A high availability, high reliability storage system (215) that leverages rapid advances in commodity computing devices and the robust nature of internetwork technology such as the Internet (213). A system of parity distribution (505) in accordance with the present invention allows for greater fault tolerance and levels of storage efficiency than possible with conventional RAID (levels 0-5) paradigms. Data can be recovered or made available even in the case of loss of N, N+1, or more devices or storage elements (215) over which stripes of the data set have been distributed or partitioned. The present invention provides a parity distribution that can be used to distribute data stored in a single storage device or across multiple connected or otherwise networked devices.

In a computer having one or more secondary storage devices attached thereto, a Finite Data Environment Processor (FDEP) manages Data Sets residing on the secondary storage devices and in memory using Set Lists (SLs) and General Record Pointers (GRPs). The Data Sets contain either data or logical organizational information. The Set Lists comprise Data Sets organized into a hierarchy by listing a identifier for each of the data sets with a corresponding identifier for the logical parent of that data set. These set lists are also data sets and can be identified as child or parent in a set list. The General Record Pointers identify information in terms of Data Sets and records within them. Using the principal idea that a Data Set is uniquely identifiable, the present invention eliminates problems normally associated with referencing the location of data after the data has been moved.

Systems and methods are disclosed for performing data storage operations, including content-indexing, containerized deduplication, and policy-driven storage, within a cloud environment The systems support a variety of clients and cloud storage sites that may connect to the system in a cloud environment that requires data transfer over wide area networks, such as the Internet, which may have appreciable latency and/or packet loss, using various network protocols, including HTTP and FTP Methods are disclosed for content indexing data stored within a cloud environment to facilitate later searching, including collaborative searching Methods are also disclosed for performing containerized deduplication to reduce the strain on a system namespace, effectuate cost savings, etc Methods are disclosed for identifying suitable storage locations, including suitable cloud storage sites, for data files subject to a storage policy Further, systems and methods for providing a cloud gateway and a scalable data object store within a cloud environment are disclosed, along with other features

An archiving file system is specifically designed to support the storage of, and access to, remote files (42) stored on high speed, large capacity network data servers (14). The archiving file system automatically archives remote files (42) across multiple types of secondary storage media (46, 48) on such network data servers (14), based on a set of hierarchically selectable archival attributes selectively assigned to each remote file (42). The archiving file system is completely transparent to the user program (22) and operates on remote files (42), by providing a different file control program (40) and a different file structure on the network data server (14), without the need to modify the standard file system (24) that is native to a particular operating system program (20) executing on the user nodes (10) or the standard network file interfaces (34) executing on the distributed computer network environment (12).

Systems and methods for data classification to facilitate and improve data management within an enterprise are described. The disclosed systems and methods evaluate and define data management operations based on data characteristics rather than data location, among other things. Also provided are methods for generating a data structure of metadata that describes system data and storage operations. This data structure may be consulted to determine changes in system data rather than scanning the data files themselves.

A data storage hierarchy which inherently allows for a level 1 storage file to be uniquely identified across an entire network is disclosed. A directory naming convention is employed which includes an internal identifier and a name for each subdivision of the network. Because each file can be uniquely identified across the network, a single level 1 storage space in a file space, or a directory therein, can be used for the entire network. Also, because of the inherent uniqueness of the naming system, common DASD control files otherwise required to map between level 1 storage files and their level 0 source files can be eliminated.

Techniques for adjusting the frequency of data backups and initiating event-driven backups in a storage system are disclosed herein. In one embodiment, a self-adjusting backup frequency, known as a “Change Rate Objective,” is defined to conduct or delay backups for one or more volumes in the storage system on the basis of an associated policy value. The Change Rate Objective may be tied to one or more business or data activity events, such as the amount and type of data changes since a last backup. The storage system may also be tailored to conduct or delay full or incremental backups on the basis of a Change Rate Objective that measures whether a full or incremental or differential backup is more appropriate. Various data or system failures, or data or business events may also be used to adjust the retention periods of continuous data protection (CDP) data and delay a rollup of CDP data.

A first file system to assist in the storage management of a second file system not able to store its own management classes and management attributes. A repository file space in the first file system is used to accomplish the storage of some or all of the management classes or attributes for the files of the second file system. For each file in the second file system an empty file is created in the repository file space of the first file system. The creation of an empty file in the repository file space causes a management class to be selected for the file and stored in the catalog of the first file system as would be done for any file in the first file system. A naming convention is used to link each file in the repository file space with its associated file in the second file system. The additional files in the first file system are left empty as no other information need be stored for storage management purposes. The management attributes of the files are then compared to the management criteria represented by the management classes stored in the catalog of the first file system and the files are managed accordingly.

A method and system for integrating migration level two (ML2) and backup tape processing provide for the backup, archival, and/or restoration of ML2 tape files without the use of tape mounts. In this manner, the amount of data movement required to recover from data loss is significantly reduced. Tape files may be recovered to their original status, even if the file has migrated to ML2. The status of the data is preserved after such a recovery operation. In this manner, data movement is reduced because no remigration of data is required after a recovery.

The invention provides an improved SAN of type having one or more host digital data processors, coupled to one or more storage devices. At least a selected one of the hosts includes a file system that effects access by the host to assigned storage devices. This can be, by way of non-limiting example, an AIX journal file system, a Veritas file system, a Unix file systems using Veritas volume manager or other host platform file system that oversees file and other data accesses between the host and those assigned devices. In response to a request by (or on behalf of) the selected host for extension of the file system, a manager (e.g., executing on a further digital data processor) assigns one of more further storage devices to that digital data processor. An agent associated with the first digital data processor that responds to the assignment by extending the file system to include the assigned storage device.
