OK.. Here's a thing.. I'm hoarder, I love having multiple backups of stuff and so on (yeah, still buying hard drives), but I found out that I have mess, like huge mess caused by fact, I store same files on multiple devices.. It's painfull especiallywin case of old book scans and pictures..
File listing isn't good one since it doesn't solve context.. I know there are multiple apps to do it, but.. AFAIK. Most require both copies to physically exist on drives connected to unit making comparsions..
So my question is, is there way to make database similar to md5checksums to make base of data about thousands of copies to let app (perfectly if it could be some Linux software) and then compare it with files on other storages?
I know I can do it manually, but.. Doing it again and again after finding new dipped backup is just painful ๐
