*Usually*, 1Gb/s networks are sufficient.

You did not state what your services you backend is going to be supporting
(especially if it will be a "shared" system).  For a BE, how many networked
tuners, how many active frontends?  A HD stream usually fits in (less than)
about 20Mb/s, so you could be recording from 10 simultaneous network tuners,
and playing back concurrently to 10 frontends and still be at no more than 40%
network utilization with a gigabit card on a dedicated BE (and likely much less,
since most HD content is not 20Mb/s).  At those rates, your disk subsystem
would probably need more attention than your network.

As with all else, your mileage will vary.
