NexentaStor vs Synology Active Backup for SaaS

NexentaStor is software-defined storage for enterprise applications, combining file services over NFS and SMB with block services over Fibre Channel and iSCSI. It is presented for databases, enterprise NAS, private cloud, virtual workloads, backup, and archives, and can scale from terabytes to petabytes. It runs on bare-metal hardware or as a virtual storage appliance in private-cloud and hyper-converged environments. Its perpetual license includes inline data reduction, unlimited snapshots, long-distance replication, and NexentaFusion management. Administrators can also use a VMware vCenter plugin or a self-documenting REST API. Named integrations or certifications include VMware, Microsoft, OpenStack, Commvault, Veeam, and NetBackup. Nexenta describes SMB 3 encryption and Windows-style access control lists for file storage, and a checksummed, self-healing filesystem for backup. Enterprise Edition includes scheduled replication for recovery point objectives of 15 minutes or longer; continuous replication requires an extra license. Pricing is on request, with a 45-day trial available after registration.

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.
