Abstract: 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.

Abstract: Generating backup sets for a specific point in time from backup data stored in a backup storage device is provided. A backup set, in accordance with an illustrative embodiment, is a collection of the files and data that would have been the most recently backed-up version of a computer's files and data at the particular point in time if the backup set had been created at that point in time. In order to generate the backup set, versions of data objects are identified in the backup storage system that have backup timestamps equal to or prior to the designated point in time and that have deactivation times that are after the designated point in time. In addition, a mechanism for deleting versions of data objects based on a retention time and an inactive version limit is provided.

Abstract: Provided are a method, system, and article of manufacture wherein one client node is selected from a plurality of client nodes. A determination is made that an object corresponding to a client node has to be stored. A determination is made as to whether the object has already been stored in the server node by the one selected client node. The object is stored at the server node, in response to determining that the object has not already been stored in the server node by the one selected client node.

Abstract: Mechanisms for enforcing change control in operations performed by operational management products (OMPs) are provided. The mechanisms automate the checking of a request-for-change (RFC) state by an OMP when the OMP is installed in an environment where a change management database (CMDB) has been installed and certain resources or operations have been placed under strict change control. The OMPs of the illustrative embodiments require an RFC identifier to be specified when a change operation of the OMP is invoked. The RFC identifier is used by the OMP to access a service management system so that the OMP may determine if the RFC identifier is valid, IT resources are in the correct state, and the change is scheduled to be performed at the current time. If these checks are passed, then the change operation associated with the RFC is permitted to occur.

Abstract: A copy procedure detects qualified data objects in a body of source data, and copies the source data to a target storage unit except for unqualified data objects, which are replaced with a prescribed bit pattern. Following completion of the backup, a record is prepared indicating that all data objects exist in the specified target storage, regardless of whether each data object was replaced with a predetermined bit pattern rather than being physically written to the specified target storage. This process may, be repeated in order to perform data reclamation, effectively removing user files no longer qualifying for backup.

Abstract: A method and system are disclosed for transparent backup to a hierarchical storage system. A data management application requests a backup operation, communicating the request using the Network Data Management Protocol with a tape server and a data server. The tape server generates a unique identifier for the data set. In addition, the tape server transfers the data set from the data server to the hierarchical storage system and sends the identifier to the data management application in response to the request. The identifier identifies the data set within the hierarchical storage system. In a certain embodiment, the tape server stores and manages the data set in locations transparent to the data management application. The tape server and data management application may be logically distinct. The data management application may access the data set through the tape server using the identifier.

Abstract: A system, apparatus, and process creates a table of contents (TOC), including one or more table of contents (TOC) entries, to manage data in a hierarchical storage management system. Each TOC entry contains metadata describing the contents and attributes of a data object within an image, which is an aggregation of multiple data objects into a single object for storage management purposes. The TOC is stored in a storage hierarchy, such as magnetic disk, for fast access of and efficient operation on the aggregated TOC entries. The system, apparatus, and process also provide for aggregating the TOC entries from one or more TOCs into a TOC set in the storage management server database. The TOC set may be manipulated and queried in order to find a particular data object or image referenced by a TOC entry.

Abstract: Provided are techniques for space recovery with storage management coupled with a deduplicating storage system. A notification is received that one or more data objects have been logically deleted by deleting metadata about the one or more data objects, wherein the notification provides storage locations within one or more logical storage volumes corresponding to the deleted one or more data objects, wherein each of the one or more data objects are divided into one or more extents. In response to determining that a sparse file represents the one or more logical storage volumes, physical space is deallocated by nulling out space in the sparse file corresponding to each of the one or more extents.
