You probably want to look at the "metric" option when setting your
routing table.  I believe you should have two "default" routes
(0.0.0.0), and the "backup" interface should have a higher metric value
than the normal interface.  It might look something like this, then
again it might not:

Destination     Gateway         Genmask         Flags    Metric   Ref   
Use  Iface
default         10.0.0.1        0.0.0.0           U        0      
0      0    eth0
default         192.168.0.1     0.0.0.0           U        1      
0      0    eth1
