I have a 6TB Raid-1 array that I want to use for Time Machine and Clones for 3 machines. The RAID is seen as one volume; Time Machine and Carbon Copy Cloner both need volumes to write to, so I need 6 volumes(?). There ought to be a way to do this, but I haven't come up with a solution. Can someone point me in the correct direction?
Thanks.
Mac Studio
If you format as APFS, you can create separate APFS volumes. I think it is now possible to set disk quotas in Disk Utility which Time Machine will honor, but you may have to set it up with diskutil in Terminal.
I don’t know how CCC will handle clones on Volumes. A clone of anything Big Sur or later will have to create data volumes for each clone.
the other way would be to partition the drive. Less flexible, though.

Barney-15E,
I believe this is the answer. Got the volumes created and TM going. Will try CCC tomorrow.
Previously, I accepted the default format, Mac OS Extended, and never went back to that decision to try something else; my aging brain struck again!!
Many thanks, and happy holidays.
