ABSTRACT:
In an automated information storage and retrieval library system having a single recording drive, a backup or copying operation is preferably performed in a single-threaded fashion whereas in a library having two or more drives, a multi-threaded approach is preferred. The present invention provides a library with the capability to back up information from one piece of media to another in an adaptive fashion. A determination is made whether there is one drive unit available in the library or whether at least two are available. A multi-threaded backup approach is employed if there are two available recording drives in the library and a single-threaded approach is employed if there is only one available drive. In addition to making the determination when a copy request is received, the library controller can make the determination at various stages of a copy operation and adaptively change between single-threaded and multi-threaded approaches.
