Abstract: A method is integrated into the local operating system of a test machine. The disclosed technique preferably uses a master copy of one or more data objects from a first location to create virtual data objects (e.g., files or folders) that appear to be part of a file system mounted to a test machine in a second location. This disclosure describes a “projection” method and computer program that enables access to a destination object at a target location immediately upon initiation of a copy command at a source location while a copy operation is carried out in a background manner.

Abstract: A data management system (DMS) includes a continuous real-time object store that captures all real-time activities, with associated object metadata information. The DMS is capable of reintroducing any point-in-time view of data ranging from a granular object to an entire file system. A set of algorithms (for creation of a file or directory, modification of a file or directory, deletion of a file or directory, and relocation/renaming of a file or directory) are used to generate and maintain a file system history in the DMS and to ensure that a latest version of a directory always refers to a latest version of its children until the directory changed. Any point-in-time recovery is implemented using the file system history in one of various ways to provide strong individual file integrity, exact point-in-time crash consistency, and/or recovery of last version of all files in the file system.
