Lost Encryption Password

Encrypted backups can only be decrypted with an encryption password that is typically known only to you. A lost or forgotten password cannot be recovered.

If you lose the encryption password, you cannot use your previous backups without the encryption password. Therefore, create a new backup plan immediately to create new backups that you can access.

Server Does Not Appear in the Backup Console Despite Successful Installation of Cyber Protection Agent

In some cases, the server does not appear in the Backup Console after the Cyber Protection Agent is successfully installed. To display the server in the Backup Console, delete the existing registration, if any, and perform a manual registration of the server.

Please Note

The registration will fail if the Cyber Protection Agent has already been registered.

Guided Steps

  • Log in to the server as an administrator.

  • To open the Run window, press the key combination [Windows key] + [R].

  • To open the Command Prompt, type cmd and click OK.

  • Change to the folder C:\Program Files\BackupClient\BackupAndRecovery. To do this, type the following command:

    cd C:\Program Files\BackupClient\BackupAndRecovery

  • To delete the existing registry, enter the following command:

    C:\Program Files\BackupClient\RegisterAgentTool\register_agent.exe -o unregister

  • To start the manual registration, enter the command below and replace the wildcards with the backup console username and password.

    C:\Program Files\BackupClient\RegisterAgentTool\register_agent.exe -o register -t cloud -a https://backup.ionos.com -u USERNAME -PASSWORD
