Notes on Hyper-V policy attributes when you use the NetBackup commands

Note the following for the policy attributes:

  • The -hyperv_server option specifies the Hyper-V host, Hyper-V cluster, or SCVMM server that contains the VMs to back up.

  • The option -snapshot_method "HV" specifies the WMI snapshot method for VMs on Hyper-V hosts that run Windows 2016 or later. (-snapshot_method "Hyper-V_v2" specifies the VSS method, which does not support block-level incremental backup or Accelerator.)

  • The option -blkincr: 1 enables block-level incremental backup (BLIB).

  • The option -use_accelerator: 1 enables Accelerator. (This option also enables BLIB.)

  • The -snapshot_method_args option is a comma-delimited list of keywords that define the Hyper-V snapshot and policy.

    The available keywords and values for -snapshot_method_args are described in a separate topic:

    See The bpplinfo options for Hyper-V policies.
