It lasts quite a while. If you can store in the fridge as air-tight as possible, you can expect at least a couple weeks, probably more. Freezing, as you suggest, means 'as long as anything else'. I usually slice what I think I'll use in a week or so, then section the rest of the belly and freeze each section separately. As needed, I'll partially thaw a section in the fridge or on the counter then slice while it is still somewhat frozen (easiest that way), then wrap and fridge.
