It backups the file, and puts a warning in the log file.
If you wish to guarantee the backup of an Oracle database, I suggest using
the NetWorker Module for Oracle (NMO) which uses the Oracle RMAN utility. It
is then the responsibility of RMAN to backup the data, and for NetWorker to
receive it and write it to your backup medium of choice.
