Elastic Compute Service:StartPairDrill

Last Updated:Sep 25, 2024

Starts a disaster recovery drill to ensure the continued replication and clone the data from the last recovery point of the secondary disk to a new disk. This helps you test the completeness and correctness of applications that are deployed on the disaster recovery site on a regular basis.

Operation description

After the disaster recovery drill is complete on the secondary disk, a pay-as-you-go drill disk that has the same capacity and category as the secondary disk is created in the zone where the secondary disk resides. The drill disk contains last-recovery-point data that can be used to test the completeness and correctness of applications.
