OSNEXUS QuantaStor vs Synology Active Backup for SaaS

OSNEXUS QuantaStor manages file, block and object storage in a software-defined platform. Built on Ceph and OpenZFS, it can scale up or out while managing storage across one grid. Administrators can configure it through a web interface designed for IT generalists, or manage and automate Storage Grid servers with CLI tools and REST APIs. QuantaStor is available as ISO installation media for bare metal or virtual machines, and as a VMware OVA appliance. Its Cloud Integration SDK supports automated provisioning, storage-cloud management and auditing through RESTful APIs. OSNEXUS describes data protection in transit and at rest. For Ceph users, listed security features include AES-256 encryption, S3 Object Lock, MFA and RBAC; the Ceph page also lists alerts through email, Slack and SNMP, plus hardware monitoring. The free Community Edition is limited to 80TB raw capacity and four servers per grid, for non-commercial, educational and testing use. The Trial Edition is free for 45 days, with 256TB raw capacity and Enterprise Edition features unlocked.

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.
