Guest Processing

In this article

    If you back up or replicate running VMs, you can enable guest processing options. Guest processing options are advanced tasks that require Veeam Backup & Replication to communicate with the VM guest OS. Veeam Backup & Replication offers the following guest processing options:

    • Application-aware processing. You can create transactionally consistent backups and replicas of VMs that run Microsoft Active Directory, Microsoft Exchange, Microsoft SharePoint, Microsoft SQL Server or Oracle Database. The transactionally consistent backup guarantees proper recovery of these applications without data loss. For information on system requirements for the applications, see System Requirements.

    VM guest file system indexing is optional. If you do not enable this option in the backup job settings, you will still be able to perform 1-click restore from the backup created with such backup job. For more information, see the Preparing for File Browsing and Searching section in the Enterprise Manager User Guide.

    Note

    If you plan to use Kerberos authentication for guest OS processing, mind the following:

    • Local accounts do not support Kerberos authentication. To authenticate with Microsoft Windows guest OS using Kerberos, specify an Active Directory account.
    • Networkless application-aware guest processing through VMware VIX/vSphere Web Services is not supported for VMs with guest OS where NTLM is restricted.
    • Backup infrastructure components (backup server, repositories, backup proxies, guest interaction proxies, and other components) must correctly resolve FQDNs of guest operating systems.
    • To process workloads where Kerberos is used, NTLM must be allowed in the backup infrastructure components. For details, see Kerberos Authentication for Guest OS Processing.
