Right now I’m creating a nightly restic snapshot of my server on borgbase and on some spare drives, and keeping the snapshots forever. There’s a ton of daily churn in my data though, between databases and logs and other files that don’t constitute ‘real data’ but might be needed to restore the app.
I have Nextcloud on my server which stores all those documents and photos etc. I have nightly offsite backup as well as backing up to a local borg repo on a separate drive.
But as it’s that important to me, I also do a once-yearly backup of non-encrypted files to M-Disc, with two copies, one stored at my mother’s house. This way if my house burns down and I’m inside it, my family can still get (most of) the precious memories without needing to know how to access a borg repo and without having to know how to download from Backblaze object storage.
I’m just a little bit paranoid about losing things after that one time I dragged from a USB stick to my computer and when it was done moving the files they were all corrupt, and didn’t exist on the USB stick anymore either. Thanks Windows, a whole holiday of photos gone.
