Script: Backup database with email notification

Version 1.3 - May. 31, 2024

This script performs full and transaction log backups of the Mobile database and sends email notifications.



$serverName = "TFS"

$databaseName = "Mobile"

$backupPath = "\\Backup"

$timestamp = (Get-Date).ToString("yyyyMMddHHmmss")

$logFilePath = "$backupPath\MobileBackupLog_$timestamp.log"

Email configuration

$smtpServer = "ded4829.inmotionhosting.com"

$smtpPort = 587

$from = "donotreply@email.alliancewebpos.com"

$to = "dmarquez@asi-dev6.com"

$subject = "Mobile Backup Notification"

$mailUsername = "donotreply@email.alliancewebpos.com"

$mailPassword = "!D0n0tR3pLyp4zz82!x!"

Function to log messages to a file

function Log-Message {

param (




Add-content -Path $logFile -Value "$([DateTime]::Now) - $message"


Function to run a SQL command using sqlcmd and log the result

function Run-SqlCommand {

param (







try {

    $cmd = "sqlcmd -S $server -Q `"$query`""

    Invoke-Expression $cmd

    if (Test-Path $filePath) {

        Log-Message "Successfully created $backupType backup file: $filePath" -logFile $logFile

    } else {

        Log-Message "$backupType backup file not found: $filePath" -logFile $logFile



catch {

    Log-Message "Error executing $backupType backup: $query. Error: $_" -logFile $logFile



Function to send email notification

function Send-EmailNotification {

param (











try {

    $smtpClient = New-Object Net.Mail.SmtpClient($smtpServer, $smtpPort)

    $smtpClient.EnableSsl = $true

    $smtpClient.Credentials = New-Object System.Net.NetworkCredential($username, $password)


    $mailMessage = New-Object Net.Mail.MailMessage

    $mailMessage.From = $from

    $to.Split(",") | ForEach-Object { $mailMessage.To.Add($_.Trim()) }

    $mailMessage.Subject = $subject

    $mailMessage.Body = $body



    Log-Message "Email notification sent successfully." -logFile $logFile

} catch {

    Log-Message "Failed to send email notification. Exception type: $($_.Exception.GetType().FullName)" -logFile $logFile

    Log-Message "Exception message: $($_.Exception.Message)" -logFile $logFile

    Log-Message "Stack trace: $($_.Exception.StackTrace)" -logFile $logFile


    if ($_.Exception.InnerException) {

        Log-Message "Inner exception type: $($_.Exception.InnerException.GetType().FullName)" -logFile $logFile

        Log-Message "Inner exception message: $($_.Exception.InnerException.Message)" -logFile $logFile

        Log-Message "Inner exception stack trace: $($_.Exception.InnerException.StackTrace)" -logFile $logFile




Ensure backup directory exists

if (-not (Test-Path $backupPath)) {

New-Item -Path $backupPath -ItemType Directory


Create a timestamp for the backup filenames

$backupPathFull = "$backupPath\Mobile_Full_$timestamp.bak"

$backupPathTrn = "$backupPath\Mobile_Log_$timestamp.trn"

Full backup T-SQL command

$backupFull = "BACKUP DATABASE [$databaseName] TO DISK = N'$backupPathFull' WITH NOFORMAT, NOINIT, NOSKIP, REWIND, NOUNLOAD, STATS = 10"

Transaction log backup T-SQL command

$backupTrn = "BACKUP LOG [$databaseName] TO DISK = N'$backupPathTrn' WITH NOFORMAT, NOINIT, NOSKIP, REWIND, NOUNLOAD, STATS = 10"

Perform the full backup

Log-Message "Starting full backup of database '$databaseName'..." -logFile $logFilePath

Run-SqlCommand -server $serverName -query $backupFull -backupType "full" -filePath $backupPathFull -logFile $logFilePath

Perform the transaction log backup

Log-Message "Starting transaction log backup of database '$databaseName'..." -logFile $logFilePath

Run-SqlCommand -server $serverName -query $backupTrn -backupType "transaction log" -filePath $backupPathTrn -logFile $logFilePath

Final log message

$backupStatus = "Success" # Assume success unless an error is encountered

Log-Message "Backup process completed with status: $backupStatus." -logFile $logFilePath

Read the content of the log file

$logFileContent = Get-Content $logFilePath -Raw

Send email notification

$emailBody = @"

Backup process for database '$databaseName' completed.

Backup files:

  • Full backup: $backupPathFull
  • Transaction log backup: $backupPathTrn

Log file content:



try {

Send-EmailNotification -smtpServer $smtpServer -smtpPort $smtpPort -from $from -to $to -subject $subject -username $mailUsername -password $mailPassword -body $emailBody -logFile $logFilePath

} catch {

$backupStatus = "Failed"

Log-Message "Failed to send email notification. Backup status: $backupStatus. Exception: $_" -logFile $logFilePath

    $backupPath = "\\Backup"

    If you want to backup to an UNC path then you have to use double-backslash; fix that first =>

    $backupPath = "\\\Backup"

    Hi @Dyan Marquez ,

    I tested your Send-EmailNotification function with active email via smtp.outlook.com and it works fine. It looks like a problem with the internal configuration of the SMTP server that you have provided.

    If this is indeed the case, please mark my answer as "Accepted" and perhaps come back and share the solution.
