# Persistent Storage

> A guide how to use persistent storage in Coolify.

You could add persistent storage to your resources, so you can preserve your data between deployments.

This persistent storage could be different in different types of Destinations.

## Docker Engine

If you are using Docker Engine, persistent storage could be a `volume` or a `bind mount` (a file/directory from the host system - your server).

### Volume

To create a volume, you need to define:

* `Name` of the volume.
* `Destination Path` where the volume will be mounted inside the container.

<Warning>
  The base directory inside the container is `/app`. So if you need to store
  your files under `storage` directory, you need to define `/app/storage` as the
  destination path.
</Warning>

<Tip>
  To prevent storage overlapping between resources, Coolify automatically adds
  the resource's UUID to the volume name.
</Tip>

### Bind Mount

To create a bind mount, you need to define:

* `Name` of the volume, which will be used as a reference.
* `Source Path` from the host system. **No docker volume created in this case.**
* `Destination Path` where the volume will be mounted inside the container.

<Warning>
  The base directory inside the container is `/app`. So if you need to store
  your files under `storage` directory, you need to define `/app/storage` as the
  destination path.
</Warning>

<Warning>
  Share file between more than one container? **NOT RECOMMENDED.**

  If you mount the same file to more than one container, you will need to make sure that the proper file locking mechanism is implemented in your resources.
