What is DPM (Data Protection Manager) in Microsoft Exchange Server?

In this article, I am going to describe about what is DPM in Exchange server 2016, 2013, & 2010. The full form of DPM is Data Protection Manager, as the name suggest that it is related to the data protection of Exchange server database. But it not just protecting the data by taking regular backup. It also recover the data in case of any disaster, you just need to make sure that all the configurations are properly configured for this.

Prerequisites: DPM

There are following criteria which should be fulfilled before deployment and configuration of DPM for Exchange database protection.

  • First of all make sure the ESEUTIL.EXE as well as ESE.DLL are installed on Exchange server as well as on DPM server.
  • ESEUTIL and ESE should be of same version, if 64 bit is installed on Exchange server, then it is necessary that 64 bit version of ESEUTIL and ESE should be installed on DPM server.
  • In case of any updation in ESEUTIL and ESE on exchange, make sure that the update should be installed on both server. You can find the ESEUTIL and ESE file at below mentioned location in Exchange:
    For Exchange 2016:

    C:\Program Files\Microsoft\Exchange Server\V16\Bin

    For Exchange 2013:

    C:\Program Files\Microsoft\Exchange Server\V15\Bin

    For Exchange 2010:

    C:\Program Files\Microsoft\Exchange Server\V14\Bin

  • Run below mentioned FSUTIL command to create link between ESEUTIL or Exchange and DPM Server.
    fsutil hardlink create "c:\program files\microsoft\dpm\bin\eseutil.exe" "c:\program files\microsoft\Exchange\bin\eseutil.exe"
  • The latest version of Visual C++ Redistributable should be installed.
  • For protection of DAG nodes, it is mandatory that DPM should be installed at node and One DPM server can protect only one Node at a time.
  • DPM protects active as well as passive database of Exchange server.
  • Change minimum frequency for synchronization more than 15 minutes.

Advantages of Deploying DPM with Exchange Server

There are following advantages which you could get after implementation of DPM with Exchange Server:

  • There is no additional database server is required in DAG after deployment of DPM with Exchange.
  • In case of any disaster, with the help of DPM the database could be restored easily.
  • DPM server keeps backup of Exchange database for long time in comparison with 14 days native backup retention time.
  • DPM provides complete backup of all workloads like: Hypervisor, SQL Server, File server, Exchange Server etc.

Monitoring Exchange Server with DPM

After installation and configuration of Data Protection Manager, it is required to set up monitoring notifications and alerts for getting information of any suspicious behavior of Exchange server into your mailbox. There are some process to setup the notification in DPM, which I am going to mention below.

  1. First of all, go through the DPM Administrator Console, and then click on Monitoring, then Actions and then Options.
  2. Now, click on SMTP server and then enter the Server Name, Port Number, and the Email Address in which you want to receive notifications and alerts.
  3. Now, in Authenticated SMTP Server enter username and password of previously entered email address for getting notification.
  4. Now, click on Send Test-Email and enter the email address in which you want to get the notification and then click on OK button to get a test notification message.
  5. For more detailed, click on Options and then Notifications and select type of notifications you want to receive, and in Recipient enter all those email address, whom you want to send the notification messages.
  6. Now again for testing hit Send Test-Email link.

That’s it about What is Data protection manager in this article.

Exception Case

As we have discussed that deployment of DPM would be very useful if your server is hosted in DAG and you don’t want to let the server down for a little span of time. But, if you don’t have a very large scale of business and you can keep you organization continue in case of little span of downtime in a month. Then you need not to put a lot of money after DPM configuration and management.

In case of any disaster, if server goes down and you find that your Exchange database is corrupted then you could use any third party tool which can help you to restore the database.

Conclusion: What is DPM?

The described information in this article is completely related to “What is DPM or Data Protection Manager” and “How it is good to configure with Exchange”. In above sections, we have discussed about the pre-requisites of DPM installation, advantages of DPM, and way to configure DPM for monitoring activities going on Exchange Server. In the last section we have also mentioned an exception situation, in which case, deployment of DPM would be the best.
