DPlaneOS vs Synology Active Backup for SaaS

DPlaneOS is a ZFS-first storage operating system for homelab and small-office NAS deployments. It manages pools, datasets, snapshots, replication, encryption, quotas, S.M.A.R.T. and POSIX ACLs, with sharing through SMB, NFS, iSCSI and NVMe-oF. It can manage Docker and Compose stacks, ZFS-clone sandboxes, atomic updates with rollback, and an in-browser terminal. Its architecture combines a Go daemon, PostgreSQL state, a React interface and a NixOS appliance. Identity options include local users, LDAP or Active Directory, OIDC SSO, TOTP 2FA and API tokens. Cloud synchronization supports S3, Backblaze B2, Google Drive, Azure, Dropbox and rclone-compatible targets. Prometheus/OpenMetrics exposes storage and system metrics. Optional high availability is off by default; several HA configurations and NVMe-oF over TCP are marked experimental. Installation supports x86_64 and aarch64, including Raspberry Pi 5, with offline ISOs. The free Community Edition is licensed under AGPLv3. Minimum hardware is a 64-bit CPU and 8 GB RAM; 16 GB is recommended. One person maintains the project, which offers no vendor support.

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.
