It's a lot easier than it looks - and as a nice bonus you don't need to 
spend ages tuning it.


WRT the earlier comments about SSD data spooling: It's a BIG win if 
there are multiple simultaneous backups happening. Headseeks while 
spooling kill throughput and that's exactly what happens if there is 
more than one backup process accessing the area at once.

SSD on the database won't make much difference to backup speeds simply 
because the only thing it's going to affect is attribute despooling and 
that's only a tiny fraction of the overall backup time. It's a huge win 
for anything manipulating the database and when making dumps.
