The document discusses using Doubletake for virtual machine replication and disaster recovery. It describes how Doubletake works with VMware virtual infrastructure to provide real-time replication of virtual machines between sites. The replication occurs at the virtual disk level and supports failover of entire virtual machines within minutes in the event of a disaster at the primary site.

1. Business Continuity & DR with Virtualization & Doubletake A view at using Doubletake with VM’s in order to provide Continuity Ultan Kinahan MCITP, MCTS, MCSE, MCP [email_address] http://ultankinahan.spaces.live.com

2. So What Really Constitutes a Disaster? Some Examples; Fire, Flood, Power Loss, Hacker or any Natural Disaster

3. 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 `

4. Virtualization - Benefits Hardware independence Hardware pooling Single Step Recovery Faster recovery Hardware availability Simplified administration
