Question
Which backup device provides a convenient way to create
system images and complete backups, but may require a lengthy restoration process?Solution
A tape drive is a device that stores computer data on magnetic tape, especially for backup and archiving purposes. Like an ordinary tape recorder, a tape drive records data on a loop of flexible celluloidlike material that can be read and also erased. Tape backup is the practice of periodically copying data from a primary storage device to a tape cartridge so the data can be recovered if there is a hard disk crash or failure.
