System Data Backup Patents (Class 707/650)
  • Patent number: 8452730
    Abstract: A method of archiving a set of source tables in a database system. Each source table has a plurality of rows. Initially, a consistency point for the set of source tables is established. The database system creates a log record for each change (insert, modify, or delete) effected to a row of the source tables subsequent to the consistency point. Substantially all source table rows are copied to an archive (a data storage object that is external to the database system). Then the accumulated log records for the affected source tables are distilled and appended to the archive.

  • Patent number: 8386731
    Abstract: Techniques for migrating persistent data of virtual machines between and across data stores are optimized using special tracking data structures and monitoring methods. Special tracking data structures include an incremental change block tracking bitmap that indicate what blocks have been modified during a copy operation. The determination of whether any one block has been modified during the copy operation is based on whether or not the copy operation has progressed past that block. Another special tracking data structure is a Bloom filter, which provides a space-efficient data structure for keeping track of dirtied blocks. In addition, heat-based optimization techniques are applied so that blocks that are frequently updated are filtered and not transferred to the destination data store until the last iteration of the migration process.

  • Patent number: 8306951
    Abstract: A cluster manager is configured to manage a plurality of copies of a mid-tier database as a mid-tier database cluster. The cluster manager may concurrently manage a backend database system. The cluster manager is configured to monitor for and react to failures of mid-tier database nodes. The cluster manager may react to a mid-tier database failure by, for example, assigning a new active node, creating a new standby node, creating new copies of the mid-tier databases, implementing new replication or backup schemes, reassigning the node's virtual address to another node, or relocating applications that were directly linked to the mid-tier database to another host. Each node or an associated agent may configure the cluster manager to behave in this fashion during initialization, based on common cluster configuration information. Each copy of the mid-tier database may be, for example, a memory resident database. Thus, a node must reload the entire database into memory to recover a copy of the database.

  • Patent number: 8281094
    Abstract: When performing asynchronous remote copying, whether or not a disaster has occurred at a main site is judged at a remote site; and if the disaster has occurred, recovery processing is immediately started at the remote site. When asynchronous remote copying is performed between a controller and a controller, the controller transfers remote copy target data in a storage apparatus and command information via a remote copy channel to the controller; and after receiving the remote copy target data, the controller stores the remote copy target data in a storage apparatus; and if the controller fails to receive the command information within a set time period, the controller judges that a disaster has occurred, and then outputs the judgment result to a backup center server; and the backup center server executes recovery processing based on data in the storage apparatus when the disaster has occurred.

  • Patent number: 8165994
    Abstract: A server auditing process that stores only a single up-to-date data record along with the differences relative to previous changes in the record that allow the user to move “backward in time” to recreate previous values. The auditing feature introduces a baseline database table and a difference database table for each existing database table. The baseline table stores the most recent auditing data and the differences table complements the baseline table by storing pairs in the form of attribute name and previous value. By applying difference rows to baseline data, the user is able to recreate the data as it existed at any given timestamp and at a minimal storage cost. The architecture minimizes the impact of auditing on system performance by employing an asynchronous priority queue so that task processing is deferred until the system has adequate resources and other work is not affected.

    Abstract: Techniques for performing window-by-window remastering are described, in which the mechanism used by nodes to determine the resource-to-window mapping is separated from the mechanism used by the nodes to access resource information. For example, all nodes of a multiple-node system may use the same hash function to determine which resources are involved in a remastering window. However, the resource indexes employed by the nodes to access resource information need not use that same hash function. For example, in nodes where the resource indexes are hash indexes, different nodes may use different hash functions. Further, some or all of the nodes may use mechanisms other than hash indexes to access the resource information.

  • Patent number: 7814057
    Abstract: 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.

  • Publication number: 20100217751
    Abstract: The present invention comprises a method and system for safely deleting files and registry keys from the operating system. The process works by having a file system filter or registry monitor intercept commands to delete information. Instead of deleting the file or registry key, the system monitor places the information in a list of blocked files, making the file and key inaccessible to all other programs. If the machine later experiences errors, access to the file can be restored. If the machine is unaffected by the apparent deletion of the file, then the file is permanently deleted.

  • Patent number: 7769716
    Abstract: A data warehouse characterized by a plurality of fact tables and at least one dimension table is backed up. For fact tables that are static, those fact tables are backed up using a first backup method that is, for example, optimized for static data. For example, the first backup method may be at the file system level, below the database level, and can be a very time and computationally efficient way to synchronize blocks of data. Thus, for example, the first method may be a method that is not “database-aware” and does not consider the database structure in its backup processing. For fact tables that are dynamic, those fact tables are backed up using a second backup method. For example, the second backup method may account for the dynamic nature of data in the portion being backed up by being, for example, “database aware.” In addition, the at least one dimension table is backed up.

  • Patent number: 7743032
    Abstract: A programmable video recorder (PVR) includes a writer application programming interface (API) and a reader API that operate essentially independently to enable the PVR to be networked to multiple reader applications. The writer API creates a backing store and a shared memory mapped file. The backing store stores streamed data in temporary files. The shared memory mapped file stores state information of the backing store files. The reader API receives requests from reader applications to access the stored streamed data. In response to the requests, the reader API permits the reader applications to access the shared memory mapped file to determine where the stored streamed data is located. Upon locating the stored data, the reader API permits the requesting reader applications to access the stored streamed data.
