10.4: How to run Carbon Copy Cloner
Authored by: rpaul on Jun 17, '05 12:17:21PM
An alternative method for a straight clone is to use 'asr' from the command line. e.g.:
    sudo asr -source / -target /Volumes/firewireBU -erase
where the target path is to a mounted backup partition.

The -erase flag will bless the copy (so that you can boot from it) but obviously erase the previous contents of the backup partition.

Use with caution and check out the man pages for use of asr.

Personally I'm looking forward to CCC being updated soon.

Disk Utility is potentially faster
Authored by: Froderick on Jun 20, '05 12:20:37PM

Actually, Disk Utility has a built-in block-level copy cloner that my tests have shown to be faster and more efficient than CCC.

Running CCC, in my lab-cloning experience, effectively prohibits multitasking on the machine in question (although making any changes to the filesystem during cloning is highly suspect in general). It sucks up MASSIVE system resources and more or less removes the interactive interface. I can barely move the program window around because it takes so long to register keyboard/mouse input.

Disk Utility in Panther or greater has this built in feature, in the "Restore" tab. Select any drive in the list (I don't think it actually matters), then drag a drive or disk image (I haven't gotten it to work properly the way I wanted with disk images, but for pure CCC replacements, a disk-disk transfer is easiest) into the Source Field, your destination disk into the Destination field (surprise!), check the "Erase Destination" box (otherwise it won't use block-level copying), skip the cheksum if you want (though not recommended for the first few clones or any critical data/operation), and click the "Restore" button.

This is preferable to me because it works out of the box without needing any network connections or separate devices to transfer CCC over. Every Apple computer will come with this, so I don't need to take one machine out of a new shipment, set it up first the way I want, and then do a transfer; I can take a pocket Firewire drive and hook it up directly and begin copying and transferring immediately with little to no lag time. From there I can start daisy-chaining.
