Using SQL Server 2008 R2 Resource Governor to limit CPU tap from running a FUll DB Backup

Hello -
We have a 1.1T DB that I need to run a backup of during the day but due to it's size, the CPU takes a hit and the end users report application performance issues.  This is unacceptable so I wish to use the Governor to limit how much the CPU is hit so I can run the backup.  

Is this possible?  I have reviewed BOL for R2 but not exactly seeing the help I need.

Suggestions please.

Thanks

Here's a good read on using the governor for limiting resource consumption for backups:

Thank you for the input.  No, I am not using compression for the backups.  I have also reviewed MSDN pages offered regarding the templates etc and the article from programming4.us is similar in content to the MSDN sites.  

I have the template set up but wanted to know if any has had success with running a full DB backup using the governor to lower the performance impact on the end users.

I need to pull a file back up so the db will fit onto two secured drives as it is more that 1.1 T  I just did not want to have to stay up all night to do this task.  

Ideas welcome.

Unfortunately, I don't have hands-on experience w/the governor on an actual backup.  Take a look at the whitepaper referenced at the bottom of this, the Appendix B - Resource Governor Overhead.
