Netvault retention policy


just a quick question. We use Netvault with Qorestor 7.

I cannot see any option in Netvault (or in the administration guide) to configure a retention policy like: keep backup of the last 7 days, then 1 weekly backup for 4 week...

The only option for retention is In manage  Manage sets --> Advanced Backup Options --> Edit --> Backup life.

Am I right?

Thank you
