I’ve recently used Clondzilla Live. But since I was going to a larger drive I had to resize it with gparted live. (admit it; poor planing, didn’t use clonzilla for who-knows-how-long)
GParted is a free partition editor for graphically managing your disk partitions.
It does have a copy and past (clone) option and then resize if the drives are different sizes. It’s user friendly, compared to clonzilla which is completely command line options.
Even so, when ‘they’ said my drive was dying, I used rsync which is a fancy copy, and just transferred them back after I let the tablotv re-format the drive - nothing elaborate and it worked.
Of course, it worked for me. I’m not recommending it as much as suggesting it’s an option to investigate as a possibility for you.
