 Script that adds another route to internet. Add table "admin" to /etc/iproute2/rt_tables once before running the script the first time. Here, 10.0.0.138 is the router, eth0 is the network device that connects to the secondary route.
 ----------------------------------------
 
 #!/bin/bash
 #Add table "admin" to /etc/iproute2/rt_tables
 myotherdevice=eth0
 myothernetwork=10.0.0
 myothergateway=10.0.0.138
 myotherip=$(ifconfig | grep $myothernetwork | cut -d: -f2 | cut -f1 -d' ')
 ip route add ${myothernetwork}.0/24 dev $myotherdevice src $myotherip table admin
 ip route add default via $myothergateway dev $myotherdevice table admin
 ip rule add from ${myotherip}/32 table admin
 ip rule add to ${myotherip}/32 table admin
 ip route flush cache

 Script that downloads a directory using rsync, with resume.
 ----------------------------------------
 
 #!/bin/bash

 do
     rsync -avrvv --size-only --partial --progress username@host:/source_dir destination_dir
     if [ "$?" = "0" ] ; then
         echo "Rsync completed normally."
         exit

 Same, but binds the connection to the other interface/route (10.0.0.2 is the assigned ip).
 ----------------------------------------
 
 #!/bin/bash
 
 while [ 1 ]
 do
     rsync --address=10.0.0.2 -avrvv --size-only --partial --progress -e 'ssh -oBindAddress=10.0.0.2' username@host:/source_dir destination_dir
     if [ "$?" = "0" ] ; then
         echo "Rsync completed normally."
         exit
     else
         echo "Rsync failed. Retrying in 3 minutes."
         sleep 180
     fi
