Also, I'd like to pay for a backup tool, since it's so critical, so that I can get a sort of support, but I have found issues with many of them. I must say that, with my small population (N=1) for testing, it was hard for me to settle on a backup system. I tried duplicity, then I tried borg, then I used duplicati. I had considered attic and restic as well, but I don't remember why I didn't choose them right now. I experienced issues with most of them and I reverted to duplicity. With borg, I had a persistent issues where backups would stop and said something like "backup destination is newer than source" (I forgot the exact message, but happened multiple times across versions). Duplicati seemed a very large and complex codebase, and periodically stopped working, mostly because dotnet runtime issues AFAICR.
