摘要:
The present invention enables a unified way of accessing files generated by application programs configured to store contents in files in different formats, without using a conversion program.A database for holding correspondence between an identifier of a content and a storage position of the content is generated based on a backup catalog generated by a backup server, and contents are accessed by using this database. Contents generated by a plurality of different application programs are accessed in a unified way using a single name space.

When plural processing programs for generating post-processing data which is a source of services to be provided are present, a relationship between post-processing data and a data group which is a source of the post-processing data is managed. The processing units acquire pre-processing data, execute given processing, and generate post-processing data as a result of the processing. At an opportunity to acquire the pre-processing data, a process ID indicative of ordering of the acquisition, and not updated before and after the given processing is allocated to acquired pre-processing data. The generated post-processing data is stored, and in extracting the post-processing data satisfying the given data search condition, the post-processing data having a process ID equal to or before the process ID that is latest in the post-processing data and oldest among the respective processing units is extracted from the post-processing data that satisfies the data search condition.

A progress status management system comprises a management target system configured to execute a series of processes to the file, which includes a plurality of process units configured to execute a process to a file, and a progress status management unit configured to manage a progress status of a process executed by the process unit included at the management target system. The progress status management unit, in a case of acquiring the first identification information of a file in a first process unit, acquires the first identification information of the file in the second process unit, and links the acquired first identification information in the first process unit and the acquired first identification information in the second process unit to the same second identification information.

摘要:
A computer system, comprising: a file server; a metadata server; and a business server, the metadata server being coupled to a storage apparatus for providing a save area for storing at least one file that is removed from the file server, the metadata server storing a metadata repository for managing metadata of a file and the files stored in the save area, the metadata server being configured to: store a file as a saved file in the save area, in a case of detecting that the file stored in the file server is to be removed; and store information indicating a location of the file in the file server and information indicating the location of the saved file in the save area in association with each other in the metadata repository.
摘要:
There is provided a storage subsystem having a virtual volume and a page volume which has a page physical area allocated to the virtual volume. The storage subsystem divides an address space of the virtual volume into a plurality of pages, classifies each of the pages into one of a plurality of states including at least a first state and a second state, and further divide a page which is classified into the second state into a plurality of segments to managed the page classified into the second state. The first state is a state in which a page physical area is allocated to the page from the page volume, and the write data is stored in the page physical area. The second state is a state in which the predetermined pattern data and the segment are managed, in the memory, by correlating with each other.
摘要:
A home storage (a first storage device) installed in each home is provided with an area for a user to store data (user area) and an area for storing ads (ad area). The first storage device checks interest and favorite information for the user in the user area, and transmits the interest and favorite information at the same time backup is performed in a second storage device at a remote site. The second storage device selects a suitable ad based on the interest and favorite information from the first storage device and transmits the selected ad to the first storage device. The user views the transmitted ad when viewing content in the first storage device. The user's viewing record for the ads is kept as statistical data, and the second storage device compiles the record, charges a sponsor an ad charge, thereby subsidizing the usage charge for the first storage device regardless of online or offline connection.
摘要:
Upon receiving a primary/secondary switching command from a secondary host system, a secondary storage control device interrogates a primary storage control device as to whether or not yet to be transferred data that has not been remote copied from the primary storage control device to the secondary storage control device is present. In the event that yet to be transferred data is present, the secondary storage control device receives yet to be transferred data from the primary storage control device and updates a secondary volume. The primary storage control device then manages positions of updates to the primary volume due to host accesses to the primary volume occurring at the time of the secondary storage control device receiving the primary/secondary switching command onwards using a differential bitmap table.
摘要:
The risk of a third party referring to or using backup data without authorization upon restoring such backup data in an HDD recorder is mitigated. First authentication information of a user as the HDD owner and second authentication information of an engineer of a repair plant are registered in an online backup service system. The first authentication information is used when backing up data recorded in the HDD to the online backup service system, and the second authentication information is used when restoring the data backed up to the online backup service system. The data backup processing and data restoration processing are executed only when the authentication information is appropriate. Since the user will directly receive an email from the online backup service system regarding who restored which data at what time, such user will be able to audit the data restoration process independently from the person recovering the data.
