Why is protecting Hyper-V Important?
•
•
•
Customers are adopting Hyper-V virtualization technology
in production for server consolidation, etc.
These customers fear that virtualization and consolidation
will put “All The Eggs In One Basket”
Double-Take for Hyper-V provides real-time replication
and failover for virtual machine environments
– Disaster Recovery for virtual machines
•
Real-time replication of virtual machine data
•
Real-time replication of virtual machine data
– High Availability for virtual machines

Solution Protection Overview
• Asynchronous Replication
‒ Provides recovery point of minutes, seconds or zero
‒ No distance limitations on replication, if you can ping it you can
replicate to it
‒ The ability to choose the individual files & folders to protect
‒ Very low overhead on production servers 0-4%
• System state protection
‒ Protect the entire server, including OS, applications, security
and registry setting and the data with real-time replication as
opposed to scheduled solutions that deliver poor RPO

What are the Benefits of using the
Double-Take Software Replication Engine?
•
Asynchronous Replication
•
•
•
•
•
Data integrity
•
•
Byte Level replication as opposed to block/file level cuts network traffic significantly
Features such as compression, bandwidth throttling and scheduled bandwidth usage enhances
performance on slower networks or across the WAN
Point-in-Time Recovery
•
•
Guarantee's application crash consistency with write order preservation and transactional
replication
Bandwidth Friendly Data Movement
•
•
•
Provides recovery point of minutes, seconds or zero
No distance limitations on replication, if you can ping it you can replicate to it
The ability to choose the individual files & folders to protect
Very low overhead on production servers 0-4%
Integration with snapshot technology or continuous data protection solutions to provide point-intime, this will help protect against you against data corruption
System state protection
•
Protect the entire server, including OS, applications, security and registry setting and the data with
real-time replication as opposed to scheduled solutions that deliver poor RPO
