I was hoping this could be clarified for me-
I just 'cleaned' up my internal hard drive because all my raw file pictures were filling up the memory- so now I've moved them to my external hard drive, and only kept the most recent photo raw's on my computer.
My question is- when I plug the hard drive in to back up again- will it back up and take off everything that isn't on my computer now from the external hard drive? Or does it only 'add' to the external hard drive?
Just to clarify- I have RAW files on my external hard drive that are no longer on my computer- when I back up my computer again, is the external going to get rid of everything that's not on my computer now? Because I still want those old files on the external hard drive.
Sorry if this is a dumb question- I'm new to this whole 'backing up' thing.
Thanks in advance!
