May 03, 2004, 12:00 AM — Windows Server 2003 is positioned to be a viable operating system in the
network attached storage (NAS) marketplace.
Last week we looked at some of the advantages of Microsoft's new version
of its Windows Server 2003 operating system called Windows Storage
Server 2003 (WSS). This week begin looking at some of the technical
details of this new version of its OS.
One of the best technical features of WSS is the Volume Shadow Copy
Service (VSS), which is an infrastructure that makes it possible to take
point in time shadow copies of data from one or more volumes. This is
similar to the snapshot technology that many Storage Area Network (SAN)
vendors utilize. There are many benefits to shadow copies. First, you
are able to create a shadow copy in seconds, instead of hours. Second,
there is no impact on network or server performance during the shadow
creation. Third, you are able to make copies of files that are open by
applications, making it possible to backup applications that are used in
Similar to the benefits of creating the shadow copies are the benefits
to restoring data that was created using VSS. Restores now only take
minutes, and can be accessed instantly. The restore can be stored in a
new location, or over the existing data depending upon your needs.
Additionally, administrators are not the only people to benefit from the
fast restore functionality enabled by VSS. Administrators have the
ability to enable Shadow Copy for Shared Folders (SCSF), which allows
users to restore previous version of files on their own without placing
costly trouble-tickets or contacting help desks and system
administrators - thus reducing overall support costs.
