DOUBLE-TAKE®
Accessible and affordable data protection for disaster recovery, high availability
and centralized backup.
Sure, you back up your data. But how frequently? How much data
would you lose in a disaster between backups? How quickly can you
recover from a disaster? How long would you be without access to
critical applications and data?
Double-Take® from Double-Take® Software goes beyond periodic backup to provide accessible
and affordable data protection, ensure minimal data loss, and enable immediate recovery
from any disaster or system outage. Double-Take 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, locally or at a recovery site miles away.
In the event of a disaster, Double-Take lets you recover from your target servers in minutes,
if not seconds. What's more, Double-Take delivers better protection than many hardware-based
solutions, and it costs tens of thousands less. Start with as few servers as you like, scale
organically as your data requirements grow, and get a fast and continuing return on your
investment.
Quickly restore access to data and applications.
When disaster strikes, Double-Take can immediately reassign the source server identity to a
target server. You're up and running again in minutes, with minimal or no loss of data and
productivity. Compare that to the hours or days required to rebuild a server from backup tapes.
Replicate over any distance to any location.
Unlike costly synchronous mirroring solutions that limit your geographic options or require
specialized network connections, Double-Take works over any distance using your
existing IP networks. Locate your target server as far away as you would like to ensure
maximum protection against outages or disasters.
Don't sacrifice performance for protection.
By replicating only the bytes that change, Double-Take uses the absolute minimum bandwidth
required to back up your data. Plus, powerful advanced features like Flexible Bandwidth
Scheduling and Intelligent Compression allow you to control when and how much network
bandwidth Double-Take can consume at different times. The superior features within
Double-Take make it the best choice in data protection for WAN-based replication.
Protect your existing investments.
Double-Take is server, storage, network, and application independent - it works with the
services you have today and will work with whatever best-of-breed hardware and software
you need tomorrow.
Choose the proven leader.
Thousands of companies – including more than half of Fortune 500 corporations – protect their
data and applications with Double-Take. Industry giants such as Microsoft®, Dell® and
Hewlett-Packard® have chosen Double-Take as the software engine driving their high
availability and disaster recovery solutions. Compare it to the competition like they did,
and you'll choose Double-Take too.
PRODUCT OVERVIEW: DOUBLE-TAKE®
Double-Take®: Proven enterprise-class data protection that fits
your infrastructure and your budget.
Continuous, asynchronous, byte-level replication. Double-Take
monitors changes to all protected files and replicates 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. Get the flexibility to choose best-of-breed
hardware and software as your enterprise grows.
Application independent. Patented STAR (sequential transfer
asynchronous replication) technology enables complete data replication
integrity for virtually any application.
Certified Windows compatibility. Double-Take is certified for all
editions of Windows Server 2003 and Windows 2000.
Snapshot Support. 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. Using the Double-
Take Application Manager console, configure for manual, automatic or
scheduled snapshots of business-critical data.
64-bit support. Double-Take provides 64-bit versions that run on
Windows Server x64 Edition (AMD64 and EMT64) or Windows Server 2003
for Itanium-based systems. Get the enterprise-class data protection you need
for your high scalability Windows environments.
Streamlined issue monitoring. Double-Take Management Pack for
Microsoft Operations Manager allows you to monitor issues on all
Double-Take servers across your enterprise and alerts you to only important
events, allowing you to stay aware of, respond to, and demonstrate accountability
for server and application services levels.
Flexible Bandwidth Scheduling. Limit network use of Double-Take
during busy work hours and increase or remove these limits during non-peak
times for very efficient replication with the least amount of impact on
production resources.
High availability and failover. Set your production server to failover to
a second server in the event of a failure.
Integrate with existing backup solutions. Use replicated data to
perform remote backups and snapshots at any time without impacting your
production server.
Windows Server 2003 clustering support. 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.
Use standard network protocols. Replicate over any existing IP
network – LAN, WAN, VPN or NAT – so you can deploy without additional
infrastructure costs.
Many-to-one failover. Allow multiple production servers to use the same
target server.
Intelligent Data Compression. Improve performance and reduce
network usage by compressing only the data that will benefit.
Protect Exchange, SQL Server, Virtual Systems, Sharepoint,
and more – and bulletproof your business continuity, data migration,
centralized backup, and server consolidation operations.
