I'm looking to backup my OMV OS that's sitting in a 128GB NVME to a USB drive.
I've tried to use Clonezilla to clone the NVME to the USB. Clonezilla is able to clone the image to the USB without problems -- image is way less than 16GB. I tried restoring the same image on a Virtualbox and Laptop and the Clonezilla restore process finishes and after I reboot it says that there's no OS installed.
I get two warnings during the Clonezilla restore (see attached images) and I don't know if that's what's preventing the restore or if it is caused by the fact that the USB needs to be the same size.
So, my question is: is there a way to back up the 128GB NVME to the 16GB USB or do I NEED a 128GB external SSD/USB/HDD?
Thanks in advance for the responses.
