Actually I would be fine with anything under /usr being wiped three times a day over /var being wiped even once because /var is where all our important data lives (between /var/www, /var/lib/mysql and /var/lib/postgresql among others). /usr is the easily restorable distro stuff, /var is the unique data.

See my discussion with nim-nim above. /var is a mess of intermittent data (caches, logs, spool) and important data (as you mention). From an application perspective it is perfectly ok to wipe both, but the user will moan about the data. The idea is to be able to clone systems by forking /usr and providing an empty /var. Or doing factory resets (i.e., remove all user data) by wiping /var.
