DiskStation Manager 7.2

Immutable storage and backup, fast full-volume encryption, and stricter access controls. The new DSM lets you turn your system into a true data fortress.

DiskStation Manager 7.2

Data resiliency and protection

Write once, store forever

Technically enforce data retention policies with WriteOnce shared folders, which are locked down against modification or deletion. Protect folders for a defined period or disable changes forever.1

Compliance Mode
Enterprise Mode
Tamper-proof Clock
Grace Period
Appendable Mode
Admin-only Overwrite

Encrypt entire volumes

Full Volume Encryption allows protecting Shared Folders, LUNs, and package data against physical theft of system and drives, while boosting speed, security, and convenience.3 Learn more

Checkmate, ransomware

New Immutable Snapshots in Snapshot Replication safely store immutable copies of your data to defend against compromised administrator credentials.1

  • Shared Folders2
  • LUNs

Performance and efficiency

Turbocharge VM performance

M.2 NVMe storage volumes4 are now supported on more systems. Choose between speeding up larger volumes with SSD cache or creating nimble all-flash storage volumes.

Now also available on:

  • 22 Series: DS1522+
  • 21 Series: DS1621+, DS1821+, DS1621xs+

Protect more data, faster

New support for block-level full-system backups in Hyper Backup significantly speeds up backing up of large quantities of data.6

Over2X fasterFull system vs individual tasks

Dispense with duplicates

Inline zero-block removal speeds up deduplication by cutting post-process dedupe times, while maintaining I/O performance and reducing writes to SSDs. Learn more

Up to 25% speed boost5
Write reduction

Access controls

Adaptive login protection

Two-factor authentication (2FA) is often not enabled. Adaptive Multi-Factor Authentication (AMFA) now demands confirmation when DSM admin accounts are accessed from untrusted external connections.

1. AMFA triggers for:
Unrecognized devices?
WAN connections
Password-only admin accounts***
2. Login confirmation through:
Secure SignIn
DS finder

New defenses against attacks

An expanded Auto Block in DSM 7.2 covers SMB connections, significantly reducing the possibility of brute-force attacks succeeding against weaker credentials.

QuickConnect servers now globally ban IP addresses after several failed authentication attempts.

New defenses against attacks

One account to take you anywhere

Expanded SSO Server and SSO client protocol support in DSM 7.2 enables convenient single-account access no matter what provider is used.

SSO client
Synology SSO

Transparent management

Direct notifications more effectively

More configuration options help finetune notification rules to ensure critical messages get delivered.

  • Unlimited email recipients per rule
  • Set custom delivery channels per rule (email, push service, webhook)

  1. WriteOnce and Immutable Snapshots availability: https://sy.to/wormmodels.

  2. Encrypted Shared Folders and Hybrid Share Folders currently not supported.

  3. Volume encryption availability: https://sy.to/encryptedvolkb

  4. Requires compatible Synology SNV3400/3500 Series NVMe SSDs.

  5. Tested with data from 32 VMs configured as servers, totaling 1.52 TB, and 12 Synology SATA SSDs.

  6. Comparing full system backup using Hyper Backup against creating separate file, LUN, and package backup tasks. Tested on DS923+ with 5.3TB of data (95% <4MB), comparing initial backup speeds. Subsequent backup speed improvements may be higher.
