Let me clarify @oldturkey03's answer if I may.
The brake booster is basically what gives you power brakes. Although we take it for granted nowadays, cars did not always come with power brakes. Those that didn't required significant effort in pushing the brake pedal to get the car to stop. The addition of a brake booster uses a vacuum motor to amplify your foot press and make it easier to push the pedal hard enough to stop the car.
So now we have power brakes, and almost all of them work off of the vacuum generated by the air flowing inside the intake manifold. However, some newer vehicles like yours do not generate enough vacuum to run a brake booster. When that's the case, rather than redesign the brake booster to run off some other form of power, they add a vacuum pump to create enough vacuum for the old school style of brake booster.
So there's where you get the two separate things. Other cars only have a brake booster, but yours has a vacuum pump and a brake booster, and both are required for you to have power brakes.

@summerwiles I can tell you that they are not the same things. Brake booster and vacuum pump are two separate things. The vacuum pump removes air from the brake booster. The particular model 2013 BMW 328i had issues with the vacuum pump on their new models and had reports of brake failures.
Looks like the part number for the vacuum pump is 11667622380 and looks like this Example only not an endorsement
BMW calls the brake booster the brake servo unit. The part number should be 34336851099 unless your vehicle has M sport brakes, then the part number is 34336851098
Parts are widely available from many sellers, even places like Autozone etc. Always verify the numbers and fit with the seller.

could you share more info about brake failures i didn't hear about it before
真空泵了刹车助力泵，这两个是单独分开的东西不是一个东西真空泵是装在发动机上的刹车助力泵是刹车分泵还是刹车大力鼓上的总泵
English translation:
The vacuum pump and the brake booster pump are two separate things. The vacuum pump is installed on the engine. The brake booster pump is the brake slave cylinder or the master cylinder on the brake drum.
