Not very long, they get eaten! 😉
But the real answer to that is, it depends on what it is. Smoked salami, weeks for sure. Jerky, possibly months. Smoked salmon, I suggest less than a week.
And as others have said, there is no rescue for freezer-burned meat. Mind you, I have had this happen with a larger cut, and been able to trim off the bad parts and still salvage most or some of the meat. But a badly freezer-burned piece, especially something thin, is dog food or compost.
