Synology DiskStation Manager (DSM) 7.1 is now available

Synology has released DSM version 7.1 to the general public. This latest release of its NAS operating system has been in development for months and is finally available to Synology enclosure owners. DiskStation Manager (DSM) 7.1 includes several major improvements. Here’s what you need to know.

What’s new in Synology DSM 7.1?

The DSM 7.1 update is fairly substantial. We’ve covered it here at length as it passed through RC channels. Here’s a quick overview of what you can expect to see after updating your Synology NAS to DSM 7.1:

  • Efficiently back up and restore all your configurations, applications, and data in DSM.
  • Improvements to our SSD cache implementation and new options to simplify SMB file server access.
  • Solutions for heavy VM use, multi-site data protection, and domain management in non-trusted environments.
  • Gain better oversight of processes and statuses throughout your deployment with more information aggregated to your preferred DSM account.
  • Be the first to benefit from the latest improvements in IT management, user experience, and security with new versions of our most-used applications.
  • SSD Cache Groups can be allocated to multiple volumes, allowing for more flexible management of SSD cache capacity.
  • Storage Manager now supports the management of the drives and storage of both active server and passive server in a Synology High Availability cluster.
  • Added support for Btrfs (Peta Volume) in Active Backup for Business and Synology High Availability.
  • If there is a file system error, DSM will unmount the volume to run file system checks without interrupting the services on other volumes.
  • Reduced the minimum threshold for low capacity notification from 5% to 3%.
  • Added support for custom OIDC (OpenID Connect) settings to integrate DSM with external SSO servers.
  • Added support for the RTF editor to allow users to preview notification message content and style in real-time when editing.
  • Added support for bypass traverse checking at Control Panel > File Services > Advanced to allow users to traverse folders and access permitted files or subfolders.
  • Supports specifying domains from the list of trusted domains to synchronize domain data.
  • Added the Greenwich Mean Time (GMT+00:00) time zone option at Control Panel > Regional Options > Time.
  • Added the synchronization status between DSM and NTP servers at Control Panel > Regional Options > Time.
  • Added icons on the taskbar to indicate ongoing background tasks that might affect system performance.
  • Users can now open tabs directly from search results in Control Panel.
  • Supports automatically updating the domain database and syncing domain data regularly. For Synology NAS that are used to create domains, the “Update User Groups/Lists” option in Control Panel > Domains/LDAP will be disabled by default after updating to DSM 7.1.

Then there are ecosystem improvements being applied to the following to coincide with the DSM 7.1 release:

  • Active Backup for Business: bandwidth control, expanded monitoring and reporting capabilities, and support for DSM backups.
  • Active Insight: centralized login activity and Hyper Backup task status monitoring, plus the ability to update monitored systems in batch.
  • Synology C2 Hybrid Share: C2 server-side snapshots in addition to local file- versioning provided by Synology Drive for easier restoration.
  • Directory Server: support for read-only domain controllers to improve deployment security and flexibility.
  • Synology Drive: expanded indexing capabilities, revamped mobile user experience, and improved monitoring/auditing capabilities.
  • MailPlus: virtual DSM support, expanded management options, importing, and migration improvements.
  • Virtual Machine Manager: storage I/O performance improvements and QoS capabilities.
