Import arcpy in 10.1

I've been shuffling along on multiple threads trying to find a solution to the "import arcpy" function. I'm not a programmer or do I understand python very well. I'm essentially trying to create a model which I can run in task manager. From my limited understanding, I have to:
- Create a model in Model Builder
- Export the code as Python script
- Schedule a task in Task Manager

I've read that using different version of Python will mess with how my Python interface interacts with Arc. I currently have Python 2.7 installed along with ArcGIS Desktop 10.1. I previously had Python 3.4 installed but I read something about Arc 10.1 not being compatible with the 64-bit Python 3.4.. I'm not sure if I have any residual files messing with Python but importing arcpy doesn't work. I get the following error:
Is there a simple way to solve this problem. (Maybe a step by step?) Simply put, I want to copy files from a geodatabase to a "backup" version on a weekly basis. Maybe I'm taking the wrong approach?

Any help would be greatly appreciated.
Cheers,
Simon
