Rockstor vs Synology Active Backup for SaaS

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.

Synology Active Backup for SaaS backs up Microsoft 365 and Google Workspace data to Synology NAS servers for recovery after data loss or service downtime. Microsoft 365 coverage includes OneDrive for Business, SharePoint Online, Exchange Online, and Teams. Google Workspace coverage includes Drive, Gmail, Contacts, and Calendar, including shared drives, labels, and attachments. Microsoft 365 backups can run continuously, manually, or on a schedule; continuous intervals adjust from one to ten minutes based on detected API request rates. Both services support file versioning, and Google Workspace versions can be retained for a chosen period or kept in full. The Microsoft 365 Recovery Portal lets administrators and employees restore or export backed-up data, with self-service access dependent on configuration. The product is a free add-on for a compatible Synology NAS, with unlimited accounts subject to NAS storage capacity. Active Backup for Microsoft 365 requires DSM 6.1-15217 or later. Deduplication requires an x64 NAS using Btrfs, and neither service supports secondary backups. Google Workspace setup requires configuring the Drive SDK API and creating a service key.
