# Backing Up RDS Instance

#### Backing Up RDS Instance

GreenNode vDB supports two methods for data backup: on-demand (manual) and daily automatic backups at a scheduled time.

***

### **A. On-demand Backup (Manual Backup)**

When you need to create a backup, go to the backup management screen for the vDB Relational service [here](https://vdb.console.vngcloud.vn/relational/backup). This screen will list all backups (manual & auto) for all RDS Instances in your account.

#### Steps to create a backup:

1. Click on the **Create Backup** button. In the **Create Backup** screen, provide the following information:

   * **Backup Name**: Give a name to this backup.

   * **Database Instance Name**: Choose the RDS Instance you want to back up.

   * **Backup Type**: You have two options:
     * **Full Backup**: vDB will back up all your data.
     * **Incremental Backup**: vDB will only back up the changes in your database. The size of an Incremental Backup is much smaller than a Full Backup. However, an Incremental Backup requires you to have created at least one Full Backup for the RDS Instance beforehand.

   * **Backup Parents**: If you chose Incremental Backup, you must specify a Backup Parent for this Incremental Backup. The Backup Parent can be a Full Backup or a previous Incremental Backup.

   > **Note**: Incremental Backup depends on the Backup Parent. If you delete the Backup Parent, all associated Incremental Backups will be invalidated and deleted.
2. Once all information is correct, click **Create**.
   * Initially, the backup status will be **BUILDING**.
   * Once the backup is complete, the status will change to **COMPLETED**.

#### Additional:

You can also create a **Manual Backup directly** from the **Database Management** screen. Click on an RDS Instance, go to the **Backup** tab, and scroll down to the **Backup List**. You can then click **Create Backup** from here.

***

### **B. Auto-Daily Backup**

vDB supports automatic daily backups at a pre-scheduled time.

#### To check if an RDS Instance is configured for auto-daily backup:

1. Go to the **Database Management** screen.
2. Select an RDS Instance, then click the **Backup** tab.
3. In the **Backup Information** section, check if **Automatic backup** is enabled. If it is, it means the RDS Instance is configured for daily automatic backups.

#### To configure Auto-Daily Backup:

You have two options:

* **Configure it during the RDS Instance creation** (see guide for RDS Instance setup).
* **Modify it in the Database Management screen**:
  1. Go to the **Database Management** screen, select the RDS Instance you want to configure.
  2. Click **Edit Database**.
  3. Scroll down to **BACKUP SETTINGS** and configure the following options:
     * **Automatic daily backup**: Enable or disable this feature.
     * **Backup retention period**: Set the retention period for the automatic backups. Backups older than this period will be deleted to save storage space.
     * **Backup time**: Set the time for the automatic backup process. GreenNode recommends selecting a time that is least busy for your system.

4. After verifying the details, click **Save** to apply the changes. Wait a moment for the process to complete.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.vngcloud.vn/vng-cloud-document/vdb/relational-database-service-rds/working-with-rds/sao-luu-du-lieu-cua-rds-instance.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
