File Restore Methods
Guest files and folders can be restored to a physical client or to a virtual machine (VM) in the following ways:
- Guest Agent Restores
- Agentless Restores
- Live File Recovery
- Restores from backups made using a UNIX MediaAgent
Note:
- For the fastest recovery time and the least space required for extent caching, use Live File Recovery with a restore-only file system agent in the guest.
- You can use agentless file recovery when the total restore size is less than 10 GB and you are restoring fewer than 10,000 files.
- To restore virtual machine files and folders when the total restore size is larger than 10 GB or has more than 10,000 files, use a restore-only file system agent installed in the destination client or virtual machine.
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.
- 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.
