A computer-implemented method for optimizing a global lifetime for a plurality of magnetic tape cartridges for a magnetic tape library is disclosed. The computer-implemented method includes storing a magnetic tape cartridge lifecycle table for a set of parameter values. The set of parameter values include: volume serial numbers of the plurality magnetic tape cartridges, lifetime metric values of the plurality of magnetic tape cartridges, and end-of-life-indicator values for the plurality of magnetic tape cartridges. The computer-implemented method further includes selecting a magnetic tape cartridge from the plurality of magnetic tape cartridges based on the set of parameter values and a selection criteria, wherein the selection of the magnetic tape cartridge optimizes the global lifetime of the plurality of magnetic tape cartridges in the magnetic tape library.

A computer-implemented method for operating a storage system comprising a file system for managing a data object in one or more storage blocks may be provided. The method comprising receiving from a file system manager a message indicating that the data objects is to be encrypted, determining, in response to the received message, a set of unallocated storage blocks that were previously allocated for storing at least a portion of the data object, and rendering content of the unallocated storage blocks of the set unreadable.

Securing deallocated blocks in a file system

A mechanism is provided for storing data files in a file system. The file system provides a plurality of reference data files, where each reference data file in the plurality of data files represents a group of similar data files. The mechanism creates a new data file and associated the new data file with one reference data file in the plurality of data files thus defining an associated reference data file of the plurality of reference data files. The mechanism informs the file system about the association of the new data file with the associated reference data file. The mechanism compresses the new data file using the associated reference data file thereby forming a compressed data file. The mechanism stores the compressed data file together with information about the association of the new data file with the associated reference data file.

Storing data files in a file system

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.

Data processing apparatus and method

A computer-implemented method according to one embodiment includes identifying abnormal data modification characteristics at a first system, determining time data associated with the abnormal data modification characteristics, and adjusting an instance of backup log data stored at a second system, utilizing an identification of the abnormal data modification characteristics and the time data associated with the abnormal data modification characteristics.

Adjusting backup data in response to an abnormality detection

In an approach to maintain data integrity in a computer data storage system, a clone management table is generated for a clone file tree that includes a relationship between at least one parent file and a clone file. The parent file is restored by: (i) determining that the parent-child relationship exists between the parent file and the clone file based on an entry in the clone management table, (ii) restoring data blocks in the parent file to the file system based on an analysis of an entry in the clone management table for the parent file and an identification of data blocks included in the clone file, and (iii) generating a new instance of the parent file based on the data blocks included in the file system and the entry in the clone management table for the clone file tree.

Clone file backup and restore

Embodiments of systems and methods are provided for data storage in a tiered storage system comprising at least two storage tiers. A method comprises: providing storage information for each storage tier of the storage tiers to a user. The storage information comprising values of storage parameters, wherein the storage parameters comprise at least one of a storage quota limit of the user, usable storage capacity in the tier for the user based on the storage quota limit, and consumed storage capacity of the tier by the user. The storage information is used to move data between the storage tiers.

Quota controlled movement of data in a tiered storage system

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.

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.
