I am receiving this error when attempting to backup a file using RMAN. The server that this is one has multiple databases which backup and has multiple files in the failing database that do back up. Oracle indicates it may be A Veritas error but according to Veritas, everything is configured properly in the policy.

ORA-19673: error during proxy copy of file /u05/oradata/file.xxx

Other recorded erros are ORA-19676 and ORA-19511. Is there something wrong with the particluar file that is inconsistent with what Veritas may want?
