- Built-in data integrity check detects data and file system corruption with data and meta-data checksums and improves the overall stability.
- Flexible Shared Folder/User Quota System provides comprehensive quota control over all user accounts and shared folders.
- Advanced snapshot technology with customisable backup schedule allows up to 1,024 copies of shared folder backups in a minimum 5-minute interval without occupying huge storage capacity and system resources.
- 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.
Comprehensive Business Applications
Powered by the innovative Synology DiskStation Manager (DSM), DS918+ comes fully-equipped with applications and features designed specifically for small or growing businesses.
Virtualisation Solutions
Synology’s Virtual Machine Manager opens up abundant possibilities, allowing you to set up and run various virtual machines, including Windows, Linux, and Virtual DSM. You can also test new software versions in a sandbox environment, isolate your customers' machines, and increase the flexibility of your DS918+ with reduced hardware deployment and maintenance costs. Synology iSCSI storage fully supports most of the virtualisation solutions, enhancing work efficiency with an intuituve management interface. VMware vSphere™ 6.5 and VAAI integration help offload storage operations and optimise computation efficiency. Windows Offloaded Data Transfer (ODX) speeds up data transfer and migration rate, while OpenStack Cinder support transforms your Synology NAS into a block-based storage component.
