I am looking for online backup for my 1TB of data (photographs and recordings) on external hard drives connected to my laptop, plus program files off the laptop. My partner uses Roxio for his desktop with exchangeable drives, but Roxio won't do external drives. Someone else suggested Ghost, but I do not understand the terminology used in any of the blurbs, and it all sounds far too much for my needs. Any suggestions? sensible pricing is also important!
