File Restore Methods

Guest files and folders can be restored to a physical client or to a virtual machine (VM) in the following ways:

Note: To restore virtual machine files and folders when the total restore size is larger than 100 GB or has more than 50,000 files, use an agent installed in the destination client or virtual machine. For the fastest recovery time and the least space required for extent caching, use Live File Recovery with an agent in the guest.

General Requirements

  • To recover larger files or in other cases where you cannot restore a file, restore the complete virtual machine or the disk that contains the file.
  • If a backup set contains some subclients configured for regular backup and other subclients configured for IntelliSnap backup, initiate browse and restore operations from each subclient rather than from the backup set.
  • If a virtual machine has a GPT partition, you can restore files from a streaming backup, IntelliSnap backup, or backup copy.
  • When you restore folders from a backup that was performed using the Collect File Details option, folder permissions are not restored.
  • For Windows guest VMs:
    • Restores of symbolic link files and hard link files are not supported.
    • For files stored on Windows Storage Spaces, you can perform a live browse to view and restore guest files and folders, with the following considerations:
      • The VSA proxy or MediaAgent that is used for the live browse must be running on Windows Server 2012 or later.
      • The MediaAgent that is used for the live browse cannot be part of a clustered environment.
      • You cannot simultaneously browse two cloned VMs that use the same storage space information.
    • You can restore files from NTFS file systems with the following limitations:
      • The formatted cluster size (allocation unit) must be 1024 or greater.
      • You cannot restore any archived (stubbed) files and folders.
      • Use Live File Recovery to restore files that have been dehydrated by Windows deduplication.
  • For Linux guest VMs:
    • From a backup that was performed using the Collect File Details option, you cannot restore any file that has zero bytes, hard links, or symbolic links.

      To restore these files, deploy a File Recovery Enabler for Linux (FREL) and use Live File Recovery.
