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.
Hardware independent:
Double-Take allows the flexibility to choose best-of-breed hardware and software as your enterprise grows.
Flexible Bandwidth Scheduling:
Limit network use of Double-Take during busy work hours and increase or remove these limits during nonpeak times for very efficient replication with the least amount of impact on production resources.
Use standard network protocols:
Replicate over any existing IP network, LAN, WAN, VPN or NAT so you can deploy without additional infrastructure costs.
