摘要： Disclosed is a system to diagnose and handle errors in an automated hierarchical storage management system. A host system requests an access operation on a first file, such as a logical volume, in a first storage device, such as a magnetic hard disk drive. A server processes the host request to determine whether the first file is resident in the first storage device. The server initiates a recall of a second file, such as a physical volume, in a second storage device, such as tape cartridges, optical disks, etc., corresponding to the first file upon determining that the first file is not resident in the first storage device. The second file is then copied from the second storage device to the first file in the first storage device upon determining that the second file is accessible. The server further determines whether the recall of the second file has failed. Upon determining that the recall has failed, the server checks a table in a memory within the server to determine whether there is error information listed for the second file involved in the failed recall. The server then takes appropriate action based on the error information in the table.

摘要： Replacing a human operator, an automated message processing system communicates with a data storage subsystem that includes a tape library and a storage controller. The automated message processing system receives messages from a data storage subsystem concerning the availability of tape drives in the tape library. Such messages are selectively routed to one of many specialized expert local facilities (ELFs) for performance of a designated function, such as generation of an appropriate output messages. The ELFs receive input messages and transmit output to the data storage subsystem in order to oversee allocation and use of data storage drives in the data storage subsystem.

摘要： Provided are a system and article of manufacture for merging metadata on files in a backup storage. A query is received for information on files from a file system for a client node. A determination is made of metadata for files in a backup storage for the client node stored external to backup sets. At least one backup set in the backup storage for the client node is processed to determine metadata for files included in at least one backup set. The determined metadata for files in the backup storage and for files included in at least one backup set is merged to form merged metadata. The query is executed against the merged metadata to determine files whose metadata satisfies the query. Results including information from the merged metadata on the determined files are returned.

摘要： Provided are techniques for data deduplication. A chunk of data and a mapping of boundaries between file data and meta data in the chunk of data are received. The mapping is used to split the chunk of data into a file data stream and a meta data stream and to store file data from the file data stream in a first file and to store meta data from the meta data stream in a second file, wherein the first file and the second file are separate files. The file data in the first file is deduplicated.

摘要： Provided are a method, system, and program for transferring data between system and storage in a shared buffer. An application requests a buffer from a component. The component allocates a buffer and returns to the application a first offset in the buffer for application data and a second offset in the buffer for a first header. The application writes the application data at the first offset in the buffer; and writes the first header at the second offset in the buffer. A second header is written to a third offset in the buffer.

摘要： Systems, methods, and computer products for separating file data streams for improved progressive incremental processing are provided. The method comprises identifying data in a file, prior to transmission of the data in a data stream to a second system, such that the second system can distinguish first data from second data in the file. The method further comprises processing the first and second data to determine whether the first or second data has changed, and transmitting the first data to the second system in response to determining the first data has changed, so that the first data is stored in a data storage medium in association with third and fourth data previously stored without replacing the third data and fourth data, wherein the third and fourth data comprise older versions of the first and second data, respectively.

摘要： Provided are techniques for accessing information. A partial key index is created, wherein the partial key index includes one or more partial key index (PKI) entries, wherein each PKI entry identifies a portion of a metadata object, wherein the metadata object includes metadata entries, each of which corresponds to an associated data object. The partial key index is used to locate one or more PKI entries, wherein each of the one or more PKI entries corresponds to one or more data objects in one of the one or more composite objects. Each of the one or more PKI entries is used to retrieve location information of metadata in a metadata object for each of the one or more composite objects. The metadata from each metadata object is loaded into a database using the location information.

摘要： Disclosed is a system for backing up files in a distributed computing system. A file server maintains files in a shared name space. The file server provides a first backup client program and a second backup client program with access to the files in the shared name space. The first backup client program initiates a backup request to backup a requested file. A determination is made as to whether the requested file is maintained in a shared name space. The backup request is transmitted to the second backup client program upon determining that the requested file is maintained in the shared name space. The second backup client program transmits a message to the file server to provide the requested file. The file server transmits the requested file with the file server to the second backup client program. The second backup client program then transmits the requested file to a backup server program. The backup server program stores the requested file in a storage device.
