Cloud Service: How to back up the data on your Synology NAS to the public cloud?
Last Updated 6 years ago

Overview

Public cloud storage is an affordable resource for individuals and small/medium businesses to back up their data offsite. With Cloud Sync, not only can you back up your data in real-time, minimizing the impact sudden disasters might bring, data can be encrypted prior to upload, assuring you that data on the cloud will not be compromised if the public cloud server is hacked.

1. Before you start

Please do the following:
  • Make sure your DiskStation is running DSM 6.0.
  • Install and run Cloud Sync on your Synology NAS. For instructions on how to install packages, please see here.

2. Back up data to a public cloud

  1. Open Cloud Sync and select the desired public cloud service. Here we will go through the steps using OneDrive.
  2. Log into your public cloud service and allow Cloud Sync access to your account.
  3. Once connection has been established, you can begin configuring your backup.
  4. Select a local and remote path.
    • Cloud Sync allows you to create multiple sync tasks within a cloud connection. If you choose to sync the root folder of the public cloud, however, no additional task can be created.
  5. Now you can set a Sync direction. For this task, I want to back up a folder from my Synology NAS to OneDrive so I'll select Upload local changes only and tick Don't remove data in the destination when it's removed in the source.
    • If required, tick Data Encryption.This will encrypt the data sent to the public cloud, and decrypt using the same password when downloading. The selected folder on your NAS will remain unencrypted. Please note that this process is irreversible.
  6. Once you have finished configuring your back up, click Next.
  7. Review your settings and click Advanced Settings if you want to configure selective sync.
  8. Here you can filter out files or file types you don't want backed up. This helps you to save space and use storage efficiently on the public cloud.
  9. Click Apply to finish creating your backup task.
    • If you enabled encryption, a key.zip file will be downloaded to your computer. Please keep it safe for future data recovery.
  10. Your back up task has now been set up.


3. Sync your data to a public cloud

Cloud Sync allows you to create multiple tasks within the same connection.
  1. Go to the Task list tab and click Create.
  2. Select a local and remote path as well as set a Sync direction. Since I want to keep these two folders in sync, I'll select Bidirectional.
  3. Finish your set up by clicking Next then Apply.
  4. You will see your task syncing in the Task list tab.

4. Sync with another cloud service

The same local folder can be backed up to two different cloud destinations, advancing the redundancy level of your data.
  1. Click the + icon on the bottom left corner.
  2. Select a public cloud service different to the one you previously set up.
  3. Log into your public cloud service and allow Cloud Sync access to your account.
  4. Once connection has been established, you can begin configuring your backup.
  5. Select a local and remote path as well as set a Sync direction. Since I want to back up this folder again, I'll select Upload local changes only and tick Don't remove data in the destination when it's removed in the source.
  6. Finish your setup by clicking Next then Apply.
  7. You can monitor the task status in the Overview tab.
Note: If multiple recovery points are required, Synology offers multi-version backup solution with data deduplication and compression capabilities.
