# Persistent Storage

> Share persistent storage across multiple containers and replicas

Persistent Storage preserves your data even when a container is stopped or restarted. Within a Project, a single volume can be shared across multiple containers or Replicas.

## What You Can Do with Persistent Storage

Persistent Storage provides flexible data management across your deployments.

* **Support Autoscaling**: Attach the same volume to deployments using Autoscaling and multiple Replicas.
* **Create or Reuse Volumes**: Create a new volume or attach an existing one during container deployment.
* **Share Across Deployments**: Attach the same volume to multiple deployments. When selecting a volume, AirCloud also shows which deployments are currently using it.
* **Modify While Stopped**: Enable, disable, or replace an attached volume while the container is in the **Pending** state.

## Usage

### Create a New Volume

You can create and attach a new Persistent Storage volume during container deployment. Each volume supports up to **300 GB** of storage.

### Attach an Existing Volume

You can attach a volume that is already in use by another container, allowing multiple deployments to share the same storage.

When selecting a volume, AirCloud displays the deployments that are currently using it.

<Tip>
  **Multiple Replicas within the same deployment can share a single Persistent Storage volume.** This works seamlessly with Autoscaling-enabled deployments.

### Modify a Volume While Stopped

You can modify Persistent Storage settings only when the container is in the **Pending (Stopped)** state.

You can:

* **Disable** or **re-enable** the attached volume.
* **Replace** the attached volume with another one.

Changes take effect the next time the container is started.
