How to backup and delete archivelogs older than # number of days

Question : How can one achieve the following while using RMAN to backup the archived logs?
Back up all archived redo logs until specified time and delete them after backing up, and also back up all the other archived redo logs that were not backed up before – all this with a single RMAN command.

Solution

Backup archivelogs older than 10 days and delete them

First let us look at the command to backup all archived logs older than 10 days and delete them:

RMAN> run { 
       allocate channel t1 type disk;
       backup 
          format '/recover/oracle/%d/arc_%d_%t_%s'
          archivelog until time 'sysdate-10' delete input; 
       }

The above will back up all archived logs older than 10 days and then delete them.

Backup all logs and delete logs older than 10 days only

If you would like to back up all archived logs and delete only the ones that are older than 10 days, you can do the following:

RMAN> run { 
       allocate channel t1 type disk;
       backup 
          format '/recover/oracle/%d/arc_%d_%t_%s'
          archivelog all 
          archivelog until time 'sysdate-10' delete input;
       }
