System and method of supporting user level file system transactions using batch rename and file clones

摘要

System and method for supporting a user-level file system transaction use cloned files of original existing files specified in the user-level file system transaction to perform file system operations on at least one of the original existing files using the cloned files, which include metadata of the original existing files. After at least one of the cloned files have been modified, a batch rename operation is executed to atomically commit every modified cloned file of the user-level file system transaction.
