Hi Everyone,

   I just wanted to reply with a thank you to everyone who posted 
ideas.  It was definitely a database problem, and I think it was the 
attribute spooling which ended up fixing it.  I added Heitor's DB tuning 
instructions; used mysqlcheck -m/-o on my DB; and then added "Spool 
Attributes = yes" to the default job definition and backups went from 
120-130 hours down to 10.  Quite an improvement. :)
