  • 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

    • 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)

    • 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.

    • Using any file copy technology, copy the virtual system disks to DR site.
    • Doubletake Software continuously replicates the data between the VMs.
    • When disaster strikes…the DR site takes over as primary: No extra config needed
