Hi all, Quick question: I have an external drive with all my work-related files. Call it ‘disc A’. I have a second external drive, to backup that fist one. Let’s call it ‘disc B’. I usually tag the new files on disc A so when I connect my backup drive B, I can select those and copy them (manually) to drive B. But… I was wondering if there isn’t a little app somewhere in which I can say: Drive A is my master drive, Drive B is a slave-drive, and let this app scan both and match the files from Drive A to Drive B. So that I never overlook something. I hope I’m getting this across Does anyone know such an app? Doing it manually in Finder by dragging the new files and folder from A to B every week seems very archaic. Any tips or insights would be very welcome!
