摘要： A method for handling snapshots together with migrated files in a hierarchical storage management may be provided. The method comprises managing files using a first-tier storage and a second-tier storage. The files are organized in a managed file system—e.g., a hierarchically managed file system—in the first-tier storage. The method comprises further creating a snapshot of a portion of the files of the first-tier storage, thereby creating a hidden directory in the file system, deleting a migrated file, and moving the stub file relating to the file to be deleted in the first-tier storage to the hidden directory.

摘要： Operating a data processing and storage apparatus to perform continuous backup monitoring for a collection of stored file system objects. In response to changes respective to a number of the file system objects, a set of Data Management Application Program Interface (DMAPI) events is created. For each of the events, accessory file system object information relative to a file system object subject to the change is determined. The events are grouped into an event group and a unique group identifier and an overall group size count are assigned to each of the events included in the event group. The events are sent together with the respective accessory file system object information, the respective group identifier and the respective group size to a number of backup clients registered as applications. The backup clients are to process the events together with the respective accessory file system object information, the respective group identifier and the respective group size into a number of backup requests.

摘要： In an approach to backup and restore one or more clone file trees, one or more processors generate a clone management table. One or more processors record a clone management information in the clone management table about each clone file. To backup a clone file, one or more processors update the clone management information, and store one or more data blocks that are in the clone file trees. To restore a clone file, one or more processors analyze a clone management information and restore one or more data blocks in the clone file. To restore a clone file parent, one or more processors analyze a clone management information and restore one or more data blocks in the clone file parent. To restore a clone file tree, one or more processors analyze a clone management information and restore one or more data blocks in the clone file tree.

摘要： The present disclosure provides a hierarchical storage management system for storing data. A first controller receives a request to migrate a data item to a first storage tier. The data item is associated with at least an initial object ID. The first controller, in response to the request, generates a new object ID and identifies a first record in a data structure, wherein the initial object ID is identical to an object ID of the first record and to a parent object ID of the first record. The first controller replaces the object ID of the first record with the new object ID, creates in the data structure a new record that is associated with the data item, sets an object ID of the new record and a parent object ID of the new record to the initial object ID, and stores the data item to the first storage tier.

摘要： Automatically configuring backup client systems and backup server systems in a backup environment includes the following steps: determining if a new backup client system is available in the backup environment; in case of an available new backup client system a backup configuration module performs the sub-steps of: determining data types the new backup client system has to backup; determining corresponding backup policies for the determined data types based on a backup policy table mapping data types with backup policies; selecting a backup server system for the determined data types based on a backup server table including connection details of available backup server systems; configuring the determined backup policies for the data types of the new backup client system on the selected backup server systems; and updating the backup server table with an identifier of the new backup client system and an identifier of the backup policy.
