What backup solution requires an administrator to insert media into a storage system for retrieval?

The backup solution that requires an administrator to insert media into a storage system for retrieval is the offline backup method. Offline backups involve storing data on physical media, such as tapes or disks, which are not continually connected to the network or storage system. In order to access the backed-up data, an administrator must physically retrieve the media and insert it into the appropriate storage device.

This method is often used for long-term storage, archiving, or for disaster recovery purposes. Because the media is offline, it adds a layer of security and protection against cyber threats while making data retrieval a manual process, which reinforces control over access.

In contrast, other options like SAN (Storage Area Network) and cluster configurations typically involve online systems where data can be accessed without the need to insert physical media. FCON (File Control Unit) is related to managing storage but does not refer specifically to the media retrieval process in the same way as offline backups do. Understanding the differences among these options helps clarify the unique characteristics of offline backup solutions.
