I suppose I couldn't guarantee I haven't, but I keep a total backup, and other backups based on file lists. I keep a record of every file of importance that I've ever written/modified/interacted with, and those lists themselves are also git managed.

I compulsively look at the rsync backup running to see what's going to transfer, and typically do a dry-run first. That's no perfect solution, but it works for me. If I see something odd I don't quite remember, I check the hashes between both drives, and every time it turns out it was just a path change since I try to keep my data as organized as possible.

rsync arguments are just the plain `--archive --acls --xattrs --verbose` and depending on which backup I'm doing, `--recursive`, `--delete`, `--files-from=`. Nothing other than vanilla at all.
