You should probably enable block change tracking.
This allows Oracle to track changes to the database so that
RMAN does not scan the database looking for changes to
the database for incremental backups, but just reads the
BCT file and backs up the blocks pointed to.
It is very fast, and timeouts should no longer be an issue.
For the benefit of anyone reading this thread after the fact, Roy reported
that use Block Change Tracking reduced the incremental backup time
from 4-6 hours to 15 minutes.
