Neverfail for Microsoft® SQL Server

Delivering Application Availability and Continuous Data Protection for SQL Server

Today's SQL Server environments are always changing, with data being constantly appended, reformatted and deleted across a rapidly evolving network of databases. Typical backup systems — which can't keep up with this volatile database environment — simply don't provide you with the SQL Server high availability and disaster recovery solution you need.

Neverfail for Microsoft SQL Server proactively monitors your SQL Server database application, including all system and data tables, looking for data changes. It then reconfigures itself accordingly to ensure that all database changes are included in its replication set. In case of failover, these database changes will be fully restored.

Neverfail for Microsoft SQL Server also proactively monitors the health of your entire SQL Server environment, including physical server hardware, network infrastructure and operating system. If any problem occurs, Neverfail can take a variety of preemptive, corrective actions without resorting to a full system failover. If required, a graceful switchover to your secondary server can occur automatically, ensuring SQL Server high availability, SQL Server disaster recovery and SQL Server continuous data protection.

Designed for LAN and WAN environments

Flexible Neverfail architecture can be implemented in both LAN and WAN environments. And, where bandwidth or network utilization is an issue or needs to be reduced, the Neverfail Low Bandwidth Module — a data compression tool — is available to optimize and reduce the amount of data that is transmitted between the two SQL servers.

Protection for a wide range of applications

Award-winning Neverfail products and plug-ins support mission-critical Windows®-based applications, including Microsoft® Exchange, SharePoint®, SQL Server, File Server, and IIS, as well as RIM BlackBerry®, IBM® Lotus® Domino® VMware VirtualCenter and Captaris®RightFax.

An added layer of powerful functionality is offered through our optional Low Bandwidth Module — a data compression tool, and all plug-ins include our Data Rollback Module.

Neverfail even provides out-of-the-box support for auxiliary applications such as anti-virus, archiving, back-up, anti-spam, and fax products. Please visit the Neverfail plug-ins page for a complete listing of all supported products.

Point-in-time data rollback

Neverfail's Data Rollback Module complements our core technology by providing a simple and swift application restart from earlier points in time. This ensures data restoration and the ability to regain data integrity quickly and efficiently after data corruption has occurred. Neverfail Data Rollback Module runs directly on top of Neverfail Heartbeat and utilizes the Microsoft® Volume Shadow Copy Service (VSS) technology to provide an efficient application/data restoration and retrieval mechanism.
