Hotfix Available For Volume Shadow Copy Service Issues

This article describes an update that is available for the Microsoft Windows Server 2003 Volume Shadow Copy Service (VSS) feature. The update is dated July 19, 2005.

This update fixes the following issues:

• On a Windows Server 2003-based computer that has many shadow copies that are being used, the paged pool memory on the computer may become exhausted. This problem may occur when the shadow copy snapshots are of large volumes and when each volume contains many files. After you install the update, Microsoft Windows dismounts unused shadow copies when paged pool memory is low.

Note Windows remounts the dismounted shadow copies when a client accesses the shadow copy.

• In some scenarios, VSS does not maintain the shadow copy device name across the BreakSnapshotSet() API.

• Sometimes, when you delete multiple hardware shadow copy sets at the same time, an error occurs in the DeleteSnapshotSet() API, and the delete operation fails.

• The update removes a stock keeping unit (SKU) block that let you create and import transportable shadow copies only on Microsoft Windows Server 2003, Enterprise Edition and on versions of Microsoft Windows Server 2003, Datacenter Edition. After you install the update, you can create and import transportable shadow copies on all Windows Server 2003 operating systems.”
