## Persistent storage
## Using a Volume for storage
The container file system only lives as long as the container does, so when a container crashes and restarts, changes to the filesystem will be lost and the container will restart from a clean slate. To access more-persistent storage, outside the container file system, you need a [*volume*](/docs/user-guide/volumes). This is especially important to stateful applications, such as key-value stores and databases.
The container file system only lives as long as the container does, so when a container crashes and restarts, changes to the filesystem will be lost and the container will restart from a clean slate. For more consistent storage that lasts for the life of a Pod, you need a [*volume*](/docs/user-guide/volumes). This is especially important to stateful applications, such as key-value stores and databases.
For example, [Redis](http://redis.io/) is a key-value cache and store, which we use in the [guestbook](https://github.com/kubernetes/kubernetes/tree/{{page.githubbranch}}/examples/guestbook/) and other examples. We can add a volume to it to store persistent data as follows:
