How will a clone of the disk be useful in restoring files? Will Snow Leopard be able to mount the external drive created by Lion? Will Carbon Copy be able to restore files from a backup done on Lion to the Snow Leopard file system?

A clone is only useful if something really bad happens during the downgrade, you want to be able to recover your existing state just in case.


The only way to downgrade is to do a clean install on a formatted disk.

The clone is a safety measure, in case of failure during the downgrade you will have somewhere left to go.

Actually, Csound1, I believe the disk copy is key to the entire process. Going from Lion to Snow Leopard entails wiping the system disk. Time Machine backups done in Lion are not readable by Snow Leopard. So, the only way to complete the process and get your personal files back is to restore from a backup.

If your computer came with 10.6 and you clone it before installing Lion, you can clone back and all will work, if it came with Lion installed obviously you can not. Please note that you will still have to find a way to transfer all data created from the time that Lion was installed as it won't be on the clone.


Disk Copy is a windows command that does not create a clone, I am talking exclusively about clones!

Hey Kappy! You have helped me before and I have a quick question on restoring from a backup. I am re-installing Snow Leopard from Lion on my daughter's macbook. When SL finishes, what do I need to do to restore from her last SL back-up. The good news is that there is not a lion backup on her time machine external drive.


Thanks
