Q: What is a Recovery Time Objective (RTO)?
A: A Recovery Time Objective (RTO) is the amount of time it takes from the moment you initiate your disaster recovery (DR) failover to when you are able to use the VMs in the new DR environment.
A lower RTO is better because it will typically mean that disruption to operations are minimized, users can get back to work quicker and your websites are back online faster. Low RTOs means less chance of your customers or other external parties even realizing you were down for any period of time.
RTO examples
5-10 minute RTO
it means every VM comes online at the same time after a disaster event.
20-30 minute RTO
If you have selected to power some VMs up only after other VMs have successfully powered up, then you can expect an RTO of around 20-30 minutes.
