10g ASM aware backup agent

Environment: Oracle 10gR2 (10.2.0.3 with patch)
Oracle Standard edition (works only with ASM)
Only Backup option for this env is RMAN
OS: Windows 2003 server

Need to know, once we have taken the db backup on EMC-SAN (DBF and ARCHIVELOG files) using RMAN (files managed by managed by ASM and are not visible to windows OS), how do we tranafer the backup (files) to tape on daily basis.

I know one option can be using RMAN to go directly to tape.

Do we have option to backup to storage and then to tape.
Do we have any ASM-aware agent or any other way available to backup files from storage (EMC-SAN) to tape

Please advice.

you backup your backups to flash recovery area then configure rman to use sbt

CONFIGURE DEVICE TYPE sbt PARMS='...'

then run

BACKUP RECOVERY AREA;

this will send your asm backups to tape, you need to integrate rman with your backup agent previously
