s a good medium to back up to, assuming I don’t want to pay for a RAID setup?
RAID is not a backup.
To be fair, RAID is not backup for itself but if they have their stuff on a computer and then sync it to a NAS RAID then that’s backup.
Yeah, the idea is that you should have another copy that is disconnected from the main one, if you have that then you do have a backup.
