- Multiple copies create confusion:
- This is true that having backup is one of the most important best practices, but it should be maintained in well managed way as you can use tags like name, date and time of the backup, version, etc. If you have multiple copies of the same source code or document, then it will create confusion and it would be difficult to identify latest code or document.
- It is strongly recommended to use proper source code version control system. There are many source code version control software applications available for free (like SCCS, CVS, Subversion etc.) which you can use to store different versions of the software. But while using a source code control system, follow the rules below:
- Always take source code from the version control system.
- Always assign a new version to every change.
- Always put source code back into control system.
