I am looking for a DR clustering solution not HA one. I believe SCR is the
way to go. My question is, can you setup an SCR cluster against a single
exchange server (one with no other clustering involved like CCR, LCR, SCC).
The end product woud be a single exchange 2007 server in our head office and
a single SCR server for DR failover in our fail over office.

Thanks

Yes.

SCR can be setup in different source and target configurations -
clustered/non-clustered source and clustered/non-clustered targets. You need
to be aware of the different recovery options available for a configuration.

For s standalone source and a standalone target, the options are a) Database
Portability b) Setup /RecoverServer (on a server without Exchange
installed... ).

Thanks for the reply.

Can an SCR server be implmented against an existing Exchange 2007 server
(i.e. not during the initial install phase)? Also, is SCR supported with
Exchange 2003 STD Edition?

Yes. SCR does not use clustering by itself. You can add one or more SCR
replicas for a standalone/SCC/CCR source at any time.

- Continuous Replication features (LCR, CCR and SCR) are available in
Exchange 2007.
- You can't use them to replicate Exchange 2003 Storage Groups. (Exchange
2003/2000 servers cannot be SCR sources. You need Exchange 2007 SP1, on the
same version of Windows OS.)

- Exchange 2007 servers can co-exist with Exchange 2003/2000 servers in the
same Exchange Organization.
