System and method for replicating external files and database metadata pertaining thereto

摘要

A system and method for replicating files in a source file system that is linked to a source DBMS which stores metadata pertaining to files in the source file system. The files and metadata are replicated to a target system having a target file system linked to a target DBMS. File references are also mapped from the source to the target. Also, only the most recent consistent version of files that have changed at the source and that have had insert or update references in the source DBMS are copied over to the target file system, thereby minimizing unnecessary replications.
