<#
  .SYNOPSIS
  Creates ad-hoc and scheduled backup of openWB wallbox.
  .DESCRIPTION
    This script will create a backup of the openWB wallbox and store the backup in a folder while keeping older versions. The script can also register a scheduled task to automate the backup creation. 
    Starting the script without any parameters will 1) ask for the IP of the openWB, 2) check if a scheduled task already exists. A new task will be registered if needed and an immediate backup will be created. Script will not perform any action if backup job already exists. 
    Start script with -RunOnce parameter to perform an immediate backup without creating the scheduled task.
  .PARAMETER LocalBackupFolder
  Specifies local path to store backups. Defaults to script location
  .PARAMETER OpenWBIP
  IP of openWB, required parameter.
  .PARAMETER VerboseLogFileName
  Logfile for Verbose output, defaults to VerboseOutput.Log if not specified
  .PARAMETER AppendToLogfile
  Appends to existing verbose log file, defaults to override.
  .PARAMETER RunOnce
  Execute backup directly, skip creation of scheduled task.
    .EXAMPLE
  PS> .\Get-OpenWBBackup.ps1
  Checks for scheduled task, creates one if it doesn't exist already. openWB backup will be executed every 4 weeks, Monday at 09:00 local time. Reruns if time is missed. After creating the task an immediate backup is created. 
  Skips all actions if a scheduled task already exists.
  .EXAMPLE
  PS> .\Get-OpenWBBackup.ps1 -OpenWBIP 192.168.178.200 -RunOnce
  Performs an immediate backup of OpenWB 192.168.178.200 and skips creation of scheduled task.
