1. I want to replicate whole data on another DC and after that both DC's
nodes should have complete Data. In which topology is it possible ?
I think NetworkTopology is best suited for such configuration, You may
want to use nodetool to generate token accordingly.
2. If I need backup, what's the command of cluster screen shot?
You can always create a snapshot/backup files and later can use them for
restoration.

3. I will use internet connection with VPN facility for traffic and in case
disconnection what will happen?
based on configuration, (e.g. hinted-handoff,consistency level,
read-repair), it should be fine.
