### What are the current limitations of Network File Storage?

Network File Storage has its own set of limitations. For more information, see [<mark style="color:blue;">Technical Specifications and Limitations</mark>](https://docs.ionos.com/cloud/backup-and-storage/network-file-storage/overview/tech-specification-limitation).

### What are the benefits of the NFSv4.2 protocol compared to NFSv3?

Currently, IONOS Cloud supports **NFSv4.2**, which is the latest version of the NFS protocol for Network File Storage. It allows standard Linux users to read and write directly to storage, scaling performance linearly for both IOPS and throughput, maximizing the limits of storage, and network infrastructures. Some of its benefits are as follows:

* Reduced protocol overhead with compound operations and caching.
* Efficient file operations with minimal server interaction.
* Enhanced performance with multiple parallel network connections.
* Live data movement without interruption.
* Detailed file-level access and performance telemetry.
