摘要： Restore software executing in a computer system may invoke a snapshot of a target volume before restoring a plurality of files from a backup image to the target volume. If the restore operation fails before all the files are restored to the target volume then the restore software may use the snapshot to return one or more of the files to their original states as they existed before the restore operation was initiated.
摘要翻译：在计算机系统中执行的还原软件可以在将多个文件从备份映像还原到目标卷之前调用目标卷的快照。如果在所有文件恢复到目标卷之前还原操作失败，则还原软件可能会使用快照将一个或多个文件返回到原始状态，因为它们在还原操作启动之前存在。

摘要： Techniques for virtualizing data are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for virtualizing data comprising identifying source data to be virtualized, intercepting an input/output (i/o) request to the source data, determining whether the input/output request is a read request or a write request, in the event the input/output request is a write request, storing one or more changes contained in the write request, and in the event the input/output request is a read request, determining whether a portion of data requested has been modified and responding to the read request. Responding to the read request may comprise providing stored data in the event a portion of the data requested has been modified, and utilizing source data in the event the data requested is unmodified.

摘要： A method and apparatus for performing file-level restoration from a block-based backup file stored on a sequential storage device is described. In one embodiment, a method of processing a backup file to perform file-level restoration from a sequential storage device comprises generating extent information, wherein the extent information pertains to at least one file system object associated with a backup file, wherein the backup file is to be stored on a sequential storage device, wherein the backup file is block-based and processing a backup catalog, wherein the backup catalog indicates locations of various portions of the extent information and is used to restore a file system object.

摘要： A method and apparatus for creating and using a snapshot in data backup and/or other data services. The method creates snapshot(s) of volume(s) using a select set of Snapshot Providers, transports the snapshots to a server for processing and processes the snapshots. Processing may include creating a backup, data mining the snapshot, and the like.
