rman policy

Hello,

We are backing up our database (Oracle 9i) using RMAN - level 0 backup on Saturday night, incremental level 1 - Sunday to Friday.

We would like to retain all backups for 3 month, so we configured RMAN to retain backups:
configure retention policy to recovery window of 90 days;

I also need to keep level 0 copy from the first Saturday of the month up to three years.

Could you please help me on this ?

Thank you!

Inessa.
