# Use NFS storage

> Add shared NFS storage to your cluster, where it mounts, and how billing and expiry work.

NFS shared storage is an optional filesystem shared across all nodes in your cluster — useful for datasets, checkpoints, and anything you want available on every node.

## Why use it

A node's boot disk can be lost if the node is rebooted or relocated due to a hardware fault. Keep important data — datasets and checkpoints — on NFS instead.

## Capacity

NFS shared storage is optional. Let us know if you need it when you [request your cluster](/vm-clusters/order), and we'll size it to your workload.

## Mounting

NFS is mounted at `/data` on every node by default. You can re-mount or symlink it elsewhere as you like.

<Warning>
  When your contract expires, both the boot disk and NFS are deleted immediately. There is no grace period and no recovery. Back up anything important before the expiry date — see [Data retention and expiry](/vm-clusters/data-retention).
