Executive Overview:
Disk Hero Carbon Copy is an automated Carbon Copy program to keep your data on multiple computers up-to-date with the latest current file information. You modify a file on your main PC and all your other target PCs are automatically updated with this recently changed file. A full copy of the main PC back up files are sent over to the target system(s) so full data duplication is realized. For example: This page you are reading is revised and becomes a changed file. This file is sent to Disk Hero's backup servers. Carbon Copy then says it is to send this new copy to 3 other computers and the Carbon Copy is complete. On the target systems you can read the files and do what you like with them but they are not sent back to the originating PC as a modified or updated file. You can set up the 2nd PC to do Carbon Copy with the first PC so both PCs are sending files back and forth making full data copies of each other. Make sure each PC has enough hard drive space.
Here is an image of how it works:
