How do I backup a database?

Hi,

I have a small system using a Personal Oracle7 with some twenty tables of data. Inorder to accomplish a very simple version handler which keeps track of different versions of the data I would like to make a copy of the entire database. The question now is, can I do that by using SQL statements? I've looked in the manuals but I don't really understand if it's possible, or if it is, how I do it... (tablespace?, backup begin/end?, ...)  

Thanks,

Pontus
