What it is
Rockstor is an open-source network attached storage and private cloud storage system based on Linux and BTRFS, managed through a web interface. It supports storage pools, user management, on-demand and scheduled copy-on-write snapshots, and online capacity scaling. File sharing is available over NFS, Samba, SFTP, and AFP for Linux, Mac, Windows, and mobile devices. Listed BTRFS features include checksums, compression, and bitrot protection; Rockstor also supports asynchronous replication. Backup options include Rsync, Apple Time Machine, and Windows Backup. A customizable resource dashboard and SNMP provide monitoring, while Docker-based Rock-ons add apps for VPN, cloud storage, syncing, and media streaming. Installer profiles include openSUSE Leap 16.0, Tumbleweed, and Slowroll targets; Tumbleweed and Slowroll are described as experimental during the 5.5 testing phase. The Stable Updates subscription is requested but not required. The Raspberry Pi 5 profile is experimental, and setup cannot proceed on its jeOS base image through zypper because that image uses ext4 rather than BTRFS. Support is community based through the Rockstor forum.
