VMware vSphere • Re: An error occurred while saving the snapshot: Invalid change tracker error code

I'm encountering this error on a single VM. I've upgraded and reinstalled VMware Tools


Environment:

• VMware ESXi, 7.0.3, 22348816
  Windows Server 2022 Datacenter
  SQL Server 2022
  Veeam B&R 12.0.0.1420 P20230412

Problem:
Manual VMware Snapshot fails, Veeam backup (Incremental and Active Full) fails, both with the same error message:

3/21/2024 5:49:47 PM ::Processing VM_NAME Error: An error occurred while saving the snapshot: Invalid change tracker error code. (An error occurred while saving the snapshot: Invalid change tracker error code., An error occurred while taking a snapshot: Invalid change tracker error code.)


Investigation:

• Windows Event Logs seem clean
  VSS Writers show no errors
  Can manually create new Shadow Copy

Troubleshooting Steps:

• vMotion to another host did not resolve
  Upgrade of VMware Tools did not resolve
  Uninstall/Install of VMware Tools with Reboot resulted in a new error message in Veeam: VSSControl Failed to prepare guest for freeze, wait timeout 900 sec
  Same Invalid change tracker error in vCenter when trying to manually create snapshot

Still no resolution at the time of this post.
