During the recovery process, RTO and RPO should be the main parameters of your disasterrecovery...

Recovery Point Objective (RPO) refers to the maximum tolerable period in which data might be lost from an IT service due to a major incident. It is a critical parameter in disaster recovery and business continuity planning. RPO is determined based on the acceptable data loss in case of a disruption of operations. It indicates the point in time to which data must be recovered after an outage to resume business operations and avoid unacceptable consequences associated with a break in business continuity.
