Images Duplication from Tape to Data Domain expire very fast

Hi all,

We has been duplicate images from tape to disk (data domain), because the backup retention in tape are differents from the data domain backup.

So, we can see that the image duplicated to data domain expire after a few minutes.

System Informations:

Netbackup version: 7.6.0.4

Master and Media Server: Windows Server 2008

Data Domain: EMC

someone already had a similar problem?

Thanks all.
