*2 different types of media. But having an offsite copy is more important; this part of the rule is mostly just about avoiding failures due to stuff hard drives in the same batch failing at the same time. Or a tape drive that has gone bad and destroys tapes when you insert them, because if that’s the only format you have you’re SOL. If you have another copy on CD then you can use those.

Don’t confuse backups with syncing. Although syncthing has a recycle bin to recover deleted and overwritten files, you shouldn’t rely on it for guarding against accidental deletion, file corruption, or ransomware. You want something that will allow you to restore files from a point in time. There’s lots of proper backup tools for this. Borg, Restic, etc. Each has pros and cons. Make sure you test recovery. Also 3-2-1 is 3 copies of data, on at least 2 different systems, and 1 off site.

Syncthing has multiple file versioning strategies.

So it can provide quite solid protection beyond a trash can, but yes, it’s still primarily a syncing tool.
