Your Solution Needs What challenges are you facing in your DR plan? What types of servers do you want to protect? About how much data do you have to protect? Have you chosen a DR Site? What kind of connection will you have? Do you have an RTO and RPO defined? www.doubletake.com

The Keys to Recoverability Replication Host-based, real-time, byte-level, asynchronous replication across any distance with WAN optimization to minimize bandwidth usage and requirements Failover Real-time monitoring for automatic or manual failover for individual applications, file shares, and whole servers - locally or remotely Recovery Recover data or entire servers over any distance while users remain online, with minimum downtime www.doubletake.com

Data Protection System Friendly Asynchronous Replication – Low CPU Overhead – Defined Memory and Disk Usage – Write Order Intact Replication Bandwidth Friendly Data Movement – User-definable Replication Sets – Compression, Scheduling, Scheduled Bandwidth Throttling capabilities Point-in-Time Recovery – Integration w/Volume Shadow Copy Services www.doubletake.com

Failover Solutions Application-Level Failover (RTO 30min) – Applications like Exchange, SQL and File Servers using the Application Manager capabilities – Works with Cluster-based Deployments Full-Server Failover (RTO 30min) – Custom-developed applications or applications dependent on system state information – Replicate and Failover OS, Applications and Data – Works for all stand-alone Windows Servers – Assists in One-to-One Server Migrations www.doubletake.com

How Application Failover Works Source Target Replication Failover Monitoring IP ICMP or Heartbeat Monitoring Application Services Started Detect Failure in Seconds or Minutes Failover Name, IP and/or DNS Records Failover Active Directory Hostname Users can reconnect within minutes of failure Failover can occur across a LAN, WAN and even NAT Failover more than one Server Identity to the Same Target Server Failover Scripting for Custom Configurations www.doubletake.com

How Application Failback Works Source Target Restoration Replication Failover Monitoring Recover or Replace Source Server Failback Source Identity Restore Data to the Source Server Bring Source Application Online Users Reconnect Within Minutes Start Replication and Resume Failover Monitoring for Continued Protection www.doubletake.com

How Full-Server Failover Works Staging Area OS and Applications Data Volumes User and Application Data www.doubletake.com

Server Recovery Option Tier 2/Tier 3 Server Recovery (RTO 4-24 hours) Same Recovery Type as FFO Local, Remote or Both Restore to Physical or Virtual Systems Assists with “Swing-Server” Migrations www.doubletake.com

Double-Take Server Recovery Option Protect Multiple Production Servers With One SRO Image Server Recover Back to the Original Server, to New Hardware, or to a Virtual Machine www.doubletake.com

Double-Take Virtual Recovery Assistant 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. www.doubletake.com

How DTVI Works Must be running ESX Server 3.0.0 and VMware VirtualCenter 2.0.0 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) www.doubletake.com
