We are running a 5Tb database backup which takes really a long time to backup and impacts the performance in general during the backup. We got a DataGaurd database in place which we want to utilize to run the RMAN backup on to avoid performance impacts and just use DG database for backup and DR purposes. My Question is if we run the backups on DataGaurd Database, How would a RMAN DG database backup would clear the archive logs from Primary production and from DataGaurd Database during the backup process? Any suggestions?

We have RMAN catalog running on Primary Server for now. So you are saying it would clearn the files from DG but not from Primary...? I am not sure if delete input would delete archivelogs from Primary or DG database.. Any suggestions..?

Existing configuration is to send backups over to tape directly via rman/tdp from primary node. We want to have these backups to tape configured on Datagaurd server/db to reduce the performance impact. Regarding disk are not accessible means was "database disks of Primary datbaase/archive location are not accessible from Datagaurd Server."...

See the CONFIGURE command in RMAN.
At the Primary you can
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
which allows the FRA at the Primary to delete archivelogs that have been applied on the Standby.
(The Primary and Standby must be communicating in a DataGuard configuration, not a manual standby)
