This device features Windows Server IoT 2019 and integrates seamlessly in a Windows-based environment as well as various Microsoft services such as Azure and OneDrive. It offers flexibility to be used as you see fit, such as acting as a central backup hub for all your data needs (including but not limited to being an on-premises cloud backup to or from any Windows-compatible cloud service), being set up as a surveillance server for security cameras, or serving as a subscription-free BDR appliance.

You can make full use of commonly-used network environments and standard management software you already have for your infrastructure.

Windows Server IoT NAS as a Central Backup Hub

This system 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. The 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, and a surveillance server for a network of security cameras.

Strengthen Your Backup and Disaster Recovery 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.
