IPod Touch sync conflict

when syncing iPod it has synced calendar in both directions and put a duplicate on both iPod and Computer, no I didn`t back up make back of iPod before sync, so have restored computer to a prevoius back-up, thats ok, but how do I stop iPod from doing this again and again.
Ipod 4
Windows 7
Office 2003
Going to work and beat up on plants will check later thanks

fixed it, deleted calendar on iPod, resynced after reinstall on computer and updating events for last month. Lesson must do back-up more often
