Has anyone come up with a good DR plan for EPDM?

We are in the middle of a new implementation project and the DR plan from the consultants leaves a lot to be desired.

1) your porduction data center goes down for whatever reason

2) build brand new servers in your DR data center with the same exact server names and IP addresses (archive and database servers)

3) from tape backups of the entire (dead) servers, restore to the new DR servers.

4) Presto magic, production is live in your DR data center.

Surely someone has a better DR solution than that?

If I better understood the need for the DR servers to have the same name and IP addresses as the production servers....

Thanks for any feedback.
