VMware has released a long-awaited patch for the ESXi 6.0 CBT bug, which affects all customers who upgraded to or installed ESXi 6.0. The bug, described in KB2114076, causes backups to fail when Change Block Tracking (CBT) is enabled. The symptoms of this issue include longer running backups, and the only known workaround has been to disable CBT.

The patch, ESXi600-201505401-BG, can be downloaded from VMware’s website or applied using VMware Update Manager. It is important to note that a reboot is required after applying the patch.

If you have disabled CBT for all or some of your VMs, make sure to re-enable it after applying the patch. This will ensure that backups can be taken successfully and that your virtual machines are properly protected.

The release of this patch is a significant development for ESXi 6.0 users who have been impacted by this issue. The ability to take successful backups is critical for maintaining the integrity and availability of virtualized infrastructure, and the fix provided by VMware will help ensure that these environments remain stable and reliable.

It is important to note that the patch only applies to ESXi 6.0, and does not affect other versions of ESXi. If you are running an older version of ESXi, you may need to consider upgrading to ESXi 6.0 in order to take advantage of this fix.

In conclusion, the release of the ESXi 6.0 CBT bug patch is a welcome development for users of this virtualization platform. The ability to take successful backups is crucial for maintaining the integrity and availability of virtualized infrastructure, and the fix provided by VMware will help ensure that these environments remain stable and reliable. If you have been affected by this issue, we encourage you to apply the patch as soon as possible to avoid any further disruptions or complications.
