About this release

Rapid Recovery software delivers fast backups with verified recovery for your VMs and physical servers, on-premises or remote. Rapid Recovery is software built for IT professionals who need a powerful, affordable, and easy-to-use backup, replication, and recovery solution that provides protection for servers and business-critical applications like Microsoft SQL Server, Oracle Database, Microsoft Exchange, and Microsoft SharePoint. Using Rapid Recovery, you can continuously back up and protect all your critical data and applications from a single web-based management console.

Rapid Recovery 6.6 is a minor release, with enhanced features and functionality. See New features and Enhancements for details.

NOTE: For more information about how major, minor, and maintenance releases are differentiated, see Rapid Recovery release designations.

Some features, previously integrated software tools, or platforms are no longer supported. For more information on these items, see Deprecated features.

As a minor release, defect fixes and known issues listed in this document are not cumulative.

For information relevant for any other release, please see the edition of release notes specific to that release on the Quest technical documentation website.

NOTE: In this release of Rapid Recovery, Quest removed the Beta label from the Azure repository feature. Quest discourages using an Azure repository for storing original recovery points and recommends using it only for storing replicated recovery points. For more information, see "Replication with Rapid Recovery" in the Rapid Recovery 6.6 User Guide.

NOTE: Currently, the Rapid Recovery Core Console lets you connect to an Azure repository only from the source Core that replicates to it, and does not support the Connect to Existing feature. For more information, see

Limited support: Quest Data Protection Support may attempt to answer questions on other versions of our products, provided resources are available.
