In BE 2012, disk storage is managed by DLM and you set in your job how long you want to retain your backup set.  See this blog and my article on how DLM works.

I have not come across a way to globally change the retention period for existing backup sets.  You might have to go to the Storage tab, click on the disk storage.  Click on backup sets on the left-pane, right-click on the backup sets that you want to delete and then delete them.

You then change the retention period in your job so that new backup sets would be retain for a shorter period of time.

This document is not applicable to BE 2012.  It is only applicable up till BE 2010.

What about the below steps:-

 

Select the Storage Tab in the BE2012 Interface.

Select your disk storage device and click the ====> for the DETAILS view.

in the details view select the Backup Sets option.

I just scrolled to the bottom of the list which is the oldest backup sets,

Select large groups of backup sets using Shift+Left Click

Right click the selected backup sets and select DELETE.

Yes to All when prompted to delete.

 

Thanks,

Nayab

One more question .. Is the Retention period is something to be changed from Policies itself or need to change from the storage tab???

And we end up calling EMC support to recover lots, lots, lots of Tb. We are still investigating why does this happens since we only deleted some incremental sets... By the way, we did it all from BE console, not from Windows. 

I believe it's something regarding deduplication in our Data Domain storage and the way the sets are linked, I Don't know yet, I'm not paid enough to do that kind of research :D

 

By the way, EMC support it's outstanding.

 

 

A second of your life, ruined for life.
