Failover Cluster Support

In this article

    You can use Veeam Agent for Microsoft Windows operating in the managed mode (within the Veeam Agent management scenario) to protect data processed by a failover cluster. Veeam Agent supports Windows Server Failover Clusters running on any of the supported Microsoft Windows Server OS versions. To learn the full list of versions, see System Requirements.

    Veeam Agent supports data backup and restore for the following types of clusters:

    • Windows File Server Failover Clusters
    • Windows Server Failover Clusters that run the following applications:
    • Microsoft SQL Server 2008 SP4 or later

    Keep in mind that SQL Server Failover Cluster Instances and AlwaysOn Availability Groups are supported only for Microsoft SQL Server 2012 or later. For details about AlwaysOn Availability Groups, see Backup of AlwaysOn Availability Groups.

    • Microsoft Exchange Server 2010 or later

    Microsoft Exchange Database Availability Groups (DAGs) are supported. For details, see Backup of Database Availability Groups.

    Limitations for Failover Cluster Support

    Failover cluster support in Veeam Agent for Microsoft Windows has the following limitations:

    • AlwaysOn Availability Groups based on SQL Server Failover Cluster Instances are not supported.
    • AlwaysOn Clusterless Availability Groups are not supported.
    • Distributed AlwaysOn Groups are not supported.

     

    Failover Cluster Support NOTE

    Veeam Backup & Replication does not support simultaneous processing of Microsoft SQL Server transaction logs on SQL Server clustered instances with identical names. The limitation applies to clustered instances of different failover clusters as well.

    For example, you configure two backup jobs that process transaction logs of different clusters whose SQL clustered instances have identical names. In case these backup jobs run simultaneously, transaction logs will be processed only by the backup job that started first. The second backup job will not process transaction logs.
