Double-Take for Windows

Features

Continuous, asynchronous, byte-level replication over any distance
Double-Take monitors changes to all protected files and replicates only the bytes that change. Replicate to a disaster recovery site as far away as you would like, over standard IP networks, for maximum protection against data loss. Improve performance by compressing protected data before it is sent.

High availability and failover
Choose between either application-level orfull-server failover to configure an alternate system to take over for your production server in the event of an outage.

Point-in-Time Recovery
Double-Take integrates with Microsoft Volume Shadow Copy Service to allow you to schedule and recover from up to 64 point-in-time copies of data on your Double-Take target.

Supports Clustered Deployments
Protect up to eight nodes in a single cluster; replicate to or from MSCS clusters of up to eight nodes, and automatically respond as cluster resources move from node to node.

Centralised Reporting and Analysis
The Double-Take Reporting Center feature offers detailed, custom analysis and reports of your entire Double-Take environment. The rich reporting and dashboard views of the Double-Take Reporting Center make it easy to manage even the largest Double-Take deployments.

Protects Exchange, SQL Server, Virtual Systems, SharePoint, and more
Bulletproof your business continuity, data migration, centralized backup, and server consolidation operations.

The Double-Take Application Manager Feature.
The Double-Take Application Manager (DTAM) feature is designed specifically for the configuration and management of protection for Microsoft Exchange, SQL Server, SharePoint Services and Windows File Services. It automates the setup and configuration of real-time protection and availability management for these business-critical applications.

Server Auto-Discovery
Auto-discovery of servers allows you to configure replication and failover from the user interface with ease.

Auto-Selection of Protected Data
For each application being protected, DTAM automatically discovers data to be replicated.

Integrated Recovery and Failback
To ease recovery procedures and reduce downtime, DTAM provides integrated restore and failback capabilities to automatically recover data to the original production server and initiate failback.

Pre-Flight Check
DTAM includes many points of validation to reduce or eliminate the potential for errors.

Benefits

Improved Data Protection
Double-Take protects data in real-time, reducing your exposure to data loss from a full day's data to seconds or less.

Disaster Recovery Protection
Up-to-the-minute offsite protection is an important part of a your business continuity strategy. Double-Take works efficiently over slower WAN links.

Reduced Downtime
Failover is fast and automatic. Your exposure to downtime is reduced or eliminated.

Multi-Platform Management
Double-Take provides consistent solutions for Windows and UNIX. All Double-Take products can be managed from GUI, Text Based or Command Line Clients running supported platforms locally or remotely attached.

Cross-Platform Data Interchange
Data can be mirrored and replicated between your Double-Take machines running on different OS platforms.

Enhances Backup Performance
By giving your existing third-party backup system access to open files, Double-Take improves backup reliability. In addition, the option of centralizing backup operations on the target server simplifies management, improves performance, and reduces cost of ownership.

Select the amount of bandwidth you want to use
Double-Take for NT allows you to select the amount of bandwidth you would like to dedicate to replication. If you have a 128K link you can limit replication to a maximum of 64K reserving the remainder for standard network traffic.
