Well, depends what you mean here. Surely, you need to unmount the drive from the server which serves the partitions... But that is single piece of hardware and you need not to shut it off, just unmount the drive. And that can be done by script automatically at appropriate time or manually very easily.The one glaring issue, is that I also want to keep a backup off site. Ill look into those two options, but to keep it automated and to use CCC, I would have to unmount all the CCC backup drives. Shutoff the mac server.
