Double-Take Software is the leading provider of affordable software for recoverability, including continuous data replication, application availability and system state protection. Double-Take Software products and services enable customers to protect and recover business-critical data and applications such as Microsoft Exchange, SQL, and SharePoint in both physical and virtual environments.
Power outages, hardware malfunction, software failure, human error, and natural disasters are the most common causes for system downtime. The cost of downtime can range from lost business and productivity to cessation of operations, depending on the severity and duration of the failure. DoubleTake Software helps minimize the risk to business through real-time local and remote replication of critical data. DoubleTake also provides timely server and application failover.
The core of Double-Take Software technology is its patented real-time file data replication. After performing an initial mirror of selected drives, directories, and/or files, DoubleTake subsequently replicates - in real-time - only the byte-level changes to those datasets, instead of copying whole files across the network every time they change. For example, once a mirror of a large database file has completed, DoubleTake then replicates only the changes within the file as they occur. This significantly reduces the amount of time and bandwidth necessary to transmit the data.
DoubleTake uses standard TCP/IP to transmit data over a local area network (LAN) or a wide area network (WAN) with bandwidth throttling and encryption as options. Its support of multiple operating systems (including Microsoft Windows NT/Windows 2000/2003, and cross-platform replication that can be controlled from a common management console) help gear DoubleTake toward today’s heterogeneous server and storage environments. Simple Network Management Protocol (SNMP) integration and a complete command line interface allow automated monitoring and administration of DoubleTake via enterprise management systems. The feature-rich functionality of DoubleTake and its flexible configuration options can help provide many different types of protection suited for a variety of business requirements.
