instance that contains a database named ABC_Prod. During the night a daily full backup of
ABC_Prod is started at 03:15, a differential backup is performed every 90 days minutes and a
transaction log backup is performed every 20 minutes.

break starting at 11.30. How can you meet her request while keeping the database backup files in
order for future backups and restores?
