Re: Backup Performance

 Charles:

This is true if the hardware is doing the encryption.  One has to wonder 
if the hardware (in the case cited in the thread LTO4 with Fibre is 
capable of hardware encryption) or software was actually doing the 
encryption.  That is entirely in the set up.  I've been at customers 
where both were happening.......  they did not know it and we stopped 
software, thing got much faster after that.
