Driver Backup is a Free and Portable Driver Saving Tool offered by Dave Hope. It can be used to backup your hardware device drivers on a Windows PC, making it easy to reinstall those drivers in the event of a format and reinstall. This tool does appear to be portable, but requires Microsoft .Net 2.0 Framework to run.
This Driver Backup Tool shares the same name as another reviewed Driver Backup Utility (can be confusing).
