I've seen somewhere script that does the following. It dumps all
databases, then commits them into some version control system. CVS and
subversion come to my mind. As the last do diff of text files 9and this
way keep changes from version to version), and database dump is ASCII
text, this will fulfill pretty well what you need. I must confess, I never
came to the point of setting it that way myself: with database sizes we
have, and the space we can devote we can handle a week worth of daily full
dumps, and a couple of Months of backups of these... but one day I'll do
it this way. The following may not be what I originally saw, but seems to
be doing exactly this:
