Abstract
Provided are a method and apparatus configured to enable the preservation and recovery of in-progress developments and changes as they are made in a system for development of content in the event of a process or system failure. The in-progress data developments and changes may be preserved while they are created, and may then be retrieved and recovered after the system or process is recovered. The in-progress data developments and changes may be preserved while they are created, and may then be retrieved and recovered after the system or process is recovered. In one embodiment, the cache memory contents are mirrored into a memory-mapped file, providing a redundant location for cache data. In the event of a failure, the mirrored cache information is available for recovery from a file. This extra cache location can be filled and flushed as needed by the system as the cache data is stored to disk or other memory location, obviating its preservation. The invention further includes a method of and apparatus for recovering and restarting the actual process or system after such a failure. Utilizing one or both features, an application utilizing the invention may reduce the amount of data …
