System backups should always be performed real time.

Backups should be stored in a secured location onsite for easy access.

The tape rotation schedule affects how long data is retained.

Backup media should be restored only in case of a hardware or software failure.

Correct Answer: C

The tape rotation schedule affects how long data is retained because different tape rotation schemes (like Grandfather-Father-Son) determine the frequency and duration for which backup tapes are kept. This directly impacts the retention period of the backup data.
