Daily, weekly, monthly, yearly backup script

[francs]

Hi All

Some customers still like to do daily, weekly, monthly, yearly backups. Tsm don't really provide for it, so I created archive management groups for it and wrote this script to determine which type of backup should be done It then calls the tsm client with the correct management class. Hopefully someone can use this script and/or make some improvements/comments on it.

It is currently in use on an AIX 5.2 system.



Thanks
