Overview of OneDrive and Synology


Produced by Microsoft, OneDrive is a brilliant file syncing and hosting service for users to store documents, PDF files, videos and so on. Deeply integrated with Microsoft Office, Outlook, OneNote, etc., OneDrive has brought much convenience to users when dealing with different kinds of data and has been one of the most popular cloud services across the world.


Synology NAS, namely network-attached storage server, helps home users and businesses to stash files and data efficiently. As a private cloud service, Synology NAS offers users a secure and convenient ecosystem to manage and collaborate different data with colleagues in a hassle-free way.

Why Backup OneDrive to Synology?

Even though OneDrive is excellent and meets most people’s requirements, it’s not safe enough to stash important data in only one cloud service without any copy. Thus, backing up OneDrive to Synology NAS is a recommended way to protect your data. Also, users will find it easy and useful to store backups on Synology NAS for the following aspects:

  • When users want to share files on OneDrive, the internet should be always accessible. However, when it comes to sharing files on Synology NAS, users can access and share data at LAN speed without caring much about the internet bandwidth if they are in the same office.
  • OneDrive doesn’t offer users a service to help sync files from OneDrive to another cloud and users need to ask a third-party service to achieve the sync tasks across clouds. Nevertheless, Synology NAS provides users with an advanced feature called Synology Cloud Sync, allowing users to sync files from other clouds to Synology NAS and vice versa.
  • Synology NAS is much more cost-effective. Users will only need to pay for the service for one time and then users won’t worry about any subscription fee for applications and features on Synology.
