What Can I Do If System Configuration Data Fails to Be Backed Up

What Can I Do If System Configuration Data Fails to Be Backed Up


If A FTP server for automatic backup has been configured and no backup data of the FTP server exists at the backup time (2:00 am), the system reports an alarm indicating failed system configuration data backup.

Possible Causes

The parameters for the SSH service of the FTP server are incorrectly configured, causing eReplication failed to connect to the FTP server. As a result, backup fails.

Fault Diagnosis



    1. Use PuTTY to log in to the management server where the eReplication resides.

      Log in to the management server as user root.

    2. Run the following command to disable the automatic exit of PuTTY due to timeout.



      After you run this command, the system continues to run when no operation is performed, resulting a risk. For security purposes, you are advised to run exit to exit the system after completing your operations.

    3. Run the following command to go to the path of the configuration tool:

      cd /etc/ssh

    4. Run the following command to open the configuration file:

      vi sshd_config

    5. Press i to enter the edit mode.
    6. Modify the following parameters in the configuration file to be consistent with information in bold.

      PermitRootLogin yes
      PasswordAuthentication yes
      PermitEmptyPasswords no
      ChallengeResponseAuthentication no
      UsePAM yes

    7. Press ESC, enter :wq, save the modification, and exit the VI Editor.
    8. Run the following command to restart the SSHD service:

      service sshd restart

    9. At the next backup time, check whether the alarm is cleared and backup is successful.

      • If yes, no further action is required.
      • If no, contact Huawei technical support.
