Which one of the following factors does not play a role in choosing the type of backup media to use?
A. How frequently a file changes.
B. How long you need to retain the backup.
C. How much data needs to be backed up.
D. How frequently the backed up data needs to be accessed.
Correct Answer: A
Explanation/Reference:
Explanation: Your choice of backup media will depend on its capacity, its shelf life and the time it takes to access the data. The frequency of file changes is irrelevant.
Incorrect Answers:
B:Different backup media can be kept for varying periods of time. You should find out from the manufacturers how long a backup media can be kept without losing its data.
C:Obviously, your choice of backup media will depend on the amount of data to be backed up. For example, a CD-ROM can hold around 700MB of data while tapes can hold up to hundreds of gigabytes of data.
D:Your choice of backup media will also depend on the time it takes to retrieve data from the media. Reading data from a CD-ROM or DVD is much quicker than reading data from a tape.
