Unlike agent-based file restores (which require an operating system to be running inside the VM), flat file restore works at the hypervisor or backup storage layer. It reads the raw data blocks of the VM’s virtual disk, parses the file system structure (NTFS, ext4, etc.), and extracts only the blocks belonging to the requested file.
When a critical virtual machine (VM) fails or its configuration files vanish, the file becomes your most valuable asset. While the small .vmdk file is just a text descriptor, the -flat.vmdk contains the actual raw data of your virtual disk.
If you lose the descriptor but still have the flat file, your data is intact, but the VM cannot "see" it until the descriptor is recreated. 2. Method 1: Rebuilding the VM Descriptor (Manual Restore) vmware flat file restore
: Run ls -l [VMNAME]-flat.vmdk and record the exact size in bytes.
3. Method 2: Accessing Files Without Booting (Granular Recovery) Unlike agent-based file restores (which require an operating
By following these steps and best practices, you can successfully perform a VMware flat file restore and recover your data in case of a disaster.
: Delete the temp-flat.vmdk and rename temp.vmdk to match your original disk name. While the small
