摘要： Accordingly a method and interface allows an attribute data base used by an Information Manager to be quickly populated and accurately maintained. A single Bulk Attribute Retrieval Request triggers the primary storage device to collect object attribute information. The method allows for selective collection of objects and attributes by providing filters and attribute lists in the Requests. The Request may be used to provide an incremental scan with appropriate time stamp filtering. In addition, the size of the results can be controlled by the IM by eliminating attributes that are not of interest to the IM. The Request is advantageously issued over a FileMover interface, which is an HTTP connection, and encoded in XML, allowing the IM to easily customize the Request as desired.

摘要： A protected file is retained in secondary storage for a retention period, and a corresponding stub file is retained in primary storage for the retention period. The stub file retains attributes of the file indicating a location of the file data in the secondary storage and indicting that the stub file is to be retained for the retention period. A system administrator may instruct a primary file server that a secondary file server supports retention based protection and it is desired to protect stub files corresponding to protected files that are migrated to the secondary file server. The primary file server may request the secondary file server to return a protection status of the file after migration. This enables automatic policy-based migration to both file level retention (FLR) and non-FLR retention protected secondary storage from diverse applications accessing FLR or non-FLR files in the primary storage.
摘要翻译：受保护的文件保留在辅助存储器中保留期限，并且相应的存根文件将保留在主存储中以保留期限。存根文件保留文件的属性，该属性指示辅助存储器中的文件数据的位置，并指示在保留期间保留存根文件。系统管理员可以指示主文件服务器辅助文件服务器支持基于保留的保护，并且希望保护对应于被迁移到辅助文件服务器的受保护文件的存根文件。主文件服务器可能会请求辅助文件服务器在迁移后返回文件的保护状态。这样可以实现基于策略的自动迁移，可以从访问主存储中的FLR或非FLR文件的各种应用程序的文件级别保留（FLR）和非FLR保留保护的辅助存储进行迁移。

摘要： Apparatus for detecting a single-frequency signal having a predetermined frequency in an analog signal includes means for converting the analog signal to a differentially encoded digital signal and detection means for detecting a single-frequency signal having the predetermined frequency from the differentially encoded digital signal. In a preferred embodiment, the detection means includes: means for detecting one cycle of the analog signal by detecting a signal maximum followed by detecting a signal minimum which is followed, in turn, by detecting another signal maximum; means for determining the length of the cycle, for determining whether the length is within predetermined bounds, and for keeping a count of such occurrences; and means for determining whether the count has reached a predetermined amount, whereby a single-frequency signal having the predetermined frequency has been detected.

摘要： This invention is a system and a method for operating a storage server in a data network using a new architecture. The system of operating a storage server includes a secondary storage that archives or stores a data object in transformed form such that the clients of the storage server can no longer access the data directly. The method of accessing the data object that is archived or transformed in a different form to the secondary storage includes recalling only those data blocks that are required for read or write operation.
