Replication

[Kundan]

Replication of DB has been totally eliminated in Access 2013. Is there any substitute for it?

No. It was scrapped with A2007 when the ACCDB format was released.
If needed, you will have to write your own code to manage that functionality.

Alternatively use SQL Server or similar as the back end.

If your database is important enough that it requires replication then it aught to have a server backend. I believe that was Microsoft's thinking when they dropped Replication from Access.
