I think the network card speed is not a problem here, since it's not used 
for actual data transfer. Just a coincidence you happen to reach 100M/8 
rate.

My first guess is that database & filesystem performance could be the 
bottleneck. Do you have the catalog files on the same physical disk, that 
you are backing up? And where do you write the data, to the same physical 
disk, maybe? All that could cause a lot of disk seek activity. Maybe adding 
memory might speed it up, since the OS could buffer more data. And if you 
can somehow enable disk write cache too... but it would involve problems if 
the system ever happens to crash.
