# Update Cluster

You can append a cluster, or update the content of an existing cluster within your Network File Storage using the `PUT` API request.

## Endpoints

Use a [<mark style="color:blue;">region-specific endpoint</mark>](https://docs.ionos.com/sections-test/guides/storage-and-backup/network-file-storage/api-how-tos/..#endpoints) to update a cluster: `https://nfs.{region}.ionos.com/clusters/{clusterId}`
