Backup has become an indispensable part of our life. Can I backup Synology to cloud? Is there a cloud backup solution for Synology? Yes, Synology offers Synology C2 Storage, a cloud-based backup service for backing up your Synology NAS data.

Public cloud storage such as Google Drive, Dropbox, or OneDrive is also an affordable resource for both individuals and small/medium businesses for Synology backup. Backing up your Synology NAS to cloud can minimize the impact of sudden situations like local disk corruption or natural disasters. Here, I will introduce you to 3 effective Synology cloud backup solutions and how to backup your Synology to cloud with ease. Let's have a look.

  • Your Synology NAS is running DSM 6.0 or above.
  • Hyper Backup is installed on your Synology NAS.
  • You have a Synology Account. You can manage your Synology account on DSM at the following locations: for DSM 7.0 and above: Control Panel > Synology Account; for DSM 6.2 and below: Control Panel > Info Center > Synology Account.

Cloud Sync is a synchronization suite mainly used between the public cloud and NAS. Compared to Hyper Backup, it supports more clouds. Although it only has a synchronization function, you can choose two-way synchronization or one-way synchronization. NAS data synced to the cloud can be accessed directly, and encryption is supported to protect your data on the cloud.

1. Download Cloud Sync from the Package Center and open it from the main menu.

2. In the pop-up window, you can see all the clouds it supports. Choose the cloud service you want. Here, we take OneDrive as an example.

If you choose to sync the root folder of the public cloud, you cannot create additional tasks. If not, you can create multiple sync tasks within a cloud connection.
If necessary, tick Data Encryption, which will encrypt the data sent to the public cloud and decrypt it with the same password when downloading. The selected folder on the NAS will remain unencrypted. Please note that this process is irreversible.

5. Click Next to preview your settings. If you only want to sync specific folders or file types, click Advanced Settings.
