What is the expected behavior of NearSync Replication if the replication window is missed due to write volume?

1. The system continuously tries to get to the NearSync schedule

2. The administrator needs to re-enable it manually

3. Protection Domain transitions back to the hourly schedule

4. NearSync stops working and fails over to the remote site

The correct answer is: The system continuously tries to get to the NearSync schedule

NearSync Replication is designed to ensure data consistency and minimize data loss by providing near real-time replication of data to a remote Nutanix cluster. When the replication window is missed due to high write volumes, the system's expected behavior is to continuously attempt to catch up with the NearSync schedule. This mechanism is crucial as it allows for eventual consistency by trying to minimize the lag created during periods of excessive write activity. This continuous attempt to align with the predetermined NearSync schedule ensures that the replicated data remains as close to real-time as possible, preserving data integrity across clusters. The goal is to maintain as little data loss as possible and ensure that if the site experiences a failure, the most current data is available. In contrast, other potential outcomes such as needing manual re-enablement or reverting to an hourly schedule would not facilitate the real-time benefits intended with NearSync Replication. Similarly, stopping all operations and failing over to a remote site would be far too disruptive to data management practices, undermining the purpose of continuous replication. Thus, the system’s inherent design focuses on resilience and continual alignment with the replication schedule.
