If the nics support auto-mdi-x will it get full gbit on a strait cable?

yes - in theory (if the cable has 4 pairs of wires)
never tried this myself, but read about this very often....

at least you cannot use an "ordinary" crossover cable, because gigabit needs
all 4 pairs of wires being crossed
btw - many gbit nic`s do auto-crossover, so you probably donĀ“t even need a
crossover cable but just an ordinary gbit cable....

If the nics support auto-mdi-x will it get full gbit on a strait cable?

I'd have to agree. We're syncing up a respositiory over about 20 servers
that totals 200G in size right now (30D worth of increments included),
and it's done in <10 hours, over a 1.5MBit internet line.

Agreed, but since rsync apparently isn't any faster it seems like the
issue is with something other than rdiff-backup.

BTW, are you sure you're getting a gigabit connection? I don't think you
can actually do that with a crossover cable...
