With SPS 2003, you can build a highly available shared services deployment
within a single data center. You can also perform log shipping (whitepaper

hot backup site  hosted in a separate data center. That sounds like it's what
the customer is after.

The one thing that is not supported (and thus no one has built it) is geo
replication of data across disparate data centers. You can't have two active
farms pushing data between each other.

Using a product like DoubleTake can let you create geo-cluster or
automatic replication.


It works much better than the SQL built-in log shipping and allows
automated failover on geographically dispersed site.

Who provides the first line of support for the overall integrated solution
(Double-Take, Windows Server 2003, SQL Server 2000 and SharePoint 2003)?

My client uses Dell servers ...I guess Dell would be the logical choice?

Does Microsoft PSS support Double-Take? ...I'm guessing they don't.

DoubleTake operates at the OS level and it has been certified for
Windows Server 2003. I don't think PSS will support it but overall I
don't see any problems with Sharepoint
