Answer (C) is correct . The offsite location where an organization’s computer backup files are kept must be temperature- and humidity-controlled and guarded against intrusion just as the main processing center is. Just as important, it must be geographically remote enough from the site of the organization’s main operations that it would not be affected by the same natural disaster. It does an organization no good to have sound backup procedures if the files are not accessible or have been destroyed.
Answer (A) is incorrect because Magnetic tape is a sound, though slow, medium for the storage of backup files.
Answer (B) is incorrect because Inadequate ventilation, while undesirable, is not the most compromising of the choices.
Answer (D) is incorrect because If data will only be used on equipment owned by the organization and will not be transmitted over network lines, leaving it unencrypted will not compromise the soundness of backup-and-rotation procedures.
