Nice that you qualified that with usually. We took the same 3590 and the same controller card from a 520 to a 730 and the SAVSYS portion of the backup dropped from 44 minutes to 4 minutes. Other times were just as significant. Yes you can buy a tape drive that will require a faster CPU to drive it at rated speed. Even if the processor is in a restricted state.

Most backups are I/O intensive - not CPU intensive. In other words, your backup device and I/O processors will slow the program down before it reaches a point where CFINT might kick in. >I'm about to move to RISC. I have read about the CFINT governor.
