摘要： Methods for utilizing a locality table when performing data deduplication are disclosed. One method involves accessing a locality table stored in memory. The locality table includes several signatures, each of which identifies one of a several data units that were consecutively added to a deduplicated data store on a persistent storage device. The method then involves searching the locality table for a new signature of a new data unit, in order to determine whether a copy of the new data unit is already present in the deduplicated data store. If the new signature is not found in the locality table, a pointer table is accessed. The pointer table indicates a subset of a set of signatures stored on the persistent storage device. In response to accessing the pointer table, the subset of the set of signatures, indicated by the pointer table, is searched for the new signature.

摘要： A method of creating backup files having less redundancy. The method creates a backup file by creating an overhead segment for each file that is to be backed up and creating a data segment containing the data that is to be backed up for each file. After creating the overhead segment and the data segment, the overhead segment is placed into an overhead stream data segment is stored in memory. The overhead segment is also positioned in the overhead stream with a pointer that identifies the data segment within the memory. For backups of subsequent servers or the same server at a later time, the backup software will create a separate overhead stream. However, a plurality of overhead streams may contain pointers to the same data segments such that redundant data segments do not need to be stored in a backup server.

摘要： A method, system, and computer readable medium for asynchronously processing write operation on a volume having copy-on-write snapshots. In one embodiment, the method comprises the steps of: updating a normal mirror with write data associated with a write operation for the volume; asynchronously copying the write data from an asynchronous mirror to at least one copy-on-write snapshot; and, once the at least one copy-on-write snapshot is updated, updating the asynchronous mirror with the write data from the normal mirror.

摘要： A plurality of routing entries may be stored in a routing table. Each routing entry may include information usable for routing a message through a network. As new routing entries are received or created, each new routing entry may be added to the routing table. However, if there is not sufficient memory or storage to add the new routing entry to the routing table, then the least recently used existing routing entry in the routing table may be replaced with the new routing entry. In the event that the replaced routing entry is needed later, the replaced routing entry may be re-created.

摘要： A method and system for efficient space management for single-instance-storage volumes is provided. A backup module storing data within a collection of containers according to access locality and retention time of the data, wherein the retention time defines an amount of time the data is stored within the collection of containers before deletion of the data, and the access locality comprises an order in which the data is to be accessed is further provided. A compaction module compacting the stored data by selecting at least two containers among the collection of containers, wherein the selection is performed using a predetermined criteria that includes access locality and retention time of the data is also provided. The compaction module distributes the data among the at least two containers. The compaction criteria creates an imbalance among the containers to create more empty, full, or nearly full containers.

摘要： A system and method for visually depicting component states in a computing system. A graphical analysis tool includes a graphical user interface for use in viewing the history of a selected component. A user selects a system component for viewing and then using a timeline “drags” the state of the selected component to various points on the timeline in order to view states of the component at the selected point in time. States of the selected component may also be played forward or backward in a continuous manner. Logging agents in the system are configured to log data corresponding to detected events and forward the log data to a central repository. The analysis tool may access the data in the repository for use in creating visual displays. Point-in-time snapshots of a component may also be stored in the central repository and used to reproduce the history.

摘要： System and method for tracking statistics at the subfile level and transparently placing or migrating inactive or less active blocks of data to other storage devices. Embodiments may provide mechanisms to track statistics at the subfile level of files including, but not limited to, database files, and to transparently place or migrate inactive or less active blocks of data of the files from higher-performing, typically more expensive, storage to lower-performing, typically less expensive, storage, while placing or migrating active blocks of data of the files to higher-performing storage, based on the subfile-level statistics rather than on file-level timestamps. In some embodiments, knowledge of file structure (e.g., database file structure), for example knowledge of database partitions with header blocks and data blocks in databases using data partitioning, may be used to separate more active and less active blocks of data of files onto storage with different performance and/or other characteristics.
