Hyper-V hosted vm gets backed up in Saved Sate RRS feed

  • Question

  • Hello,

    I am trying to get help on an issue with a VM hosted on a hyper-v.

    The machine is getting backed up and the backup is working fine as well. The main concern is that during the snapshot process the machine goes into 'Saved State" for about 5 minutes. This is not what we expect the backup application to do as the VM is a Server 2003 SP3 X64 and is used under production environment. 

    I have checked all possible posts and blogs and found a link which list why a machine would be backed up in Saved State.

    • Backup (Volume Snapshot) Integration Service is disabled or not installed. 
    • VM has one or more dynamic disks. 
    • VM has one or more non-NTFS based volumes. 
    • The VM Cluster Resource Group in a cluster setup is offline. 
    • VM is not in a running state. 
    • A ShadowStorage assignment of a volume inside the VM is explicitly set to a different volume other than it

    None of them is true for the affected VM.

    I checked the command output "vssadmin list writers"

    I want to change the configuration of the affected VM and want to make change to the highlighted entry. Notice that the affected machine "IS-AASIS-RPT" is configured to be backed up in saved state.

    Please let me know from which file is this configuration gathered from and how can we make sure that VM is backed up using Child Partition Snapshot.

    Note: All the components of Hyper-v Integration services are active and updated. Uninstallation and reinstallation has been already attempted.

    The registry fix "adding a key SYSTEM RESTORE" for Server 2012 is not applicable for Server 2003.

    Thanks in advance.
