metadata journaling

Metadata journaling is a process used by computer file systems to keep track of changes to files and directories. When changes are made, such as creating, modifying, or deleting files, the system records these alterations in a special log or "journal." This helps ensure that if the system crashes or encounters an error, it can recover the most recent and accurate information about the files. By maintaining a detailed record of changes, metadata journaling enhances data integrity and minimizes the risk of data loss.
