Understanding the Scenario:

The customer has mission-critical applications that need to be backed up to a remote location with a latency of 7 ms.

Nutanix Technology Options:

AsyncDR: Provides asynchronous replication with typically higher RPO (Recovery Point Objective) than NearSync.

NearSync: Offers near-synchronous replication with RPO as low as 1 minute, suitable for low-latency connections like the 7 ms latency mentioned.

Metro Availability: Provides synchronous replication with zero RPO but requires a higher bandwidth and lower latency connection (typically sub-millisecond).

Leap: A comprehensive DR orchestration solution that includes AsyncDR and NearSync but is not a standalone replication technology.

Evaluation of NearSync:

NearSync is designed to provide low RPO (as low as 1 minute) by taking frequent lightweight snapshots.

It is well-suited for environments with moderate latency (like 7 ms) and can handle the backup requirements efficiently without the need for extremely low latency and high bandwidth required by synchronous replication solutions like Metro Availability​​​​.

Conclusion:

Given the latency of 7 ms and the need for short RPO, NearSync is the most suitable Nutanix technology to provide the shortest RPO.
