For the "cheap" part one'll probably need a system that has erasure coding and can survive partial outages.
E.g. if one backs up to hubiC, OneDrive and Google Drive, with a RAID5-like redundancy, they can have just 33% overhead and still be sure shall any of those vendors discontinue the service or suffer a failure, their data would be still safe. Some call that RAIC - Redundant Array of Inexpensive Clouds.
git-annex and Tahoe-LAFS do this, but they're not actual backup solutions.
