Recovery time objective (RTO)
Recovery time objective (RTO) is the length of time that it takes to recover from an outage (scheduled, unscheduled, or disaster) and resume normal operations for an application or a set of applications.
The recovery time objective may be different for scheduled, unscheduled
and disaster recovery outages. Different data resilience technologies will
have differing RTO times. Possible values for RTO are:
- More than 4 days is acceptable
- 1 to 4 days
- Less than 24 hour
- Less than 4 hours
- Less than 1 hour
- Approaching zero (near immediate)
