I'm about to launch into a significant exercise in assessing the 
performance and capacity of a specific
Netbackup configuration and wonder if there are tools, tips, etc on the 
best way to go about it.
Specifically, I need to assess a SUN V880 running Solaris 8, Netbackup 
4.5 and backing up directly to a
locally attached (SCSI) LTO tape library with 2 drives and 20 tapes.  

Chief metrics I need to monitor and trend include CPU busy, I/O rates to 
the tape and disk drives and elapsed time
to back up "x" number of gigabytes.

Any tips, tools, experience, etc will be appreciated.
