Is there a way to do a file backup of only the changed files, on the server, before the new ones get deployed?

I'm setting up a deployment to a test server and the deployment is now working.

What I'd like to do is create a backup folder on the server that would hold a backup of the files that are about to be updated.

The backups are needed in case there's an issue so that we can quickly revert a file if something goes wrong. It's faster to revert the files on the server and then check the code for the issue and rebuild/deploy.

Is there a way to do a file backup of only the changed files, on the server, before the new ones get deployed?
