Data Backup Software and Service

Microsoft offers a version of Windows NT that is sometimes referred to as "Embedded NT" and more often as the Server Appliance Kit, or SAK. This offering is based on Windows 2000, which does not have a volume shadow copy service. For the benefit of original equipment manufacturers that use the SAK to build NAS devices, Microsoft has licensed a snapshot solution and included it in the SAK. This snapshot product is the Persistent Storage Manager (PSM) from Columbia Data Products. This section provides a quick overview of PSM architecture and functionality.
