SSC CGL Tier II - 26 October 2023 • Computer • Q139

Which backup device provides a convenient way to create system images and complete backups, but may require a lengthy restoration process?
 

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. Tape drive.

A tape drive is a backup device that offers a practical solution for creating system images and comprehensive backups. It uses magnetic tapes to store large amounts of data, making it suitable for long-term storage and archiving. However, the restoration process from tape drives can be lengthy compared to other backup methods. Retrieving data involves sequentially reading through the tape, which can be time-consuming, especially if large volumes of data need to be restored or if the backup is fragmented.
