Doubletake High Availability

High Availability and Failover Solutions - Recovery made easy.

In today's business climate, the high availability of applications including email is crucial. The advent of technology such as RIM BlackBerry® devices and other mobile messaging solutions means that not only can employees access email wherever they go, the expectations of email are that it is constantly available. How can you protect yourself against downtime and ensure complete data protection with 24/7 high availability?

Traditional solutions, such as tape backup and hardware mirroring, are not without flaws. Tape backup poses a potential risk in that data backups must be performed when the system is idle - meaning that as much as a day's worth of data could be lost. Tape recovery time can also be below many business's recovery time objectives (and does not provide high availability).

A more cost-effective answer to a high availability solution is asynchronous host-based replication for high availability. Support for non-proprietary hardware and storage systems means you can leverage your existing resources. You'll also get real-time data protection without distance limitations ensuring high availability for all your business-critical applications - including email.

Real-time data replication at the byte level, regardless of application, is a much more efficient use of computing and bandwidth resources for high availability.With Double-Take Software solutions all of your applications can have cost-effective, real-time data protection and high availability.

High availability and failover. Set your production server to failover to a second server in the event of a failure. Unlimited distance replication. Fail over to a disaster recovery site as far away from your production server as you would like, over standard IP networks, for maximum protection against data loss from regional crises and other disasters. Flexible Bandwidth Scheduling. Limit network use of Double-Take during busy work hours and increase or remove these limits during non-peak times for very efficient replication with the least amount of impact on production resources.

Implementing a high availability solution can be simplified using virtual technologies and result in a much lower overall cost. Because most applications typically require their own dedicated server, providing high availability or failover protection to these applications requires a dedicated target server.With Double-Take, each application can replicate and fail over to a dedicated virtual session on a single physical server, ensuring high availability and eliminating the need to deploy and manage multiple target machines. The result is an above standard level of high availability and application protection at a much lower TCO.
