  • Patent number: 10769595
    Abstract: Implementations of the disclosure provide a system for verifying publisher suggestions. The system includes a memory to store profile data for one or more entities; and a processing device coupled to the memory to identify an indication from a source of a suggested change to an online listing data associated with an entity at one or more provider systems. It is determined whether the suggested change matches previously stored information regarding the entity. Responsive to detecting a difference between the suggested change and the stored information, a communication with a client device associated with the entity is initiated based on the suggested change. Input data is received from the client device based on the initiated communication that indicates whether to accept or reject the suggested change. Thereupon, the suggested change is applied to the online listing data at the one or more provider systems in accordance with the input data.

    Abstract: Various systems and methods for cooperative tiering between an application and a storage device. One method can include receiving information from the application where the information identifies a storage object and identifies a location in a storage device. The location identifies one or more tiers of a plurality of tiers included in the storage device, and the storage object is assigned to the one or more tiers. The method also involves detecting whether the storage object is stored in the one or more tiers. If not, the storage device copies the storage object to the identified location. The information can also include an instruction by the application to move the storage object from a first tier to a second tier.

When a report is requested, a date and time when data in the report data cache was generated is compared with a date and time when data was collected by each of one or more data collectors that gather data used to generate the report data. If one of the data collectors has collected data since the data for the report in the report data cache has been updated, the data for the requested report will be regenerated from the data collected from each of the data collectors associated with the report and the regenerated data inserted into the report data cache. Subsequent requests for the report can be satisfied by generating the report using the data stored in the report data cache rather than regenerating the report data each time a request for a report is received.

  • Patent number: 8244841
    Abstract: A system and method for performing various operations on group policy objects, by manipulating group policy objects as a single entity to perform backup, restore, import and copy operations. The backup operation transfers the various subparts of a selected group policy object to a file system. A restore operation restores a backed-up group policy object to its domain, in the same state as when the backup was performed. An import operation transfers the settings within a backed-up source group policy object to a destination group policy object, erasing its previous settings. A copy operation transfers the settings from a source group policy object to a new group policy object. Copy and import operations can be cross-domain, and a migration table can be used to convert security group and UNC pathnames as appropriate for the destination domain. Backup management, rollback of incomplete operations, and support for application deployment are also provided.

  • Patent number: 8032494
    Abstract: The present invention provides a system and method for archiving data that reduces the time needed for archiving by performing one or more preliminary comparisons of administrative data to preset criteria. Exemplary administrative data may include a resubmission date of a data element that is determined by processing of a rule set and stored with the data element so that it can be used for archiving. The first step of the archiving process may be to compare the resubmission date to the current date. If the resubmission date is less than or equal to the current date, the archiving process continues. Otherwise, the archiving process does not proceed and the application database continues to maintain the data element. Because the resubmission date is stored with the data element to be archived, the data element need only be retrieved from the database to perform the initial check. Only data elements having a administrative data that meet the initial criteria are processed to determine if they should be archived.

  • Patent number: 8015146
    Abstract: In a networked information system, a portion of the information processing is offloaded from servers to a storage system to reduce network traffic and conserve server resources. The information system includes a storage system storing files or objects and having a function which automatically extracts portions of text from the files and transmits the extracted text to the servers. The text extraction is responsive to file requests from the servers. The extracted text and files are stored on the storage system, decreasing the need to send entire files across the network. Thus, by transmitting smaller extracted text data instead of entire files over the network, network performance can be increased through the reduction of traffic. Additionally, the processing strain on physical resources of the servers can be reduced by extracting the text at the storage system rather than at the servers.

    Abstract: Tombstones can be removed from a data store without data corruption. Tombstones placed into a forgotten knowledge list can be compared against each other and/or items in a tombstone table, and deleted when tombstones representing subsequently deleted items are extant. Also, creation database version information can be kept along with database items, and databases can record database version information when they synchronize. If a synchronizing database discovers an item that it does not have, but the creation database version information associated with the item reflects that the synchronizing database “should” have the item, then it can be inferred that the item was subsequently deleted, and item resurrection can be prevented.

    Abstract: Data on a primary data volume is restored by generating an image of the primary data volume at a specified point-time based on data stored on a backup data volume, where the data stored on the backup data volume includes data written to the primary data volume and stamps to indicate when the data was written to the primary data volume. The primary data volume is restored based on the generated image of the primary data volume. Additionally, while the primary data volume is being restored, read/write requests to the primary data volume are satisfied using the generated image of the primary data volume.

  • Patent number: 7720819
    Abstract: A method and apparatus for protecting file data is provided that combines or merges revision based backup with backup based on time intervals. One embodiment is directed to a method for protecting data contained in a file of a computer system, wherein the computer system is useable to create multiple successive file versions. The method comprises the steps of specifying a maximum number of file versions that can be stored collectively at first and second storage locations, and apportioning the maximum number into a first number of file versions and a second number of file versions. The method further comprises storing the most recent of the multiple file versions, up to a number equal to the first number, at the first storage location. A number of file versions respectively created before the stored most recent versions, up to a number equal to the second number, are stored at the second storage location, over a pre-specified time period and in accordance with a pre-specified strategy.
