Delete noprompt obsolete

Question

Hello,
RMAN >delete noprompt obsolete;
The "delete obsolete" or "delete noprompt obsolete" will delete the archivelog files past the retention from disk and will also delete any backups on disk or tape.
My retention redundancy is 1. According to the statement above, it will delete the archivelog files and any backups on disk or tape from a previous day. My issue is that I want to delete backups on disk based on the redundancy 1, but keep the archivelogs for 5 days then delete archivelogs. So, the "delete noprompt obsolete" will not work in my case.
So, I replace this "delete obsolete" with this command "delete noprompt archivelog All completed before 'SYSDATE-5';" to delete any archivelogs that are more than 5 days old. That would solve my archivelog issues, but what happens to my backups on disk (I want to delete backups based on redundancy 1)?
Thank you.

1) delete noprompt ARCHIVELOG UNTIL TIME 'SYSDATE-5';
2) DELETE noprompt BACKUP COMPLETED BEFORE 'SYSDATE-2' DEVICE TYPE DISK;
Does redundancy 1 retention take care of the #2 ? If so, why do I need the #2.
Thank you again.For your archivelog deletion policy, you can try what was suggested earlier
delete noprompt archivelog until time 'SYSDATE-5';With respect to your backups, you can have the retention policy left as it is by setting it to redundancy 1 and add this to your level 0 backup script/full backup script (if not added earlier).
crosscheck backup;
delete noprompt obsolete;My Bad.
I am of the opinion that the above command (delete noprompt obsolete) deletes even the archives that fall within the 5 days time.
