Redundant Internet connection

We have a company that has 2 sites that have an Ethernet connection between them that is independent of the Internet connection. Each site has a separate internet connection and we want to provide redundancy that if one sites internet failed it will automatically go across the Ethernet connection and use the other sites internet instead of their own. They have draytek 2830 router at each site They are both on the same LAN subnet

 Is this possible to setup?

Do not know how your client gets internet, through router gateway or proxy server ?

Normally if you have two proxy servers at two locations having ethernet (WAN) connectivity, then you can write .dat or .pac file and distribute it through DNS or DHCP.
In 'pac \ .dat file you can write code so that clients will get another proxy server if one got failed at there location.

In that case it is not possible.
because you cannot chnage IP configuration across sites.
