Harmless 'Stat backup' error logs after upgrading to ESXi 8.0u3

Products

• VMware vSphere ESXi

Issue/Introduction

After upgrading to VMware ESXi 8.0u3, the following error logs appear periodically (every hour) in the syslog:

configStoreBackup[569181]: Stat backup /var/lib/vmware/configstore/backup/current-store-1: rc = 0, errno = 0
configStoreBackup[569181]: Stat backup /var/lib/vmware/configstore/backup/datafile-store: rc = 0, errno = 2

Environment

ESXi

Cause

These messages are generated during the hourly backup process of the ConfigStore.

The rc = 0, errno = 0 indicates a successful check for the current store.
The rc = 0, errno = 2 (ENOENT - No such file or directory) occurs when the backup script checks for specific data files that may not exist in certain configurations.
This behavior is considered expected and occurs even in healthy, standard ESXi environments.

Resolution

No action is required. These logs are harmless and do not indicate a functional issue with the ESXi host or the ConfigStore backup process. They can be safely ignored.
