Because of this hiding of used sectors in the partition, the OS and apps wouldn't know about it. Any program you used that expected the OS to accurately reflect what sectors were available would result in destroying this hidden backup store. Plus there is no control in CTM as to how much free disk space gets used by its hidden backup store. You could end up with all of your free disk space getting consumed by CTM but the OS and apps thinks there are gobs of free space available. I don't remember GoBack being this hazardous by intercepting the file I/O of the OS to use sectors for its own hidden purpose.

It's trying to be clever but it clearly violates system integrity. It's one to avoid. |
