Protect and Recover SQL Server Data with Double-Take® from Double-Take Software.
While SQL Server 2005 offers options for improving database protection and recovery, none of them is intended to provide a complete disaster recovery solution. In today's environment, corporate and regulatory mandates as well as service level agreements drive many of these requirements beyond what native SQL Server data protection options can provide.
Double-Take from Double-Take Software is the industry leading replication and disaster recovery solution, providing real-time data replication, patented database crash consistency, unlimited distance replication, monitoring and automated failover capabilities for SQL 7.0, 2000 and 2005.
Most Microsoft SQL protection strategies involve a nightly full backup of the data, typically to tape. However, this method only protects yesterday's work. Any data that has been entered into the database since the nightly backup is not protected and would have to be manually recreated if the production system failed. Since critical data is created and manipulated every second of every work day, you have to ask yourself: Can you afford to lose up to an entire day's worth of data?
A SQL Server protection strategy supported by Double-Take Software provides up to the minute data replication capabilities for all SQL data. Double-Take Software provides organization's with a solution for SQL protection that provides distinct advantages over manual Microsoft SQL built-in replication capabilities: Double-Take Software saves more data real-time and restores that data much faster.
With features from Double Take Software such as built-in bandwidth control, data can be replicated and restored over long distances without service degradation, putting the recovery and restore responsibilities for remote locations in the hands of the experts back at the datacenter.

Microsoft Exchange Recovery Solutions from Double Take® Software
To say that email is a critical application is an obvious understatement. Few applications are more integral to an organization's day-to-day operation. For many companies, an hour of Exchange downtime can cost hundreds of thousands of dollars in lost productivity. How can you justify a disaster recovery and high availability solution for Microsoft Exchange that does not provide immediate and up-to-the-second recovery of Exchange data? Therefore, Exchange recovery is critical.
Double-Take Software provides organizations with Exchange recovery solutions for disaster recovery, high availability, and centralized backup by protecting all changes to Exchange data at the byte level rather than the full file or block level. You get up-to-the-second Exchange data protection with maximum performance and minimal use of your network and system resources - for immediate Exchange recovery should an outage occur
Complete protection of Exchange requires a lot more than management of on-site and off-site tape backups. While traditional tape backup is an excellent tool for long-term archiving, true Exchange recovery for the sake of business continuity requires real-time data protection which enables disaster recovery and high availability. Having a solution that is cost-effective, hardware independent and scalable is something every IT manager should seriously consider.
An Overview of Double-Take Application Manager for Exchange.
Double-Take Application Manager (DTAM) for Exchange is designed specifically for the configuration and management of Double Take for the protection of Microsoft Exchange environments. It automates the setup and configuration of replication and failover monitoring of Exchange servers for rapid and successful deployment. Features such as auto-discovery of servers and key Exchange data files simplify the process down to just four steps and reduce the risk of human error.
Exclusive features such as the pre-flight check help to ensure that all necessary settings within the environment are configured correctly for replication and failover of Exchange. Any errors identified are listed along with suggestions for resolution. DTAM for Exchange checks over 50 different configuration criteria and can automatically correct a majority of them on the administrator’s behalf. This helps achieve a seamless, error-proof deployment.
DTAM for Exchange performs recovery and fail back of Exchange servers with a minimal window of downtime. By performing recovery tasks while users remain online, Exchange downtime is reduced to just the few moments that it takes for Double-Take to stop and start the necessary Exchange services and relegate processing back to the production server. Exchange recovery is quick and easy.
DTAM for Exchange demonstrates our commitment to providing customers with innovative solutions for protecting business-critical data. It integrates the management of application protection into a single console allowing for increased automation and ease of setup, resulting in improved protection, reduced recovery times, and a higher level of application availability.

How to Ensure Exchange Recovery
Exchange systems can come in a variety of flavors and configurations to meet nearly every business need and budget. By far the most common system employed today is the Stand-Alone Exchange server (SAES). SAES systems are a single server running all components of the Exchange system on the same physical or virtual system. This means the server acts as a mail-transport system, routing system, SMTP server and gateway and mail and public folder database server. It may also provide spam filtering, anti-virus scanning or any other function related to Exchange.
The end result of this configuration is that you have a single server that must be protected - all your eggs are quite literally in one basket. Double-Take can provide you with data replication of all key information for the Exchange system and any other systems running on the production server. In addition, the Double-Take Application Manager (DTAM) for Exchange can help you prepare a secondary server to take over in the event of a loss of the primary. DTAM for Exchange provides application-specific configuration, availability and management features and is a free toolkit available as part of Double-Take.
DTAM for Exchange will select the appropriate directories and volumes on your production machine which need to be protected, configure Double-Take replication, and configure the secondary server’s Exchange configuration to match that of the production machine. It will also prepare the secondary server to execute the necessary commands to start Exchange services during an outage and allow failover to occur. During this configuration process, you can specify what network path the replication systems should use, if data should be compressed for transmission and if you wish to manually initiate the failover process (“one-click failover”) or have it happen automatically after a timeout you define.
During an outage, DTAM will either automatically initiate a failover if the production server is unreachable for the amount of time you set, or alert you and wait for you to initiate the failover manually. Alerting for either type of failover scenario is available via SNMP, SMTP and the Windows Event Log, in addition to the native Double-Take management tools. Regardless of which failover methodology you choose, the procedure for restoring services for end-users is the same.
First, Double-Take’s DNS Fail Over (DFO) component will update Active Directory DNS servers to re-route end-users to the recovery server. You may specify any and/or all DNS record types for update, depending on what systems you need re-directed. Double-Take Software Professional Services can also assist you with providing automated failover for customized DNS or Exchange deployments as well.
After DFO re-routes the end-users, the Double-Take Exchange Failover (EFO) component will dynamically re-assign all mailboxes and Public Folders from the failed server to the recovery server. This will allow end-users to regain access to their information the next time they attempt to connect to Exchange. Internal testing and real-world feedback has revealed that this failover process is very fast and creates a relatively small load on your existing DNS and Active Directory infrastructure - approximately 14,000 users can be moved to secondary server in around 7 minutes. In fact, while conservative failover estimates are suggested to be placed at 45 minutes for total failover, most Double-Take customers report being able to failover in less than 20 minutes – even when performing the failover across a WAN connection.
Finally, DTAM will prepare and start the appropriate Exchange and 3rd party services (anti-virus, mobile mail, archiving, etc) on the recovery server. This last step re-establishes a live Exchange server for your end-users to connect to. Outlook clients may need to be re-started, but no end-user configuration will be required. In addition, other components such as Outlook Web Access (OWA) and other e-mail integrated system will simply pick up where they left off.
