What is Backup? Is that a custom class?

There are a huge number of possible reasons why a backup may fail.
Try this: Backing up an SQL Database in C#[^]

I'm getting error as "backup failed for server" at line

ServerConnection con = new ServerConnection(@"xxxxx\SQLEXPRESS");
What to do now?

Look at the error and see if there is any inner error.
Did you follow all the steps in the tip.
