StartPairDrill - - 阿里雲

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 verify the integrity and correctness of applications that are deployed at the disaster recovery site on a regular basis.

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 verify the integrity and correctness of applications.
