Synology DSM 7.0: New features, eligible models, how to install, and more!

Synology makes the best NAS enclosures you can buy today, and the brand's main differentiator is the software. DiskStation Manager (DSM) has powerful features that let you easily back up data, host your own mail, office, and VPN server, and so much more.

DiskStation Manager 6.0 launched back in 2016, and while the software picked up a lot of updates in the last four years, the core features have remained unchanged for the most part. That's why it's exciting to see that Synology is now rolling out the stable version of DiskStation Manager 7.0. DSM 7.0 brings a ton of new features, including a unified photo management service, fresh user interface, better system monitoring tools, new sharing and collaboration features, and more.

Here's everything you need to know about all the new features in DiskStation Manager 7.0, what NAS enclosures are eligible for the beta, and how you can install DSM 7.0 on your NAS right now.

What are the new features in DSM 7.0?

DSM 7.0 comes with redesigned storage management features that make it easier than ever to configure storage volumes and switch out hard drives. You can now see just how much data every individual DSM package is using, identify issues with any drives in the storage pool, and there are welcome enhancements to SSD caching.

Synology Photos is an interesting new addition that merges the Moments service with Photo Station, with the package now being the default photo management service on DSM. The service relies on AI to automatically sort and categorize images into albums, and it offers a seamless way to back up photos from all the phones connected on your home network to your NAS.

Active Insight is a centralized dashboard that lets you control all Synology NAS enclosures registered under the same account, so if you remotely manage a NAS, the feature definitely comes in handy. Synology Drive is getting an admin console that monitor file transfers, usage trends, and much more. And there's Hybrid Share, a useful tool for small businesses that hooks into Synology's C2 cloud service and backs up data, making it accessible across different locations.

There are also exciting changes around file sharing, security, and virtualization. The detailed release notes list all the new additions in DSM 7.0:

How to install DSM 7.0 on your NAS

Before you install DSM 7.0, there are a few points to consider. There's no way to downgrade to DSM 6.2 following the switch, so make sure you're ready to take the plunge. To install DSM 7.0, you'll have to make sure that your NAS is currently running DSM 6.2 or above. Head to Control Panel > Update & Restore to see if your NAS is on DSM 6.2, and install any updates available.

DSM 7.0 is rolling out as a stable build, so it should be available as an OTA update for your NAS. But if it isn't available on your NAS just yet, you can easily install it manually. Here's how you can install the stable version of DSM 7.0 on your NAS:

1. Go to the Synology Download Center to download the DSM 7.0 package for your NAS.
2. In the Select product type menu, select NAS.
3. Enter your NAS model name or scroll down the list to locate it.
4. You should see all the OS packages for your NAS. To see the DSM 7.0 build, you will have to change the OS Version (it's located on the right of the page) from the default 6.2 series to 7.0 series.
5. You should now see the DSM 7.0 RC build package show up. Hit the Download button to start the download. The build will save as a .pat file.
6. Once the build is downloaded, you'll have to head over to your NAS to initiate the update. Within DSM 6.2, navigate to Control Panel.
7. Choose Update and Restore within the System section.
8. Select Manual DSM Update.
9. You can use the Browse button to locate the DSM 7.0 build that you downloaded earlier. This will be the .pat file.
10. Once you've found the file, hit OK to start updating your NAS to DSM 7.0.

It should take anywhere from 10 to 20 minutes to install DSM 7.0. The new visual design combined with exciting new features like Photos and Active Insight make DSM 7.0 a noteworthy update, and if you've been waiting to install the build on your NAS, now is the time to do so.
