I have written a backup script in powershell. I authorised it with Unblock-File, so it can be run without having to interact.

I used gpedit to add it to the powershell scripts to be run on shutdown.

While the script works well wenn executed directly it just fails to run on shutdown.

I disabled fast boot and hibernation as described in the second answer to this question but nothing changes.

How can I find out

  • whether my script fails
  • or the script is not called at all
  • and wtf happens during shutdown

Addendum: more information

  • The script opens a network connection to a NAS and defines a network drive
  • it then copies local data to a newly created folder on that network drive using date and time as name for the folder
  • upon completion of the copy process, the network drive is disconnected.
  • I considered "at shutdown" as a good analogon for "some work done". I think that when shutting down the computer wilfully, some progress is very likely to have happened.
  • I don't know if it is the best choice to do it at shutdown, but it is the best choice I know. Perhaps it could be done on every change of a file automagically?
  • I used gpedit.msc to install the script and I went to Computerkonfiguration->Windows-Settings->Scripts->Shutdown. There I added the script in the dedicated "PowerShell-Scripts"-Tab. Ichanged the sequence settings so that the PowerShell-scripts are executed first.
  • The script has a local path, C:\Backupsoftware\Smart_Backup_Create_folders_by_Date_MK.ps1
  • The Data which shall be copied is on the Desktop and in the documents folder of a certain user account.

More Details I followed flolilolilo's suggestions and added a line at the beginning of my script, which basically does some printf-debug (or is it Write-Output-Debug?). The place where I found the text output file was 

C:\Windows\System32\GroupPolicy\Machine\Scripts\Shutdown

So the script is apparently called but does nothing other than putting out the debug information. Can I redirect errors and warnings into a text file?

Ah, and how do I mount the NAS?

New-PSDrive -Name "backup" -PSProvider Filesystem -Root "\\169.254.100.100\share"

Third Addendum

Here comes the current code.

#System Variable for backup Procedure

# $date = Get-Date -Format d.MMMM.yyyy
$date = Get-Date -Format yyyy.MM.dd.HH.mm.ss

Write-Output "This script was called at %(Get-Date)" | Out-File .\test.txt
 New-PSDrive -Name "backup" -PSProvider Filesystem -Root "\\169.254.100.100\Krautlight_aktiv"

 # $source = "D:\Tally\Data\"
$destination = "backup:\$date"
 # $path = test-Path $destination

$homeprefix= "C:\Users\MyUser\"

$directories = @{ }
$directories.add($homeprefix+"Documents\eagle", "EDA\eagle")
$directories.add($homeprefix+"Documents\KL\Eaglelibraries", "EDA\eigeneLibraries")
$directories.add($homeprefix+"Desktop\Flansch", "CAD\Flansch")
$directories.add($homeprefix+"Desktop\BoCubeDateien", "CAD\Bopla")
try{
  mkdir $destination
  ; write-outpot "mkdir passsed"  | out-file .\test.txt -append;
  }
catch
    { write-output "mkdir  failed" | out-file .\test.txt -append }
ForEach($source in $directories.KEYS.GetEnumerator()) 
{
        cd backup:\          
        $destpath=$destination+'\'+$directories.Get_Item($source)
       Copy-Item  -Path $source -Destination $destpath -Recurse 
        cd c:\
}
 Remove-PSDrive "Backup"

My current investigations show a working output of debug messages to the test.txt file. And the mkdir fails.
