Exchange Protection Manager (EPM) Lite

Using Exchange Protection Manager (EPM) Lite allows GOexchange users to create a backup of their databases prior to GOexchange maintenance being run.  Refer to the following sections to learn what system requirements are needed to run EPM Lite and how to utilize it to get the most protection out of your GOexchange software.

Minimum System Requirements

In order to use EPM Lite, first it must reside on the Exchange server you wish to back up.  That server should have the following minimum requirements:

WARNING: Installation of the .NET Framework stops the IIS Admin Service which will affect Exchange services.  Therefore, if you need to install this update, please plan accordingly to avoid unplanned downtime.

Configure Exchange Protection Manager (EPM) Lite

Follow the instructions below to configure EPM Lite;

  1. Navigate to the EPM Lite folder which can be found here: ..<Installation Path>\Agents\EPM Lite

  2. Double click EPM Lite.exe to launch.

  3. Select the Store(s)/Storage Group(s) you wish to include in the backup.

NOTE: For Exchange 2007 and below, you will have to back up the entire storage group.

  1. Click on the button to select where to store the backup.

  1. Now click Generate GE Batch and select where to save the batch file.

  1. The batch file having been created, click Close.

Run Exchange Protection Manager (EPM) Lite Jobs

Now that you have created the batch file, we have to attach it to the applicable maintenance jobs.

  1. Open the GOexchange Client Console and edit the desired GOexchange maintenance job.

  1. On the Custom Processes page, click the under Pre-Maintenance Custom Process.

  1. Navigate out to where you saved the batch file, select it, and click OK.

  1. Adjust the Timeout for the initial run according to the size guidelines below:

NOTE: The Timeout is the amount of time that GOexchange will give the operation to finish before it continues its maintenance job.

If the operation finishes before the Timeout has concluded, the maintenance job will continue immediately, provided the Process Completion option is checked.

It is possible to run the Custom Process without a Timeout; however, this is not recommended.

NOTE: Different system and configurations can make some machines take longer than others.  We recommend you start with the guidelines provided and adjust from there based on actual times it takes to run the job.

  1. Apply the changes and click OK.  The EPM Lite Pre-Maintenance job is ready to run.


If the EPM Lite backup job fails, you can review the EPM Lite job logs to see why.  They are saved in the EPM Lite directory.  If you installed GOexchange to its default destination on a 32-bit machine, this would be C:\Program Files\Lucid8\GOexchange\Agents\EPM Lite.

Problem: The EPM Lite backup job failed with the error Microsoft Exchange Writer is not available.

  1. Restart your server.

  2. Re-run the command vssadmin list writers and confirm the VSS Writers are present.
