Configure the VSS shadow copy directory depth (for Hyper-V over SMB shares)

Contributors netapp-aherbin

Optionally, you can configure the maximum depth of directories within SMB shares on which to create shadow copies. This parameter is useful if you want to manually control the maximum level of subdirectories on which ONTAP should create shadow copies.

What you'll need

The VSS shadow copy feature must be enabled.

About this task

The default is to create shadow copies for a maximum of five subdirectories. If the value is set to 0, ONTAP creates shadow copies for all subdirectories.

Note

Although you can specify that the shadow copy set directory depth include more than five subdirectories or all subdirectories, there is a Microsoft requirement that shadow copy set creation must be completed within 60 seconds. Shadow copy set creation fails if it cannot be completed within this time. The shadow copy directory depth you choose must not cause the creation time to exceed the time limit.
Steps

  1. Set the privilege level to advanced:

    set -privilege advanced

  2. Set the VSS shadow copy directory depth to the desired level:

    vserver cifs options modify -vserver vserver_name -shadowcopy-dir-depth integer

    vserver cifs options modify -vserver vs1 -shadowcopy-dir-depth 6

  3. Return to the admin privilege level:

    set -privilege admin
