Powershell + Robocopy Auto backup executing multiple times - powershell

Question

I've put together this script to detect file changes in a directory, so that whenever the changes take effect the file(s) changed will get backed up right away.
I have also set up an email notification.
The backup works. I can see whenever a file changes it gets copied over to the desired destination, however I am receiving three emails and the robocopy log shows no changes, which leads me to think it's being written three times each time a file changes. So the last time it gets written there will of course be no changes.
Below you can see the code, hope you can help me figure out what's going on.
#The Script
$folder = 'C:\_Using Last Template Approach\' # Enter the root path you want to monitor.
$filter = '' # You can enter a wildcard filter here.
# In the following line, you can change 'IncludeSubdirectories to $false if required.
$fsw = New-Object IO.FileSystemWatcher $folder -Property #{IncludeSubdirectories = $true;NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'}
Register-ObjectEvent $fsw Changed -SourceIdentifier AutoBackUp -Action {
$path = $Event.SourceEventArgs.FullPath
$changeType = $Event.SourceEventArgs.ChangeType
$timeStamp = $Event.TimeGenerated
$datestamp = get-date -uformat "%Y-%m-%d#%H-%M-%S"
$Computer = get-content env:computername
$Body = "Documents Folders have been backed up"
robocopy "C:\_Using Last Template Approach" G:\BackUp\ /v /mir /xo /log:"c:\RobocopyLog.txt"
Send-MailMessage -To "me#me.com" -From "jdoe#me.com" -Subject $Body -SmtpServer "smtp-mm.me.com" -Body " "
# To stop the monitoring, run the following commands (e.g using PowerShell ISE:
# Unregister-Event AutoBackUp
}

i do not change your monitor script just change send mail and copy with copy-item powershell command
$folder = 'c:\sites' # Enter the root path you want to monitor.
$filter = '*.*' # You can enter a wildcard filter here.
# In the following line, you can change 'IncludeSubdirectories to $true if required.
$fsw = New-Object IO.FileSystemWatcher $folder, $filter -Property #{IncludeSubdirectories = $false;NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'}
Register-ObjectEvent $fsw Changed -SourceIdentifier FileChanged -Action {
$name = $Event.SourceEventArgs.Name
$changeType = $Event.SourceEventArgs.ChangeType
$timeStamp = $Event.TimeGenerated
Write-Host "The file '$name' was $changeType at $timeStamp" -fore white
Out-File -FilePath c:\sites\filechange\outlog.txt -Append -InputObject "The file '$name' was $changeType at $timeStamp"
$username=”gmailaccount”
$password=”password”
$smtpServer = “smtp.gmail.com”
$msg = new-object Net.Mail.MailMessage
$smtp = New-Object Net.Mail.SmtpClient($SmtpServer, 587)
$smtp.EnableSsl = $true
$smtp.Credentials = New-Object System.Net.NetworkCredential( $username, $password )
$msg.From = "gmail"
$msg.To.Add(“mail should check notify”)
$msg.Body=”Please See archive for notification”
$msg.Subject = “backup information”
$files=Get-ChildItem “c:\sites\filechange\”
Foreach($file in $files)
{
Write-Host “Attaching File :- ” $file
$attachment = New-Object System.Net.Mail.Attachment –ArgumentList S:\sites\filechange\$file
$msg.Attachments.Add($attachment)
}
$smtp.Send($msg)
$attachment.Dispose();
$msg.Dispose();
Copy-Item c:\sites\$name C:\a\$name }
i check this script work for me if change file content of file first email log file then copy them to destination c:\a\ also you and that file changed to attachment of mail
