-A Recovery Drill is a synthetic failover that performs all the same steps as an actual failover. Recovery Drills run with the same Source Server Launch Settings and Point in Time snapshots that a Recovery would. As a result, we recommend adjusting any Source Server Launch Settings to isolate Drill Instances when necessary to avoid production or business impact. You can use verification post-launch actions when performing a drill to ensure that Launch Settings are accurate. A Recovery Drill can be performed with an individual source server, or it can include as many source servers as necessary to simulate the recovery of an application.
