On Mac OS X you can not move the System files the same way you could on Mac OS 9 to make a backup copy.

However, you can use Clone X.

Using Clone X:

The interest is mainly to clone system and application, otherwise  installing from the original CD would be faster!

The system has been cloned from source on a third disc.
Then when you restore no application (aside clone X) must be opened!
Ensuite après la restauration avant de redémarrer :

Then after the restore before rebooting:

- In the 'finder' choose 'Preferences' and check Always show file extensions

- Copy BEFORE restarting the User folder with All the USER's from the original disk, you can remove them later. If some files aren't copied for user rights reasons, put the file permission to your current User (yours) and then copy the file and then put both files (the source and copy) with the original permissions.

- Open Disk Utility and make a correct permissions on the new disk restored.

- In Disk Utility do a repair with Disk Repair

- Before restarting the device name must be the same as the source disk, however, two discs do not have the same name, so use a temporary name for the source disk. Especially for some third party applications that do not support the renaming of the disk relative after installation.
