Hi! So I have an external HDD with a large number of important files that use about 200Gb of space. A few months ago I manually backed up the data to different computers throughout my house. I continuously add and remove files to this HDD and I don't update the other backups.

This creates a problem because the changes are numerous and it would take hours to update every backup manually.

So what I'm looking for is software that will compare the relative names and locations of each file and delete or add files accordingly untill both backups are similar.

What I've tried:

* Use the 'tree' command and then use a text comparison tool. This is ineffective because one deleted file will cause every following line to not be a match.

Thanks for any information you can provide.

Edit: if necessary I'm willing to re-create this backups using software that can then check for differences.
