Recovery-Point Objective (RPO):

This is the point in time to which systems and data must be recovered after an outage.

It defines the amount of data loss that a business can endure.

A large RPO signifies high tolerance to information loss in a business.

Example, if the RPO is six hours, backups or replicas must be made at least once in 6 hours.

Recovery-Time Objective (RTO):

The time within which systems, applications, or functions must be recovered after an outage.

It defines the amount of downtime that a business can endure and survive.

Businesses can optimize disaster recovery plans after defining the RTO for a given data center or network.

For example, if the RTO is two hours, then use a disk backup because it enables a faster restore than a tape backup.
