Abstract

This article describes techniques that are used by operating systems to provide automatic recovery from damage to off-line media when it is encountered during object loading on systems with object-oriented architectures. Encountering of damaged objects does not halt recovery as in prior systems. Objects physically located after a damaged object are successfully loaded. In computer systems with object-oriented architectures, files containing one or more objects are written onto off-line media during backup operations. When damage to an off-line medium is encountered while attempting to load a group of objects onto the system from that medium, automatic recovery by the operating system is performed to allow any objects that are physically located after the damaged portion of the medium to be loaded successfully.
