eDirectory Backup Script for Linux

0 Likes

This is a little script I put together to get backups of eDirectory from a Linux box. NDSBackup is a good utiltity - you can even schedule it, but I had a need to backup multiple trees, and I also did not want to manage backup directories, or archival directories for that matter. So I put together a really quick shell script to do some of that for me.

Usage:

edirbackup.sh [-t][-s]

-t denotes the name of the tree you are going to backup.

-s denotes the server you wish to backup from. (preferebly a replica server)

Example:
edirbackup.sh -t my-tree-name -s myserver.mycompany.com

The script takes a full tree backup, and a seperate backup for the schema on each tree. It then mails each report to whomever you want.
It also handles directory creation past the intitial backup directory. Nothing special, I just did this because I was lazy.

  • I have updated the script a little for current SLES10sp4 and above to match directory structure with eDir 8.8x.
    I use this mainly to backup the NICI files nightly using a cron job. I have placed this in a new folder off the root, \backup, made the script executable and have it run around 11:30 pm which works for us.
    It also cleans up after 7 days or whatever you want which I pasted in from other cool tools.

    30 23 * * * root /backup/nicibackup.sh

    script is as follows:
    nicibackup.sh

    #!/bin/sh

    -t specifies tree to run backup against.
