Hi All,

We are using Unity 300 with RecoverPoint/Async 5 Minutes. We did failover with Sync from Source Unity. 

Q1- A LUN having 4 TB size took almost 4 hours to failback from destination Unity to Source Unity. Why it takes 4 hours despite for minimal change of data happened on that 4 TB LUN at Destination Site?

 

Q2- While doing Failback from Destination Unity to Source Unity what does means  of below mentioned phrase?

All sessions will start a synchronization to the original source storage resource. The synchronization could be either delta or full synchronization depending on the replicated snapshots.
