Industry-leading Double-Take replication software and NSI

professional services provide a comprehensive solution for protecting

Microsoft SQL Server Systems

NSI Software, Inc. (NSI(R)) today introduced Double-Take(R) for Microsoft SQL Server(TM), a comprehensive NSI software and professional service offering that extends the benefits of data protection to one of the most widely used Microsoft applications. The NSI solution set enhances Microsoft SQL Server native copy utilities by leveraging Double-Take software's ability to replicate all data and non-data changes in real time without the need to take the server offline.

Companies such as Poe Financial Group, one of Florida's largest property insurers, recognize the business-critical nature of SQL data (see today's related release). JL Morrison, senior database administrator at Poe Financial Group uses NSI Double-Take software to minimize the negative impact to customers should downtime occur. The company stores the core of its business operations on a Microsoft SQL Server-based policy management system. Morrison notes that any downtime or interruption to data availability undermines the trust of their customers.

NSI Double-Take for Microsoft SQL Server is available in a variety of configurations to achieve the right level of protection to meet budget and business requirements. Available configurations include:

-- High Availability: Replicates SQL Server data and applications

to another target server onsite providing local failover

protection. Should the original server go- down, users have

immediate access to the replicated data and can use the target

server as a stand-in production server.

-- Disaster Recovery: Replicates onsite SQL Server data to

servers at a separate, offsite server -- at any location, over

any distance. In the case of an outage or disaster, users are

guaranteed immediate access to up-to-the-minute replicated

data that is available and online for recovery or for

redirection of users.

-- Remote Availability: NSI is the only vendor to provide local

high availability, plus real-time replication to remote

servers at a separate disaster recovery facility at any

location. When a simple server outage strikes, users are

provided with immediate failover to local replicated data and

applications. In the event of a site or regional failure,

users have a remote up-to-the-minute replica of production

data.

-- Complete SQL Server Protection: For the maximum protection

possible, NSI Complete SQL Server Protection enhances source

and remote target servers using GeoCluster Plus software,

which extends Microsoft Clustering Service (MSCS) clusters by

eliminating the single point of failure within the shared disk

resource.

All of the NSI Microsoft SQL Server solutions are augmented by the company's experience and expertise in designing and deploying cost-effective data availability solutions based on a best-of-breed methodology including:

-- Preproduction Planning: A thorough assessment of the network

and SQL Server infrastructure that identifies critical servers

and data and determines the implications of server failures.

The result of this process is a strategy to achieve data

protection goals within an expected service level.

-- Capacity Planning: An analysis of the "rate of change" of SQL

Server data to estimate the optimal bandwidth and product

configurations needed to achieve the best possible performance

and scalable protection.

-- Knowledge Transfer: A process that effectively transfers NSI

expertise to the IT staff responsible for ongoing maintenance

and support of NSI deployments.

"Whether protecting a mission-critical client/server application or an e-commerce Web site, businesses realize the value and necessity of continuous replication to protect their operations," said Bob Guilbert, vice president of marketing and business development for NSI Software. "Offering a SQL solution set is a natural extension of our product and service offerings and extends our goal of providing affordable and reliable data protection to Microsoft application customers."

NSI Double-Take(R) for Microsoft SQL Server is immediately available from NSI and its Xcelerate Partners.
