    摘要: A system and method for serialization and/or de-serialization of file system item(s) and associated entity(ies)is provided. A file system “item” comprises a core class which can include property(ies). An item can be simple or compound (e.g., includes other item(s) embedded in it). Associated with an item can be entity(ies) such as fragment(s), link(s) with other item(s) and/or extension(s). Through serialization, a consistent copy of the item and associated entity(ies), if any, can be captured (e.g., for transporting of the item and to reconstruct the item on a destination system). The serialization system includes an identification component that. identities entity(ies) associated with an item and a serialization component that serializes the item and associated entity(ies). The serialization component can further serialize a header that includes information associated with the item and associated entity(ies). The header can facilitate random access to the item and associated entity(ies) (e.g., allowing a reader to interpret/parse only the parts in which it is interested). The serialization system can expose application program interface(s) (API's) that facilitate the copying, moving and/or transfer of an item and its associated entity(ies) from one location to another location.

    摘要: The subject invention relates to systems and methods that enable pausing and/or resuming a backup of file system items. The items are backed up in an order based on a unique property associated with each of the items. When the backup is paused, the unique property associated with a last backed up item prior to the pause is stored. Additionally, a timestamp associated with a snapshot from which the backup was taken can be stored with the unique property. Upon being resumed, the backup can continue from the paused location via utilizing the stored unique property. The backup can be resumed either employing an original snapshot associated with a time prior to the pause or a second snapshot related to a subsequent time. The subject invention can perform an initial backup of file system items and/or an incremental backup of such items. Additionally, the subject invention can support backing up a file system at disparate levels of granularity such as, for example, an item level.

    摘要: Systems and methods are disclosed that facilitate providing page-level database restore functionality upon detection of a corruption event. Updates to a data page in a database can trigger generation of a snapshot of the data page, and an update log can be maintained that stores information related to page updates. Subsequent snapshots can be generated at predetermined intervals and can trigger truncation of a log segment and initiation of a new log segment. Upon detection of page corruption, a most-recent uncorrupt snapshot of the corrupt page can be identified, copied to the location of the corrupt page in the database, and modified according to the log segment associated with the uncorrupt snapshot to make the page current as of the corrupting event, all of which can be performed to restore the database without having to take the database offline.

    摘要: The present invention relates generally to database and file system management and, more particularly, to automatic database and file system maintenance and repair to ensure data reliability. Various aspects of the present invention relate to responding and correcting data corruptions at a data page level for all data page types, as well as to recovery (including rebuild or restore operations) for various scenarios including, without limitation, index page corruptions (clustered and non-clustered), data page corruptions, and page corruptions in the log file.

    摘要: The present invention is directed a logical consistency checker (LCC) working alone or in conjunction with a physical consistency checker (PCC) and/or a data reliability system (DRS) for a database files system of a hardware/software interface system. Logical data correction pertains to logical data corruptions for entities (e.g., items, extensions, and/or relationships in an item-based operating system, where an item-based operating system is one example of an item-based hardware/software interface system). In this regard, a LCC analyses and corrects logical damage to entities representatively stored in the data store in order to ensure that all such entities in said data store are both consistent and conform to the data model rules.

    摘要: Systems and methods are disclosed herein that facilitate automatic database backup and restore for databases resident in personal computing devices, and which are transparent to a user, utilizing database page mirroring. Modifications to a data page in a data file can be validated and written to a backup, or mirror, database and then subsequently written to an original database after a predetermined time. An I/O latch on a mirrored data page can be limited to a duration of a single I/O write operation to facilitate sequential data page writing to each of the databases while mitigating potential for both databases to be written simultaneously, which can detrimentally affect data quality during a recovery operation.
