I couldn't find any info on backlift, which was acquired by squarespace. I'd comment that we're going for a toolkit to build sites, were as squarespace gives you a canned set of features, with our service you can build almost anything you can imagine. Something similar would be syncano, were they seem to be nosql, we are sql.

Data backup besides our periodic update (we haven't finalized the frequency, hourly for example) is through an api to pull a snapshot. Otherwise, we're considering backing up the database to a user provided S3 bucket.
