How to backup a flash drive automatically each time I plug it in?

I remember using a program to do this in the past, but I can't find it anymore.

Regardless of that, in Windows is there a way I can automatically backup a USB flash drive each time I plug it in?

Solution 1:

Please ask for product recommendations on the appropriate forum Software Recommendations.

Rewrite to match @techie007's edit of the question:

The easiest way to do an automatic backup when plugging in a USB flash drive is to use a 3rd-party tool such as Syncback. This detects drives being connected and can also detect specific drive ID's and run backups accordingly.

While it is also possible to do this by monitoring Windows Management Interface (WMI) events, I wouldn't recommend it for doing backups as the possibilities for error - and therefore the backup failing - are significant.
