I don't know if VSS has this capability, but essentially if it can temporarily quiesce a device like a data base does for "warm standby" then a snapshot should work. This would be a very simple Windows side script/batch:
1) Q-Disk 2) Remote trigger snapshot 3) Un Q-Disk I have no idea where to even begin researching VSS unfortunately...

VSS is used at the file-system level on either NTFS partitions or over CIFS. -J VSS integration with block protocols is most definitely possible. It just requires *intelligent* software running on the host side. That intelligence would likely need to come from Sun directly in the case of windows on raw hardware as I don't know of any third party apps that work universally with any storage system. --Tim
