FBI is NSA's front man for domestic programs. see DITU and how PRISM, while an NSA program, is coordinated through FBI. FBI does provide blanket surveillance, although they must launder information through parallel construction before the surveillance becomes legally actionable.
NSA collects nearly all internet traffic in the USA with its intercept rooms at the network control centers that big telecoms have on the internet backbone. They gather almost everything, including content, not just metadata. The announced capacity of the Bluffton, Utah data center is several orders of magnitude more than is needed to store metadata alone.
to be clear, they inspect nearly everything in-line with "Deep Packet Inspection" and "semantic analysis" and similar techniques, e.g. Narus Insight, at the edges rather than centrally. there is an order of magnitude less capacity for NSANet uplink than what is monitored through taps. they could not pull a mirror of all traffic if they wanted to! then, the selected stuff is collected and stored forever*. the Utah massive data repository is not full take buffer, but rather persistence for selected or collected information. (full take on backbones a technical challenge, and not everywhere.)
... With the FBI, as far as I know, you have to be targeted (except for the IMSI catcher type stuff, which are indiscriminate but not an nationwide/international dragnet). The AP story about the FBI surveillance planes is quite interesting, although fits with recent info and long term trends.
as discussed elsewhere, you can get "selected" for various activities, which is auto-targeting, in a sense... best regards, * for some definition of "forever".
