Check if certain VMs are backed up - powershell

Question

I am looking for a way to check if a list of VMs has backup and what is the status.
I managed to get the status of VM backups but if the VM was not found in the $tasks I am not getting error.
I need to know if a VM is not present in the $tasks so that I know that no backup is configred for this VM.
The script so far.
Write-Host "Enter Backup Server" -ForegroundColor cyan
$h = read-host -Prompt 'Hostname'
Write-Host " "
write-host "Hostname--------Job-------------Status " -ForegroundColor Cyan
Foreach ($i in $Hostname) {
Invoke-Command -ComputerName $h -ScriptBlock {
Add-PSSnapin VeeamPSSnapin
foreach($Job in (Get-VBRJob))
{
$Session = $Job.FindLastSession()
if(!$Session){continue;}
$Tasks = $Session.GetTaskSessions()
$Tasks | ?{$_.Name -eq $using:i} | %{write-host $_.Name ":",$_.JobName,"===>"$_.Status}
}}
}
Thanks in advance!

You are nearly there, you just need to unify your exit clause so that whether a VM has backup or not, it outputs something similar. Then when you run against a list of VMs and one or two aren't backed up, they'll appear in the output in a way that makes sense.
Foreach ($i in $Hostname) {
Invoke-Command -ComputerName $h -ScriptBlock {
Add-PSSnapin VeeamPSSnapin
foreach($Job in (Get-VBRJob))
{
$Session = $Job.FindLastSession()
if(!$Session){
[pscustomObject]#{
computerName = $_.Name;
backupStatus = "Not backed up!";
jobs = $null;
}
$Tasks = $Session.GetTaskSessions()
$jobs = $Tasks | ?{ $_.Name -eq $using:i } | Select -ExpandProperty JobName
[PSCustomObject]#{
computerName = $_.Name;
backupStatus = "Backed up";
jobs = ($jobs -join ",")
}
}
}
}
With a few small tweaks, we now emit an object back if a machine doesn't have any results for $Session, but now also return a similar object for machines that do have backups enabled.
You will likely need to tweak the code to your desired results, as I don't have Veeam available I can't quite nail down what you'd like but this should get you going.
And as a perk getting PowrShell objects back is easier to work with. You can save them in a json file or csv, or run this automatically in the off hours and review the results later, all which are much easier than using Write-Host commands.

I managed to acheave my goal by comairing all backed up VMs with the VMs from my list:
Write-host "Unprotected VMs (No backup)" -ForegroundColor RED
Write-host "---------------------------" -ForegroundColor RED
invoke-command -computername $h -ScriptBlock {
Add-PSSnapin VeeamPSSnapin
$backup=Get-VBRBackupSession | Where-Object {$_.JobType -eq "Backup" -or $_.JobType -eq "Replica" -and $_.EndTime}|foreach{$_.gettasksessions() | Where-Object {$_.Status -ne "Failed"}} |foreach{$_.Name} | Sort-Object | Get-Unique
$diff=Compare-Object $using:hostname $backup| ? { $_.SideIndicator -eq "<=" } | Select -ExpandProperty InputObject
$diff
As a result I am getting only the VMs which are missing from $backup and are present only in my list $hostnames .
