I am considering an online back up storage for my photos an for the most important files on my computer in general. A lot of these services - dropbox/googledrive - are pretty expensive. I do however, see that crashplan+ offers a service that is unlimited for one computer at around US$5 a month. I am looking at about 250GB of storage rising to 1TB over a 3 year view. I just wondered if anyone had used either this service or something similar and what they thought about them.
