I believe so. If you use rman to take an Oracle incremental level 1+ backup, Oracle does the work to work out what data to send. It sends its data over the SAN rather than IP which should improve performance. If you use block level incremental backups then it should improve performance by only reading the changed blocks. That's my understanding anyway.

No, you do not need Advanced Client to take incremental backup. - What is the additional benefit by using Advance Client BLI in the oracle type backup? According to the Netbackup manual; saves time, less backup media, reduces CPU and network overhead.
