DuraCloud

DuraCloud is an open-source software that facilitates storage of electronic archives and other data on multiple cloud platforms at the same time. The initial announcement for the product is here: []

The announcement for the most recent version of the product is here: DuraCloud is sold by DuraSpace, which also produces software for creating and managing institutional repositories. A basic subscription to DuraCloud (with 2 redundant copies of data stored by a single cloud provider) costs $1,500 per year. This might be beyond the needs (and means) of the small public library we're picturing, but it's worth thinking about.
