The Open Group

The Open Group is the leading vendor-neutral, international consortium for buyers and suppliers of technology. Its mission is to cause the development of a viable global information infrastructure that is ubiquitous, trusted, reliable, and as easy-to-use as the telephone. The essential functionality embedded in this infrastructure is what we term the IT DialTone. The Open Group creates an environment where all elements involved in technology development can cooperate to deliver less costly and more flexible IT solutions.

Formed in 1996 by the merger of the X/Open Company Ltd. (founded in 1984) and the Open Software Foundation (founded in 1988), The Open Group is supported by most of the world's largest user organizations, information systems vendors, and software suppliers. By combining the strengths of open systems specifications and a proven branding scheme with collaborative technology development and advanced research, The Open Group is well positioned to meet its new mission, as well as to assist user organizations, vendors, and suppliers in the development and implementation of products supporting the adoption and proliferation of systems which conform to standard specifications.

With more than 200 member companies, The Open Group helps the IT industry to advance technologically while managing the change caused by innovation. It does this by:

The Open Group operates in all phases of the open systems technology lifecycle including innovation, market adoption, product development, and proliferation. Presently, it focuses on seven strategic areas: open systems application platform development, architecture, distributed systems management, interoperability, distributed computing environment, security, and the information superhighway. The Open Group is also responsible for the management of the UNIX trademark on behalf of the industry.

The Development of Product Standards

This process includes the identification of requirements for open systems and, now, the IT DialTone, development of Technical Standards (formerly CAE and Preliminary Specifications) through an industry consensus review and adoption procedure (in parallel with formal standards work), and the development of tests and conformance criteria.

This leads to the preparation of a Product Standard which is the name used for the documentation that records the conformance requirements (and other information) to which a vendor may register a product.

The "X" Device is used by vendors to demonstrate that their products conform to the relevant Product Standard. By use of the Open Brand they guarantee, through the Open Brand Trade Mark License Agreement (TMLA), to maintain their products in conformance with the Product Standard so that the product works, will continue to work, and that any problems will be fixed by the vendor.

Open Group Publications

The Open Group publishes a wide range of technical documentation, the main part of which is focused on development of Technical Standards and product documentation, but which also includes Guides, Snapshots, Technical Studies, Branding and Testing documentation, industry surveys, and business titles.

There are several types of specification:

In addition, The Open Group publishes:

Versions and Issues of Specifications

As with all live documents, Technical Standards and Specifications require revision to align with new developments and associated international standards. To distinguish between revised specifications which are fully backwards compatible and those which are not:

This Document
This Backup Services API (XBSA) document is an Open Group Technical Standard. First, it presents an architecture for management and client applications which use the services of underlying backup and archive software. It then specifies a Backup Services API consisting of source procedure calls, type definitions and data structures, and return codes, to be used by these management and client applications.

The focus of this API is on defining backup services for data movement, as opposed to management, with an emphasis on retaining programming flexibility so as to ensure broad applicability. The programming model used aligns with the widely accepted open/read-write/close model.

Background information is included, which is intended to be of particular value to end users and vendors, covering the use of this API, and consideration of the wider issues involved in backup, archive, and restore operations.

Intended Audience
This Technical Standard is intended for three types of user:

  1. Application developers who wish to write portable programs that use the backup service operations defined in this Technical Standard. Typical applications or end-user services would be databases, filesystems, document managers, and object managers.

  2. Developers of management applications to manage the operation of backup services defined in this Technical Standard.

  3. Developers of the actual backup services packages which carry out the functions of this Technical Standard. These services are provided to higher-level management applications or client programs.

The structure of this Technical Standard is as follows:

A Glossary and Index are also provided.
