The identified series name, bucket descriptions and organization thereof may be stored in a repository and presented to users.

Abstract: A transaction safe file system uses two sets of file allocation tables and bitmap images to perform file modifications on one of the sets while the other set remains a last known good set. After a modification is complete, a pointer is changed to the newly modified set, and the newly modified set becomes the last known good set. The sets are then synchronized. The file allocation table is used to define cluster chains while the bitmap image is used to determine if a cluster is free or not. In some operations, only the bitmap image may need to be manipulated. The file system may be used in a transaction safe mode as well as a non-transaction safe mode.

Abstract: A storage system according to certain embodiments includes a repository of client-side data block signature information representative of a set of data blocks stored in a primary storage subsystem. In some cases, the system sources data blocks for secondary copy and restore operations from the primary storage subsystem instead of the secondary storage subsystem. Where multiple primary storage components (e.g., multiple client computing devices) contain copies of a data blocks involved in a secondary copy or restore operation, the system can decide which client to source the data block from based on sourcing criteria.

Abstract: Techniques for supporting a portable index include, in response to determining that a removable computer-readable storage medium is recently mounted on a particular drive having a particular drive identifier, determining a particular media identifier for the removable computer readable storage medium. Before harvesting metadata from each file of a set of one or more files on the removable computer-readable storage medium, it is determined whether a portable index file is stored on the removable computer-readable storage medium. The portable index file includes, for each file of the set, data that associates the media identifier (312) and a relative directory path (314) for one file of the set with metadata (316) for the one file. If the portable index file is stored, then an index is caused to be retrieved from the portable index file without harvesting metadata from each file of the set.

Abstract: A storage system according to certain embodiments includes a client-side signature repository that includes information representative of a set of data blocks stored in primary storage.

Abstract: A system that implements a distributed lock service may include a failure detector for servers and sessions, and may track the state of sessions on a per-client-connection basis. It may include an external lock information database that stores lock state information and that supports a higher write throughput rate than a distributed state manager. Each database record may store an identifier of a session during which a lock on a respective item was obtained (if any) and a staleness indicator. A distributed state manager may maintain a session identifier and a respective staleness indicator for each established session, and may push updates to this session information to interested client processes, which may cache the information. A client process wishing to lock an item may determine whether it can do so dependent on the information in a corresponding database record and on its own cached session information.

Abstract: A technique for transaction recovery by one transaction manager of another transaction manager's transactions in which each transaction manager is adapted to manage two phase commit transactional operations on transactional resources and to record commit or rollback decisions in a transaction recovery log. The recovery transaction manager detects apparent unavailability of the another transaction manager for transaction processing and initiates a transaction recovery process for the another transaction manager's transactions. This process also determines whether any of the transactions of the another transaction manager have all respective resources prepared to commit without there yet being a pending commit decision record in the another transaction manager's recovery log. If so, the recovery transaction manager writes a rollback record indicating an intention to roll back the identified transaction, in the another transaction manager's recovery log provided no commit decision record has been recorded.
