I don't know of anything that does this, but I'm also not really sure
what the point is. I'd have thought that more useful would be a backup
taken every hour, say, so that you can easily revert human-error sorts
of problems. There's several tools for that sort of thing.

The life expectancy of SD cards is such that I'd expect it to fail long
before your (presumably) spinning-platters primary disk if you're
writing the same data to both, so it's not particularly good protection
against hardware failure, either, except insofar as the chance of one
of the SD cards failing at the same time as the primary disk is still
relatively low.
