摘要： One aspect of the present invention provides an operation for recovering lost space and maintaining data consistency in a storage environment by providing a two-way orphan reconciliation method for extremely large file systems, such as a Hierarchical Storage Management (HSM) system which manages billions of files. This highly scalable and parallelizable orphan identification process may be used in a HSM controlled environment to enable the execution of a two-way file orphan check. In one embodiment, this orphan check identifies file system client orphans and server object orphans in a single pass by comparing a queue containing a list of migrated files on a storage repository server with a queue containing a list of stub files on a file system. If the queue elements do not match, a file system orphan or server object orphan can appropriately be identified.

摘要： A system, method and computer readable medium for providing a snapshot of a subset of a file system. A first snapshot of a first set of source files in a file system is generated. The first snapshot includes an inode corresponding to each source file in the first set of files. Stored in each inode is a first identifier associated with the first set of files and a second identifier associated with the time of the first snapshot. Next, a second snapshot of a second set of source files is taken. The second snapshot includes an inode corresponding to each source file in the second set of files. Stored in each inode are a first identifier and a second identifier. Subsequent snapshots are taken every first period and every second period for the first set of files and the second set of files, respectively.

摘要： Provided are a computer program product, system, and method for using a metadata image of a file system and archive instance to restore files in the file system. A metadata image of the file system for a point-in-time backup as of a point-in-time includes information on files and directories in the file system as of the point-in-time and an archive instance including a copy of database records in the backup database for the files in the point-in-time backup. A restore request is received. A file representation is created of each file to restore in the directory structure of the file system from the metadata image, wherein at least one of the created file representations indicates that the file is stored off-line and has an external identifier used to access information on the file in the database records in the archive instance for the point-in-time backup.

摘要： A technique for restoring file systems by applying full and incremental backups together while streaming them from multiple devices provides a faster system restore from a full backup where incremental backups must also be applied. A first storage device streams the full backup while at least one second storage device streams at least one incremental backup. As files are detected in the incremental backup, they are written instead of the corresponding file in the full backup. Incremental backups can be pre-merged to reduce their number to one less than a number of storage devices available to stream the backups, so that the full backup can be streamed along with the pre-merged incremental backup(s) to restore the file system.

摘要： A method is provided for managing the storage of a file that has been selected for migration from a first storage level within a file system to a second storage level. The method comprises copying each of one or more data blocks of the selected file that are stored in the first storage level at a physical disk address maintained in a corresponding reference of an inode for the selected file from the first storage level to the second storage level; maintaining a logical ditto address in each reference of an inode for each snapshot file in the file system that refers to one of the one or more data blocks of the selected file that were copied to the second storage level; and updating the file system to include a managed region for controlling access to the one or more data blocks through the inode for the selected file.

摘要： A system, method and computer readable medium for providing a file system snapshot with ditto address feature is disclosed. The method includes generating a file system snapshot wherein the snapshot is substantially empty. When metadata associated with a source file included in the snapshot is modified, the inode corresponding to the source file is copied to a shadow inode in the snapshot. When information is appended to a data block associated with a source file included in the snapshot, the inode corresponding to the source file is also copied to a shadow inode in the snapshot. When information in a data block associated with a source file included in the snapshot is overwritten or deleted, the inode corresponding to the source file is copied to a shadow inode in the snapshot and the original data block corresponding to the source file is copied to the snapshot.

摘要： Space is allocated on data storage devices in proportion to weights associated with the storage devices. The weights can be dynamically adjusted at any time in order to accommodate changes in the system and to better utilize the storage devices. The technique used to perform the allocating is independent of the weights used by the allocating. Further, the allocation technique can accommodate general purpose data streams having varying lengths and/or varying access patterns, as well as special purpose data streams, such as video streams.

摘要： A system, method and computer readable medium for deferring copy-on-write of a snapshot is disclosed. The method includes the generation of snapshot of a source file. Upon modification of a first data block referenced by the source file, the first data block is referenced by the snapshot and a second data block is allocated for the source file. Then, a first variable associated with the source file is set to a value indicating an incomplete source file data block and a second variable associated with the source file is set to a value indicating the valid portion of the second data block. Any portion of the second data block that is overwritten is considered valid. The second data block is then modified and the second variable is changed to reflect the modification. Upon reception of a read request, the corresponding portion of the second data block is retrieved.
