Hi, sorry for piggybacking on to this thread but I came looking for a way to do just this, clone my installation drive onto a USB drive before i do a wipe and clean install but was worried that I might need to recover. Anyway... I'm a complete noob who setup OMV using some guides many years ago. Could you share how I can do a clone of my OS drive onto a USB. I've read about clonezilla and also something about a backup plugin but both assumed I create a folder on one of my data drives.
Any help would be appreciated!
My script also requires a folder on one of your data drives as a target for the backup/clone. And you will have to mount it as well. After that, a cronjob for a nightly backup is quite easy. My current script (as you can see, there are still some old changes visible).
