EuresTools Versioning is a secure version control system for managing files and directories, which is based on Open Source tool Subversion. A tree of files is placed into a central repository. The repository is much like an ordinary file server, except that it remembers every change ever made to your files and directories. This allows you to recover older versions of your data, or examine the history of how your data changed. Subversion can access its repository across networks, which allows it to be used by people on different computers. Because the work is versioned, you need not fear that quality is the trade-off for losing that conduit - if some incorrect change is made to the data, just undo that change
