US Patent 11586489 Automated disaster recovery test verification

A Disaster Recovery (DR) verification process or system verifies readiness to execute a Disaster Recovery (DR) test. Such DR verification is automatically provided on a regular basis, with minimum impact on both a production and recovery environment. However, DR verification is only enabled at a time when no disaster recovery or DR testing of other sites is already under way. Configuration data needed for DR verification is constantly replicated from production to recovery, by dedicated data movers. DR verification allocates and configures recovery resources in an encapsulated environment, confirms successful their instantiation (such as boot up and network connections), and reports the outcome.
