Langmeier Backup FAQ

How to make open file backups work

Wie kann eine Backup-Software die Datensicherung offener Dateien (z.B. offene Microsoft Outlook-Datei) durchführen? Hier die Aufklärung, wie es funktioniert.

An important topic in data backup is the backup of open files. Many backup programs adorn themselves with the feature of being able to back up open files, but in fact, unfortunately, this does not always work.

Some programs, for example Microsoft Outlook, lock their working files so that no other program can access the file while the user is working with it. As a result, the backup software has a problem because file access is denied.

In Windows, there are many files that are used from time to time and then locked. For example, if you try to backup the application data or the local settings, you will find that some files cannot be backed up there. Such locked files are caused, for example, by Windows Search, which regularly scans the data on the PC in the background and creates a search index from it.

A modern backup software like Langmeier Backup can backup most of the open and locked files if the following conditions are met:

  • The option "Backup also open files" is enabled (default).
  • The source volume is an NTFS formatted volume.
  • Langmeier Backup runs with administrator permissions. (Domain administrators may not work, in which case a local admin is required).
  • The open file must be on the same computer as Langmeier Backup.
  • The"Volume Shadow Copy" (VSS) service must be enabled. Startup type: "Manual".

Also note the following:

Status VSS service

If it does not work despite all, then probably the VSS service is defective. Send a message to the customer service - we can send you a program which repairs the VSS service of Windows.

What is the VSS service?

To backup open files, the separate VSS (Volume Shadow Copy) service must be active on the PC. The service waits in the background and provides a so-called Windows shadow copy on request of the data backup program. This is a copy of the last valid state of the file.

We recommend that the data backup program uses the service already built into Windows, then the computer resources are not additionally burdened by a second service that does exactly the same thing. The VSS service has been built into the Microsoft operating system since Windows XP and is enabled by default.

Close Outlook and other applications before backing up data

Some backup users prefer to play it safe and close Outlook and other applications before backing up data.

This tip works for Langmeier Backup Business, Server and V-flex versions.

In the main Langmeier Backup window, click on"Tools" and then on"Edit Scripts". The script editor opens. Below the script editor, click the"New" button to create a new script. Paste the following script into the script editor:

'Exit Outlook
Set oWmi = GetObject("winmgmts:")
sSql ="select * from Win32_Process where name='outlook.exe'"
Set oResult = oWmi.Execquery(sSql)
For Each oProcess In oResult
iRet = oProcess.Terminate(1)
Next
Set oWmi = Nothing
'Finally wait a bit:
Sleep 1

Now save this script by clicking on"Save as". This button is located below the script editor. Enter the desired file name, for example "Close Outlook".

In the main Langmeier Backup window, click the"Backup" tab at the top. Insert the newly created script by clicking on the text at"Add" and then on"Script".

After confirmation, the script will appear in the backup job. You can move it to the top of the job by pressing the minus (-) key or by using the right mouse button.

Restarting the program after the backup

You can use the following script to restart the program after the backup. Please adapt the program path in the second line to your program resp. to your Office version:

'Restart Outlook:
Set WshShell = GetObject("WScript.Shell")
WshShell.Run """C:\Program Files\Microsoft Office\Office14\Outlook.exe"", 9
