Nico's Backup will automatically archive specified files and folders into a single ZIP file. It can:

Write this ZIP file to disk (local or networked harddisk, floppy disk, Zip or Jaz drive, CD-Rewritable etc);
Send the file to an FTP site;
Burn the ZIP file on CD-ROM (most CD-ROM drives are supported).

The built in scheduler will tell it to run backups daily, weekly, or monthly.
