Ultimate Backup Solution

RS820+/RS820RP+ integrates various backup applications to safeguard your important data on any devices with an intuitive user interface and durable storage technologies.

• Workstation/Server/Virtual Machine/SaaS backup: Active Backup for Business centralizes backup tasks for virtual machines, Windows PC, servers, and rsync/SMB file servers and offers various recovery options to ensure lowest RTO. Active Backup for Office 365/G Suite is an on-premises backup solution for public clouds with a centralized dashboard, optimizing storage efficiency through the single instancing and block-level deduplication technology.
• NAS backup: Hyper Backup comprehensively backs up your data to a local shared folder, an external device, another Synology NAS, an rsync server, or Synology public cloud service, Synology C2 Backup5, to ensure data safety and availability can be achieved when a disaster happens
• Computer backup: Synology Drive Client backs up your Windows, Mac, and Linux desktop devices to safeguard important computer files. RS820+/RS820RP+ is also compatible with Time Machine, allowing you to effortlessly back up your Mac to Synology NAS.

Btrfs: Next Generation Storage Efficiency

RS820+/RS820RP+ introduces Btrfs file system, bringing the most advanced storage technologies to meet the management needs of modern business:

• Advanced snapshot technology provides schedulable and near-instantaneous data protection of share folders and iSCSI LUNs.
• File and folder level data restoration brings great convenience and saves time for users who wish to restore only a specific file or folder.
• Flexible Shared Folder and User Quota System provide comprehensive quota control on all user accounts and shared folders.
• File self-healing allows Btrfs file system to auto-detect corrupted files with mirrored metadata, and to recover broken data using the supported RAID type of volumes, including RAID1, 5, 6, and 10.
