[QUOTE="Rod, post: 1841899, member: 204485"] One of the great advantages of CCC is the "reverse" cloning option. If you need to replace an internal HD, as my wife once did, you can run the device off the clone then when the new HD is installed simply reverse the process cloning your external drive back onto the new internal HD. This can be done with Time Machine too but requires a few more steps. Where Time Machine really shines is its unique User Interface (UI) that allows easy visualisation of incremental backups over time and its familiar finder file structure allowing easy navigation to the file you wish to restore. In my mind a combination of TM and CCC is ideal. If you accidentally trash or delete a file TM makes for easy restoration. If you need to repair/replace your HD or boot from a different source CCC is ideal. Lastly a bootable macOS installer can be a real advantage. I keep a USB thumb drive with a bootable macOS installer of the previous and current macOS. This is the easiest way to revert to the previous operating system if something goes wrong during the upgrade and it is not susceptible to corruption like a backup. It is easily created using an app such as Install Disk Creator and the macOS installer downloaded from Apple before you perform the update, or if you perform a new CCC backup prior to running the upgrade installer (always a good idea I think) you will have a copy of the installer you can use because the one on your device will be deleted after upgrading. I did this with Mojave when I upgraded to that and another when I upgraded to Catalina. This handy little tool overcomes one of the biggest problems people face if for some reason they want to revert to the previous macOS. Apple removes the previous macOS when a new macOS is released. And second, you cannot install an older MacOS over a new one. You can however if you erase the HD. This little thumb drive allows you to run Disc Utility to erase, format, and map the drive and reinstall the OS you have saved. You then can restore all of your data as part of the process from a backup, either TM or CCC. Alternatively you can selectively restore your data from your backup using drag an drop which is essentially what is called a "clean" install. The three methods make for a pretty solid backup system, it's what I use and recommend. Sent from my iPhone using [url=http://r.tapatalk.com/byo?rid=95677]Mac-Forums[/url] [/QUOTE]
