Restore SAP Database using multiple copies.

Hi all,

I've succesfully setup netbackup to backup SAP. We have 4 policies:

SAP_DB_Daily

SAP_DB_Weekly

SAP_DB_Monthly

SAP_DB_Yearly.

My question is, when we go to restore a database using brrestore, do we also have to specify which policy to grab the data from? 

so as an example: 

brrestore -m full -c force -b <file> -d util_file -r d:\oracle\<SID>\11203\database\initSID.utl

Will netbackup know where to grab <file>?

Also, when we restore archive logs, will I also need to specify policy?

I was thinking of combining all SAP backups into one policy, but, wasn't sure how to configure the default-application and schedule for different retentions. So, I setup different policies. 

If you can shed some light, it would be very helpful. Thanks!
