OK, I will not insist, I will recreate the backup again, this is anyway not a professional solution so I accept to bloat my local network for another 2 day redooing the copy back to my backup WD.
BUT, my Backup WD is full (because of the previous backup which I can’t make visible). So how to delete this old backup (which I used to restore my first WD) properly ? I do not see it in either WEB Interface.
Thanks in advance,
Vladimir.
