Synology DSM 7.2 NAS Software Now Officially Released

Synology DSM 7.2 brings a range of benefits and features compared to Synology DSM 7.1/7.0. It introduces immutable storage and backup through WriteOnce shared folders, enforcing data retention policies and protecting against modification or deletion. Compliance Mode features like Tamper-proof Clock, Grace Period, Appendable Mode, and Snapshots enhance data protection. Full Volume Encryption encrypts Shared Folders, LUNs, and package data, providing security and convenience with improved performance, but at the VOLUME level! Immutable Snapshots defend against ransomware by securely storing unchangeable copies of data. Turbocharged VM performance is achieved with M.2 NVMe storage volume support on select devices, enabling SSD caching or creating all-flash storage volumes. Block-level full-system backups in Hyper Backup speed up large data backups significantly. Inline zero-block removal improves deduplication efficiency while maintaining performance. Adaptive Login Protection enhances security with multi-factor authentication and confirmation for external DSM admin account access. Auto Block expands protection against brute-force attacks, and QuickConnect servers globally ban IP addresses after failed authentication attempts. Container Manager, renamed and enhanced, allows easy management of multi-container applications through the UI. Combined with improvements in Hybrid Share, coming soon, preventing file conflicts across connected Synology systems and provides detailed logging. These features make DSM 7.2 a comprehensive upgrade with robust security, performance, and management capabilities for Synology NAS users.

Earlier this month, we had Will from Spacerex on the channel and we discussed the things we liked and disliked in DSM 7.2 (based on the Release candidate made available weeks before the full release today). Here is what we thought:

What Are the Key Benefits of Synology DSM 7.2?

Synology DSM 7.2 introduces several benefits and features compared to Synology DSM 7.1/7.0. Here is a summary of the key advantages:

  1. Immutable Storage and Backup: DSM 7.2 allows you to create WriteOnce shared folders that are locked down against modification or deletion. This ensures data retention compliance and protects folders for a defined period or disables changes permanently. Compliance Mode features  Tamper-proof Clock, Grace Period, Appendable Mode, and Snapshots, further enhance data protection. Meanwhile Enterprise Mode has all of the above plus, Admin-only Overwrite when needed to give you the slightest wiggle room! There are also modifiable policies that allow temporary modification windows where appropriate.
  2. Full Volume Encryption: DSM 7.2 introduces Full Volume Encryption, which encrypts volume scale Shared Folders, LUNs, and package data to protect against physical theft. Previously you had the ability to enable individual encryption to a number of these services, but whole ‘whole volume wide’, but now your can. It improves speed, security, and convenience while achieving 48% sequential write performance compared to Shared Folder Encryption.
  3. Immutable Snapshots: The new Immutable Snapshots in Snapshot Replication feature safeguards your data against compromised administrator credentials. It securely stores immutable copies of your data, providing protection against ransomware attacks.
  4. Turbocharged VM Performance: DSM 7.2 expands M.2 NVMe storage volume support, allowing you to accelerate larger volumes with SSD cache or create nimble all-flash storage volumes. This enhances virtual machine (VM) performance. It is worth noting however that it is only available on certain models currently.
  5. Faster Block-Level Full-System Backups: Hyper Backup now supports block-level full-system backups, significantly speeding up the backup process for large quantities of data. It offers over 2X faster backups compared to individual tasks.
  6. Inline Zero-Block Removal: DSM 7.2 introduces inline zero-block removal, which speeds up deduplication by reducing post-process dedupe times. This optimization maintains I/O performance while reducing writes to SSDs.
  7. Adaptive Login Protection: To enhance security, Adaptive Multi-Factor Authentication (AMFA) is introduced in DSM 7.2. It requires confirmation for DSM admin accounts accessed from untrusted external connections. Unrecognized devices, WAN connections, and password-only admin accounts can trigger login confirmation through Secure SignIn, DS finder, or email.
  8. Enhanced Defenses against Attacks: DSM 7.2 expands Auto Block to cover SMB connections, reducing the likelihood of brute-force attacks succeeding with weaker credentials. Additionally, QuickConnect servers globally ban IP addresses after multiple failed authentication attempts.
  9. Container Manager (formerly Docker): The Container Manager has been renamed and improved in DSM 7.2. It allows users to add and manage multi-container applications using Docker Compose directly from the user interface. Updating and cleaning up containers is now more convenient. Container Manager is now also available on DS420j and DS223.
  10. Hybrid Share Improvements: DSM 7.2 introduces improvements to Hybrid Share, which offers global file locking to prevent conflicts across connected Synology systems. It prioritizes files requested at other sites for syncing to C2 Storage, and more detailed logging aids administration.

These are some of the benefits and features introduced in Synology DSM 7.2. It is important to refer to the official Synology documentation and release notes for detailed information on specific functionalities and compatibility with your Synology NAS model.

Note:

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

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

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

  • 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 backup package tasks. Tested on DS923+ with 5.3TB of data (95% <4MB), comparing initial backup speeds. Subsequent backup speed improvements may be higher.

Alternatively, you can look at the video below that outlines whether existing DSM 7.1/7.0/6.2 Users that own Value series devices (such as the DS223, DS423, DS220J and even DS120J) should upgrade:

      1. I bought the DS124… before i had the DS213j with only one 8tb drive – i do not need a raid at home, its only for fun – but i have always a backup made with HyperBackup. Restoring need something about 2-3 days for 4tb. I think this is ok! All services are running fine (smb, afp, TM, SynologyDrive, upnp etc). My dns-server-filter is running on raspberry. The complete installation spares a lot of power – Fritzbox Router+Raspberry+Nas max 23w/h . The only teardrop for the DS124 – no rubbers for the drive – the DS213j is with rubbers.

      2. I updated to DSM 7.2 from 6.2 a few days ago and wish I hadn’t. I use Linux almost exclusively and access everything via NFS. Before the update everything was fine. After the update I lost all access and had to reconfigure the NFS permissions on all shared folders. After taking care of that I found that I only had read only access to about half the files on the NAS. For reasons I honestly don’t understand the files were owned by a user that was removed during the update. After changing ownership on anything I needed read/write access to I was ok. Maybe a Windows user wouldn’t have run into these problems but from a Linux perspective the update was less than ideal. I am mostly a QNAP user (I understand and can take care of my own network security, thank you) and never had an update go as roughly as this. I am not impressed with either DSM or the hardware Synology tends to use in all but the super expensive models. I doubt I will ever buy another one of their products,

      4. This video is what convinced me to get the 223j instead of the 223. Why becuase your only using 56% of 512mb of ram and running dsm 7.2. So I couldnt justify spending 34% ($65) more for 1gb extra ram and 1 extra usb port. It just dosnt make sense when the 223j will run everything the 223 does including container manager. With that being said yes you cant run everything at once but i dont plan to anyway.

      7. Finally someone explaining why one might, or might not, move to DSM7.2 My DS218+ had the ‘does not update automatically” message and that leaves one wondering why not – is there a potential problem; will something go awry. I was concerned at the long list of “new” security and am pleased to learn that these are, or will shortly be, included in 7.1
        I think that Synology could have made the update benefits ( or not) much clearer than they have; and you did. Thanks.

      8. 7.2…I don’t want to say it CAUSED my file system to crash, but let’s just say it was running fine before I installed 7.2 (918+)…now it’s in Read-Only mode, I’m moving 20 years of data off to a TrueNAS box I had to throw together..and I’m kinda pissed about it.

      9. May I please ask where I can find and learn about info upgrading my DS918+ to the latest DSM 7.2 update?

        I’d like to know what features I’d lose and what features I’d gain. Basically is it a good idea to update my version 7.1.
        Or if its not broken then don’t fix it?

        I have found the manual download, and it is ready to update. However I have not pulled the trigger because I got a warning window to do some stuff first in case I get kicked out of my NAS box.

        Cheers

      10. DSM 7.2 = NO DISABLED ACCESSIBILITY SUPPORT — UNPLUG YOUR MOUSE AND TRY TO USE DSM 7.2

        Being blind is not the only disability! NVDA is not appropriate or useful for every disability! And indeed, makes using DSM by voice or keyboard a nightmare.

        Each and every DSM desktop function MUST have a KEYBOARD SHORTCUT/Navigation with the keyboard MUST include FEEDBACK – WHAT ICON IS SELECTED? WHAT WINDOW INPUT ITEM HAS FOCUS? What will happen if ENTER is pressed? How are controls selected by voice?

        Example 1: Try to select the PERSONAL MENU by KEYBOARD or VOICE
        Example 2: Try to select a specific Pinned Menu item (icon) by KEYBOARD or VOICE
        Example 3: Even selecting Main Menu items is a nightmare – NO FEEDBACK – can’t tell which icon is selected!
        Example 4: After entering a Control Panel item (like Network) – NO FEEDBACK – can’t tell which control item is selected.

        WCAG 2.1 guidelines: apps must be accessible to users with impairments to their mobility – like those who find it difficult to use a mouse.

      12. Here are some topics I’d be interested in… (I have a DS218+ and DS720+)
        – I’d like to cluster them or migrate to a cluster
        – sharesync get’s upset when the SSL keys change
        – My DS218+ is my main NAS but I want to fully migrate to the DS720
        – can I run OpenBSD in the VM

      13. DSM 7.x basically requires an additional RAM upgrade for the NAS to run smoothly and respond quicker. Any NAS that doesn’t have upgradable RAM could struggle with each new DSM release.

      14. Hi, has Synology corrected the vulnerability you disclosed during the beta? You said pressing the reset button allows a burglar to login as an admin and see the encrypted volume already mounted. Synology replied to you this should be corrected… is it now? Thanks.

      15. Docker is just a wrapper, Container technology is often confused and using “docker” is actually a bad practice in the industry as containers, LXC is a better term.

      16. Anyone know how to configure NFS 4.1 between Synology devices (spoiled by multipath smb)? It seems like when you mount a NFS share the server can be 4.1 but the client is limited to 4.0. Have you found a work around? (looking to multi path 4.1 for fast connections between NAS)

      17. This is a great co-operation for the video. Bring Wundertech as well next time? Also, im wondering what the point is with non-editable snapshots, if the nas is taken over (full admin control by a hacker), wont they just change the passwords for all accounts/make it non accessible?

      22. You incorect I hosted old websites on my DS718+ – thaat old websites requayed PHP 5.6 to run upgrade them for example php 7.4 not make sence becouse for me all custom screapts I must reduing again and reistall websites from begining – for me is to mach money and time process – I asked Synology support about it and they are tell me something like this: “PHP 5.6. is end of life thats why We droped PHP 5.6 on DSM 7.2 and newer versions of DSM.” – for me I not se reason to install DSM 7.2 if I know this: Upgrading to DSM 7.2 broke all web part of my homelab installation – I simply don’t have time to reinstall it again on difrent engine

      23. Excellent video. I have a DS420J, which was my first entry into NAS about 3 years ago. I was wondering if you have made a video about migrating/upgrading to new hardware? I’m guessing it’s not as easy as getting a new iPhone???

      31. I just upgraded my 918+ to 7.2 specifically for the SMB3 Multi Channel (09:35). Light years difference. I had it connected to a 10GB switch and the instant difference was amazing. I can scroll through my Lightroom Classic massive RAW files without it stuttering and pausing to refresh between pictures every two seconds. I’ve needed this for so long.

For one, I am glad they do leave some cliff hangers for the next episode..errr…upgrade so that we keep getting great and entertaining material from you both! Keep it coming!

      42. Thanks for having Rex, and showing us (in a very polite and respectful way between each other) how 2 guys can give us so many insides on the current direction and future of Synology products: and it’s a bleak one in my opinion! Despite their hardware not being easily available on a global scale and despite the extra overhead, knowledge and maintenance required I can only see my self going towards TrueNAS Scale, Unraid (but it doesn’t seem as much refined) or new upcoming (and Linus Sebastian funded) NAS product you speculated about in your previous video. Thanks

      53. Again, great video of you two. Do I get it right: you may use full volume encryption. But the key is stored locally. Therefore, if some bad guy steals my NAS and fires it up, the volume gets decrypted?

      55. Robbie, regarding the WORM folder and accidentally uploading sensitive personal data. It takes me back to an intro that you did a couple of years ago where a client of yours complained that his new NAS’s drives were already full and you found that someone had filled them with porn. Taken one more step forward – accidentally loading those videos onto the WORM folder…
