You have a Windows Server 2012 (or later) with Data Deduplication enabled for its NTFS volumes. You have created a backup of this server and want to restore some files from this backup.
You can recover individual files from such volumes after restoring the entire machine on disk level. There are several ways to do that:
1) If you have Agent for VMware or Agent for Hyper-V, run the backup as a virtual machine and copy files from the VM. Learn how to use the Run as VM feature in this topic.
2) Use any virtualization platform (e.g. Oracle Virtual Box), create an empty VM and recover the entire machine backup to it using Bootable Media. See this topic for instructions. After recovery is completed, copy the necessary files from the VM.
3) Recover the backup to a spare physical machine
