What does the 3-2-1 rule look like for you? (lemm.ee)

I'm trying to plan a better backup solution for my home server. Right now I'm using Duplicati to back up my 3 external drives, but the backup is staying on-site and on the same kind of media as the original. So, what does your backup setup and workflow look like? Discs at a friend's house? Cloud backup at a commercial provider? Magnetic tape in an underground bunker?

Wow, a lot of variation in this thread!

I get all my data to my server, then from there I have borgmatic do incremental backups to a backup drive on the same machine (nightly cronjob).

From there I use Rclone to get the encrypted borg backup to Backblaze B2 for cloud storage.

So for 3 2 1, my 3 copies are the original, the local backup, and the cloud backup.

My 2 media are local hard drives and cloud storage (I think it's fair to consider this a different kind of media).

And my 1 offsite is the cloud backup.

Now I'm dumb and have a fear of screwing something up so I have also started burning M-Discs of my critical data (everything except TV/movie/music stuff I can redownload). Though this was a lot more expensive than I was expecting, because of aforementioned me being dumb I already screwed up two discs (they are write once). I'm also doing two copies of each disc.

Also I have photos/home videos additionally stored in ente, they are super important to me and I wanted a separated copy someone else is looking after.
