Introduction

The following script was written to provide a quick way to run a backup of the Request Tracker mysql database. This is a good tool for routine daily backups and can be run as part of the daily cron batch.

Requirements

I wrote this for Debain Sarge/Stable and it depends on having the exim4 mailer installed. I also requires that there is a ''tmp'' dir in /root. It also assumes that ''root'' (or what ever account the cron job will run as) will have DB access rights to the RT Database.

Caveat Emptor

This script is provided with no warranties expressed or implied. Use your own risk. Milage may vary.

TODO

  • Add section to detect mailer and automatically set this envvar
  • Add automatic tmpfile cleanup
