Backup data in multiple ways

Synology DS916+ can serve as a centralized backup target. Whether you are a Windows or Mac user, you can back up everything on your computer directly to Synology NAS using Cloud Station Backup. Whenever you modify a file, the changes are backed up to DS916+ automatically. Mac users also enjoy native Apple® Time Machine support. You can also back up data from your DS916+ to another DiskStation, rsync servers, external drives, or even Amazon® S3, Glacier cloud service, Microsoft Azure, SFR, and hicloud. Synology Hyper Backup allows you to schedule backup tasks and restore the server to any particular point in time, while minimizing storage consumption and processing time by saving only the specific data block that has been changed between versions. Learn more

Next-generation data protection and integrity

When dealing with large-scale data storage, businesses require a solution that offers reliable backup and prevents file corruption. With support for the next-generation Btrfs file system, DS916+ ensures information is stored with a high level of data integrity, while providing flexible and efficient data protection tools. See the white paper for more technical details regarding Btrfs and data protection.
Learn more about the benefits of using Btrfs

Fast and efficient snapshots

Snapshots preserve the history of a shared folder allowing you to save up to 1024 backup copies for point-in-time recovery. Snapshots can be automatically captured up to every 5 minutes, without noticeably impacting system performance.


Metadata mirroring and survivability

Btrfs file system stores two copies of critical metadata on a volume, improving the availability and ensuring the integrity of your file system.


Corruption detection and correction

Btrfs generates checksums for data and metadata, and then verifies the checksums during each read process to ensure the integrity of the filesystem and files. If the file system discovers a mismatch, metadata will be repaired to keep file system consistent. In the meantime, corrupted files will be reported and logged.


Customizable quotas for shared folders

With Btrfs, you can specify a storage limit for each shared folder, making it possible to precisely control space consumption when multiple teams or departments save files on the same Synology NAS server.

Ultimate file center

File Station is a fast and secure feature for sharing and managing your files stored on DS916+. Just drag-n-drop and upload data from Mac or PC. Advanced filters make it easy to search for documents, photos, or videos. With built-in FTP or email clients, DS916+ lets you organize and share files through an advanced web application effortlessly. You can even share files and folders with others by simply sending a link. Files can be reached on mobile devices via the companion mobile app DS file. HTTPS, SSL/TLS encryption, and link expiry dates also ensure file sharing over the Internet is highly secure. Learn more

Seamless storage solution for virtualization environments

DS916+ provides seamless storage solutions for virtualization environments, including VMware, Citrix, and Microsoft Hyper-V. With VMware vSphere® & VAAI integration, DS916+ helps offload specific storage operations and optimizes computation power in VMware environments. Windows ODX support speeds up data manipulation as the data transfer is offloaded. iSCSI also lets SMB users consolidate storage into data center storage arrays while providing hosts with the illusion of locally-attached disks. Learn more

Secure your data

DS916+ offers advanced security measures to protect you from potential security holes. Security Advisor analyzes system settings, password strength, network preferences and removes any possible malware. AppArmor blocks malicious programs from accessing unauthorized system resources. You can also customize the trust level in Package Center to avoid installing packages from untrusted sources, safeguarding your NAS from unknown or tampered files. In addition, DS916+ provides other security add-ons, such as AES encryption, 2-Step verification, IP block & allow list, Antivirus packages, firewall, and DoS attack prevention. Learn more
