- File or folder level data restoration brings huge conveniences and saves time for users who wish to restore only a specific file or folder.
- File self-healing: Btrfs file system can auto-detect corrupted files with mirrored metadata, and recover broken data using the supported RAID volumes, which include RAID1, 5, 6, and 10.

Effective Sync & Backup Solution
DS418play can serve as a centralised backup destination, making it easy to create your own private cloud.
