Sync Folders and files with Powershell and send notification email

I needed a way to sync some files and folders to another disc, as Allwaysync only permits less than 40.000 items per sync.
I came across a nice script from here.

But it did not exactly do what i needed it to do so adjustments were made.
I didnt need it to check the destination against the source, so got rid of that,
and made a way for it to email me the results as it had
finished comparing and syncing.

The script looks like this now:

Param($Source,$Destination)
function Get-FileMD5 {
    Param([string]$file)
    $mode = [System.IO.FileMode]("open")
    $access = [System.IO.FileAccess]("Read")
    $md5 = New-Object System.Security.Cryptography.MD5CryptoServiceProvider
    $fs = New-Object System.IO.FileStream($file,$mode,$access)
    $Hash = $md5.ComputeHash($fs)
    $fs.Close()
    [string]$Hash = $Hash
    Return $Hash
}
# Source from http://bsonposh.com/archives/231

$logfile = "C:\temp\foldersync.log"

function Copy-LatestFile{
     Param($File1,$File2,[switch]$whatif)
     $File1Date = get-Item $File1 | foreach-Object{$_.LastWriteTimeUTC}
     $File2Date = get-Item $File2 | foreach-Object{$_.LastWriteTimeUTC}
     if($File1Date -gt $File2Date)
     {
         write-output "$File1 is Newer… Copying…" | out-file $logfile -Append
         if($whatif){Copy-Item -path $File1 -dest $File2 -force -whatif}
         else{Copy-Item -path $File1 -dest $File2 -force}
     }
     else
     {
         write-output "$File2 is Newer… Copying…" | out-file $logfile -Append
         if($whatif){Copy-Item -path $File2 -dest $File1 -force -whatif}
         else{Copy-Item -path $File2 -dest $File1 -force}
     }
     write-output | out-file $logfile
}

if(!(test-Path $Destination))
{
     New-Item $Destination -type Directory -force | out-Null
}

# Getting Files/Folders from Source and Destination
$SrcEntries = Get-ChildItem $Source -Recurse -Force
$DesEntries = Get-ChildItem $Destination -Recurse -Force

# Parsing the folders and Files from Collections
$Srcfolders = $SrcEntries | Where-Object{$_.PSIsContainer}
$SrcFiles = $SrcEntries | Where-Object{!$_.PSIsContainer}
$Desfolders = $DesEntries | Where-Object{$_.PSIsContainer}
$DesFiles = $DesEntries | Where-Object{!$_.PSIsContainer}

# Checking for Folders that are in Source, but not in Destination
foreach($folder in $Srcfolders)
{
     $SrcFolderPath = $source -replace "\\","\\" -replace "\:","\:"
     $DesFolder = $folder.Fullname -replace $SrcFolderPath,$Destination
     if($DesFolder -ne ""){
         if(!(test-path $DesFolder))
         {
             write-output "Folder $DesFolder Missing. Creating it!" | out-file $logfile -Append
             new-Item $DesFolder -type Directory | out-Null
         }
     }
}

# Checking for Files that are in the Source, but not in Destination
foreach($entry in $SrcFiles)
{
     $SrcFullname = $entry.fullname
     $SrcName = $entry.Name
     $SrcFilePath = $Source -replace "\\","\\" -replace "\:","\:"
     $DesFile = $SrcFullname -replace $SrcFilePath,$Destination
     if(test-Path $Desfile)
     {
         $SrcMD5 = Get-FileMD5 $SrcFullname
         $DesMD5 = Get-FileMD5 $DesFile
         If($srcMD5 -ne $desMD5)
         {
             write-output "The Files MD5′s are Different… Checking Write Dates" | out-file $logfile -Append
             write-output $SrcMD5 | out-file $logfile
             write-output $DesMD5 | out-file $logfile
             Copy-LatestFile $SrcFullname $DesFile
         }
     }
     else
     {
         write-output "$Desfile Missing… Copying from $SrcFullname" | out-file $logfile -Append
         copy-Item -path $SrcFullName -dest $DesFile -force
     }
}

$smtpto = "user@domain.com"
$smtpfrom = "FolderSync@domain.com"
$messagesubject = "FolderSync results $finishtime"
$smtpServer = "smtp.domain.com"


out-file $Logfile -Append

$finishTime = get-date -format "dd-MM-yy HH-mm"
"Backup script finished at $finishTime" | out-file $logFile -Append -Force

$message = New-Object System.Net.Mail.MailMessage $smtpfrom, $smtpto
$message.Subject = $messageSubject
$message.IsBodyHTML = $false
$finished = get-content $LogFile
$message.Body = ( $Finished | out-string )
$message.Body = $Finished
write-host 'Sending email'
$smtp = New-Object Net.Mail.SmtpClient($smtpServer)
$smtp.Send($message)
Write-Host "Email sent"

remove-item $Logfile


After this you can schedule it in task manager:

powershell -command "& 'E:\path to script\scriptname.ps1 X:\source Y:\destination' "
