	.SYNOPSIS
		This function will allow you to create a full or partial backup of your
    VCSA appliance. (vSphere 6.5 and higher)
	
	.DESCRIPTION
		Use this function to backup your VCSA to a remote location

	.EXAMPLE
        [VMware.VimAutomation.Cis.Core.Types.V1.Secret]$BackupPassword = "VMw@re123"
        $Comment = "First API Backup"
        $LocationType = "FTP"
        $location = "10.144.99.5/vcsabackup-$((Get-Date).ToString('yyyy-MM-dd-hh-mm'))"
        $LocationUser = "admin"
        [VMware.VimAutomation.Cis.Core.Types.V1.Secret]$locationPassword = "VMw@re123"
		PS C:\> Backup-VCSAToFile -BackupPassword $BackupPassword  -LocationType $LocationType -Location $location -LocationUser $LocationUser -LocationPassword $locationPassword -Comment "This is a demo" -ShowProgress -FullBackup

	
	.NOTES
        You must be connected to the CisService for this to work, if you are not connected, the function will prompt you for your credentials
		If a -LocationType is not chosen, the function will default to FTP.
        The destination location for a backup must be an empty folder (easiest to use the get-date cmdlet in the location)
        -ShowProgress will give you a progressbar as well as updates in the console
        -SeatBackup will only backup the config whereas -Fullbackup grabs the historical data as well
