Guest Processing

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 running applications that support Microsoft VSS. Application-aware processing guarantees that you can restore VMs without data loss.
  • Pre-freeze and post-thaw scripts. You can use pre-freeze and post-thaw scripts to quiesce VMs running applications that do not support Microsoft VSS.
  • Transaction log truncation. You can set the backup or replication job to truncate transaction logs on the VM guest OS after the VM is successfully processed.
  • Transaction logs backup for Microsoft SQL Server and Oracle. You can set up the backup job to back up transaction logs from Microsoft SQL Server and Oracle VMs.
  • VM guest file system indexing. You can set up the backup job to create a catalog of files and folders on the VM guest OS. The catalog lets you search for VM guest OS files and 1-click restore in Veeam Backup Enterprise Manager.

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.
