Which of the following backup methods is most appropriate for off-site archiving?
Correct Answer: C
Explanation/Reference:
Explanation:
All data should be archived. A full backup copies all the data from the system to the backup medium. After the full backup has finished, the backup media is physically transported to another off-site location.
Incorrect Answers:
A: Archiving should copy all the data, but an incremental backup copies only the files that have been modified since the previous backup.
B: There is no special off-site backup method. Instead use a standard full backup and transport the backup media to the other site.
D: Archiving should copy all the data, but a differential backup copies only the difference in the data since the last full backup.
