Is it safe to check a backpack on a plane?

Isn't there a risk involved in checking a backpack on a plane? Aren't there stories of luggage getting lost or even stolen? How can we ensure that our belongings are SAFE during the journey? Are there any precautions we can take to minimize the chances of our backpacks being mishandled or damaged? And what about the contents inside the backpack - are there any restrictions on what we can pack? Can we trust the airline to handle our belongings with care? It's a legitimate concern, especially for travelers who value their belongings and want to ensure their safety during a flight.
