Enabling or Disabling Backups with Granular Recovery
Perform a backup with granular recovery to capture file and folder metadata for a virtual machine. By default, granular recovery is enabled for streaming backups and disabled for IntelliSnap backups. You can disable granular recovery if you do not want to collect metadata during backups.
If granular recovery is not enabled for a backup, file and folder information can still be browsed (Live Browse) and restored (Live File Recovery). These options add time to browse and restore operations. Live File Recovery is not available for backups that used granular recovery.
If granular recovery is enabled but some file information could not be read (for example, ext4 data for a Linux VM), partial metadata is collected during the backup, and you can only browse files and folders for which metadata was successfully captured. To enable Live File Recovery to be used in such situations, you can add the bAllowPartialVMMetadata additional setting to the Virtual Server Agent proxy and set the value to false. With that setting, partial metadata for a virtual machine is discarded, enabling Live File Recovery to be used for browse and restore operations. For steps, see Add or Modify an Additional Setting.
- For backups that use a Unix MediaAgent, the index for the Unix MediaAgent is copied to the Windows MediaAgent selected for the browse and restore. This enables all volumes, files, and folders to be displayed when browsing a virtual machine.
- To support file and folder restores, the Index Cache must be on an NTFS disk.
- Metadata collection using the Enable Granular Recovery option is not supported for IntelliSnap backups of Linux virtual machines. To recover files and folders from IntelliSnap backups of Linux virtual machines, use Live File Recovery.
Disabling Granular Recovery for a Subclient
Perform the following steps to enable or disable the granular recovery option for a subclient:
- From the CommCell Browser, navigate to Client Computers > virtualization_client > Virtual Server > VMware > backup_set.
- Right click the subclient and select Backup.
- Select the Backup Type.
- Click Advanced.
- In the Data tab of the Advanced Backup Options dialog box, clear the Enable Granular Recovery check box to skip metadata collection.
- Click OK to save the advanced settings.
- Click OK to start the backup.
