should be able to generate dumps throughout the day, generate a diff from my
baseline dump, and just keep the diff, right?  Then to do a restore I would
just patch for the point in time I wanted to restore to?  Seems like it would
work, but whether it would save any hard drive space would depend on how much
activity the database saw.  Anyone doing this now?

idea is god, but dont use suggested diff program. go for xdelta. it's
algorithm is much better - faster and definetly less memory-eating.
