When developing a disaster recovery plan, what is the result of choosing a particular recovery time
objective for a system?

A.
Determines the type and location of the backup media

B.
Determines how often to take a backup of the system

C.
Determines how long to retain backup copies

D.
Determines how many transaction logs should be backed up

Explanation:

Recovery-Time Objective (RTO): The time within which systems and applications must be
recovered after an outage. It defines the amount of downtime that a business can endure and
survive. Some examples of RTOs and the recovery strategies to ensure data availability are listed
below:
RTO of 72 hours: Restore from tapes available at a cold site.
RTO of 12 hours: Restore from tapes available at a hot site.
RTO of few hours: Use disk-based backup technology, which gives faster restore than a tape
backup.
RTO of a few seconds: Cluster production servers with bidirectional mirroring, enabling the
applications to run at both sites simultaneously.
