Which of these options is the most secure procedure for storing backup tapes?

A.
In a climate controlled facility offsite

B.
On a different floor in the same building

C.
Inside the data center for faster retrieval in a fireproof safe

D.
In a cool dry environment

Explanation:
An effective disaster data recovery strategy should consist of producing backup tapes and housing them in an
offsite storage facility. This way the data isn’t compromised if a natural disaster affects the business’ office. It is
highly recommended that the backup tapes be handled properly and stored in a secure, climate controlled
facility. This provides peace of mind, and gives the business almost immediate stability after a disaster.
