How to backup Migrated Secondary Data through NDMP

Hi to All,

We want to Backup the Whole Data which is migrated to Secondary storage via EMC DX NAS.

Can you please help us to do that?

Thanks in advance.

We are using following settings for NDMP:

HIST=y
UPDATE=y
OPTIONS=NT
DIRECT=n

We have tried to take the backup. But it is picking only the Stub from Primary Storage, not the backend FULL file.

Any settings we have to modify?
