Double-Take Availability provides affordable data protection, ensures minimal data loss and enables immediate recovery from any system outage. Double-Take Availability continuously captures changes as they happen and replicates those changes to one or more servers at any location, over any distance, so you always have access to a current copy of your data, applications and operating system. You can replicate to a disaster recovery site as far away as you would like, over standard IP networks, for maximum protection against data loss and improve performance by compressing the protected data before sending. With Double-Take Availability, you can implement failover clusters without shared storage or geographic limitations - eliminating the single point of failure and providing the freedom to locate cluster nodes anywhere.

Rated 4 out of 5 by Has greatly improved our disaster recovery time but even after ports are enabled still issues with server communication. Valuable Features:In Version 7.xx the most valuable feature to me is being able to carry out a test full server failover in which case the primary server is still up and running.Improvements to My Organization:Double-Take has greatly improved our disaster recovery failover time.Use of Solution:I have used Double-Take for over 4 years now.Deployment Issues:Yes I encountered issues with deployment. The information provided in the guide just stated about 2 or 3 communication ports but even after these ports are enabled there are still issues with the 2 servers communicating via double-take. There are also issues during job creation. When all security is relaxed on the servers and firewalls it works fine. So we need more information as regards required windows services, communication and management ports, antivirus exclusion rules…etcStability Issues:The solution in itself was stable but is very dependent on bandwith.Scalability Issues:None.Customer Service:The customer service rep I interacted with was very forth-coming and helpful. I will rate it very high.Technical Support:I recommend that the support team improve on the windows skills. On several occasions they were unable to assist with *.msi issues that caused the double-take installer not to work.Initial Setup:The initial setup was very straight forward.Implementation Team:In-House.Disclaimer: I am a real user, and this review is based on my own experience and opinions.
