I'm using a 3 Tb external drive to store old media files and for backup. I've partitioned it to 750 gb for media and a 2.25 Tb partition for backups, which I've named "Time Machine". I have Time Machine send backups to the Time Machine partition. I also use Carbon Copy Cloner every few months to clone my Mac's internal HDD into the same "Time Machine" backup partition. It's now telling me that the backup partition is completely full. When I look at the partition, I can't tell what folders are for what. Are all the Time Machine backups in "backups.backupsdb"? There are other folders: CCC Safetynet; Applications, Docs, Incompatible Software, System, etc. Are these all part of the CCC backup? Should I just delete a bunch of the old Time Machine backups?
