CyArc takes copies of files as you create and change them. Multiple versions of files are kept reflecting the history of file changes. When you use CyArc on a set of folders you are in the position to go back to any version of a file. You can use it on you're my Documents area to get copies of files as you work on them or set it up to track changes to digital photos or an important project. The output is suitable for both backup and archive.
