Challenge

When attempting to use the Veeam Backup Validator command-line tool to validate the VMs contained within a job that was using the Per-machine backup with separate metadata files (aka True Per-VM) backup chain format, the Veeam Backup Validator tool throws the error:

Cannot find last point for backup "<job-name>".

Cause

This is a known issue and will be fixed in a future release of Veeam Backup & Replication.

Solution

The following PowerShell script can be used to validate the latest restore point for all VMs within a job when it is using Per-machine backup with separate metadata files.

Notes:

Replace <job-name> with the actual backup job name.
The script must be run in an Administrative PowerShell prompt.
The script will output the reports to C:\temp\. If that folder does not exist, either create it or update the script to output to a different existing folder.

#Get backup job information based on name.
$backup = Get-VBRBackup -Name "<job-name>"
#Find child backups for job.
$child_backups = $backup.FindChildBackups()
#For each child backup found validate the latest restore point, output the results to an HTML file in C:\temp\
ForEach ($sub_child in $child_backups) {
	$id = $sub_child.Id
	$name = $sub_child.name
	Write-Output "Processing VM $name $id"
	cmd.exe /c '"C:\Program Files\Veeam\Backup and Replication\Backup\Veeam.Backup.Validator.exe" /backup:'$id' /report:"C:\temp\report_'$name'-'$(get-date -f yyyy-MM-dd_HH.mm)'.html" /format:html'
}
