Thanks to everyone who has responded.

Pete, you are absolutely right. this isn't something I would propose in any environment that was in anyway important or business critical. It was more of a technical question on whether it was possible to achieve it without ongoing maintenance in the event a datafile etc was added.

Many thanks for the pointers to DBMS_FILE_TRANSFER, i hadn;t thought of that as an option, tending to always use RMAN. For my understanding, I will give that option a try !

Regards

Neil
