Rockstor is a specialist CentOS-based Linux distribution designed for Network Attached Storage (NAS) and private cloud storage solutions. It is based on popular open-source technologies, such as the Btrfs file system and Docker for automating the deployment of applications inside software containers. In addition to standard NAS features like file sharing via NFS, Samba, SFTP and AFP, advanced features such as online volume management, CoW Snapshots, asynchronous replication, compression, and bitrot protection are also supported. Rockstor provides additional applications, including ownCloud, Syncthing, OpenVPN and Plex. These applications (called “Rock-ons”) are powered by a Docker-based application hosting framework. The Rockstor user interface, written in JavaScript, makes it simple to manage the server from within a web browser.
