I've not had any issues with logging or recovery that could be attributed to not using FRA.

DUPLICATE TARGET works for refreshing a database. I have at times had issues getting this to work however. That was on NBU 5.x, and were are now on 6.0 MP5. I did a DUPLICATE TARGET a couple weeks ago without issue.

Yes, in addition to Level 1 incrementals.

Quite an open ended question, anything specific you are looking for?

I can't really compare FRA to NetBackup directly, as I have not made use of FRA.

That said, there have been some quirks with using NetBackup, specifically the MML.

In either NBU 5.3 or 5.4, some changes were made to the MML that require all RMAN commands and parameters to be in upper case, unless it is something that should specifically be lower case, such as a parameter value.

Not *all* commands really, but some things don't work if not UC.

For the most part, it has been quite reliable, and has never failed in a production restore. The only 'failures' I have experience were in the DUPLICATE TARGET. I didn't feel like dealing with Symantec Support again on those issues, and just refreshed the database the old fashioned way.
