Backup Exec 2012 OST Usage Report

Hi all,

I use BE2012 with a Dell DR4000 OST Device and that device is now approaching the used capacity limit. The problem is that this appliance is a kind of black box and there is no way to know directly the reason : poor deduplication rate, old retained backups...

The Storage tab on the backup exec console does not give much information, nothing concerning dedup rate or used disk space.

I've found some powershell command related to tape devices, but nothing concerning OST devices.

Is there a way to troubleshoot that and have a better reporting of OST disk space usage ?

Thanks a lot.
