I am tasked with retrieving information about a given Azure Backup Vault, and whether the backup(s) are successful or unsuccessful. If successful, I must record how much data has been backed up through a PowerShell function.

I was able to find a command that gave me the backup date(s) and the progress of each backup; however, I was not able to find a command or a set of commands that told me how much data has been backed up for each.

This is the function I have so far, it only gives me the list of backup jobs:

Function Get-AzBackupInfo
{
  $nameList = (Get-AzRecoveryServicesVault).Name
  $resourceGroupList = (Get-AzRecoveryServicesVault).ResourceGroupName
  $hostname = hostname

  for ($i = 0; $i -lt $nameList.Length; $i++)
  {
    if ($resourceGroupList[$i] -match $hostname)
    {
     $var = Get-AzRecoveryServicesVault -Name $nameList[$i] -ResourceGroupName $resourceGroupList[$i]
     $jobList = Get-AzRecoveryServicesBackupJob -VaultId $var.ID

    }
  }
   $jobList
}

Are there any modifications / additions I can make to this function that will give me the amounts of data (in GB) that have been backed up?

How to Retrieve Amount of Storage Backed up (in GB) by Azure?

You can use the below PowerShell script which fetches the usage of Azure recovery vault.

Script:

$subscriptionId = "xxxx"
$resourceGroupName = "xx"
$vaultName = "vxxxd"
$apiVersion = "2024-10-01"


$uri = "https://management.azure/subscriptions/$subscriptionId/resourceGroups/$resourceGroupName/providers/Microsoft.RecoveryServices/vaults/$vaultName/usages?api-version=$apiVersion"

$accessToken = (Get-AzAccessToken -ResourceUrl "https://management.azure").Token

# Call the API
$response = Invoke-RestMethod -Uri $uri -Method Get -Headers @{ Authorization = "Bearer $accessToken" }

# Convert Byte values to GB
$convertedResponse = $response.value | ForEach-Object {
    if ($_.unit -eq "Bytes") {
        $_.currentValue = "{0:N2} GB" -f ($_.currentValue / 1GB)
    }
    $_
}

# Display the results
$convertedResponse | Format-Table -AutoSize

The above script retrieves the usage details of an Azure Recovery Services vault by calling the Azure REST API. It authenticates using Get-AzAccessToken, fetches the usage details via Invoke-RestMethod, and converts byte values to GB for readability before displaying them in a table.
