Athens backups

Athens, being or main server, should be backed up, or at least the important files should.

Overview
There are three main areas of the backup


 * 1) What to backup (how much data?)
 * 2) Method of backup (scripts, a tool, many generations, just one?)
 * 3) Location of backup (another local hard drive, remote host, DVD?)

Important data to back up
Step one is to identify important things that should be backed up.


 * DNS (BIND) config
 * User home directories (includes email)
 * Websites
 * MySQL (much website data, including this wiki)
 * /etc, which is all config files

Method
Step two is to devise a method, modifiable, for actually doing the data copies.

Backup location
Step three: where should the backup be stored? Maybe more than one place.

Options include:
 * Second hard drive on celery (celery has at least two drives, i think)
 * Remote host hard drive. Could be: darkstar, thecidatel, quasar, or maybe even nero.
 * DVD or CD. Would be done in two steps, ex: copy data to darkstar, burn to DVD on silverstar, manually by reaper. DVD stores 4,700,000,000 bytes, or 4.38 GiB. Probably not good enough for home dirs, which will be v. large.
