I have 2 ASM diskgroups DATA and FRA and created RMAN level 0 and Level 1 backups of the datafiles, archivelog files (along with control file and spfile). Archivelogs are in DATA group and the RMAN backups are FRA.

Level 0 backup runs every Sunday at 2am and level 1 backup runs Monday through Saturday at 2am.

What (all) should I do/configure/set in RMAN to backup the ASM flash recovery area group to tape?

I undrestand that the command is 'backup recovery area'. is that all? what channel(s) do I have to set. I am totally lost.

I have been looking online and documentation for sometime now but not able to get the answer I want. Not sure if I am looking right or not.

Can someone guide me? Thanks !

BACKUP RECOVERY AREA will ONLY backup to tape. Therefore, you should ensure that you have a tape channel configured or that you allocated one prior to issuing the command.

Thanks

I was thinking that I should do(assuming that each node in the cluster has its own local tape drive) one-time configuration to configure one channel for each node in the cluster.
CONFIGURE DEVICE TYPE sbt PARALLELISM 2;
CONFIGURE DEFAULT DEVICE TYPE TO sbt;
CONFIGURE CHANNEL 1 DEVICE TYPE sbt CONNECT 'user1/pwd1@node1';
CONFIGURE CHANNEL 2 DEVICE TYPE sbt CONNECT 'user2/pwd2@node2';
BACKUP RECOVERY AREA;

this should backup everything in the flash recovery area to tape. Am I missing something?

That would appear to be correct, however I don't have access to a RAC database to test. You should run those sequence of commands and review the RMAN log to ensure that you are obtaining the parallelism. The worst that should happen is that only one channel is used.

Is is possible to backup the Flash Recovery Area to a disk location instead of a tape? All the posts indicate that "BACKUP RECOVERY AREA" only backs up to a TAPE device. Unfortunately, we don't have a tape drive on the Oracle server and the db_recovery_file_dest area keeps getting full. We have increased the size three times already, but I was wondering if there was a way to flush out the flashback logs. We have a guaranteed restore point (that's all we need for our purpose), and do not care about the additional flashback logs.

The FRA can indeed only be backed up to tape. If you don't need the flashback database capability, then you can disable it and alleviate the flashback logs.
