Introduction

Double-Take Availability for Windows provides real-time high availability and immediate disaster recovery so you never have to worry about downtime or the lost revenue and chaos that ensue.

Double-Take Availability ensures the availability of critical workloads. Using real-time replication and failover, you can protect data, individual applications, entire servers, or virtual machines. Identify your critical workload on your production server, known as the source, and replicate the workload to a backup server, known as the target. The target server, on a local network or at a remote site, stores the copy of the workload from the source. Double-Take Availability monitors any changes to the source workload and sends the changes to the copy stored on the target server. By replicating only the file changes rather than copying an entire file, Double-Take Availability server allows you to more efficiently use resources.

In physical/virtual infrastructures that deliver mission-critical services to end-users, the 24x7 availability of data and applications is crucial for maximizing service quality, user satisfaction, and consequently, revenues. In such environments therefore, the uninterrupted functioning of Double-Take Availability server is imperative. Issues such as intermittent breaks in the availability of Double-Take Availability server, excessive load conditions, and delayed connectivity, if not promptly detected and resolved, can significantly impact the delivery of underlying services. You thus need to periodically monitor Double-Take Availability server for such availability and operational snags, and initiate early measures to redress them. This is where the eG Enterprise lends helping hands to administrators for continuously monitoring the Double-Take Availability server.
