Re: Crashplan did it all...
The well-known ones like Backblaze, SpiderOak, Carbonite all tend to be OK for a single computer, but get very expensive backing up multiple machines (e.g. for a family).
Years ago I had Carbonite, but they started trottle if you had more than 100GB, When I switched to crashplan it only took me 2 days to sync my 200GB. My only complain with Crashplan is that often my storage pool has not been online when I needed to restore a file. I had to wait up to an hour.
