Hi Guys,
Thanks for getting back to me.

H: is a mounted drive, it's the E drive from the live server which is where I store my dumps, I guess it would also help for me to show you how the file is dumped:

set oracle_sid=ezt1
exp80 system/manager file=e:\backup\ezt1.dmp grants=y indexes=y rows=y constraints=y log=e:\backup\ezt1.log full=y

I know in this case that I should really only be doing a user export, but I have little Oracle experience nor time to look into how to do one. I might ask about that later if that's OK.

I'm using at to schedule the dump, as you can see it dumps from the system user.

Any help will be great!

Cheers,

Mark
