Windows Server-based NAS storage that are reliable and versatile - Hard Drives Included

TeraStation WS5020 Windows Server IoT Network Attached Storage devices are purpose-built as efficient data storage and backup solutions for small businesses. These devices run on the Windows Server IoT 2019 operating system, which is a binary equivalent to Windows Server 2019, and integrate seamlessly into Windows-based environments as well as with various Microsoft services such as Azure and OneDrive. This Windows Server version is only available on NAS through the OEM. The TeraStation NAS offers flexibility to be used as you see fit, such as acting as a multi-purpose file server, a central backup hub for all your files (including backing up to and from cloud services), being set up as a NVR server for security cameras, or serving as a subscription-free backup and disaster recovery (BDR) appliance.

Easy and Simple: Smooth integration with your Windows Environment

Because the TeraStation Windows Server NAS is running Windows Server IoT 2019, you can integrate the NAS seamlessly into your existing Windows environment and enjoy simple and low-cost deployment, while making full use of commonly-used network components and standard management software you already have. Cloud integration means you can scale your storage as your business needs. The TeraStation with Windows Server IoT can offer peerless flexibility as data storage and backup for your business. Active Directory support and no Client Access Licenses (CALs) required allow you to add users and devices at no additional cost. The TeraStation Network Attached Storage also supports Microsoft services such as Azure and OneDrive, as well as other Microsoft-compatible cloud services so you can effortlessly store, back up, and manage your data as you see fit.

Windows Server IoT NAS as a Central Backup Hub

The TeraStation enables simple backups from multiple sources into one central repository. The Windows Server OS offers multiple data security and backup features to make backups secure and effortless.
This multi-purpose storage device allows for:
Seamless integration with Windows-based environments
Native data deduplication and security features from OS
An on-premises backup solution to and from the cloud
A surveillance server for a network of security cameras
A subscription-free BDR appliance
Maximize your storage with Data Deduplication, Shadow Copy and seamless Azure and OneDrive integration. Utilize expansive virtual machine capabilities to create a scalable and cost-effective backup and recovery solution that you can expand as you see fit while reducing hardware overhead costs.

Strengthen Your Backup and Disaster Recovery (BDR) Plan

Disaster can strike at any minute, which is why it is essential to have a comprehensive plan for business continuity and disaster recovery (BC/DR). This device can serve as a subscription-free BDR solution, with DFS replication and Storage Replica to replicate data across servers and Shadow Copy to create image backups. You can also set up the NAS as an offline replication backup location and bypass cloud storage costs. In a pinch, you can use Hyper-V to create a virtual machine (VM) as a temporary solution, or create an archive of Azure VMs for redundancy.

10GbE Compatible: Ready for future data growth

With data volumes and file sizes growing, faster data access is more essential than ever to sustain productivity. The WS5020 NAS storage offers a native 10GbE port, so you can eliminate network bottlenecks and reduce data backup times compared to 1GbE environments. No 6A cabling in your office? No problem! The WS5020 NAS is compatible with IEEE802.3bz and it gives you faster data transfer speeds even with your CAT 5e environment.
