The Number of Metabase Backup Files Increases in the System32\Inetsrv\Metaback Directory on Neverfail For IIS or Neverfail for Sharepoint Installations

Follow

Summary

This knowledgebase article contains important information relating to all Neverfail for IIS and Neverfail for SharePoint deployments that were installed using versions of the AM(X) up to and including the following versions:

  • Z-Sw-A1009-2005-09-12-IIS.zip
  • Z-Sw-A1014-2005-09-20-SharePoint.zip


More Information

Neverfail for IIS and Neverfail for SharePoint create Metabase backups each time the application is stopped. This provides a restore point to protect against:

  • Data corruption
  • Incorrect configuration changes

Symptoms

The number of Metabase Backup Files Increases in the System32\Inetsrv\Metaback Directory on Neverfail For IIS or Neverfail for SharePoint Installations.

Cause

The backups are created in %systemdrive%\system32\inetsrv\Metaback directory and are named NeverfailIIS.mdx, where x is the backup index.

On affected installations, the number of backups will grow unchecked. This will result in a large amount of files accumulating in the Metaback directory. Neverfail recommends removing the old backups to conserve disk space.

Resolution

In order to manage these backups automatically, Neverfail has released a new filter discovery utility that will manage the creation of backups so that a maximum of three Neverfail created backups will exist at any one time. An older backup file will be deleted in preference for a new backup.

Please note Neverfail will only delete backups where the filename starts NeverfailIIS, and will not delete backups created manually or as part of an existing backup procedure.

Instructions:

  1. Download KB415 - FilterDiscoveryUtilities.zip .
  2. Extract the contents in to %drive%\neverfail\r2\bin\
  3. Locate the following script depending upon your installation
    • For installs with SQL Server edit %drive%\neverfail\r2\scripts\sqlserver\stop.bat
    • For all other installs edit %drive%\neverfail\r2\scripts\iisserver\stop.bat
  4. Change the following line:

From: "discoverFilterIISServer.exe /f=backup /o=yes"

To: "discoverFilterIISServer.exe IISServer /f=backup /o=yes"


Applies To

As Indicated Above
