Synology DSM 6.1 Betaphase beginnt

1. File Self-Healing
   • DSM is now capable of detecting and repairing silent data corruption if your Synology NAS meets the following criteria:
     • Running Btrfs file system
     • Built on RAID 1, RAID 5, RAID 6, RAID 10, or non-1 disk SHR
     • Without any SSD read-write cache mounted (This limitation will be removed in the coming release.)
2. Shared Folder Encryption
   • In addition to encrypting a shared folder as you create it, you can now encrypt an existing shared folder anytime you want.
   • With Key Manager, you can now use a USB storage device as a physical key to mount encrypted shared folders automatically without having to memorize all the encryption keys.
   • Removed the „Mount automatically on startup“ function from the edit page of shared folders.
3. Resource Monitor
   • IT administrators will receive notifications regarding performance issues of the CPU, memory, disks, or LUNs (available on XS+ and XS models).
   • I/O throughput of each process can now be monitored in Task Manager (available on models with Intel 64-bit processors).
   • Added the service-based view, allowing you to monitor resource usage of each service and application (available on models with Intel 64-bit processors).
4. File Services
   • Windows File Services and Mac File Services have been renamed SMB and AFP, respectively.
   • SMB service is now running Samba 4.4.
   • Supports Time Machine via SMB3 in Mac OS 10.12 and above.
   • Supports Bonjour service, allowing you to back up data to multiple shared folders via Time Machine.
   • Supports sparse files over the SMB protocol to enhance usage efficiency of file system space and network bandwidth.
   • You can now restore to a previous version from Windows Explorer when mounting your home folder via the SMB protocol.
   • After enabling Btrfs fast clone in SMB advanced settings, files can be copied at a faster speed when the source and destination are within the same Btrfs volume.
5. Storage Manager
   • RAID type can now be changed from SHR-1 to SHR-2, providing greater flexibility of storage expansion and better data protection. Note: Depending on your disk configuration, two additional disks may be required when changing your RAID type from SHR-1 to SHR-2. For more information, please refer to DSM Help.
   • Provides more types of disk health status to help you grasp the health info of your disks.
   • You can now migrate a single volume to a disk group and then create multiple volumes while using SHR (more flexiable for models built on the 32-bit architecture with a single volume size limit of 16TB) .
6. Flexible Update Options
   • You can apply important fixes without unnecessary system reboots.
   • In case a reboot is required to complete an update, the system will notify you via Email and in DSM, allowing you the flexibility to reboot at a time of your choice.
7. Service Modularization
   • Some of DSM’s built­-in features have been modularized into packages to ensure better system maintenance and update flexibility.
   • Modularization in DSM 6.1 Beta includes USB Copy, File Station, and File indexing.
8. Package Center
   • Automatically updates incompatible packages after the installation of DSM 6.1 Beta to boost your upgrading experience.
