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： Systems, methods, and computer products for communicating between a client and server by identifying and separating file data streams within a file are provided. The method comprises indicating the type of file data stream to be transmitted and transmitting the indicated file data stream. The transmitted file data stream is compared with a stored data stream. A non-redundant file data stream is stored based upon the outcome of the comparison. The transmitted file data stream and stored data stream may be compared according to a deduplication table based on data stream profiles.

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： Method and system aspects for supporting hierarchical file system management functions across multiple operating system platforms in a data processing system are provided. In these aspects, a code base provides predetermined functionality for each of a plurality of operating system platforms of the data processing system. Further, a common kernel extension is utilized by the code base, with the common kernel extension supporting a hierarchical file system of the data processing system. The common kernel extension supports file system intervention in the hierarchical file system by handling an interface between each operating system platform and a file system. Also, the common kernel extension further handles an interface between each operating system platform and a device driver.

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 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.
