| Yup exactly just adding a suffix. I'm not only backing .jpg files. For example I also backup a few screenshots (some are in .png and some are in .webp format). So I don't care about the different pictures (or short family movies) format. I just wrote some Clojure / babashka code to do that. I also truncate the checksum so that the filename doesn't become gigantic: it's not sensitive content, it's just to detect corruption. Then I can use another computer and generate, say, all the thumbnails of the pictures and do a quick eyeball verification. If it looks correct, later on I can just automatically have the checksums verified. Funnily enough I got a few old JPG pictures who were corrupt but I ended finding the correct version on older backups. Checksum then helps too: otherwise you have two files with the same name (say on different HDD), but only one is correct and you don't know which one without manually opening them. It's not super advanced and maybe a bit overkill but it's not complicated and works fine for my use case. P.S: I take it another way would be to use a fs that use content-based addressing or does checksumming for me. |
