To Save one's bacon
To Save one's bacon : Phrases
A situation that has been rescued.
This has little to do with the bacon that was brought home above: rather the word here could derive from Baec which is Old Dutch and Anglo-Saxon for back. However, like many sayings, there are other suggestions as to the origin. The most likely of these is that, in the early 17th century bacon was thieves slang for escape.
