Microsoft squashes Exchange Server bug

A shot at beating backup borkage

Redmond has issued a patch for Microsoft Exchange Server 2013 to cure a bug that borked its backups.

The sleep-wrecking (for sys admins, anyhow) bug tipped backups into a bucket, whether using Windows Server Backup or third party products, according to this Knowledge Base article.

The backup crashes would report problems with “The Microsoft Exchange Replication service VSS Writer”, something that Microsoft said happened because “an internal structure is not initialised properly in Exchange 2013.

As the update explanation states: “Cumulative Update 3 includes a fix for an issue which may randomly prevent a backup dataset taken from Exchange Server 2013 from restoring correctly. Customers who rely on Backup and Recovery in their day-to-day operations are encouraged to deploy Cumulative Update 3 and initiate backups of their data to ensure that data contained in backups may be restored correctly.”

In addition to the backup fix – the most important bit – Redmond says it's tweaked the Exchange admin console and the audit log, and removed the requirement that Windows 8.1/IE11 for the use of OWA Light.
