I’m looking for alternatives to CrashPlan. Using them to back up 9 computers (3-4 TB) Mac/Win/Lin, but after they cancelled their 4 year plans and doubled prices now’s a good time to look elsewhere.

How do Black Blaze/ Mozy stack up these days? Are there other players that I should consider? I do not want to bother with rsync and S3 again, and prefers something that’s been around for a while and will be for the foreseeable future.

Needs to be in the cloud, encrypted, handle extended attributes on OS X, and work on Mac/Windows/Linux. Preferably unlimited storage + history and a large allotment of computers (I’ve another 10 computers I’d like to add to the backup).
