Beginning with general availability in ONTAP 9.9.1, SnapMirror active sync provides Zero Recovery Time Objective (Zero RTO) or Transparent Application Failover (TAF) to enable automatic failover of business-critical applications in SAN environments.

For each type of SnapMirror data protection relationship, the workflow is the same: create a destination volume, create a job schedule, specify a policy, create and initialize the relationship.

Beginning with ONTAP 9.3, you can use the snapmirror protect command to configure a data protection relationship in a single step. Even if you use snapmirror protect, you need to understand each step in the workflow.
