Hallo Carlos,

my fault, I was not very precise. Saveset is of course APPLICATIONS:\Microsoft Hyper-V. But one of the VMs has a missing VHD.

Bernd

Hello Bernd,

To backup Hyper-V you need to use the correct save set.

Please run the following command to retrieve the valid save sets, in Hyper-V server:

nsrsnap_vss_save -v -?

The save set to backup Hyper-V guests, .vdh's and configuration file should be:

APPLICATIONS:\Microsoft Hyper-V

And valid save sets would be something like this:

APPLICATIONS:\Microsoft Hyper-V

APPLICATIONS:\Microsoft Hyper-V\Initial Store

APPLICATIONS:\Microsoft Hyper-V\child_partition_name_1

APPLICATIONS:\Microsoft Hyper-V\child_partition_name_2

Thank you.

Carlos.

Hi Bernd,

As explained before, if you want to skip one of the VM's for any reason, then you need to change the save sets.

Please note that the variable " NSR_IGNORE_MISSING_SYSTEM_FILES=yes" is intended for skipping files that were removing during a piece of software uninstallaiton, but there are some entries left in the registry, it's not really intended for this kind of operations (skip files needed to be backed up during application backup but those files, as .vhd in this case, are not there).

So my suiggestion regarding the save sets would be as follows:

Based on the output of running the command nsrsnap_vss_save -v -? the save sets I would be adding would be:

Imagine this is the output of the command:

APPLICATIONS:\Microsoft Hyper-V\Initial Store

APPLICATIONS:\Microsoft Hyper-V\child_partition_name_1

APPLICATIONS:\Microsoft Hyper-V\child_partition_name_2

And the .vhd of vm1 is missing, then you would be adding these save sets:

APPLICATIONS:\Microsoft Hyper-V\Initial Store

APPLICATIONS:\Microsoft Hyper-V\child_partition_name_2

Thank you.

Carlos.
