Configure a Site-to-Site VPN with Backup route

[Minue]

Hello Guys
Would some one be kind enough to tell me if it's possible to configure 3 Cisco router in a Triangle with Site-to-Site VPN.Where the network behind (Router A )has to access a Server behind (Router B)and when the route between (Router A and B) goes down the (network A) uses the route via (Router C) to get to the Server behind (Router B).I hope I have made myself clear.In other words the route via Router C is just for backup.
If possible such a configuration would it be difficult to configure.I have search the web but could find any diagrams of such a network using VPN.I hope it's possible.
Best regards

Hi Dan
Can't believe you did it!!!!Thanks for all your troubles and time how can I ever repay you.
I will try it in my lab to see if I can get it to work.But as far as a real life situation,do you think it will work.As mention before,the network that I have to configure has 3 E1 lines and the 3 site want to connect with VPN's and have the redundancy to a Server behind the Router B.
Thank again
Best regards
