CCC will then wipe anything on the CCC partition but leave you other data on the second partition in place. on one partition and use the other for CCC. S the answer to your issue would be to make two partitions on the external drive. In short - I want to know if I need to purchase a new external, purely for CCC - or can I continue using the existing external, that already has data on it.ĬCC will overwrite anything on the volume/partition you use as the destination. If I unplug the External, and pop it into my MBP - and then point CCC over to it, does CCC create a new folder and automatically place the single(?) disk image onto the External? Does it continue to overwrite that single(?) disk image, each time it clones - or does it gradually fill up the disk, as TM appears to?

I have an external 1TB drive connected to our router, that we use to store backup copies of family photos movies etc. Question: Can CCC use an external drive that already has data on it - without wiping that data? Or does it work in similar fashion to TM, that needs a "clean" disk to write too? Apologies for this incredibly noob question - but having looked around at various places, including CCC's help files - I cannot find any confirmation
