Course Introduction：Common reasons for MySQL backup failure include script errors, MySQL service exceptions, insufficient disk space and unrecoverable backup files. 1. Check whether the backup script or command is correct, ensure that the path, permissions and syntax are correct, and run the script manually to troubleshoot errors. 2. Confirm that the MySQL service is operating normally, check the connection status, network paths and firewall settings, and check the error log to locate the problem. 3. Check the disk space and file system, clean old files or expand storage, and use df-h and fsck to troubleshoot space and file system problems. 4. Periodically test backup file recovery, verify backup integrity, and select appropriate backup parameters to ensure recovery capabilities. The backup must not only be successful, but also ensure it is recoverable.
