Hi,
We are using RMAN to perform oracle 9i database backups on disk. These backups are then moved to tape susing Tivoli Storage Manager using OS backup. With this approach we are eliminating need to integrate RMAN and TSM as well as additional license cost. Oracle 10g has "Flash Recovery Area(FRA)" to hold recovery related files (e.g. backups, archived logs etc.) on disks. I was wondering whether we will be still able to use our old backup methods with flash recovery area.
e.g. if I have 7 day retention period.
Day 1: Incr. backup (level 0) + Incr. backup 1(level 1), Backup FRA on tape
Day 2: Incr. backup (level 0) + Incr. backup 2(level 1), Backup FRA on tape
........
Day 8: Incr. backup (level 0) + Incr. backup 8(level 1), Backup FRA on tape

On Day 8, My Day 1 backup becomes obsolete and removed from fash recovery area to make space for other files. However, I still have OS level backup done using TSM for Day 1. So, If I need to recover my DB as of Day 1, I can restore OS level backup. But where should it be restored (Flash Recovery Area or other file system)? how do I tell RMAN to use this backup?

Thanks for your input.....
