To quote SAP

util_file_online : (if supported by the manufacturer of the external backup
program) backup or restoration is made file-by-file using an external
backup program addressed by the BACKINT interface. The backup status is
also set and ended dynamically for the tablespaces to be saved in an online
backup.
The parameter util_file allows you to use other storage media (e.g. optical
media), provided the supplier provides corresponding backup programs and a
BACKINT interface. In such cases, the SAP utilities can call the external
backup program for the physical backup or restore of the corresponding
files. If parameter util_file_online is used, the volume of offline redo
log files is also drastically reduced during an online backup
