Data Rollback Module

Neverfail Data Rollback Module ensures continuous data protection

If a failover occurs, data restoration is ensured by enabling a simple, swift application restart from earlier points in time when the data was still consistent, accurate and usable.

Neverfail Data Rollback 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. By taking shadow copies of a secondary, passive server, Neverfail avoids the typical “freezing” of an application that VSS would normally incur on a production system, and thus permits more frequent shadowing than in a single-server topology.

More frequent shadowing means greater granularity

...up to 512 snapshots can be stored at any one time in an ultra-efficient format that only needs to keep track of differences between snapshots. When a rollback is required, Neverfail's unique knowledge of the application environment — including which application files and registry settings require rollback protection — permits efficient restoration of only the required application data from shadow copies, rather than an entire volume.

Neverfail's Data Rollback Module is incorporated directly into our standard management console...

...providing a single interface for all of your high-availability and disaster recovery needs. Administrators can use the interface to customize their own snapshot schedules, allowing them to decide for how long each snapshot should be saved. Then if data corruption does occur, administrators can roll back to any of these snapshot points with the simple click of a button.

Neverfail Data Rollback Module solutions:

• Recover data from a physical or logical corruption to a consistent point in time
• Provide either manual or automatic switchback following a failover, with automatic resynchronization between primary and secondary servers
• Integrate with Neverfail high availability and disaster recovery solutions to provide complete application availability, no matter the cause or source of corruption
• Leverage Microsoft® Volume Shadow Copy Service (VSS) technology to ensure the highest level of compatibility across your Microsoft environment
• Eliminate all overhead associated with taking snapshots against your production server
• Reduce required storage significantly by only capturing the differences between your data and allowing consolidation of older data images
• Neverfail solutions also ensure that users stay connected to applications during IT activities requiring planned downtime, such as migrations, upgrades, maintenance, and virtualization.
