Best hard driver clone software?

[DWB]

I have a hot swappable dock that holds two drives and clones one, but the cloning feature stopped working. Made in China.

What is good for cloning a drive without having to copy the entire drive again every time you want to use it, only copying what is new on the original source drive?

Thanks.

Maybe that acronis true image can do the job for you.
