I worked with IBM several decades ago for a customer project, and the solution suggested by an IBM'er for backing up a NoSQL database (Lotus Notes) on a daily basis was to translate and migrate the data to a relational one (DB2), then use a DB2 tape backup system to back it up.
When I pointed out that this was a stupid way to do it, they openly told me that they just wanted to sell DB2.
