Data Asynchronous Replication

Asynchronous replication is important for off-site data protection, business continuity and disaster recovery because it allows you to copy mission-critical data over a WAN to a secure remote location. This data can be recovered within a short recovery point and with minimal disruption.

Replicating data to an offsite location guarantees that you are up and running even in case of a disaster. It allows a robust disaster recovery plan to fail over to a remote site, knowing that your data is intact.

Remote Replication and Backup allows you to:

• Replicate data off-site over a WAN using standard IP/Internet
• Have data stored remotely for protection
• Create a Disaster Recovery plan
• Ensure Business Continuity and fail-safe data protection

Learn about Synchronous Mirroring vs Asynchronous Replication:

With synchronous mirroring each write operation requires control confirmation from both storage nodes. This approach guarantees reliability of data transfers but is demanding in bandwidth (insomuch that mirroring will not work on higher latency networks).

With asynchronous replication confirmation from each storage node is not required. Asynchronous replication does not guarantee data integrity in the event of storage or network failure; hence, some data loss may occur what makes asynchronous replication a better fit for backups and disaster recovery where some data loss is acceptable.

For zero data loss, use StarWind CDP replication. CDP utilizes more overhead on the SAN than asynchronous replication and is better for servers like database and email where zero data loss is preferred, but less critical servers yet can be replicated asynchronously.
