Disaster Recovery and Data Transfer with Veritas Volume Replicator
Few would argue against the importance of robust disaster recovery plans for your applications and services. Events over the last year or so have reminded us how easily service outages can impact an organization's revenue and undermine consumer confidence. At a basic level, the efficient recovery of services is dependent on the availability of the data, and one of the most common ways to achieve this is through data replication to a remote site.
Veritas Volume Replicator (VVR) from Symantec is a replication solution over IP that maintains a consistent copy of your application data at remote sites. Synchronous and asynchronous modes of replication are supported and a bunker option provides a zero recovery point objective for asynchronous configurations. As a host based replication solution, VVR is independent of both application and storage and supports up to 32 remote locations (at any distance) making it a truly flexible and scalable solution.
VVR is an extension of Symantec's Veritas Storage Foundation software and can leverage Storage Foundation's FlashSnap (snapshotting) technology to support remote site data processing. This allows backups, reporting, decision support services or business intelligence analysis, for example, to be run at the remote site without impacting your production service or disrupting the replication.
One of the limitations of many other replication solutions is that they require a full synchronization after a DR event before the service can be returned to the primary site. The "Fast Resync" capabilities of Veritas FlashSnap are employed by VVR so that only data that has changed needs to be resynchronized. This can dramatically reduce the time required to fail-back a service to the primary location.
VVR is not only useful during DR events. Migrating your service to the secondary site during planned maintenance of your primary is a straight-forward task and can be performed with a single click or command. This keeps your service available and helps to reduce the contention between planned maintenance and service availability. VVR's ease of installation and configuration also makes it an ideal tool for data transfer projects such as array migrations, platform transformations or datacenter relocation.
Finally, many applications have relationships and dependencies that combine to provide a business service. Symantec recognize this and along with Veritas Cluster Server (VCS), Symantec Virtual Business Service (VBS) and Veritas Operations Manager (VOM), VVR helps to contribute to an automated, complete and effective DR plan.
So if you're looking for a robust, flexible and scalable replication solution to protect your applications or enable your data transfer requirements, take a closer look at Veritas Volume Replicator from Symantec.
