What Rockstor is
Rockstor is an open-source Linux and BTRFS system for network attached storage and private cloud storage, managed through a web interface. It supports storage pools, user management, scheduled or on-demand copy-on-write share snapshots, and online capacity scaling. Files can be shared over NFS, Samba, SFTP, and AFP with Linux, Mac, Windows, and mobile devices. Listed BTRFS features include checksums, compression, and bitrot protection; Rockstor also supports asynchronous replication between systems. Backup options include Rsync, Apple Time Machine, and Windows Backup. A customizable resource dashboard and SNMP cover monitoring, while Docker-based Rock-ons add apps for functions such as VPN, cloud storage, syncing, and media streaming. Installer profiles include openSUSE Leap 16.0 and Tumbleweed, along with Slowroll and several Raspberry Pi and ARM targets. The project describes Tumbleweed and Slowroll as experimental during the 5.5 testing phase. The Stable Updates subscription is available but requested rather than required.
