Exchange 2013 Cumulative Update 3

Today on viewing the KB article for Backup restore failure found they have launched Exchange 2013 Cumulative Update 3 which is the know cause for backup restoration failure...

This is a known issue in versions of Exchange Server 2013 that are earlier than Cumulative Update 3. This issue occurs because the LOG_SIGNATURE_ID and LOG_SIGNATURE_TIMESTAMP elements in the Backup Components Document have a value of 0 in the backup stage. However, the Exchange VSS writer prohibits restoring data in this state.

But the good news is that they have still not launched Exchange 2013 Cumulative Update 3. Microsoft is so fast in publishing the KB before they launch the product in public.. :)
