# How to Use an e3 Storage Bucket with eazyBackup

This guide configures the **eazyBackup desktop application** to store backups in an **e3 Object Storage** bucket.

{% hint style="info" %}
This is **not** e3 Cloud Backup (agents/jobs in the browser). This is the **eazyBackup desktop app** using a custom S3 vault.
{% endhint %}

Connection settings: Connection details.

### Part 1: Create a bucket

1. Sign in to the client area and open **e3 Object Storage**.
2. Go to **Buckets**.
3. Click **Create Bucket**.
4. Enter a **Bucket Name** and **Select Bucket Owner** (Root user or a User whose keys you will use).
5. Submit to create the bucket.

See Buckets for versioning and Object Lock options.

### Part 2: Add a Storage Vault in eazyBackup

1. Open the **eazyBackup** desktop application.
2. Open **Settings → Storage Vaults**.
3. Click **+ (Add)** and choose **Custom**.
4. Name the vault (e.g. `e3 Storage`).
5. **Type of storage** — **S3-compatible**.

#### S3 connection fields

| Field                       | Value                                                                 |
| --------------------------- | --------------------------------------------------------------------- |
| **Hostname**                | `s3.ca-central-1.eazybackup.com` (from **Access Keys → Service URL**) |
| **Region**                  | Automatic (default)                                                   |
| **Access key / Secret key** | From **Access Keys** (Root) or **Users**                              |
| **Bucket**                  | Exact bucket name from Part 1                                         |
| **Subdirectory**            | e.g. `backup-data` (optional prefix inside the bucket)                |

Click **Test Connection**, then **Next** and **Save**.

{% hint style="warning" %}
**Default vault:** The app may ship with a default **eazyBackup** cloud vault. You do **not** have to remove it to add an e3 vault. Only remove the default vault if you intentionally want to stop using hosted cloud storage and understand that protected items pointing at that vault will need reconfiguration.
{% endhint %}

### Part 3: Back up to the vault

Create or edit **Protected Items** and select your new e3 Storage vault as the destination.
