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 and process time lost as a result of a process or system failure.

Claims

1. A method of 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, comprising,

retrieving in-progress data developments and changes while they are created and storing them in a cache memory;

copying cache memory contents into a memory-mapped file, providing a redundant location for cache data;

in the event of a failure, recovering the cache information from a file;

flushing the memory location from the memory mapped file as needed by the system;

and recovering and restarting the actual process or system after such a failure.
