Oracli,

cheery_poori asked how to do a backup. Exp/imp is not a backup method, I'm not saying it doesn't have it's uses, but it isn't a valid backup method. Rather than arguing with Davey follow this http://asktom.oracle.com/pls/ask/f?p...D:832427034486
and search for

'do not even remotely consider use EXP as a "backup" tool'

I think you can guess who said it from the link.
