Email notifications for NTBACKUP


Jump to: navigation, search

The native backup software with Windows is useful to use when no paid-alternatives are available and in many ways remains the arguably most reliable method for backing up Exchange, however it cannot natively send emails notifying a system administrator whether or not a backup has completed. Even in well-funded environments it is recommended to have a secondary backup contingency in case the primary setup fails upon restore.

Email notifications for NTBACKUP are achieved by using a VBS script which is scheduled to be run straight after the backup has finished. This utilises a command-line SMTP mailer programme to send an email from the most recent NTBACKUP log file.


1. Install the command line email Blat: Its location can be anywhere but the path already in the VBS script is C:\BackupNotify\full\blat.exe
2. Setup initial details for blat: blat -install <smtp server> <from address> For example: blat backups@company.local
3. Save the below script to the PC where backups are performed as NTBackupNotify.vbs and adjust the variables as necessary:

'Adapted from a script by Gary Thorne
'Schedule this script to run straight after an NTBACKUP finishes, uses Blat to send out emails.
Const strLogDir = "C:\Documents and Settings\schedadmin\Local Settings\Application Data\Microsoft\Windows NT\NTBackup\data\"
Const strMailSender = "backups@company.local"
Const strMailRecipient = "admin@company.local"
Const strBlat = "C:\BackupNotify\full\blat.exe"
Const strBlatLog = "C:\backupnotify\ntbackuphandler.log"
Const strsubject = "Backup report"

Sub Main()
	Dim fso, WshShell, fldLogs, filLog, strCmd, sFileBuffer, strfail

	Set fso = CreateObject("Scripting.FileSystemObject")
	Set WshShell = WScript.CreateObject("WScript.Shell")
	Set fldLogs = fso.GetFolder(strLogDir)
	For Each filLog In fldLogs.Files
		If DateDiff("n", filLog.DateLastModified, Now) < 5 Then
			strCmd = "cmd /c type " & Chr(34) & filLog.Path & Chr(34) & "|" & strBlat & " -subject " & Chr(34) & strsubject & Chr(34) & " -f " & strMailSender & " -to " & strMailRecipient & " -log " & strBlatLog
			Wscript.echo strCmd

			WshShell.Run strCmd

		End If
	Set fldLogs = Nothing
	Set WshShell = Nothing
	Set fso = Nothing
End Sub


4. Create a new BAT file which runs the command line that was previously scheduled to be run by itself followed by the NTBackupNotify.vbs script. For instance:

@echo off
rem BAT script to run NTBackupNotify.vbs script after previous command has completed.
<NTbackup command here>
cscript NTBackupNotify.vbs

NTBACKUP will cause the shell to wait until it has finished as the process is not run in the background; always ensuring that the VBS script is run after NTBACKUP has finished.
5. Create schedule as required.
