So What Really Constitutes a Disaster?
Some Examples;Fire, Flood, Power Loss, Hacker or any Natural
Disaster
DR Challenges
Complexity Management and provisioning Hardware and software upgrades
Reliability Complex solutions are hard to test Requires specialized training for
personnel
Cost Additional hardware Additional tools and training
`
Virtualization - Benefits
Hardware independence Hardware pooling
Single Step Recovery Faster recovery
Hardware availability Simplified administration

Products Available To Us?
Must be running ESX Server 3.0.+ and VMware Virtual Center 2.+
Leverages VMware APIs for virtual machine snapshot functionality
Snapshots include the entire VM (OS, Apps, Data) and can be used with a non-Windows Guest OS
Snapshots are time-coherent across all virtual disks configured for a protected virtual machine
Extends staging of virtual machines across geographical boundaries (WAN replication)

How DTVI Works
Protect physical or virtual servers directly into VMWare .VMDK files with real-time replication
Protect the entire server including the OS, applications and data
Protect multiple source servers with a single virtual target server
Failover automatically or manually within minutes
Lower TCO with virtualization and many-to-one consolidation.

DoubleTake Replication
Data Volume
1. Using any file copy technology, copy the virtual system disks to DR site.
2. Doubletake Software continuously replicates the data between the VMs.
3. When disaster strikes…the DR site takes over as primary: No extra config needed
Primary Site (NYC) DR Site (Chicago)
Questions?
None… Cool Thanks!
