Sorry, this product is no longer available, contact us for the replacement.
Snap Server Guardian OS Overview:
GuardianOS is the ideal NAS platform for business. Unlike consumer NAS offerings that are optimized for MP3 and photo storage, GuardianOS is purpose-built to provide the business-grade reliability and out-of-the-box integration needed to work with today's business applications and infrastructure. Powering the SnapServer NAS line, the award-winning GuardianOS has over a decade of the proven stability, expertise and innovation you can rely on.
This flexible, cost effective platform allows you to scale seamlessly as your capacity, performance and number of SnapServers grow. Because SnapServers attach directly to the network, they install in minutes and are easily deployed without application downtime. You can consolidate systems by creating file- and block-level volumes on a single device. And centralized management combined with a comprehensive set of data protection tools reduces the time and resources required to manage your storage.
With This Product You Can...
- Sync data across SnapServers, desktop clients and mobile devices with BitTorrent® Sync
- Easily configure, manage, and monitor your SnapServer(s) from anywhere in the world
- Effortlessly move data to your SnapServer with the built-in data migration tool
