Problem: Veeam Pre-Freeze / Post-Thaw .sh Scripts Fail on Linux Guest VMs (e.g. Ubuntu) with "Failed to execute script in guest OS" although the scripts run fine. I use Hyper-V but that should not matter. Failing scripts are configured to "Require successful script execution" under "Application-Aware Processing Options" under "Guest Processing" in the Veeam backup job. My Solution: Some commands executed inside the scripts seem to return error output which is passed back to Veeam through the script and confuse Veeam so it reports that the script was not successful. So we must redirect error output from such commands to 2>/dev/null or some file, otherwise error status is passed back to this script and Veeam reports a failure.
