Compliance Retention lock with Database Application Agent

Hi, all

We have Data Domains 2500 with Compliance Tetention Lock Licenses.

We backup our Oracle Databases with RMAN and Database Application Agent 4.5 direct to the Data Domains.

DDOS Version is: Data Domain OS 6.0.2.0-575017

DAAgent Version is: emcdbappagent-4.6.0.0.1.x86_64

I have to create a script to set the atime of the RMAN Backup Files to the future to activate the Retention Lock.

As discribed in:

https://support.emc.com/kb/492081

When I mount the mtree to my linux system I'll found such file structure:

/mnt/dd01/xd2700.visana.ch/25/2.0/data_ss

/mnt/dd01/xd2700.visana.ch/25/2.0/meta_keys

/mnt/dd01/xd2700.visana.ch/25/2.0/meta_rec

etc..

I guess the follow:

data_ss  are the folder with the real backup data

meta_keys are the folder with the real filenames but these are only links to anywhere (all are 2KB)

meta_rec are some other meta data i dont know

Does anyone know where this fle structure is described?

or does anyone know witch files that I have to set with the atime in the future to activate Retention Lock correctly

Thank you for any help
