RMAN Incremental Backup - Whether to keep archive log post incremental 1 diff and cumulative?

Hi,

I have small doubt related to archive log retention post incremental backup.

Currently am following below mentioned RMAN incremental backup strategy:

- Incremental level 0 database backup along with Archivelog on Sunday and post backup delete Archivelog.

- Incremental level 1 differential database backup along with Archivelog on Mon to Fri. Archivelog not deleted post backup.

- Incremental level 1 cumulative database backup along with Archivelog on Sat and post backup delete Archivelog.

Doubt is whether I can delete archivelog post incremental level1 diff backup? My simple requirement is to have daily backup available with minimal disc space usage hence am following above mentioned strategy however I feel that deleting archivelog post incr1 diff  backup won't be any issue.

Howdy, Stranger!
