Windows 7 Acer 5251 with Windows 7 Home Prem. 64 bit edition won't allow me to change where i backup my comp

[Dickcl4]

I was attempting to backup my Acer 5251 Windows 7 Home Premium- 64 bit edition when I was trying to change the settings. Everytime i hit change settings button (with the blue and yellow shield), i get sent to the location C:\Windows\System32.

Anyone have any ideas as to why this is or how I can fix this.
