Maybe you can toggle the nice factor for your backup app, so it will  
not get in the way. (man nice)

it is a Mac OS X featuer. You can use DiskUtility to create a RAID,  
even from extern drives.

I can not recommend this, as you can only do a "real time mirror". If

You can connect to an IMAP mailserver an sync your emails to/from it.  
This way you have access to your email from everywhere.
