If OP is doing the traditional export, the little used option resumable can be set to Y to prevent abort on space-related errors. If it's expdp, there's no such parameter because expdp does it automatically, and shows on screen "ORA-39171: Job is experiencing a resumable wait" (except during the final index creation phase). Also gone with expdp is resumable_timeout so it gives you only 2 hours' time to respond. But I think you can create a logon trigger for the user doing expdp to set it.
