Windows 7 Backup EXTREMELY slow

[Hirorir]

I am using Windows 7 Ultimate x64.
I recently started a backup of a 314 GB (292GB used) partition to an external hard drive (500GB USB 2.0).
This is my first backup using Windows 7.
So far, it has taken 33 hours, and the bar reads only 50%. It isn't stuck, but the process is going through VERY slowly.

What's the issue, and is there a fix for it?
