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

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
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
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.
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.
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.
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)
Notify the right person or team
Directly integrate DSM notifications into your Microsoft Teams channels or LINE groups. Combine with rule-based delivery to ensure the right message is delivered to the responsible team.

Requires compatible Synology SNV3400/3500 Series NVMe SSDs.
Tested with data from 32 VMs configured as servers, totaling 1.52 TB, and 12 Synology SATA SSDs.
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.
