Running OMV 6.0.25-1 (Shaitan)
OMV has a file system that needs updating from a portable HDD that I pack in my suitcase. That drive is attached and mounted. I want to overwrite the existing files and directories on the NAS with the files and directories on the portable HDD. IOW, deleting everything on the NAS and copying everything over from the HDD.
I could use ssh command line, or mc, or rsync . . . I'm not sure what is the best way to go about this. OMV ain't straight Linux and I don't want to break anything. How might I go about this?
