Check the vDR Appliance does not have the disk attached itself still, shutdown the VDR appliance, and remove the disk.

You seem to have snapshots building up on this VM

Previosuly I can do snapshot to almost all the VM's in that ESXi4.1

But One VM (sbs2008) dosen't do the Snapshot (the One I have attached the screenshut)
I get error message
A general system error occured: Protocol error from vmx
and
Cannot complete the operation because the file ot folder [datastore]sbs200/sbs2008.vmx already exists

the above is the error I get if I try to do a snapshut from the vClient



if the VDR tries to do the backup then the error is
Failed to create snapshut for sbs2008, error -3941 (create snapshut failed)

But you must do it this wayu

1. Uninstall Tools.
2. Reboot VM
3. Re-install Tools
4. Reboot
5. Try Snapshot with Quiece Option, and Untick Memory (that's the same Snapshot which VDR tries)

Did you check the VDR appliance, to see if there are disks attached to it, that belong to this VM?

This is your issue

To resolve this issue, locate and manually remove the -delta.vmdk file that does not have an associated descriptor file.

    Connect to the ESX or ESXi host using the vSphere Client.
    Locate the affected virtual machine in the Inventory.
    Determine which datastore(s) the virtual machine is stored on.
    Open the Datastore Browser.
    Navigate to the working directory containing the Virtual Machine configuration files. For more information, see Creating snapshots in a different location than default virtual machine directory (1002929).
    Confirm that remnant redolog delta.vmdk files from previous snapshots exist. For example:

        VM is currently pointed to vmname-000001.vmdk
        vmname-000001.vmdk 's parent is the VM base disk, vmname.vmdk
        A file named vmname-000002-delta.vmdk exists in the VM directory.
        The .vmx file does not reference the file named vmname-000002-delta.vmdk.
        The .vmsd file does not reference the file named vmname-000002-delta.vmdk.


    Rename or move the remnant file aside. For example, move the file vmname-000002-delta.vmdk into a backup directory.
    Retry the Create Snapshot operation, it should complete successfully.

Did you check VDR Appliance?

Personally, I would use VMware Converter or the Clone option in vCenter to create a new VM, without this issue, because all these files are incorrect.

This would create a new VM with all these incorrect snapshot files.

This is the VMware recommended approach when in "snapshot hell".

Currently the VDR has 2 attached one is the OS itself and the Other is another VM getting Backup Now

so the VM with the issues is not attached?

You could try the following:

move all the ctk files and vmsn files to another folder.
