The provided script is using the Veeam Backup & Replication PowerShell module to retrieve a list of VMs for each backup job on the Veeam server. Here's a breakdown of the script:

1. The script starts by importing the "Veeam.Backup.Powershell" module, which provides cmdlets for interacting with Veeam Backup & Replication.

2. It then retrieves a list of all backup jobs using the `Get-VBRJob` cmdlet and assigns it to the `$backupJobs` variable.

3. The script enters a `foreach` loop to iterate through each backup job in the `$backupJobs` variable.

4. For each job, it writes the job name to a text file located at "C:\temp\veeamOutput.txt" using the `echo` (or `Write-Output`) cmdlet.

5. Next, it writes a section header "VMs Covered:" to the same text file.

6. The script retrieves the list of VMs covered by the current job using the `$job.GetObjectsInJob()` method and assigns it to the `$vms` variable.

7. Another `foreach` loop is used to iterate through each VM in the `$vms` variable.

8. For each VM, it writes the VM's name to the text file.

9. After iterating through all the VMs, it writes a line of dashes as a separator to the text file.

The script repeats this process for each backup job, providing a list of VMs covered by each job in the "C:\temp\veeamOutput.txt" file.

Overall, the script allows you to gather information about the VMs associated with each backup job in Veeam Backup & Replication and store it in a text file for further analysis or reporting.

<code powershell>
Import-Module Veeam.Backup.Powershell

# Get a list of all backup jobs
$backupJobs = Get-VBRJob

# Iterate through each backup job
foreach ($job in $backupJobs) {
    echo "Job Name: $($job.Name)" >> "C:\temp\veeamOutput.txt"
    echo "VMs Covered:" >> "C:\temp\veeamOutput.txt"

    # Get the list of VMs covered by the job
    $vms = $job.GetObjectsInJob()

    # Iterate through each VM and display its name
    foreach ($vm in $vms) {
        echo $vm.Name >> "C:\temp\veeamOutput.txt"
    }

    echo "----------------------" >> "C:\temp\veeamOutput.txt"
}
