Like all systems built on top of SQL Server SharePoint 2010 needs to have a plan for availability. There are many methods for configuring high availability, one of which is database mirroring. Other options, such as clustering will be discussed separately.
Database mirroring is a SQL Server technology used for providing database redundancy. It is configured on a database level, not the server level. With this method any transaction on the principal server are sent to
the mirror server/database as soon as the transaction log buffer is written to disk on the principal server/database. The downtime in failover is generally measured in seconds, not minutes.
SharePoint supports both mirroring and clustering for failover. While both do a great job in the case of a failure the question often comes up as to what databases support each option. Many service applications create their own databases, such as the Search Service creating an administration, crawl and property database. The vast majority of the databases support mirroring with the exception of only two at the time of writing. Keep in mind this is information taken from MSDN and applied to SQL Server 2008 R2 and SharePoint 2010. This information could change for SQL Server 2012 as the back end or with future versions of SharePoint.
The only two databases that do not support mirroring are:
User Profile Service: Synchronization database
Web Analytics Service: Staging database

About Pratik Vyas

Hi Readers, Welcome to Pratik’s SharePoint Blog. First of all Thank you very much for taking interest and spending time to tour my Blog I am in the ocean of SharePoint since January 2008 (almost 4 years), and still I feel I have to go more deep. I am working with a well known MNC as a SharePoint Consultant. Here I used consultant because I do a little development and customization with administration. I am very much interested in Microsoft products. I have started blogging since 2008 but I can say in real manner I have started it in 2011 (as I have posted only 4-5 blogs from 2008 to 2011 J) I believe there isn’t anything impossible in SharePoint, the only thing is sometimes we have to think something off track. I have posted couple of blogs which was discovered by going some off track, we can simply say it TRICKS. Feel free to reach me in case of any issues or queries I will be more than happy to help you. Good bye and Happy Reading, Cheers !!
