Database Software

Hi there,
currently, we are running following RMAN backup strategy:

<li>Saturday: Level 0 Backup of database to disk
<li>other Days: Level 1 Backup of database to disk
<li>daily writing the backup files from disk to tape by external tool ( HP Dataproector file based backup)
<li>Recovery Window of 7 day's configured in RMAN
<li>weekly crosscheck to delete obsolete backups from disk

So far, so good.

Now, we have bought some new backup storage device and we are trying to use the MML of HP Data Protector to write backup directory on "tape" instead to local disk.

In general backup by using the MML is working, so that's no problem.

But, we are faceing a configuration topic regarding RMAN Recovery Window vs. HP Data Protector Backup Protection.

On current setup, RMAN is manageing the backups and knows, because auf "Recovery Windows Configuration", which backup files are absolete and can be deleted from disk.
This is completly working as expected.

When integrating the HP Data Protector, the HP Data Protectory is manageing his own policy for keeping and deleting the backups as "Backup Protection".
Protection Level are
<li>None: No Protection, Backup will be overwritten next time
<li>any time frame: Backup will be stored, until configured timeframe is over
<li>permanent: Backup will be stored for ever

How ever, Data Protector isn't knowing anything about, which backup is required for the required "RMAN Recovery Window". HP Data Protector delete the fbackup, where the protection level was none, or the protection time has gone by.

Is there any know way to just use the MML as "Storage" and let the RMAN completly manage, which backups can be deleted?

I hope, my "problem" is clear and someone has an idea.
Thanks for your minds.
