I'm trying to solve a problem my company has in its data warehouse of data availability. We have dozens of transactional databases in production from which we pull data to create a cache of data that we make available to reports for both internal and external
customers.
The problem I'm trying to solve is I want all of the people using the data to still be able to access the previous version of the data (maybe data from an hour ago) while the new data is being refreshed. I have looked at a lot of ways this is possible. From the very manual, the built in solutions, or a custom drive cloning solution but I'd like to hear from the community what people think is the best way to go about this. The server version is SQL Server 2008, but we could install 2012 in time for this need.
Right now I'm leaning towards AlwaysOn Availability Groups but if there's something better I'd love to know about it.
