Abstract: Maintenance of plural active file systems (100), wherein each of the active file systems initially access data (120) with another of the active file systems, and wherein changes made to each of the active file systems are not reflected in other active file systems. When a second active file system is created based on a first active file system, the first active file system and the second active file system initially share data. When changes are made to the first active file system, modified data is recorded in the first active file system in a location that is not shared with the second active file system in a location that is not shared with the second active file system. When changes are made to the second active file system, modified data is recorded in the second active file system in a location that is not shared with the first active file system. Also, creation of the plural active file systems.

Abstract translation: 维护多个活动文件系统（100），其中每个活动文件系统最初与另一个活动文件系统访问数据（120），并且其中对每个活动文件系统所做的更改不会反映在其他活动文件系统 。 当基于第一活动文件系统创建第二活动文件系统时，第一活动文件系统和第二活动文件系统最初共享数据。 当对第一活动文件系统进行改变时，修改的数据在不与第二活动文件系统共享的位置处不与第二活动文件系统共享的位置记录在第一活动文件系统中。 当对第二活动文件系统进行改变时，修改的数据被记录在不与第一活动文件系统共享的位置的第二活动文件系统中。 另外，创建多个活动文件系统。

Abstract: A system and method enables a storage system to support multiple volume type simultaneously. A volume type field is contained within a file system information block that permits the storage system to determine the type of volume of a particular volume associated therewith. The storage operating system may then interpret various on-disk data structures in accordance with the appropriate volume type.

Abstract: The invention provides techniques for duplicating all or part of a file system while maintaining consistent copies of the file system. A preferred embodiment reads data from the source file system (mapped according to a first storage block arrangement) creates an image stream and writes this data onto the destination file system (in accordance with a second storage block arrangement). Thus, the invention allows an image transfer between file systems that have dissimilar characteristics. An intermediate storage medium can be used to store or transmit the data read from the source file system before writing the data to the destination file system. (For example, the intermediate storage medium can include a magnetic tape or other archival device, or a network). Another aspect of the invention writes the data to the intermediate storage medium using a normalized or implied block list. The information is read from the intermediate storage medium using normalized or implied block list and written to the destination file system according to the second storage block arrangement. Another aspect of the invention is that the invention determines a first set of block numbers (BNs), determines where the blocks referenced by the these BNs are to be stored, and updates the BNs accordingly.

Abstract: The invention provides a method and system for duplicating all or part of a file system while maintaining consistent copies of the file system. The file server maintains a set of snapshots, each indicating a set of storage blocks making up a consistent copy of the file system as it was at a known time. Each snapshot can be used for a purpose other than maintaining the coherency of the file system, such as duplicating or transferring a backup copy of the file system to a destination storage medium. In a preferred embodiment, the snapshots can be manipulated to identify sets of storage blocks in the file system for incremental backup or copying, or to provide a file system backup that is both complete and relatively inexpensive.
