I am currently using a 2011 AirPort Extreme and have been told that Time Machine backups should be on a dedicated drive. Is this still the case? If the drive was formatted into two 1TB drives, that may not be the best for TM backups, correct?
If I use the entire 2TB for TM backup and use external drives for CCC, that should be easy??
IMHO it adds nothing..
TC is for Time Machine backups. Otherwise you are doing just fine with the Extreme and Express. I see no advantage for backup over what you have already. So there is no overwhelming case for it.
