A backup is doing a copy of files to a second medium such as a tape or a disk for pre-caring of losing the original data. Therefore a backup can protect unexpected data loss and errors. To do a backup, firstly files that are used should be organized, secondly make a schedule for doing a backup then finally test and check whether it works or not.
Tape, which is the original storage media for computing technology, was supplanted by disk technology as the “primary storage media”.(Toigo, 2000, p. 156) By using the tape media, tape backup system became the traditional security backup technology for the large and small size companies and so on.
