Cloud Storage Replication Is Not Backup

The options that you need to select when setting up an Azure Storage service account allow you to specify the durability and high-availability of your data, but they don't provide for data recovery to a point-in-time. In fact, it means that some of the bad things that can happen to data are more efficiently replicated to all copies. Backup is quite a separate issue.… Read more

Implementing Cluster Continuous Replication, Part 3

Cluster continuous replication (CCR) uses log shipping and failover to provide a more resilient email system with faster recovery. Once it is installed, a clustered server requires different management routines. These are done either with a GUI tool, The Failover Cluster Management Console, or the Exchange Management Shell. You can use Powershell as well for some tasks. Confused? Not for long, since Brien Posey is once more here to help. … Read more

Some Data with your Application Take-away, Sir?

Prasanna is reminded of pizza in cardboard boxes when he explores the possibilities of Synchronization Services for ADO.NET. Data applications are becoming increasingly mobile, and often disconnected, and data is often wrapped up to be consumed later. Miccrosoft's Merge Replication was their first, and most heavyweight, solution, but now comes a different tack, based on SQL Server 2008 and ADO.… Read more

Exchange 2007 Mailbox Server Clustering

The original, rather complex, Exchange clustering, 'Single Copy Cluster', protects you against a server failure but not a database failure. 'Local Continuous Replication' protects you from database failure, but not server failure. The more simple 'Clustered Continuous Replication' protects against both. If you use it with Transport Dumpster, you won't lose emails.… Read more
