==========
Our datawarehouse cannot turn on archiving due to performance issues.
We need a faster backup strategy, that is why I am exploring RMAN B&R.
2 concerns our application team have raised regarding the new backup strategy:
1) need less down time, faster backup
2) ability to restore the database to the required date.
=============================

You need "the best" perf team to turn on archivelog.

Why do the app team raise a concern about backup strategy? Only the DBA needs to worry about the backup and restore.

For faster backup, use EMC's BCV.

To restore the DB to a previuos time stamp, you need to turn on archivelog. I run all my DBs (dev, test, preprod, prod) in archivelog mode. No problem. I can write 1.5 GB worh of redo log files in less than 1 min.

300 GB size is a very small database in 21st century.
