Microsoft Issues Exchange Server 2013 Update for Buggy Backups
In Exchange Server 2013 Cumulative Update 3, Microsoft alleviates, among other bug fixes, issues that prevent the successful restoration of Exchange data from backups.Organizations that are leery of their Exchange backups can breathe a sigh of relief. Microsoft released Exchange Server 2013 Cumulative Update 3 on Nov. 25, which addresses a problem in the way the email platform handles data restores. In an Exchange Team Blog post, the group drew attention to an important fix aimed at "customers who rely upon Backup and Recovery mechanisms to protect Exchange data." In short, restoring Exchange 2013 (Standard and Enterprise) backup data was a hit-or-miss affair prior to the patch. "Cumulative Update 3 includes a fix for an issue which may randomly prevent a backup dataset taken from Exchange Server 2013 from restoring correctly," informed the company. The issue affected both Windows Server Backup and third-party products, according to a knowledge base article (KB2888315) describing the bug. The update should provide a remedy for IT administrators that have encountered the following error messages:
"The Microsoft Exchange Replication service VSS Writer instance 'GUID' failed with error code 0x80070015 when preparing for a backup of database 'DatabaseName'.
"The Microsoft Exchange Replication service VSS Writer could not obtain the log file signature for database 'DatabaseName'. The msexchangerepl service may need to be restarted and the backup retried after all copies reach a stable mounted or healthy state."
- Usability improvements when adding members to new and existing groups in the Exchange Administration Console
- Online RMS available for use by non-cloud based Exchange deployments
- Improved admin audit log experience
- Windows 8.1/IE11 no longer require the use of OWA Light
