title: Object Versioning
---

EOS supports **Object Versioning**, allowing you to preserve, retrieve, and restore every version of every object stored in a bucket. This is especially useful to protect against accidental overwrites or deletions.

### Enable Versioning

To enable versioning:

1. Select your bucket from the **Manage Object Storage** list.
2. Open the **Actions** menu and select **Object Versioning**.
3. Toggle the **Enable Versioning** switch.

Once enabled, every new upload of an object will create a new **version** instead of overwriting the existing file.

---

### Viewing Object Versions

To view previous versions of an object:

1. Open the **Objects** tab of your bucket.
2. Click on **See all versions** above the object list.
3. You’ll now see all available versions of each object with their unique **version ID**, **timestamp**, and **size**.

---

### Download a Previous Version

To download an older version of an object:

1. In the **Objects > See all versions** view, locate the desired object.
2. Click the **three-dot menu** next to the version.
3. Choose **Download** or **Generate Presigned URL** depending on your need.

---

### Delete a Specific Version

To delete a particular object version:

1. In the **See all versions** view, open the **three-dot menu** next to the version.
2. Click **Delete version**.

> 🗑️ Deleting a version only removes that specific version, not the entire object.

---

### Disable Versioning

You can **suspend** versioning but cannot delete version history retroactively.

To disable (suspend) versioning:

1. Open the **Actions** menu and select **Object Versioning**.
2. Toggle the **Disable Versioning** switch.

> 🚫 Suspended buckets will **stop creating new versions**, but all existing versions will remain intact.

---

### Use Cases

* **Recover accidentally deleted files**
* **Track changes to critical data over time**
* **Audit and rollback configurations**

:::info Note
You are billed for **all versions** of an object. Consider using lifecycle rules to automatically clean up older versions if storage costs are a concern.
