- Flexible Shared Folders and User Quota System provide comprehensive quota control on all user accounts and shared folders.
- File self-healing allows Btrfs file systems to auto-detect corrupted files using mirrored metadata and to recover broken data using RAID configurations.
- Inline compression compresses data before writing them to the drive, to optimize storage use and reduce write commands to the drives.
Powerful Backup Tools
The DS420+ offers users a range of backup solutions for cloud and physical, on premises environments. Backing up and restoring data is effortless – and completely free of licences on compatible NAS models.
