Which of the following answers BEST indicates the most important part of a data backup plan?

A.
Testing the backups with restore operations

B.
An effective backup plan

C.
A reliable network infrastructure

D.
Expensive backup hardware

Explanation:
If you can’t restore lost files from your backup system then your backup plan is useless. You could have the
best backup system and plan available but if you are unable to restore files then the system cannot assure data
availability.
Develop an effective disaster recovery plan and include in that plan a good backup strategy that meets the
needs of your organization. Be sure to include periodic recovery practice operations to prove the effectiveness
of the system.
Incorrect Answers:
B: This question is asking for the BEST answer for the most important part of a data backup plan. An effective
backup plan is what you want; however the MOST IMPORTANT part of the backup plan is the ability to restore
the data.
C: A reliable network infrastructure makes it easier to backup and restore your data. However, network
reliability is not the MOST IMPORTANT part of a backup plan. The ability to restore the data is more important.
D: Expensive backup hardware is not the BEST answer. If your expensive backup hardware cannot restore
your data, it is no good to you.
