Hello and welcome everyone

the question for 100points.

My backup server is connected to 4 different networks. Each of them have a separate gateway. I would like to use this four gateways to download backups at the same time.

Let say that this is my network settings:

eth0 - 192.168.1.5 gw 192.168.1.1

eth1 - 192.168.2.5 gw 192.168.2.1

eth2 - 192.168.3.5 gw 192.168.3.1

eth3 - 192.168.4.5 gw 192.168.4.1


How can I setup something like this...

backupscript-1.sh will use eth0

backupscript-2.sh will use eth1

backupscript-3.sh will use eth2

backupscript-4.sh will use eth3


Is it possible on one machine ? Right now I have a network bottle neck and I cant download 50Gb of data by night...

Thanks for help...

I presume the backupscripts are downloading from hosts somewhere. What IPs do these hosts have? If they are public, you might have issues. You could do something like adding a /0 or /8 network for the public IP of each host to each interface... it sounds messy doing it like that though.

If, however, your networks are as you have described above, and are all private, what you describe will work fine. the backupscript connecting to the host on the 192.168.1.x network will automatically use eth0, 192.168.2.x will automatically be routed through eth1 and so on.

yes, backup server is behind the firewall.

its making backup from local LAN and public servers. Mostly huge oracle tar balls.

Thats why I need more network connections...

It's going to be difficult since they're public hosts.
You could specify the connection if it was the hosts being backed up that initiated the connection rather than the backup server.
Another possbility is increasing your bandwidth...
