Except for the first of the month, the diff of that nights backup

in the database would likely mean I have to change my backup protocol,
but if it really is advantageous, I'd do it.

This is just an aside but are you aware of the '--hex-blob' argument to
mysqldump? It causes binary data to be dumped as a hexadecimal string:

It's space-greedy (every byte in your original data requires two bytes in the
dump file) but it seems like it would be compatible with your mysqldump/diff


No I wasn't aware of it.
I'll keep it in mind if I ever do start keeping binary blobs.
