Utilizing version control systems is very important, but if no one is backing up your version control database, you are needlessly stepping close to the brink of disaster. Most source code systems store your source code and revision histories in a database or proprietary file structure. Find out where and how this data is stored, and make sure your network support staff includes it as part of their nightly and weekly backup process. If the source code database is wiped out and you have no backup, you have no source. This is also a good reason for developers to check in their code nightly (to get code changes backed up) if they don’t have workstation-based backups.
