Backup software that DOESN'T recopy files that have been moved but not altered?

I was doing some research online and saw this from the "AI:" > **If you're looking for a Mac backup app that avoids copying files which have simply been moved to a different location without any content changes, Carbon Copy Cloner (CCC) is widely considered the best option** as it can intelligently detect and only backup files that have been modified, not just relocated. > Key features of Carbon Copy Cloner that help with this scenario: > File level comparisons: > C**CC analyzes files based on their content, not just their location, so if a file is moved but its content remains the same, it won't be copied again in the backup.** > However, after backing up a 21 GB folder in a trial of CCC, I changed the folder structure, moving some files out of their original folders and making new ones. CCC then proceeded to recopy everything to the destination. This is the same behavior I get from Chronosync, which I already own. Does anyone know if CCC can do what the AI claims? If not, *are* there any backup apps that won't recopy hundreds of gigabytes of information if I happen to rename a folder containing... hundreds of gigabytes of information?
