+# Backup Management
+
+Our platform uses [Velero](https://velero.io/) for backup and recovery operations. Velero provides a simple and reliable way to back up and restore Kubernetes cluster resources and persistent volumes.
+
+## Automated Backups with Velero
+
+By default, Velero is configured to automatically back up specific namespaces every day at 02:00 UTC, with a retention policy of 7 days. The namespaces included in the default backup schedule are:
+
+- `harbor`
+- `vault`
+
+The backup schedule is defined in the following file: 
+
+```markdown
+gitops-pipelines/delivery/clusters/cc-cluster/core-services/components/velero/backup-schedule.yaml
+```
+
+
+### Customizing Backup Schedules
+
+To add more namespaces to the backup schedule or adjust the backup settings, you can update the existing `backup-schedule.yaml` file or create a new one. Changes made to this file will be detected by ArgoCD and applied automatically, ensuring your backups are always up to date.
+
+## Restoring from Backup
+
+In the event that you need to restore from a backup, follow the steps below.
+
+### Disable ArgoCD Auto-Sync
+
+Before initiating a restore, it's important to disable ArgoCD's auto-sync feature to prevent it from overwriting the restored resources. You can disable auto-sync by:
+
+- Editing the ArgoCD application manifest in the GitOps repository.
+- Using the ArgoCD UI.
+- Using the ArgoCD CLI.
+
+> **Recommended Approach:** Update the ArgoCD application file in the GitOps repository. This method ensures that changes are version-controlled and easily trackable.
+
+### Install and Configure Velero Locally
+
+1. **Install Velero CLI:**
+
+   Follow the [official Velero installation guide](https://velero.io/docs/main/basic-install/) to install the Velero CLI on your local machine.
+
+2. **Configure Cluster Context:**
+
+   Ensure your kubeconfig is set to the cluster you wish to restore:
+
+   ```bash
+   kubectl config use-context <your-cluster-context>
+
+3. **Validate Velero Access:**
+
+   Verify that Velero can communicate with your cluster:
+
+   ```bash
+   velero version
+    ```
+
+
+### Perform the Restore
+
+1. **List Available Backups:**
+
+   View all available backups to find the one you need:
+
+   ```bash
+   velero backup get
+   ```
+2. **Initiate the Restore:**
+
+  Use the following command to start the restore process::
+
+   ```bash
+   velero restore create --from-backup <backup-name>
+   ```
+   Replace <backup-name> with the name of the backup you wish to restore. For example:
+
+   ```bash
+   velero restore create --from-backup daily-backup-20241120020019
+   ```
+3. **Monitor the Restore Process:**
+
+  Check the status of the restore:
+
+   ```bash
+   velero restore get
+   ```
+   For detailed information:
+   ```bash
+   velero restore describe <restore-name>
+   ```
+   Replace <restore-name> with the name of the restore operation initiated.
+
+### Re-enable ArgoCD Auto-Sync
+
+After confirming that the restore was successful and the cluster is functioning as expected, re-enable ArgoCD's auto-sync feature to maintain the desired state of the cluster.
+
+## Additional Considerations
+
+- **Data Consistency:** Ensure that no conflicting operations are occurring during the restore to prevent data inconsistencies.
+- **Resource Quotas:** Verify that resource quotas and limits are sufficient for the restored resources.
+

+
+By following these steps, you can effectively manage backups and restores within your Kubernetes clusters, ensuring data integrity and continuity of service.
