Never been able to fully grasp the notion of delete input/delete input all when backup up Archivelog with rman.
Tied to the same issue is the configure Archivelog deletion policy to backed up X times to disk.
Deleting input, or deleting input all, seems counterintuitive to me when the deletion policy is set to 7 times to match an overall backup policy of 7 days.
Is there anyone here who can explain to someone who may be just a little dense how this all plays together? And what should the Archivelog deletion policy be if the goal is to have one week’s worth of backups available at all times? All backups are weekly backed up to a tape drive. With seven days as overall, and 7 times on Archivelog deletions policy, am I backing it up 7 times or 7 times 7 times?
Thank you for any help anyone can offer……
