Metacat

#!/bin/sh

#

# Backup files needed for metacat.  This script creates a temporary directory,

# backs up the postgres database, metacat data files, and ldap directory, and

# then creates a gzipped tar file from those files.  It then writes the backup

# file to a DVD drive and then cleans up any old backup files.

#

# To run this file, install it in /usr/sbin or a similar location and add an

# entry in the root user's crontab to run the command periodically.  The

# following crontab entry would run it every night at 2:00 am

# 0 2 * * *       /usr/sbin/backup-metacat.sh >> $HOME/cron-output 2>&1

#

# This is really just an example script and may not work in your environment

# uless you modify it appropriately.
