i'm gonna go Leopard next weekend and i want to back up my iPhoto library and keychain most of all. i know that keychain can sync with .mac, but how would i get it back after i install Leopard, i just sync with .mac and it downloads the whole keychain and all is well? does that work the same way with contacts and ical? what about my Mail accounts? i don't really care about deleting them, since every email is still up on the server and i'd just download them again, but it'd be nice if i could have the same state come back with just a .mac sync... with iPhoto, do i copy the iPhoto Library thingy to my external and then put it back to the same folder under Leopard?
