Most of them get backuped daily or weekly. Right now /var mixes : 1. data that can be safely lost/erased at any time (caches) 2. data that the admin should work a little harder to protect (for example, it should never be erased on reboot) but is transient by nature. For example mail/print spools. It's pretty useless to backup them because their state is almost certain to have changed by the time the system has crashed, and if your restore the nightly/weekly backup you'll probably only re-queue data that was already moved somewhere else 3. long-term data. That's what people move to /srv or a separate root - it absolutely requires specific backup policies, and because it's served from this particular system you won't find it anywhere else in case of problem -- Nicolas Mailhot
