version controlling

Version control systems are a category of software tools that help a software team manage changes to source code over time.
Version control software keeps track of every modification to the code in a special kind of database. If a mistake is made, developers can turn back the clock and compare earlier versions of the code to help fix the mistake while minimizing disruption to all team members.
