Volume Shadow Copy Service – SWPRV.DLL

Swprv.dll installs with Microsoft's Shadow Volume Copy Service. If you run Windows XP, Windows 2003, or Vista, this file is part of your Windows operating system. The Volume Shadow Copy Service provides the backup infrastructure for the Microsoft Windows operating systems, as well as a mechanism for creating consistent point-in-time copies of data known as shadow copies.

The Volume Shadow Copy Service can produce consistent shadow copies by coordinating with business applications, file-system services, backup applications, fast-recovery solutions, and storage hardware.
