Question
A database administrator manages a database server that is running low on disk space. A lot of backup files are stored on the server's disks.
Which of the following is the best action for the administrator to take?
- A. Move all the backup files to external disks.
- B. Delete all the backup files containing data that is rated as classified.
- C. Delete all the backup files that are not required by the backup retention policy. Correct
- D. Delete all the backup files except for the most recent one.
Explanation
The backup retention policy defines which backups must be kept, so removing only the backups that fall outside it frees disk space without breaking recovery or compliance requirements. Moving every backup to external disks just relocates the problem and may move backups that should stay on managed storage, deleting by data classification ignores retention requirements, and keeping only the latest backup can make point-in-time recovery or required retention impossible.
