Yes, though I must caution you, while technically it is a logical backup, using export utilities and calling it a backup will get you flamed in some places. Oracle DBA's usually call a transactional backup a backup, and everything else not a backup, which in a practical sense these days means archivelog mode and RMAN hot backups. One big exception is if you are recreating the data every time from somewhere else that is backed up. Since that sounds like your situation, maybe you can clone that process? Just another thought.
Data Pump does have a network option, if you have proper connectivity.
