# Bucket settings
Source: https://docs.infraista.com/en/data-storage/object-storage/bucket-settings



A bucket's **Settings** tab holds everything you can change after creating it. Its name and region are
fixed.

## Access and versioning [#access-and-versioning]

**Public read** and **Versioning** switches save right away.

### Versioning [#versioning]

With versioning on, overwriting or deleting an object keeps its earlier version, so you can restore it
from the **Files** tab. Once turned on, versioning can only be **suspended**:

| State         | What happens                                                                                  |
| ------------- | --------------------------------------------------------------------------------------------- |
| **Enabled**   | New versions are kept every time an object changes                                            |
| **Suspended** | New changes replace objects, but versions kept earlier stay stored (and billed) until deleted |
| **Off**       | Objects are replaced when overwritten                                                         |

Old versions use storage and are billed like any data. When a bucket keeps old versions, its Overview
shows how much space they use, with **Delete old versions now** (permanently deletes them; current files
aren't touched) and a shortcut to delete them automatically after a number of days.

## Size limit [#size-limit]

Set **Limit (GB)** to refuse uploads once the bucket reaches that size (at least 1 GB), then **Save**.
**Remove limit** takes it off.

## Lifecycle rules [#lifecycle-rules]

Lifecycle rules delete objects automatically. Select **Add rule** and set:

* **Applies to**: objects whose key starts with this, for example `logs/`. Empty means the whole bucket.
* **Delete objects after (days)**, counted from upload.
* **Delete old versions after (days)**, counted from when a version was replaced. Only applies with
  versioning on.
* **Abort unfinished uploads after (days)**, which frees space held by uploads that never completed.

Select **Save**. Without rules, objects are kept until you delete them.

## CORS [#cors]

CORS lets web pages on other sites read or upload to the bucket from the browser. Select **Add rule** and
set **Allowed origins** (for example `https://app.example.com`, or `*` for any site), **Allowed
methods**, **Allowed headers**, **Exposed headers** and how long browsers may **Cache preflight
(seconds)**. Then **Save**.

## Tags [#tags]

Add up to 50 key and value labels to the bucket, for example a team or cost center, and select **Save
tags**.

## Project [#project]

Pick a project under **Move to project** and select **Move** to group the bucket's costs on invoices.

## Delete the bucket [#delete-the-bucket]

**Delete bucket** deletes the bucket and everything in it. Type the bucket's name to confirm.

<Callout type="warn">
  Deleting a bucket deletes every object and version in it. This can't be undone.
</Callout>

Big buckets take a while to empty; the bucket shows **Deleting** until it's gone.
