The record

Product: Rockstor is a Linux and BTRFS based network attached storage and private cloud storage solution managed through a web interface.
Snapshots and scaling: It supports on-demand and scheduled copy-on-write share snapshots and online capacity scaling.
File sharing: Its web interface manages file sharing over NFS, Samba, SFTP and AFP.
Data protection: Listed BTRFS features include bitrot protection, checksums and compression, and Rockstor supports asynchronous replication.
Rock-ons: Rock-ons are Docker based applications for functions including VPN, cloud storage, syncing and media streaming.
Backup and monitoring: The product overview lists Rsync, Apple Time Machine and Windows Backup, plus a customizable resource monitoring dashboard and SNMP.
Supported client devices: The product overview says files can be shared with Linux, Mac, Windows and mobile devices.
Current update subscription: The Stable Updates subscription tier is retained, but the project says it is requested rather than required.
Testing status: Rockstor's May 2026 announcement describes Tumbleweed and Slowroll targets as experimental during the 5.5 testing phase.
Installer formats: The repository says x86_64 installers are ISO images, while Raspberry Pi 4 and 5 installers are raw disk images.
Root disk encryption: The installer configuration offers optional LUKS2 root disk encryption using PBKDF2.
Pi 5 limitation: As of May 2026, the repository says Rockstor setup cannot proceed on the Pi 5 jeOS base image through zypper because that image uses ext4 rather than BTRFS.
Community support: The installer repository directs users to the Rockstor forum for assistance and describes support as community based.
Maker: The installer configuration names The Rockstor Project as the image author.
