DSM 7.2 by Synology: Advancements in Immutable Storage, Full-Volume Encryption, and Beyond


May 21, 2023

Synology's DSM 7.2 offers innovative enhancements to address IT challenges and provide organizations with improved data management capabilities, including immutable storage and backup, full-volume encryption, increased performance and efficiency, enhanced access controls, and better management options.

  • License-free immutable storage and backup
  • Full-volume encryption
  • Increased performance and efficiency


Synology, a leading provider of network-attached storage (NAS) solutions, has recently announced the release of DSM 7.2. This latest update offers a range of innovative enhancements designed to address IT challenges and provide organizations with the tools they need to manage their data with confidence and ease.

One of the key features introduced in DSM 7.2 is license-free immutable storage and backup. This feature includes WriteOnce shared folders and Immutable Snapshots, which leverage write once read many (WORM) technology to create an unalterable copy of data. This is particularly important for industries such as healthcare, finance, and government that must comply with strict data retention policies.

Another notable enhancement is the introduction of full-volume encryption. This feature encrypts data at rest, including shared folders, LUNs, and package data, ensuring data privacy and security in the event of a security breach or theft. Full-Volume Encryption provides up to a 48% writing performance boost compared to applying Shared Folder Encryption to all eligible data stored on a volume.

DSM 7.2 also brings increased performance and efficiency to Synology systems. It adds support for M.2 NVMe SSD storage volumes on more systems, allowing for more flexible use of built-in M.2 NVMe slots. SSD deduplication has also been improved with the implementation of inline zero-block removal, resulting in up to 25% faster deduplication times.

In terms of access controls, DSM 7.2 introduces adaptive multi-factor authentication, which assesses various contextual factors to determine whether additional verification is needed. This provides a seamless approach to security and enhances overall data protection. Security measures are further enhanced with the implementation of Auto Block for connections through SMB and QuickConnect, protecting against brute force attacks.

DSM 7.2 also includes better management features such as storage capacity forecasting, which helps IT administrators and managed service providers anticipate future storage needs. Additionally, improvements have been made to DSM system notifications, with more flexible settings and added support for Microsoft Teams and LINE notifications.

Furthermore, DSM 7.2 brings ecosystem-wide improvements, including enhancements to applications and services such as Hybrid Share, Container Manager (formerly Docker), SSO Server, and SSO Client.

Synology DSM 7.2 is now available for all customers worldwide. To learn more about the latest features and enhancements, visit Synology’s website.

Technology Explained


NAS: Network Attached Storage (NAS) is a specialized storage device or server that provides centralized data storage and access over a network, usually using Ethernet connections. NAS systems are designed to offer a convenient and efficient way to store and share files among multiple users or devices within a home or office environment. Unlike traditional storage solutions, NAS devices operate independently and have their own operating systems and management interfaces. They are characterized by easy setup and configuration, making them accessible even to users with limited technical expertise. NAS devices can offer various features, including data redundancy through RAID configurations, remote access over the internet, automatic backup, media streaming, and even application hosting in some advanced models. As a versatile and user-friendly storage solution, NAS has become a popular choice for both personal and small business use.


SSD: A Solid State Drive (SSD) is a modern data storage device that employs flash memory technology to store data electronically. Unlike traditional hard disk drives (HDDs), SSDs have no moving parts, resulting in significantly faster read and write speeds. This leads to quicker boot times, faster application loading, and smoother overall system performance. SSDs are known for their durability, shock resistance, and energy efficiency, making them ideal for laptops, ultrabooks, and other portable devices. They come in various form factors, including 2.5-inch, M.2, and PCIe cards, and are favored for their reliability, quiet operation, and reduced heat generation
