Abstract
Method, system, and apparatus for maintaining consistent images of metadata and data in a file system or other data journaling software stored on a temporal volume are presented. An intent log is maintained of all data and metadata modifying transactions, which is then relayed either asynchronously or form a last known consistent checkpoint to a requested checkpoint thereby rendering the requested checkpoint data and metadata consistent.
