A customer wants to protect production data using local and remote replication on a pair of VMAX arrays located 100 km apart. Both VMAX arrays are fully configured with virtually provisioned thin volumes.
The customer has a near zero Recovery Point Objective (RPO) and wants to replicate the production volumes to the remote array, while maintaining a separate backup copy of the production data on the local array.
Which replication options do you recommend they implement?
