DPM 2012 R2 Bug: Unable to backup a VM with the same name as an old VM RRS feed

  • Question

  • Scenario:

    1. You have a VM called "Virtual Machine 1" running on a Windows Server 2012 R2 Hyper-V cluster and you backup this virtual machine using DPM 2012 R2.
    2. You remove "Virtual Machine 1" from DPM, selecting delete replicas and expire all tape backups, and then delete the VM from the cluster as it is no longer required.
    3. Later you create a new virtual machine called "Virtual Machine 1" on the same cluster.  You attempt to backup the VM with DPM however when attempting to add the VM to a protection group you get the error "DPM cannot access the path \Online\Virtual Machine 1 because part of the path has been deleted or renamed.  Check the path and enter it again".  Refreshing the data source/clearing the cache doesn't help

    The only solution I could find that worked was to delete the data source record in DPMDB..tbl_IM_DataSource for the virtual machine.  This also required deleting records that referenced the DataSourceId in other tables.
