Data Backup
Data is not only the core of any business but also the significant asset for general users. Important files — like your critical work documents or personal photos — deserve a great backup strategy to protect against unexpected hardware failure, natural disasters, or simple accidental deletion. Let DSM help with robust and flexible backup solutions.
Snapshot Replication
The ultimate disaster recovery solution for your business
Snapshot Replication provides schedulable, near-instantaneous data protection, ensuring business documents in shared folders, virtual machines in iSCSI LUNs, or Docker DSM data remain safe and available in the event of disaster.
Notes: Snapshot Replication for select models only.
Cloud Station
Desktop Backup For Windows, Mac, and other devices
Whether it's your collection of vacation photos or important business documents, it's always a good idea to back up files on your computer, so data is never lost due to hardware failure or other accidents. With the Cloud Station Backup application, Synology makes it even easier to back up files from your Windows or Mac OS X computer to Synology NAS.
Synology Hyper Backup
Your backup plan, stronger than ever
Backup always comes with a big challenge － how can an enterprise keep multiple versions of backups while minimizing storage consumption? To solve this dilemma, Synology Hyper Backup provides multi-version backup, while offering friendlier experience and more public cloud support.
