Automatically back up your LDAP database

Here's the script I use to automatically back up the LDAP database on 10.3 Server. If you stick it into /etc/periodic/daily, the system cron jobs will run it automatically for you when they do the other system maintenance jobs. Don't forget to chmod +x it once you're done editing the script.

You can download the script from here.


#! /bin/bash
#
# Usage: put this into /etc/periodic/daily as something like 800.backup_LDAP
# and the stock Apple cron jobs will run it automatically every day.
