How does journaling improve the reliability of a file system?

  • Improves file compression
  • Prevents data loss in case of system crashes
  • Reduces disk space usage
  • Speeds up file access
Journaling in a file system involves recording changes to data in a journal before actually writing them to the main storage. This technique enhances reliability by preventing data loss in case of unexpected system crashes or power failures. When a system crashes, the journal can be used to replay transactions that were not yet committed to the main storage, ensuring data consistency and integrity. As a result, journaling helps maintain the reliability and consistency of file systems, making them more resilient to failures and ensuring data integrity.
