CyArc - File Archive and Recovery 1.1   
by CyWarp   

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 to keep copies of digital photos as you work on them or to create copies of files in an important project as you develop it. Alternatively you can simply set it up on your My Documents area to copy each new file you create or update. If you have two disks you can use CyArc to make its copies onto a separate disk so in the event of a hard disk failure you have copies of updated and new files. The output is suitable for both backup and archive.
