Understanding RPO and RTO

The disasters could occur unexpectedly and it could take down the whole data center in an application region. In the real world, a well designed disaster recovery solution would help restore the applications and related data at the time of disaster.

There are two critical metrics to measure how timely the applications and data can be recovered and how much data loss can be tolerated.

  • Recovery Time Objective(RTO)
  • Recovery Point Objective(RPO)
