Abstract
A system and method for capturing a point-in-time image of a file system utilized within a data storage system employing logical volumes mapped across physical volumes. The point-in-time backup process begins with receipt of a file system backup request. In response to receiving the file system backup request, buffered file system data is written or flushed to the logical volumes. Specifically, in response to the file system backup request, buffered user data is written to the logical volumes, buffered meta data associated with the buffered user data is written to a file system backup log within the logical volumes, and the buffered meta data is written to the logical volumes. A disk copy of the designated physical volumes is initiated in response to the writing of the buffered file system data to the logical volumes.
