Wrong encryption key

Hi

Would you be able to let me know a list of possible causes and solutions for the below alert for a user on the DLO Conole?

The Desktop Agent computer was configured with an encryption key that is no longer valid.  Any encrypted data stored in the Desktop User Data Folder for this computer has been removed and will be backed up again with a valid key.

Thanks

Jimmy

    When an user is deleted, the configuration data for this user is deleted from the DLO server and also the user data which is present in the NUDF.

    A dialog box is presented when an user is being deleted with the option to delete data from the NUDF.

    If the user data is not deleted from the NUDF, the data + the old encryption key remains. And the only way to restore is by using the "Emergency Restore" method. And when the same user is readded, a new encryption key is created in the NUDF for this user. When the Data Integrity scanner runs, it finds 2 encryption keys (the old one and the new one) and then it gives the message as mentioned in your query. ITs not an error, merely an informative message post a maintenance task.

    If the user data is deleted from the NUDF, the old encryption key is deleted as well. When the same user is readded, a new key is added and newer backups are encrypted with this key. The above mentioned informative message does not appear in this situation.

    Common reasons are if the DLO database was changed or if the specific user was deleted and re-added in DLO.

    Hi VJware

    Thanks a million for you response.

    If a user is deleted and then re-added to the Console, what is the correct sequence to avoid getting the wrong encryption key message? I have come across users are not in the DLO console and re-added them.

    Thanks

    Thanks again VJware for all the helpful information

    So, if users are getting this alert on the console their backup will run ok as this is just an informative message because the Data Integrity scanner finds two key?

    Thanks

    That's right, however do keep in mind, the older backup sets are removed & this may cause an issue if the user wants specific data which was backed up earlier. Else, if there is no such user requirement, the backups will run as usual and the new backup sets are restorable with the new encryption key.
