Nutanix Recovery Plans are designed to orchestrate the failover of complex applications that may consist of multiple virtual machines with different protection requirements. However, there are rules regarding which types of replication schedules can be mixed within a single plan.
Nutanix supports mixing Asynchronous and NearSync replication schedules within the same Recovery Plan.
This is because both Async and NearSync are fundamentally snapshot-based, " passive " recovery models where the system pulls from recovery points stored at the destination cluster. However, the system generally restricts or warns against mixing Synchronous replication with other types in a single orchestrated plan.
Synchronous replication (syncrep) is an " active-active " or " stretched " model that behaves differently during a failover compared to snapshot-based models. In some software versions, including entities protected by synchronous schedules with those on async/nearsync within a single plan can cause the failover task to fail validation because the orchestration logic for zero-RPO failover is distinct from snapshot restoration.
Therefore, while mixing Async and NearSync is a supported and common practice, administrators must be cautious with Synchronous workloads.
