    摘要: Aspects of the invention relate to creating a snapshot of a file system on an OAS system. A snapshot of a file system is an image of a file system at a particular point in time. A snapshot of a file system may be used to restore the file system to its state at the time of creation of the snapshot in, for example, situations where the file system has become corrupted.

    摘要: One embodiment is a method and apparatus for modifying retention periods in a storage system, in which previously defined retention periods for units of data may be reduced. In another embodiment, the retention period of a unit of data may be modified in response to the occurrence of an event by renewing previously defined retention periods until the occurrence of the event is detected. If the occurrence of the event is detected, a retention period associated with that event may be established for the unit of data. In yet another embodiment, retention classes are used to define retention periods for units of data so that the retention period of a unit of data may be modified without modifying the unit of data itself. In a further embodiment, a request to the storage system to reduce a retention period includes authentication information that the storage system may use to verify the request.

    摘要: In one embodiment of the invention, a utility may be installed (e.g., by a system administrator) on a storage system. The utility may read content units on the storage system that are stored in one data format, and convert the content units to a second data format. In one embodiment, in response to a read request for a content unit, a data format in which to return the content unit may be selected and the content unit may be returned in that data format. In another embodiment, mapping information may be created that specifies in which data format a content unit should be returned in response to a request for the content unit. The mapping information may be stored either on the storage system that stores the content unit, the computer requesting access to the content unit, or any other computer or device in the computer system.

    摘要: One embodiment of the invention is directed to providing a single instance storage capability in a content addressable computer system that stores content units in a time-based directory structure. Another embodiment is directed to managing access to content units that do not include a timestamp in their content addresses, in a time-based directory structure. A further embodiment is directed to accessing replicated content units stored on a computer, based on a time of replication. A further embodiment is directed to employing a bitmap in a time-based directory structure which may be used to indicate whether any content units stored during a specified time range are stored in the directory structure.
