How does vSphere Replication operate?

vSphere Replication is designed to facilitate disaster recovery by enabling asynchronous replication of virtual machines (VMs). Asynchronous replication means that the changes made to the VMs at the primary site are not immediately sent to the secondary site. Instead, these changes are batched and replicated on a schedule, which allows for more efficient use of bandwidth and is particularly beneficial when replicating over long distances.

This method ensures that in the event of a failure at the primary site, the organization can quickly recover from the replicated VMs at the secondary location, minimizing downtime and data loss. This capability is essential for businesses that need to ensure continuity of operations without the need for real-time data synchronization, making it a crucial component of a comprehensive disaster recovery strategy.

Other options mentioned either imply features that vSphere Replication does not support, such as synchronous replication or creating backups on a schedule, which are handled through different mechanisms in the VMware ecosystem.
