I successfully imaged my O.S. internal nvme drive using Clonzilla from the kernel plugin.
Using the GUI I set boot to Clonezilla once. Then ssh into Clonezilla and selected the backup options. One of the options was to reboot the system when the backup completed. However I could not get this to work. Instead of rebooting it gave some kind of error and went to command prompt. I had to manually restart with "sudo reboot".
Any idea why this didn't work?
My end goal is to create a system scheduled task that will boot to Clonezilla once, run Clonezilla to perform a backup (with preseeded configs), and then reboot.
