Method and System for Assessing Thoroughness of a Disaster Recovery (DR) Failover Test

Disclosed is a method and system for assessing thoroughness of a disaster recovery (DR) failover test. The method and system evaluates/analyses the thoroughness and efficiency of a DR test that is cautiously performed several times per year on one or more system volumes (Volumes) connected in a network. The tested volumes are analyzed for determining whether Input/output (IO) workload during the test is indeed representative of normal production workload. Thereafter, evaluated results are presented to user for judging whether the DR test is realistic, and identify areas where improvements could be made.

In accordance with the method and system, the user specifies that a DR test has been carried out for a set of volumes during a specified time period. These volumes could be identified explicitly, based on servers that they are associated with, or a grouping mechanism that represents volumes associated with an application or an organization. The method and system analyses the set of volumes during the time period and identifies copy service targets associated with the volumes. This process can account for multi-target copy services as well as chained copy services, in which at least four volumes are chained together.

For each volume, the method and system validates that a failover has occurred by validating volumes that are targeted for driving to a consistent state during the t...
