feature guide
Double-Take for Linux utilizes patented replication and failover technology that continuously captures byte-level changes as they happen and replicates those changes to one or more target servers at any location.  Double-Take goes beyond periodic backup to provide accessible and affordable data protection from any disaster or system outage. 

Key Features

  • Continuous, asynchronous, byte-level replication - Double-Take monitors changes to all protected files and replicated only the actual bytes that change.
  • Unlimited distance replication - Replicate to a disaster recovery site as far away from your production server as you would like, over standard IP networks, for maximum protection against data loss from regional crises and other disasters.
  • Use standard network protocols - Replicate over any existing IP network, LAN, WAN, VPN or NAT so you can deploy without additional infrastructure costs. 
  • Bandwidth Throttling - User defined controls within Double-Take can limit the amount of the available network bandwidth it can use for data replication.  This allows replication to occur real-time without impacting users on the same network.
  • Open-file Mirroring and Replication - Double-Take doesn't require that applications be restarted each time additional files and/or directories are configured for replication.  Users, customers and applications remain online and active while Double-Take is at work. 
  • Integrated with existing backup solutions - Use replicated data to perform remote backups at any time without impacting your production server.
