Nasuni leverages the resources of the cloud to deliver unlimited file storage with built-in file protection, radically simplifying file storage and protection for business. We believe that the cloud is the future of both file storage and protection. Mega storage systems have huge advantages of scale over private data centers, and the redundancy of their architecture provides protection for files without the opacity and hassles of tape. When several mega clouds recently became available to developers and the public, our only question was, how we can deliver all that potential to business with the least upheaval and the most added value? The clear advantages of the cloud were easy-storage capacity would be unlimited, files would be protected with redundancy, IT managers would no longer have to buy or maintain hardware, and because the files would be stored offsite, they'd be safe in a disaster. But for storing files offsite to be a practical solution, you'd have to be able to access your working set at local speeds. The redundant protection of the cloud would only be truly useful to the active life of your data center if the protected files in the cloud were kept up-to-date and restores were easy and fast. And any solution would have to preserve everything that NAS still does best. And so we developed the Nasuni Filer, a NAS-like downloadable virtual file server that stores all your files with the cloud provider of your choice, while keeping copies of your working set cached to your local storage infrastructure, where they can be accessed as quickly as any local file. Snapshots capture the entire system frequently and send the changes to the cloud. You can easily view and restore any past version of a file, directory or file system, and, during a recovery, high-priority files are available for use immediately. The Nasuni Filer looks much like a NAS, and uses familiar protocols for serving out files, so the transition between your current file environment and a cloud-provisioned one is smooth.
