RE: Oracle RAC backup hardware/software recommendation?

Well thought out and interesting response Chris.

I am interested in your point 3.

We don't use RAC (well I don't!!) but do have occasions when we restore archived log files from the MML/Tape Robot when they were backed up on Client A and the database is now on Client B. (cluster and the databse has failed over to the alternate node). We do not have to mess around with the MML config, we just ensure that the NSR_CLIENT is set correctly and privileges are correct within Networker (or whichever MML you will be using)

Have I misunderstood your point or is it RAC specific?

...

3.) On the same note as #2 above learn now that Oracle-RMAN sees a "backup" as a whole...a single logical unit, while *ANY* MML sees individual pieces of data from a client (machine). This becomes critical when you are trying to restore *ALL* (local) arch log files at one time from two DIFFERENT clients...or you are trying to restore all the datafiles backed up from RAC-node A to RAC-node B. These are the same database and RMAN backup, but different clients as far as the MML is concerned. Server "spoofing" with MML config files is a must "know" with RAC and MML.
