The Synology DS224+ is a compact 2-Bay NAS solution designed to bring centralised data management to small organisations and teams. Synology DiskStation Manager (DSM) supports creating a private cloud to make working together better for everyone. It features tools to manage, share, and protect files and photos, back up devices and data, and manage surveillance recordings.
Key Features
- Capacity
Un-populated two (2) bay network attached NAS storage device. - Centralised Data Storage
Consolidate all your data for complete data ownership and multi-platform access. - Sharing and Syncing Across Systems
Access, share, and sync data across different systems and devices using intuitive controls. - Powerful Backup and Restoration
Back up and restore critical devices and data using a host of intuitive backup tools. - Built-in Data Management Tools
Leverage built-in file and photo management, data protection, and video surveillance solutions.
Keep your data on-site
- Consolidate and safeguard
Protect all your data with integrated security features and centralised access. - Manage important data
Share, back up, and access files, photos, surveillance video, and more. - Minimise energy impact
15 watts under full operation keeps operating costs low.
Simply faster
The DS224+ is faster at indexing files in Synology Drive and Synology Photos and more capable of running demanding web applications compared to previous-generation systems.
Store, share, and protect
Manage all your documents, images, and other files, back up applications and devices, and protect your property with professional video surveillance.
Private cloud for data sharing
- Hybrid work in the private cloud
Store, sync, access, and share data from any device, wherever you are. Work together seamlessly across different platforms, accessing files through mobile apps, desktop clients, or a browser-based interface. Quickly and easily roll back files in case of unwanted deletion or modification thanks to smart versioning. - Keep your photos organised
Effortlessly back up and organise photos, videos, and other visual assets using intuitive management tools. Automatically organise your content into albums and create secure share links for stakeholders and teammates. - Synchronise data between sites
Work together with minimal slowdown using site-to-site file syncing, which can be configured to automatically synchronise individual files or folders between Synology devices, allowing seamless file access from local devices. - Manage data with the power of the cloud
Reduce your on-site storage footprint and benefit from data centre network speeds with hybrid cloud technology. Synology Hybrid Share adds automatic cloud tiering, keeping the bulk of data in the cloud, while caching frequently accessed files cached locally on your DS224+ for fast access at LAN speeds.
Multi-layered backup
- Back up workstations, smartphones, cloud apps, and more
Consolidate and automate backup tasks for workstations, file servers, VMs, SaaS applications, and more with Active Backup Suite. Administer device backups remotely through a centralised portal and quickly restore specific files or entire devices to keep your business up and running. Take advantage of built-in remote backup solutions designed to protect your data with seamless 3-2-1 backup configurations. - Perform full Synology system backups
Protect all data, applications, and configurations on your Synology systems with comprehensive scheduled backups to local and remote servers, external drives, or cloud storage destinations including Synology C2 Storage. - Protect folders and LUNs with snapshots
Configure efficient point-in-time snapshots of shared folders and LUNs at intervals as short as 5 minutes. Let users easily restore previous versions of files unassisted, quickly recover VMs, and copy snapshots to another server to benefit from rapid storage failover. Further safeguard data integrity with immutable snapshots.
Smart surveillance management
- Synology Surveillance Station
Protecting your business has never been easier, with centralised management, support for over 8,300 IP camera models, and remote monitoring and playback. Synology’s video management system provides all the tools you need for live monitoring, investigation, management, and backup. - Dual recording to the cloud
C2 Surveillance allows you to keep access to surveillance footage if your recording server is disabled by recording to your local server as well as the C2 cloud. End-to-end encryption protects streams against unauthorised access while low latency recording lets you review the crucial last few seconds before the recording server was lost.
Btrfs: advanced file system for data protection
The Synology DiskStation Manager (DSM) operating system that powers the DS224+ uses the advanced Btrfs file system, which safeguards your data against corruption and allows for the reversal of unintended or malicious changes through the use of snapshot technology.
