For some reason my CCC is not avoiding duplicates, instead it's copying all files and filling up my backup disk. Any settings I can change or other ideas? This is a recent change and is driving me nuts!
Couple thoughts. If you change folders or move files on the primary drive, the target drive will re-copy them in new order. I had this happen once after I moved a bunch of really old folders into a unified old file folder. It’s a safety precaution I guess. I ended up re-copying the target drive so it matched my primary. Also if you use precise drive identification, any changes to the drive name could lead to this.
