摘要： A mechanism is provided for adaptively assigning of a plurality of data management application instances to a plurality of data objects. The mechanism determines a processing load for a plurality of data management application instances for performing a data management task based on history data being descriptive of the data objects which have been affected by previous data management tasks, each of the data management application instances being assigned to at least one sub-section of a tree being descriptive of a storage structure of the data objects by means of a set of separation points for each one of the data management application instances. The mechanism adapts the separation points in the tree for balancing the expected processing loads of the data management application instances for a future data management processing task.

摘要： A method of managing remote storage sets retention grace period, an archive retention period, and a backup retention period all equal to the same time period. In response to receiving a request to migrate a file to remote storage by any one of HSM, archive, or backup, the method creates a stub of the file, stores the stub in local storage, moves the file to remote storage, and backs up the file at the remote storage. In response to receiving a request to access an HSM file, the method determines if the requested file is in HSM remote storage; if so, the method returns the requested file from remote storage; if not; the method determines if the requested file is in archive remote storage or backup storage and, if so, returns the requested file from said remote storage. In response to receiving a request to access an archived file, the method determines if the requested file is in archive remote storage; if so, the method returns the requested file; if not, the method determines if the requested file is in HSM remote storage or backup remote storage and, if so, returns the requested. In response to receiving a request to access a backup file, the method determines if the requested file is in backup remote storage; if so, the method returns the requested file; if not, the method determining if the requested file is in archive remote storage or HSM remote storage and, if so, returns the requested file.

摘要： A method for managing a mass storage system wherein the mass storage system comprises a first storage space and a second storage space. A file index is generated which lists in a uniformly distributed way each file along with a first characteristic quantity, a second characteristic quantity, and a status information, wherein the status information specifies if the file is held on the first storage space or on the second storage space. A sample of files is selected from the file index. The sample of files contains a given number of files, wherein the status information of each file of the given number of files specifies the file to be held on the first storage space. The first critical value is determined by use of the first characteristic quantity of each file comprised in the sample of files and a second critical value is determined by use of the second characteristic quantity of each file of the sample of files. Then, a first subset of files comprising each file for which the first characteristic quantity is larger than the first critical value and for which the second characteristic quantity is larger than the second critical value and which is specified by the status information to be held on the first storage device is determined.

摘要： The invention relates to a method and data processing system of managing a storage system, wherein the storage system comprises a first storage space and a second storage space, wherein the first storage space comprises a plurality of files, wherein for each file of said plurality of files at least one attribute is specified, and wherein a policy is assigned to each attribute. The method comprises the steps of determining a policy-specific probability distribution for each policy and of determining a policy-specific probability for each file by use of the policy-specific probability distribution. The method further comprises the step of determining a total probability for each file by use of each policy-specific probability and of moving each file of the plurality of files having a total probability equal to 1 from the first storage space to the second storage space. The method further comprises the step of moving files of the plurality of files having a total probability between 0 to 1 if the storage space used on the first storage space reaches a high threshold value until a low threshold value is reached, wherein the low threshold value and the high threshold value are predetermined.
