Exchange Server 2019/2016/2013 Disaster Recovery Plan

Unexpected problems with Exchange Server can bring business operations to a halt—especially when email, calendars, and scheduling rely entirely on it. Issues like hardware failure, sudden power loss, or malware attacks can happen without warning and cause major disruptions. In industries such as finance, healthcare, and government, even a short interruption can lead to data loss, missed deadlines and compliance issues.

To avoid these risks, it's important to have a clear disaster recovery plan tailored to your version of Exchange Server—whether it’s 2019, 2016, or 2013. A solid plan ensures you can quickly recover mailbox data, databases, and log files in the event of a failure. This is where EdbMails EDB to PST Converter proves invaluable. It allows you to extract mailbox data from corrupt or offline EDB files, even when the Exchange server is completely unavailable.

Recovery Plan for Exchange Server

This step-by-step guide will show you how to handle Exchange Server failures—from finding out what went wrong to getting your mail system up and running again. With the right tools and approach, you can reduce downtime and keep your business communications running smoothly—even during unexpected disruptions.

How to protect an Exchange server from disasters?

The following methods help you create an Exchange server disaster recovery plan and apply it to your environment.

  1. Plan 1: Backup Exchange server data with Windows Server Backup

    Windows Server Backup (WSB) is a built-in utility in Windows Server designed to back up volumes and Exchange servers. However, WSB performs backups at the volume level, meaning it requires the entire volume to be backed up in order to perform application-level backup and restore. This makes it essential to back up the full volume to ensure the integrity and recoverability of Exchange server data during a restore operation.

    Note: When using Windows Server Backup (WSB) to take a backup, you may encounter an error message indicating an "Exchange database consistency check failure" if the EDB file is corrupted. In such instances, it's crucial to repair the database file before attempting to proceed with the backup to ensure successful data recovery and integrity.

      Learn more about the Windows Server backup and its features

    The following steps describe how to perform backup with WSB:

    • Step 1: Start Windows Server Backup as an administrator
    • Step 2: Select the required Backup option under Local Backup

      You have two options to choose from, Backup Schedule and Backup Once

    • Step 3: In the Select Backup Configuration page select Custom

      For a complete backup of all the server data click on Full server. If you want to backup only the database and its related files, then the Custom option should be sufficient.

    • Step 4: In the Select Items for Backup page, click Add Items

      When selecting items, ensure that you select the complete volume and not just the folder where the files are located. For the application-level restore operation it is necessary to select the entire volume.

    • Step 5: Click Advanced Settings to change the VSS settings and add Exclusions

      In the Exclusions tab in the Advanced Settings page, add any files or folders to exclude from the backup. In the Volume Shadow Copy tab (VSS), select VSS full backup.

    • Step 6: Schedule the backup (optional)

      If you have selected the Backup Schedule option in Step 2, you can specify the backup time for the job to run automatically.

    • Step 7: Specify the backup Destination Type

      In this step, you can choose the destination location to save the backup. The following three options are available.

      • Backup to a hard disk that is dedicated for backups (recommended)
      • Backup to a volume
      • Backup to a shared network folder
    • Step 8: Review the backup settings and start the backup

      In the Confirmation page, review the selections and settings such as Backup Time, Files excluded and Advanced options. Finally click Backup to start the operation.

  2. Plan 2: Upgrade your computer hardware and storage space

    Low disk space is a common cause of Exchange Server failures and database corruption. When the server runs out of available disk space, it cannot write new transactions to the database, which can cause the database to dismount and potentially become corrupted. To prevent this issue, it's recommended to either upgrade to a higher-capacity drive or move the database to a different volume with adequate free space.

    Here are some best practices for managing Exchange Server storage effectively:

    • For a standalone Mailbox server, store transaction log files on a RAID-1 (Redundant Array of Independent Disks)
    • If disk space is limited, enable circular logging to reduce log file buildup by overwriting older transaction logs automatically.
    • Use dedicated storage for Exchange data and avoid sharing the same physical disks with other applications to prevent performance issues and conflicts.

     See Exchange server storage configuration options for single and multiple databases per volume.

  3. Plan 3: Set up a Database Availability Group

    A Database availability group (DAG) is a set of Exchange servers that provides automatic database-level recovery from server or network failures. DAG’s are supported in all the latest Exchange servers and creating a DAG improves site resilience and provides automatic recovery during an Exchange server disaster.

     See steps to create a DAG from the Exchange admin center

  4. Plan 4: Perform a periodic Exchange database health checkup

    It’s important to regularly check the health of your Exchange database to keep things running smoothly and catch problems early. Exchange servers can sometimes run into issues like Jet Engine errors, which may cause the database to shut down improperly—known as a Dirty Shutdown. This can put your data at risk. To prevent data loss and keep your server reliable, you should keep the Exchange environment in good shape and create regular backups by exporting mailboxes from the EDB file. These simple, proactive steps help protect your data and make it easier to recover if something goes wrong with the server.

     See steps to check the health of an Exchange database

  5. Plan 5: Perform a recovery with a Recovery database

    A Recovery Database (RDB) in Exchange Server lets you mount a backup copy of your mailbox database such as one created using Windows Server Backup, without affecting the active database. This is useful when your Exchange server fails or data needs to be recovered, as you can restore mailbox content directly from the backup. Keep in mind, this feature is only available in Exchange Server 2016 and newer versions.

     See steps to restore Exchange mailboxes from recovery database

  6. Plan 6: Perform Database portability and Dial tone portability

    Another method for Exchange server disaster recovery is to use the database portability feature, which enables you to move the database to any other Exchange server with the same database schema. It reduces the recovery times for failure scenarios.

     See steps to move mailbox database using database portability

    In the dial tone portability feature, you create a temporary mailbox for sending and receiving messages while the original mailbox is restored. This method involves creating an empty database on the Exchange server to replace the failed database.

     See steps to perform a dial tone recovery in Exchange

  7. Plan 7: Manage the Messaging policy and compliance

    Messaging policy and compliance in Microsoft Exchange help you manage the lifecycle of email communication, ensuring that messages are retained to meet legal, regulatory, and business requirements. These features are critical for preserving data in the event of investigations, litigation, or unexpected server disasters. Implementing a well-defined messaging policy enables smoother recovery and restoration of Exchange data. For instance, enabling the In-Place Archiving feature allows users to access older email data without relying on external .pst files. Additionally, configuring In-Place Hold protects messages from accidental deletion or unauthorized changes, while retention policies ensure that emails are preserved for a specified duration.

     See Messaging policy and compliance and Data Loss Prevention in Exchange server.

  8. Plan 8: Convert the EDB file to PST with EdbMails

    Even with all the right precautions in place, Exchange Server can still crash, leaving the database inaccessible and administrators scrambling for a quick recovery. In such stressful situations, immediate data restoration becomes a top priority—and fortunately, it’s possible with the help of a reliable third-party solution.

    EdbMails, a Microsoft-partnered Exchange recovery toolkit, is designed to recover mailbox data from corrupted or unmountable Exchange databases.

  10. Plan 10: Perform a test restore of the backup

    Once you’ve created a backup using Windows Server Backup and EdbMails, it’s important to perform a test restore to confirm everything works as expected. One key limitation of Windows Server Backup is that it may not recognize or restore a backup if the EDB file is corrupted.
