Btrfs File System

Evolvement of the next-generation file system

Btrfs file system in DSM 6.1 extends its model coverage with more advanced functionality. Learn more about Btrfs file system

File self-healing

Btrfs file system is able to auto-detect corrupted files (silent data corruption) with mirrored metadata, and recover broken data using the supported RAID volumes, which include RAID 1, 5, 6, 10, F1, and SHR.

Instant SMB server-side copy

The standard SMB server-side copy requires processing time, even when copying data to the same volume. With the help of Btrfs fast-clone technology, you can achieve instant file copy over SMB on your computer if the source and destination are both on the same Btrfs volume.

Extended Btrfs coverage

DSM 6.1 brings Btrfs file system to more Synology NAS models. Enjoy the powerful features of the next-generation file system. Learn more about Btrfs applied models

Shared Folder Encryption

Flexible yet secure data protection

Encrypt pre-existing shared folders, including the homes folder, whenever you need. With Key Manager, you can now use a USB storage device as a physical key to mount encrypted shared folders automatically without having to memorize all the encryption keys.

Active Directory Server

A comprehensive tool for user and resource management

Transform your Synology NAS to serve as a domain controller and streamline IT maintenance by creating policies to automatically install certain software or system updates on all of your employees' computers without the need to visit each one individually. Watch the video tutorial

USB Copy 2.0

Copy data between Synology NAS and USB/SD devices

With a few simple settings in USB Copy, files and folders can be automatically copied from your Synology NAS to an attached USB/SD device or vice versa. Once a USB/SD device is connected to your NAS, data can be immediately transferred and backed up. Learn more about USB Copy 2.0

Resource Monitor

View resource usage at a glance

Generate a more detailed report of running applications and information regarding their running time and hardware utilization. Performance Alarm2 is a new notification tool that sends warnings based on resource utilization to help IT administrators take appropriate measures on time.

Snapshot Replication

Replication, backup, and recovery for data availability

Snapshot Replication in DSM 6.1 introduces encrypted shared folder replication for data-sensitive businesses, local replication for an additional layer of protection, and automatic pause/resume during replication to efficiently optimize network bandwidth. Learn more about Snapshot Replication

SMI-S Provider

Manage storage devices at one single entry-point

A brand new package optimized with Microsoft's System Center Virtual Machine Manager (SCVMM), allowing an IT administrator to manage multiple Synology NAS servers as storage nodes via SCVMM's centralized user interface. See here for applied models.

Time Machine

Enjoy the flexible backup solution on the latest macOS

You can now designate multiple shared folders with specific usage quotas (available on Btrfs volumes) to use as backup destinations, preventing unauthorized access or overcapacity. In addition, SMB is now supported on Time Machine on macOS Sierra.

Storage Manager with Seagate IronWolfTM Health Management

Effectively monitor the health status of your IronWolf drives on Synology NAS

Storage Manager is now integrated with Seagate’s IronWolf Health Management, providing live drive health monitoring and suggested actions. The Iron Health Management aims to minimize impact to drive health and reduce probability of catastrophic data loss due to extreme operational and environmental factors.3

More features

  • Extended RAID F1 support: RAID F1 is now available on more Synology NAS models to take advantage of the new RAID type designed for all flash storage.
  • SMB 4.4 upgrade: Supports sparse files, saving space while archiving image files of virtual machines.4
  • Nested group on Directory Server: Nested group architecture is now supported in Directory Server, allowing a more intuitive and easier way for user management.
  • Offline authentication on Radius Server: The new offline authentication leverages the cache mechanism for convenient login even when the Active Directory domain server is offline temporarily.
  • Migration from SHR-1 to SHR-2: Performing migration from SHR-1 (one-disk redundancy) to SHR-2 (two-disk redundancy) allows greater flexibility of storage expansion and better data protection.
  • DSM code sign: Much like your phone is able to block applications from untrusted sources, your Synology NAS can also block DSM patches that don't match the right sign code, adding an extra layer of security to your stored data.
  • Package Center auto-repair: If some packages become broken after a DSM upgrade and require an update, DSM can now automatically fix them during the upgrade to ensure the entire process is smooth.
