# What is e3 Object Storage

What e3 Object Storage is, how Root users and Users work, and how it differs from e3 Cloud Backup.

e3 Object Storage is **managed S3-compatible storage** in the eazyBackup client area. You get buckets, API keys, usage charts, and billing in one place — without running your own object store.

### What you can do

* Create **buckets** and upload or browse objects in the **Bucket Browser**
* Issue **Access Keys** for the Root user and create **Users** with isolated buckets and scoped keys
* Monitor **usage**, **ingress/egress**, and **billing** per service period
* Connect backup apps, scripts, and appliances via the standard S3 API

### Root user vs Users

Your service has one **Root user** (the primary identity on the account) and optional **Users** you create for isolation.

|                     | Root user                                          | Users                                      |
| ------------------- | -------------------------------------------------- | ------------------------------------------ |
| **Access keys**     | One key pair (create or rotate on **Access Keys**) | Multiple keys per user                     |
| **Key permissions** | Always full access                                 | Per key: Full, Read/Write, Read, or Write  |
| **Buckets**         | Own buckets only                                   | Own buckets only                           |
| **Cross-access**    | Cannot access a User’s buckets                     | Cannot access Root or other Users’ buckets |

All storage and transfer for Root and Users is **billed to your client account**. Usage is not split into separate invoices per User.

### Product boundaries

{% hint style="warning" %}
Keep these products separate when reading docs or opening tickets:
{% endhint %}

* **e3 Object Storage** (this section) — S3 buckets, keys, browser, object storage billing.
* **e3 Cloud Backup** — local agent, cloud backup jobs, vaults, Microsoft 365.
