Old time machine backups
I've just stumbled across an old hard drive that contains some old backups of my computer (5 years ago). I had since moved my backup drive to another disk.
I'm just wondering what to do with it - is it possible to merge time machine archives to create one long history? (Just in case I deleted something from my archive 6 years ago)
Or will that corrupt my current time machine?
