Hey OMV Guru's, quick question for your all.
So, I'm planning on having a few external USB drives (HDD's) to backup my central stuff on my OMV server, one external drive per one internal drive, so the external is an exact replica of the internal.
My question is this.
If I go down this route, is OMV/USB Backup using /dev/ identifiers or UUID's? Since I will be using multiple drives what I don't want to happen is two or more external drives (only one drive will be connected at any one time) to end up with the same /dev/sdx identifier and thus overwrite whatever is on disk B because it thinks it's disk A.
