Except for ‘TMS’ all are configured to store backups on a Network Directory:

The backup jobs create several *.tar files; here just for the ‘UCM’ component:

CISCO is provides the Platform Administrative Web Services as interface to communicate with their system.

The API reference explores that the backup status is available through the ‘Maintenance Service’.
A SOAP envelope* needs to be formulated to get the information.

<?xml version='1.0' encoding='UTF-8'?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:ser="server_url">
    <soap:Header/>
    <soap:Body>
        <ser:getBackupProgress xmlns:ns="server_url"/>
    </soap:Body>
</soap:Envelope>

The lines above are only a part of required code. Missing is the correct web addressing.

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://services.api.platform.vos.cisco.com">
   <soapenv:Header xmlns:wsa="http://www.w3.org/2005/08/addressing">
      <wsa:Action>urn:getAPIVersion</wsa:Action>
      <wsa:ReplyTo>
         <wsa:Address>http://www.w3.org/2005/08/addressing/anonymous</wsa:Address>
      </wsa:ReplyTo>
      <wsa:MessageID>uuid:26634481-3273-4a70-b537-ab4b874e4d6b</wsa:MessageID>    
      <wsa:To/>  
   </soapenv:Header>
   <soapenv:Body>
      <ser:getAPIVersion/>
   </soapenv:Body>
</soapenv:Envelope>

The final envelope looks like this:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:ser="http://services.api.platform.vos.cisco.com">  
  <soap:Header xmlns:wsa="http://www.w3.org/2005/08/addressing">  
    <wsa:Action>urn:getBackupProgress</wsa:Action>  
    <wsa:ReplyTo>  
      <wsa:Address>http://www.w3.org/2005/08/addressing/anonymous</wsa:Address>  
    </wsa:ReplyTo>  
    <wsa:MessageID>uuid:dc75e529-34fb-4009-b594-d801ec86f39e</wsa:MessageID>  
  </soap:Header>  
  <soap:Body>  
    <ser:getBackupProgress/>  
  </soap:Body>  
</soap:Envelope>

PowerShell offers the Invoke-Webrequest cmdlet to pass SOAP envelopes to a Web-Service.
Important here is to formulate the correct header.  The following works:

"Authorization" = "Basic "+[System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($ciscoUser+":"+$ciscoPwd))

The complete code to get the backup status :

$serverURL = 'https://srvauc521/platform-services/services/MaintenanceService?wsdl'

$soapRequest = [xml]@"
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:ser="http://services.api.platform.vos.cisco.com">  
  <soap:Header xmlns:wsa="http://www.w3.org/2005/08/addressing">  
    <wsa:Action>urn:getBackupProgress</wsa:Action>  
    <wsa:ReplyTo>  
      <wsa:Address>http://www.w3.org/2005/08/addressing/anonymous</wsa:Address>  
    </wsa:ReplyTo>  
    <wsa:MessageID>uuid:dc75e529-34fb-4009-b594-d801ec86f39e</wsa:MessageID>  
  </soap:Header>  
  <soap:Body>  
    <ser:getBackupProgress/>  
  </soap:Body>  
</soap:Envelope>  
"@

$header = @{"Authorization" = "Basic "+[System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($ciscoUser+":"+$ciscoPwd))}

 
   $result = Invoke-WebRequest -Uri $serverURL -Headers $header -Method:Post -Body $soapRequest -ContentType "application/soap+xml" -usebasicparsing
  
  [xml]$SOAP = $result.Content 
  $xmlResult = $SOAP.Envelope.Body.getBackupProgressResponse.return.backupProgressResult.componentList

The content of $xmlResult variable is a plain text array which can be easily further processed

Worth to note is that the backup status overall can be queried separately via:

$backupOverallStatus = $SOAP.Envelope.Body.getBackupProgressResponse.return.backupProgressResult.status
if ($backupOverallStatus -notmatch 'SUCCESS') {
  	$foo = ‘send success mail for instance …’
}
