Remote replication copies data to a secondary site as part of a disaster recovery plan; it traditionally involved backing up application data, but it is now possible to replicate entire virtual machines too. QSG will utilize the expertise of our staff and our valuable partners to deliver true disaster recovery as a service.
Is your business prepared for an emergency? Can you afford to lose data due equipment failures or viruses? Use our remote replication services to keep your critical business data secure and quick to recover. When all else fails QSG delivers.

We’ll help you choose the right remote replication solution for your business to best suit your disaster recovery plan.
Synchronous replication is primarily used for high-end transactional applications that require instant failover. Often used for disaster recovery, it is preferred for applications that cannot tolerate any amount of data loss. It is more expensive than asynchronous replication and may slow the application performance due to the addition latency. Data is usually written to primary storage and the replica simultaneously. This way the data is constantly up-to-date and remains synchronized.
Asynchronous replication writes data to primary storage first and then copies that data to the replica. This causes a delay before data is copied to the secondary site. The main benefits of this type of replication are it’s lower cost and ability to work over long distances. Since the replication does not occur in real time, asynchronous replication can tolerate some degradation in connectivity. It is typically used to provide high availability for critical applications with nearly instantaneous failover.
