Windows 2008+ incremental backups become full backups in ESXi 6.0 b3825889

vmware_tools_iconVMware is actively working to address a recently discovered issue wherein an incremental backup becomes a full backup when backing up Windows 2008 (or higher) virtual machines with VSS-based application quiesced snapshot.

This recent CBT (Changed Block Tracking) issue does not cause any data loss or data corruption.

This issue is well understood and VMware engineering is actively working on a fix.

For more details on this issue and latest status on resolution, please refer to KB article: After upgrading to ESXi 6.0 Build 3825889, incremental virtual machine backups effectively run as full backups when application consistent quiescing is enabled (2145895)

How to Hyperlink KB articles

There are many, many, blogs, forums, videos channels out there that cover various VMware topics, and we commonly see our KB articles being linked from those sites.

We wanted to help those doing this with a couple of quick tips that will make your links easier to read and more resilient to potential changes in our CMS in the future.

When you open one of our KB articles and look at your URL bar, you’ll see a long, and parameterized URL. For example:

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1006427

As you can see, this URL includes unnecessary parameters for sharing and just looks long and ugly. Here’s a much cleaner format to use:

https://kb.vmware.com/kb/1006427

The beginning part is always the same, just substitute the actual KB number you wish to reference at the end.  Also note that we are now using https rather than the older and less secure http protocol.

Hope this helps those of you sharing our content; you have our thanks!

Knowledgebase improvements

Main objectives of the upgrade were to:

  • Upgrade the Knowledgebase application software/hardware
  • Improve stability and security of the website
  • Implement Secure Sockets Layer (SSL)
  • Implement a Captcha system into the comments area

We will continue our efforts to make the Knowledgebase system as secure and robust as our customers expect.
