Review comment:
One workaround I already have in place, though, is the following (currently
only supported on XenServer): You can pass in a parameter when taking the
volume snapshot that tells us to put the volume snapshot on secondary storage
instead of keeping it on primary storage. If, however, you have already created
the snapshot on primary storage, then you'd need to create a volume from it and
then snapshot that volume to secondary storage.
