To address an organization’s disaster recovery requirements, backup intervals should not exceed the:

A.
service level objective (SLO).

B.
recovery time objective (RTO).

C.
recovery point objective (RPO).

D.
maximum acceptable outage (MAO).

Explanation:
The recovery point objective (RPO) defines the point in time to which data must be restored after a disaster so
as to resume processing transactions. Backups should be performed in a way that the latest backup is no older
than this maximum time frame. If service levels are not met, the usual consequences are penalty payments, not
cessation of business. Organizations will try to set service level objectives (SLOs) so as to meet established
targets. The resulting time for the service level agreement (SLA) will usually be longer than the RPO. The
recovery time objective (RTO) defines the time period after the disaster in which normal business functionality
needs to be restored. The maximum acceptable outage (MAO) is the maximum amount of system downtime
that is tolerable. It can be used as a synonym for RTO. However, the RTO denotes an objective/target, while
the MAO constitutes a vital necessity for an organization’s survival.
