Environment

vSphere 8.x

Cause

The service account configured for VAMI backup operations is encountering an 'Invalid Credentials' error. This indicates an authentication issue with the service account, which may be due to incorrect login details or insufficient permissions, preventing successful backup configuration and execution.

Resolution

Reconfigure the VAMI backup by entering the correct service account credentials and ensuring the credentials are up-to-date and accurate. 

Verify that the service account used for VAMI backups has the required permissions on the backup target and is not locked or expired.
