This tutorial explains how to make a full backup of an Oracle database (Oracle 19c in this example) to an other server with RMAN, so if you have a storage saturation or need to make a copy of Oracle database, may this can help you.
- Production Server:
- Hostname: wadodb1
- Connection name: wadodb
- db_unique_name: wadodb
- Standby Server:
- Hostname: wadodb2
- Connection name: wadodbsb
- db_unique_name: wadodbsb
Step 1: Connect to the primary as primary connection and to the second one as auxiliary connection, and make a full as copy Backup.
Note: You need just an instance with NOMOUNT State in the second server.
$ rman target sys/PASSWORD@wadodb auxiliary sys/PASSWORD@wadodbsb

Step 2: Make a full backup to the secondary server
