Use Buffered I/O (-r) to enable buffered I/O to the before-image file. In most cases, avoid using this parameter because it might put database integrity at risk.

Caution: A database running with the -r parameter cannot be recovered after a system failure. If the system fails, you must restore the database from a backup and restart processing from the beginning.
