I try to throw lots of photos to FB for the reason that I have a 3rd place (and Insta).
I think I'll try BackBlaze, though other than photos /video, most things are in Dropbox/Evernote/Github/VSTS, so I don't worry about the physical machines here. I guess some sync of corrupted files would be bad.
Amazon Glacier is tempting as a long term cold backup. Anyone tried Cloudberry software to easily manage things?
I'm in the same situation as you with Crash Plan. Let us know how you like BackBlaze.
