Last Updated:Aug 28, 2026

To continue using your existing backup data after an OS reinstall or MAC address change, you must reinstall the Local File Backup client with its original activation code.

Procedure

  1. Obtain the activation code of the original client

    Navigate to the Protected On-premises File Sources tab on the Local File Backup page. Find the original client and click View Details in the Actions column. On the client details page, click ┇ > Reinstall to get its activation code.

    Important

    The activation code expires. If the code expires before you activate the client, refresh the page to obtain a new code and try again.

To resolve this, stop the client service and reactivate the client using the original activation code. To do this, follow these steps:

  1. Stop the client service: Perform the corresponding operation based on the operating system.

    • For Linux systems: Run the systemctl stop hbrclient command.

    • For Windows systems: Run services.msc to open Services. Find and stop the Cloud Backup service.

  2. Delete the new client and its backup data: On the Protected On-premises File Sources tab of the Local File Backup page, find the client record that was created with the new activation code. Click View Details in its Actions column. On the client details page, click ┇ > Uninstall.

    Important
    • After you delete the backup, the client and its backup data are deleted and cannot be recovered.

    • Activate the original client and complete a backup to ensure data is available before you delete the new client's backup data.

  3. Reactivate the client: On the Protected On-premises File Sources tab of the Local File Backup page, find the original client and click View Details in its Actions column. On the client details page, click ┇ > Reinstall to get the activation command. Run the command on your server to reactivate the client.
