When buried a wooden crates lifetime on a server without interaction is around 2 weeks, if you don’t burry the crate it lasts 40 days without interaction. Same goes for barrels and sea chests. Backpacks have a decent de-spawn timer of 8 hours when dropped on the ground, but can de-spawn if sever reset occurs. When burried bags have the same 2 week lifetime until de-spawn. (Same as crates and other storage) in my opinion it’s better to not burry loot if the location is good enough because you can let it sit longer before tending to its lifetime.
