Although the default behavior of SnapManager for Hyper-V is to cause backups containing virtual machines that are in the saved state to shut down or fail, you can perform a saved-state backup by moving the virtual machines to a dataset that has a policy that allows saved-state backups.
You can also create or edit your dataset policy to allow a saved-state virtual machine backup. If you choose this option, SnapManager for Hyper-V does not cause the backup to fail when the Hyper-V VSS writer backs up the virtual machine using the saved state or performs an offline backup of the virtual machine. However, performing a saved-state or offline backup can cause downtime.
