Hi,

We have production database.

We would like to have 15 last online full backups (sheduled once a day) and to be possible to restore database to a point in time only between last backup and current time

If I configure retention window for 15 days, archive redo logs in last 15 days are also backed up, and this consumes lot of space, which is a problem here (database files and arhive logs are of a huge size).
(There is enough space for 15 full backups and archive log for one day though)

How to configure RMAN for this?

I was thinking about configuring retention policy for 15 days and adding this lines at the and of a daily RMAN cronjob:
backup archivelog all not backed up;
CROSSCHECK BACKUP DEVICE TYPE DISK;
DELETE NOPROMPT ARCHIVELOG ALL;

Is this good for what I want to achieve?

Thank you

Use incremental backup each day instead of full backup and a full backup per week then you will (most likely) take less space and then maybe have enough.

Thank you Michel,

I will definetely try this.
If incremental backup would be less then fifth of a size of a full backup, this would definetely solve my case.

Also, use the "AS COMPRESSED BACKUPSET" option if you are not doing it.
