There has been a serious lack of original content on my blog this month, with the financial year coming to an end here in Australia, I’ve been flat out

Never fear though, Scott Schnoll over at The Microsoft Exchange Team Blog has put together a great 4 part video series on high availability in Exchange Server 2010:

In Part 1 he introduces the concept of database mobility, and the features known as database availability groups (DAGs) and mailbox database copies.

In Part 2 he demonstrates how to create a DAG and how to add mailbox servers to a DAG

In Part 3 he shows how to add a mailbox database copy

and, in Part 4 he performs a database switchover using the Exchange Management Console (EMC)
