  That depends how fast the network you're running is, and how much
data you've got to worry about, and maybe other things.

  Gigabit Ethernet can stream 125,000,000 8-bit quantities per second.
 Framing and protocol overhead rob significantly from that.  Let's
assume 75% efficiency, just to have a number.  That's 93 megabytes per
second, or 337 gigabytes in one hour.  If you're only backing up a
terabyte, that might be just fine.  If you're backing up a petabyte,
not so much.
