>
> Running {{ExportSnapshot}} with default parameters will copy the snapshot to
> a target location, and then use {{verifySnapshot}} to validate the integrity
> of the written snapshot. However, it is possible for the source snapshot to
> be invalid which leads to an invalid exported snapshot.
> We can validate the source snapshot before export.
> By default, we can validate the source snapshot unless the
> {{-no-target-verify}} parameter is set. We could also introduce a separate
> parameter for {{-no-source-verify}} if an operator wanted to validate the
> target but not validate the source for some reason, to provide some amount of
> backwards compatibility if that scenario is important.
