Thanks! Is file size a necessary part of the check, or can mod time
alone cover it?
I'm looking at having my monitoring application automatically bring
database nodes up, so it looks like the simplest way to handle it will
be to have the new slave mandatorially do the backup/rsync, even if
it's been down for only a couple of minutes. With a mod time check, I
could hopefully do this without too much hassle.
