So I want to back up my tails USB since it has my bitcoins and such on it, but there's ALLEGEDLY incriminating info in the persistence. Will it be safe to host a backup Image of the tails USB drive on google drive/dropbox, even if the ALLEGED image was taken by LE, would they be able to get info off of it?
Just back it up to a usb and burry the usb drive somewhere. You can put the usb into some plastic bags and then a container (something to keep the water out) --- Very simple.
