Media I don’t take as seriously as other backups. Except for a few hard to find ISO’s, I have a Fractal R5 case that I’ve crammed full of all the rando extra drives I have sitting round, and pool those all together in TrueNAS. So far it’s more than the total storage of my media NAS. It gets a monthly backup automatically.

I don’t nas, but I suggest a combination of offline drives, cloud services or remote hosts, and just ignoring data that is easy to recreate like builds and software installs.

The key is to keep the data organized in such a way that you know which parts deserve which strategy.

I use an rsync bash script and a 1TB SSD. I keep media unencrypted, and use Veracrypt containers for any sensitive data I need to back up.
