Abstract:
In general, the invention relates to replicating a source file system stored on a first memory by obtaining a first unread entry from a changelog associated with the source file system, querying the source file system using the first unread entry to obtain a current first object file status, a current first object file path, a current first parent directory status, and a current first parent directory path, determining, based on the querying, whether a first object file on the source file system has changed at some time after the execution of the first unread entry, if the first object file has not changed, performing a first action on a target file system, and if the first object file has changed, performing a second action on the target file system.
