"Webdata protection – immediate recovery of data. Replication of production data to a DR site, whether asynchronous, synchronous, or in an active-active configuration, provides a second level of protection. The data at the DR site can also be protected via automatically scheduled immutable snapshot protection, providing a third level of protection. " - Synchronous and asynchronous data replication

WebIn contrast, asynchronous data replication [16] allows writers to proceed without waiting for a replication to complete. The asynchronous data replication consistency is not as accurate as the synchronous method because even if a writer of block A returns, a replica of block A may still be in the replication process. WebMay 4, 2024 · 3. Synchronous replication (Metro/Sync) With Synchronous disaster recovery, we can achieve a zero RPO at the VM granularity level.

WebApr 11, 2024 · Unlike synchronous replication, asynchronous replication creates copies of data as per defined schedule. Asynchronous replication is designed to work over distances and uses less bandwidth; in comparison to its counterpart. Asynchronous replication is suitable for businesses that can endure longer RTOs (Recovery Time Objectives). WebAsynchronous replication takes snapshots on the replicated storage objects to create the point-in-time copy, determining the changed data to transfer and maintain consistency during the transfer. Consider the overhead of snapshots when planning performance and capacity requirements for a storage pool that will have replication objects.
