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.
