Dear Expertslook at this scenario 1- I have created a backup device2- I have created a maintenance plan full backup and run it - with overwrite option on the backup device3- I have created a maintenance plan differential backup and run it with append option on the same file of backup device4- I have created a maintenance plan log backup with append option on the same backup devicewhen i made restore database from the backup device i found three files the full and differential and log backup5- I ran again the differential backup maintenance plan ( suppose to be ran everyday night )when i made restore database I found only two backups the full and the last differential !!!what I want to do is to take a full backup every week , append differential backup everyday and append log backup every hourwhen I ran the last differential backup it erased the first differential and log backups, why is this happening and how to apply this scenario and keep the all differential backups on the same backup device Thanks lot
