I have a server sitting on a Hyper-V Cluster. I have a VeeaM job which points to the cluster to do it's backup. However, VeeaM constantly fails with:
Error: Job failed ('Failed to get the disk information. Failed to open attachment '\\fileserver\disk.vhdx'. Error: 'The process cannot access the file because it is being used by another process.'.'). Error code: '32774'. Failed to get information about vhd disk '\\fileserver\disk.vhdx'. Failed to get shared disks extents Failed to enumerate VM disks. Failed to get informa
Other VM's within the Cluster backup fine, regardless of if they're 2012, 2012 R2 or 2016.
So I create a new job, and directly backup the VM (selecting the actual VM, not via the Cluster object). This runs without error.
Within the cluster, there are around 5 VM's exhibiting this behaviour.
What do I need to do to get VeeaM to process these VM's correctly?
