Nothing disturbs the peace like server failure.

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.

• Comprehensive, real-time application and data protection
• Flexible deployment options
• Easy-to-use management
• Surprisingly affordable

High Availability and Disaster Recovery:

• The most comprehensive high availability and disaster recovery for physical and virtual servers on Windows
• Real-time application and data protection
• Use existing hardware, software and network
• Full server protection and failover
• Failover executed in minutes, not hours, and supports dissimilar hardware
• Supports MS Exchange, SQL Server, Oracle, SharePoint, BES and more
• Microsoft Volume Shadow Copy Service integration allows you to schedule and recover from up to 64 point-in-time copies of data on your physical or virtual target
• No distance limits for backup server
• Near-zero data loss
• Microsoft Windows 2000 and 2003 certified at all levels

Simple Management:

• Features one-click failover and restore
• Ensures easy installation and optimized configuration with IntelliStart™
• Provides automated, push button failover for physical or virtual machines to the second host on demand in an outage with SwitchAssistant™
• Validates settings with pre-flight check and auto-fix
• Monitors and auto-switches critical systems
• Presents centralized reporting and analysis
• Improves performance by compressing the protected data before sending
• Simulates replication traffic* and estimates needed bandwidth with the Double-Take Availability Throughput Diagnostics Utility
• Provides email event notifications
• Simplifies management with forwarded replication statistics and events via SNMP to your enterprise management tools
• Ensures the integrity of replicated data on with patented write-order consistency *except ESX

Virtualization

• Unifies high availability and remote availability across physical and virtual environments, including VMware vSphere and Microsoft Hyper-V
• Failover physical servers to virtual environments with failover-time virtualization technology that automatically provisions a new VM to match the production server
• Protect and failover VMs over any distance without the need for underlying storage replication
• Reduce the cost and management overhead of duplicate physical infrastructure at a DR site by using a virtualized DR site
• Protect virtual environments using real-time continuous replication of VMs with host-level management of failover policies
• Management of all physical and virtual failover protection in a single solution, for superior manageability
• Failed over VMs are partition-aligned to the underlying physical disks for optimum performance of I/O intensive applications in virtual environments
• Enables no-downtime full-server migrations to physical or virtual servers
• Integrates seamlessly with Hyper-V management interfaces

Clustering:

• Eliminates single points of failure
• Efficiently replicates data changes and allows cluster nodes to quickly restore application services after a failure
• Guards against data corruption by keeping clusters from failing over to a node that has suspect data
• Implements failover clusters without shared storage or geographic limitations
• Allows you to locate cluster nodes anywhere
• Provides off-site cluster failover capabilities
• Turns Microsoft Windows Server clusters into Shared Nothing Clusters
• Stretches cluster nodes between physical locations while still using native failure detection and failover
• Ensures write-order preservation of logical application writes
• Ensures production nodes don't suffer performance degradation because of intermittent network failures or node failure
• Uses minimal CPU overhead while delivering real-world measured performance of 65-75% compression for database applications
• Maintains complete storage independence
