How to not back up archived Oracle logs

When backing up archive logs in Oracle databases, archive log files stored in the last few days are not deleted.

For example:

Backup archivelog all;

Delete noprompt archivelog all completed before 'sysdate-7'; Save the archived logs for seven days locally.

If this is the case, the archive will be backed up again.

Add a clause not backed up 1 times to remove the archived logs.

The command is as follows:

Backup archivelog all not backed up 1 times; do not back up the archive that has been backed up last time
