This tool is for: eDirectory versions where dsbk and eMBox supported.
If you have edirectory instances that are jumping from one node to another
in case of a failure, this script detects which instance running on which host,
then performs a backup of it with dsbk with proper hostname and timestamp tags.
You can add a cron job to run "backupedirs" at 04:00 AM everyday, for example.
If you're familiar with dsbk, you'll get the idea.
