I understand my question must have been recently installed OMV 5 and I want to back the system disk.
I understand there are 2 main options:
But I can get it working.
1. I tried Clonezilla, installed from extra, reboot and used the GUI. The clone failed (with 2 different disks).
2. I installed the backup plug in from extra but apparently can only backup shared folder.
Apologies if my questions are basics and of course I tried hard with the search top-right but I'm stuck. Can anyone give me some help?
