# Phase 4 GCP - post installation

Before you begin with the CircleCI Server 4.9 post installation phase, ensure you have run through the following:

*   [Phase 1 GCP – Prerequisites](https://circleci.com/docs/server-admin/latest/installation/phase-1-gcp-prerequisites/)
    
*   [Phase 2 GCP - Core Services Installation](https://circleci.com/docs/server-admin/latest/installation/phase-2-gcp-core-services/)
    
*   [Phase 3 GCP - Execution Environments Installation](https://circleci.com/docs/server-admin/latest/installation/phase-3-gcp-execution-environments/)
    

In the following sections, replace any sections indicated by `< >` with your details.

## Backup and restore

Backups of CircleCI Server can be created through [Velero](https://velero.io/) which is detailed in our [Backup and Restore](https://circleci.com/docs/server-admin/latest/operator/backup-and-restore/) documentation.

## Email notifications

Add email notification support by adding the following to `values.yaml`:

`````````
smtp:
  host: <hostname-of-submission-server>
  user: <username-for-submission-server>
  password: <password-for-submission-server
  port: <mail-port>
`````````

## Managing orbs

CircleCI Server installations include their own local orb registry. This registry is private to the server installation. All orbs referenced in project configs reference the orbs in the _server_ orb registry. You are responsible for maintaining orbs. This includes:

*   Copying orbs from the public registry.
    
*   Updating orbs that may have been copied previously.
    
*   Registering your company’s private orbs, if you have any.
    

For more information and steps to complete these tasks, see the [Managing Orbs on Server](https://circleci.com/docs/server-admin/latest/operator/managing-orbs/) guide.
