Synology DS423+ NAS Rack (8U) Ethernet LAN Black J4125

A capable all-around performer
The versatile DS423+ can serve as a central storage device as well as a multimedia hub.

Btrfs: advanced file system for data protection
The Synology DiskStation Manager (DSM) operating system that powers DS423+ uses the advanced Btrfs file system, which safeguards your data against corruption and allows for the reversal of any unintended or malicious changes through the use of snapshot technology.

A private cloud for all your devices
Store, sync, access, and share data from any device, wherever you are. Work seamlessly between different platforms and devices, and access your files through mobile apps, desktop clients, and a browser-based interface. Quickly and easily roll back files in case of accidental deletion, mistakes, malware, etc., with the versioning feature.

Keep your photos organized
Efficiently back up and organize photos and videos with management tools for amateurs and professionals. Automatically organize your content into albums and create secure share links for family, friends, or clients.

Effortlessly keep multiple Synology NAS in sync
Collaborate with minimal downtime using site-to-site file syncing, which can be configured to automatically synchronize individual files or folders between Synology devices, allowing seamless file access.

Share data with the power of the cloud
Reduce your on-site storage footprint and benefit from data center network speeds with hybrid cloud technology. The optional Hybrid Share service provides efficiently storage of cold data in the cloud, while keeping frequently accessed files cached locally on your DS423+ and accessible at LAN speeds.

Back up PCs, smartphones, cloud apps, and more
Consolidate and automate backup tasks for PCs, file servers, VMs, SaaS applications, and more with Active Backup Suite. Administer device backups remotely through a centralized 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. Allow users to easily restore previous versions of files unassisted, quickly recover VMs, and copy snapshots to another server to benefit from rapid storage failover.

Synology Surveillance Station
Protecting your business has never been easier, with centralized 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 C2 cloud. End-to-end encryption protects streams against unauthorized access while low latency recording lets you review the crucial last few seconds before the recording server was lost.
