NetVault Plug-in for Hyper-V 10.5 - Release Notes

Resolved issues

Previous Next


Restored support for file-level backups and restores. To complete a file-level backup, process an image-level backup with the new Enable indexing for File Level Recovery option selected. Indexing lets you perform a subsequent file-level restore.
Corrected an issue that prevented a Windows Server® 2008 R2-based Hyper-V cluster from locating and backing up a VM on a remote host.

Known issues

Previous Next


The Percentage Complete progress bar in the Monitor Job page is not currently populated with the appropriate progress of the job.
The plug-in does not support Hyper-V® installations that have two or more VMs that share identical names.
If you are using the Hyper-V® Role for Windows Server® 2008 R2 with Simplified Chinese, French, German, and Korean, permission is not correctly granted during the VM recovery, which renders the VM unrecognizable by Hyper-V® Manager. To grant permission to the restored files manually, run the following command on all restored files, including .vhd, .avhd, .xml, .bin, and .vsv, for the VM.
icacls <restore_file> /grant "NT VIRTUAL MACHINE/<VMID>":F /l
If you are using the Hyper-V Role for Windows Server 2012 or 2012 R2 with a localized version of the NetVault Backup Server or Client, or both, manually remove the VM before initiating image-level recovery. Otherwise, recovery fails even though files are correctly restored to the Working Directory.
If your environment uses Windows Server 2008 R2 as the Hyper-V Server and you use the Rename feature during a restore, the recovery does not include network adapters that the VM backup included. After recovery is finished, use Hyper-V Manager to add the network adapters for the VM.
If you perform a file-level restore, do not use the Rename option in the Actions list for the VM node. Although the option is enabled, the plug-in ignores the Rename field and the restore completes with warnings.
Workaround: To recover sparse files, perform an image-level recovery.
Workaround: To recover sparse files from backups taken using version 1.7, perform an image-level recovery.
If your environment uses Windows Server 2012 or 2012 R2 as the Hyper-V Server and you use the default Virtual Hard Disks directory to store the VM’s virtual disks, make sure that all the VM’s disks reside in the same directory. If any disks reside elsewhere, recovery fails. This requirement is a limitation of the Hyper-V Import-VM cmdlet used in Windows PowerShell® to create the VM during recovery.
Move all VHD or VHDX files from the Virtual Hard Disks directory to another directory, and delete the Virtual Hard Disks directory.
Move all VHD or VHDX files to the Virtual Hard Disks directory.
In Hyper-V Manager, use Action > Import Virtual Machine.
In PowerShell, started with elevated permissions, run: Import-VM -Register -Path <pathToVMsXMLconfigFile>
Workaround: Power down the VM, and run the backup job again.
If your environment uses Dell DR Series appliance or EMC® Data Domain® Boost (DD Boost™) as the backup target, you should see less impact on performance than with other backup targets. These targets use source-side deduplication technology, which handles whitespace more efficiently.
Workaround: There is no workaround for this issue. If you use dynamically expanding disks and performance is affected, Dell recommends that you use Plug‑in for Hyper‑V- 10.0.1.
