What is hot clone?

Hot clone, also called online clone, or live clone, allows you to clone the system when your OS is still running no matter on a physical or virtual machine. That is to say, your workflow won't be forcibly interrupted or shut down, making you don't have to wait until the clone process finishes. This helps you save time and energy.

The only problem is brought by its merits: you are able to make the operations on your computer even the hot clone process is ongoing. Therefore, the new changes during this process will not be included to clone target.

Which one is better: hot clone or cold clone?

Opposite to hot clone, cold clone is another method of cloning, which doesn't allow you to use your computer unless the clone process stops. How long it will take to clone a drive depends on how much your system data is.

Contrasting the two clone approaches, hot clone wins in the aspect of high efficiency and productivity. If possible, hot cloning your system is a better choice.

Why need to hot clone?

We have known the promising aspect of hot clone, but why do we need to hot clone? What benefits can be brought through cloning or copying system? Actually, it's a good decision to clone system if you find you are in the two following conditions:

▶ Keep your system safe: By cloning your system, you can get a duplicate of your current system data. Thus, you can restore your system or reboot from the cloned disk if some system errors like EFI partition is raw happen in the future.

▶ Optimize your OS performance: You can migrate your current OS to a larger disk or a new SSD (solid state drive) without reinstallation to improve the speed of hard drive to get better performance.
