> Some Netapp and other storage units may automatically create copies of the
> contents of a volume on a schedule. For Netapp units, snapshot copies are
> stored under a _.snapshot_ directory on the volume. This directory may be
> accessible from the VM host. It is possible to configure the volume so that
> this directory is not displayed on hosts, however, this is not the default.
> Problems occur if the _.snapshot_ directory is accessible on the VM host
> because the VCL code may attempt to alter the files contained in it. As an
> example, if the code attempts to delete a VM for which a copy of its working
> directory was saved in a Netapp snapshot:
