RPO, RTO & MTD in Business Continuity & Disaster Recovery Plan(BCP & DRS) π±π₯β β
RPO: Recovery Point Objective
- Recovery point objectives are about data loss tolerance.
- RPO is the term used in business continuity to identify the maximum targeted period in which data can be lost without severely impacting the recovery of operations.For example, if a business process could not lose more than one day's worth of data, then the RPO for that information would be 24 hours.
- RPO is very useful to help determine the frequency of backups for a given system.
RTO: Recovery Time Objective
- Recovery time objectives are about restoration goals.
- RTO is a term used in business continuity to identify the planned recovery time for a process or system which should occur before reaching the business process's maximum tolerable downtime. For example, if a business process could not sustain for more than one day without normal operations, then the first RTO should be less than 24 hours.
- RTOs can be helpful in determining what kind of recovery and/or redundancy may be required.
MTD: Maximum Tolerable Downtime
- Maximum tolerable downtime, also sometimes referred to as Maximum Allowable Downtime (MAD), represents the total amount of downtime that can occur without causing significant harm to the organization's mission.
- MTD is important to define so continuity planners can select and implement appropriate recovery methods and procedures to ensure downtime does not exceed acceptable levels.
