Backup to network folder, display message if folder not available. [Powershell]

This example backups Thunderbird profiles to precreated network share. It can be added to task scheduler. It sends net message to current user if network share does not exist.

$name="user"
$backupDir = "\\server\backup\workstations"
$backupFolder = $backupDir + "\" + $name + "\"
$date = get-date -Format ddd



echo $backupFolder
echo $env:APPDATA/Thunderbird
cd $env:APPDATA/Thunderbird


if (-Not (Test-Path -Path $backupFolder)) { 

msg.exe $env:UserName "Path[$backupFolder] not found, unable to backup"

return 0x10
}



if (-Not (Test-Path -Path $backupFolder$date)) {
New-Item -Path "$backupFolder$date" -ItemType Directory
}
else
{
echo "Path: $backupFolder$date already exists, skipping"
