Checking Database backups are one of the main focus areas of a DBA. Time to time, DBA needs to check database backup status and see if its completed, failed, running etc. Also, DBA must be able to get the backup start time, end time and even the backup size for reference purpose. The below query gives answers to all the backup details in oracle.
