While the buzz surrounding agentless high availability solutions for Hyper-V and vSphere is lively, agent-based replication is still very much in need.

Chandler Concrete has worked hard to build a strong reputation for outstanding customer service. As part of that commitment, their dispatch system is available nearly 24 hours a day, 7 days a week. In order to shorten their recovery time, they wanted to switch from tape to Double-Take Availability. Vision’s James Senecal walked the IT team through installation and testing to ensure everything was configured properly and it worked so well in the testing phase that the IT team decided to kick it up a notch and convert to Microsoft Hyper-V virtual servers. The entire implementation went without a hitch.

For Newfoundland Power, uptime is so important that their RPO is just one minute. When they realized there was no way their existing tape system could deliver, they recognized they might be facing up to 24 hours of downtime if a server went down. Ultimately they turned to Double-Take Availability in order to match their commitment to superior customer service with a high availability and disaster recovery infrastructure. Now, they have a business continuity plan in place that provides 24x7 application availability and fast data recovery in case of an outage.

Applications are getting more and more complex. It's rare these days to find applications that truly exist on a single physical or virtual server. As applications begin to spread out across multiple servers, it becomes more difficult to address disaster recovery.

When a large national bank ran into a problem transferring a host server into their domain, they realized critical data was no longer being sent to their target server. In the event of an outage or a disaster they would not only lose revenue related to downtime and data loss, they’d lose customer confidence and risk violating compliance laws. Like a growing number of corporations, the bank had a modern, complex infrastructure that required significant expertise to diagnose and fix the problem. They called Vision’s CustomerCare and Chad Jackson quickly discovered that the culprit was a locked Double-Take activation code that was different than on the previous server.

Recovery Point Objectives (RPO) are another key metric when outlining a Disaster Recovery (DR) plan. This particular metric refers to the amount of data that can be lost due to various disaster scenarios, and as you might expect, the lower the number the better the plan.
