Error: "No Valid Partition found" during File level restore

Last Updated: May 31, 2017 09:01AM CEST


During a File level restore, you encounter the error "No Valid Partitions" when selecting your Virtual Disk.




Note:  Accidentally selecting a blank Virtual Disk from the drop-down list will result in this error. The below information assumes that you are indeed selecting a Virtual Disk that contains data.

Restore a clone of the VM and boot it up to retrieve the required files from the cloned VM.  By default Altaro VM Backup will disable the restored VM's NIC so it will not have any affect on your production environment.

Instructions to restore a clone of your VM can be found here: 


This error indicates that the guest partition you are trying to restore from does not meet the requirements for file level restore and thus can only be restored as a VM clone. 

You may encounter this error if attempting a File Level Restore from:
  • a Linux guest VM (ext3/ext4 file system),
  • a guest VM with a ReFS formatted partition
  • a guest VM with Windows Deduplication enabled
  • a guest VM with it's partition formatted as 'Dynamic'.and not 'Basic'
  • a guest VM with files encrypted or compressed at guest OS (VM) level
