A clone is an exact duplicate (identical twin) of another drive. So that doesn't seem to be what you want.
With Acronis you can make an image file of your complete sata drive 'Mybackup.tib' and store the file on your ext ide drive. You also need to burn to DVD/CD the Acronis boot disc - in the options choose the full version - which will contain the full acronis program and burn it to the boot disc.
To restore the image to a brand new internal empty sata harddrive, you put the boot cd/dvd in the tray, power down and with the pc powered off you connect your ext hard drive (that contains the backup.tib) switch ext drive on and then power up pc and boot from the Acronis disc and follow the on screen prompts.
I suggest you make more than one backup image .tib and store on ext ide drive, but that's just me, belt and braces.
If you want to clone you will have to connect your new empty sata hard drive and then choose the clone option.
