摘要： Techniques for managing data stored in a hierarchical storage management (HSM) system are provided. A first controller receives a request to migrate a data item to a first storage tier managed by the first controller, wherein the data item is not associated with an object ID and a HSM status value indicates that the data item is resident on a second storage tier. The first controller generates an initial object ID, creates a new record for the data item in a data structure, sets an object ID field and a parent ID field of the record to the initial object ID. The first controller stores the data item on the first storage tier and sends an acknowledgement identifying the initial object ID as an object ID of the data item to a second controller that manages the second storage tier. The second controller updates the HSM status value.

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.

摘要： A computer receives a set of objects from a client, whereby at least one of the objects of the set are respectively associated and encrypted with a unique file encryption key (FEK). The computer encrypts each of the FEKs with a common master encryption key, MEK, resulting in respective locked keys. In an initial backup, the encrypted objects together with their associated locked keys are transmitted to a backup server where a first module determines if locked key has changed via referencing an encryption state associated with the encrypted objects. If an MEK has changed, the existing FEKs are re-encrypted with the changed MEK to generate new locked keys, and, in a subsequent backup operation, sending the new locked keys to the backup server to replace the existing locked keys, while avoiding transmitting to the backup server the objects whose associated FEKs are affected by the changed MEK.

摘要： The present invention relates to a method for data access in a storage infrastructure. The storage infrastructure comprises a host system connected to at least a first storage system and a second storage system. The first storage system receives, from the host system, a write request for storing a data chunk, the write request is indicative of a first identifier of the data chunk. The first storage system calculates a hash value of the received data chunk using a hash function. The first storage system determines a first storage location in the first storage system of the data chunk and sends a write message including the hash value, the first identifier and the first storage location to the de-duplication module. The de-duplication module determines whether the hash value exists in the data structure.

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.
