Abstract: A method, apparatus, and program product restore database data having dependencies or ordering sensitivities, or that incorporates a database index. Unresolved dependencies are identified in response to an attempt to restore data in a computer. The data restoration is deferred and the data is cached when it has an unresolved dependency. After the dependency is resolved, the data restoration is completed. The unresolved dependency may be based-on data that must be restored or created prior to completing restoration. Deferred data is cached in memory and tracked in a deferred operation table. Data that is deferred may be accessed so long as operations that access the underlying based-on data are denied.

Abstract: A method, apparatus and computer program product are provided for implementing enhanced autonomic data backup using multiple backup devices. A media definition object is defined for saving predefined user selections including a default backup format to be used, an order to process the libraries, a library exception size, and a maximum number of backup devices to be used serially. A list of libraries is generated by either a user specified order of the libraries or a size order of the libraries from largest to smallest. Each library in the generated list of libraries is processed to form at least one library queue of a serial device wait queue and a parallel device wait queue. A process IO procedure is called until backup completes for each library from the at least one library queue.
