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

Correct option is A

A tape drive is a backup device that provides a convenient way to create full system images and complete backups. However, restoring data from tape drives can be time-consuming due to the sequential access nature of tape storage.
(b) Network-attached storage (NAS): This is incorrect because NAS devices provide quicker access to backups and typically offer faster restoration times than tape drives.
(c) Solid-state drive (SSD): This is incorrect because SSDs offer faster data retrieval and shorter restoration times, making them a more efficient option for backups compared to tape drives.
(d) DVD-RW disc: This is incorrect because while DVD-RWs can be used for backups, they generally do not offer the same capacity or convenience as tape drives for full system backups.
