Synology releases major update for DSM, featuring significant advancements for businesses and large-scale deployments

News | 07.06.2022

Taipei, Taiwan—June 7, 2022—Synology announced the general availability of DiskStation Manager 7.1 (DSM 7.1), a significant feature expansion that introduces two major feature updates among a plethora of smaller ones:

  • the long-awaited ability to perform complete, bare-metal level backups of the entire system;
  • shared folder aggregation — letting multiple Synology NAS/SAN under different logins access the same shared folders.

We estimate there are 5 million plus active DSM installations deployed as private clouds, backup servers, surveillance server deployments, and more. Building on the solid foundation set with 7.0, we can now focus on improving customer experience by addressing the more specific challenges that our customers identify during their day-to-day use of the platform.

DiskStation Manager (DSM) 7.1. Core storage enhancements

Версия DSM 7.1 предлагает важные улучшения для управления системой хранения. Обмен данными между несколькими устройствами Synology NAS/SAN в разных местах стал значительно проще. Функция объединения общих папок использует SMB DFS для создания символических ссылок между общими папками на нескольких устройствах Synology, отображая несколько файловых серверов Synology SMB в сети как одну большую папку портала.

Full system protection

DSM 7.1 introduces complete, bare-metal level backups of the entire system. Powered by Synology Active Backup for Business, the ability to image and replicate the entire Synology system greatly accelerates recovery time objectives (RTO) in the event of a total site failure. Full system restoration capability also introduces a quick and convenient way to deploy identically configured systems.

UI updates and performance improvements

The new user interface introduced in 7.0 has been further optimized by consolidating background tasks into an administrator-friendly overview. This provides greater transparency into what is happening on the system, even across different user accounts. For Synology High Availability (SHA) clusters, users can now view and manage drives on both systems from a single instance of Storage Manager for easier maintenance and management.

On the performance side, DSM has long supported flash caching to boost random I/O performance cost-effectively. This new version will further economize SSD caching with the ability to speed up multiple storage volumes at the same time.

Ecosystem-wide improvements

Synology is also launching several major enhancements to applications and services.

  • 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, and importing/migration improvements
  • Virtual Machine Manager: storage I/O performance improvements and QoS capabilities


DSM 7.1, Surveillance Station 9.0, and other DSM applications have reached general availability and are already being deployed to Synology systems.

SRM 1.3 has been launched with the RT6600ax and will later roll out to prior Synology routers in Q3 2022.
