Gives a SQL command to refer to Oracle, on a tablespace-by-tablespace basis, that the folders of the tablespace are to back up. The users can continue to create full use of the files, including creating modifications to the data. Once the user has refers that he/she wants to back up the files, he/she can need the operating system to copy those files to the right backup destination. The database has to be operating in ARCHIVELOG mode for the hot backup option.
