Create a scheduled task that will run a PowerShell script at 1:00 AM, in this example a script that will make a backup of a MongoDB Database

createSystemScheduledTask.ps1

$scriptToExecutePath = "C:\Path\To\dump-script.ps1";
$taskName = "MongoDB Backup - <databaseName>"
$taskDescription = "Make a dump of <databaseName> database"

$action = New-ScheduledTaskAction `
  -Execute 'C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe' `
  -Argument "-NoProfile -NoLogo -NonInteractive -ExecutionPolicy Bypass -File $scriptToExecutePath"
  
$trigger = New-ScheduledTaskTrigger -Daily -At 1am

Register-ScheduledTask `
  -TaskName $taskName `
  -Action $action `
  -Trigger $trigger `

# Start-ScheduledTask -TaskName 'MongoDB Backup - <databaseName>'
