Double-Take Availability for Windows provides affordable data protection, fault tolerance and enables immediate recovery from any system outage at the push of a button. Continuous data replication over any distance means that you always have access to a current copy of your data, applications and operating system (OS).
Double-Take Availability monitors changes to all protected files and replicates only the bytes that change. Resource friendly technology allows you to replicate to any disaster recovery site, over standard IP networks, for maximum protection against data loss. Choose between application-level or full-server failover to configure an alternate system to take over for the production server in the event of an outage. Double-Take Availability protects Exchange, SQL Server, SharePoint and more.
