In designing a backup strategy that will be consistent with a disaster recovery strategy, the PRIMARY factor to be taken into account will be the:
A . volume of sensitive data.
B . recovery point objective (RPO).
C . recovery’ time objective (RTO).
D . interruption window.

Answer: B

Explanation:

The recovery point objective (RPO) defines the maximum loss of data (in terms of time) acceptable by the business (i.e., age of data to be restored). It will directly determine the basic elements of the backup strategy frequency of the backups and what kind of backup is the most appropriate (disk-to-disk, on tape, mirroring). The volume of data will be used to determine the capacity of the backup solution. The recovery time objective (RTO) ― the time between disaster and return to normal operation ― will not have any impact on the backup strategy. The availability to restore backups in a time frame consistent with the interruption window will have to be checked and will influence the strategy (e.g., full backup vs. incremental), but this will not be the primary factor.
