Favourite? Probably Kavita.

I’m looking to sell Forgejo next myself

For my buddy and I our critical data doesn’t change often so once or twice a year when we get together we swap drives again. Simple spinning discs for us. No need for hardware or anything to keep them running. They just sit on a shelf just in case something happens we can hand it back to pull the data back onto a running server

My friend who lives a thousand miles away swaps hard drives with me that are backups of critical stuff. He keeps my data, I keep his. As others have said your garage is a start but you really want some sort of geographically separate backup.
