Step 7. Specify User Credentials
At the Guest OS step of the wizard, specify a user whose credentials Veeam Backup & Replication will use to create the Default Administrator account on the Veeam Backup for Google Cloud appliance.
For a user to be displayed in the Create the following administrator credentials drop-down list, it must be added to the Credentials Manager. If you have not added a user to the Credential Manager beforehand, you can do it without closing the New Veeam Backup for GCP Appliance wizard. To add a new user, click either the Manage accounts link or the Add button, and then specify a user name, password and description in the Credentials window.
