Synology NAS BackBlaze B2 Cloud Backup – Part 11


We have finally made it. We’ve made it to the last section of this project. Now that we’ve set up the main services on the NAS and moved our files to it. Let back it up just in case the whole thing implodes (*knocks on wood). There is a lot of options between Cloud Sync and Hyper Backup to create a backup of the NAS and now there is a lot of options for cheap cloud storage. All of them have their pros and cons, advantages and disadvantages, and different capabilities. Today we’re configuring Synology NAS BackBlaze B2 Cloud Backup!

Synology Hyper Backup vs Synology Cloud Sync

Before we go into configuring Cloud Sync lets break down Hyper Backup vs Cloud Sync first.

  • Hyper Backup is mainly used to replicate a traditional backup software to a Cloud Storage location. You configure a standard backup retention schedule like daily, weekly, monthly etc.
  • Cloud Sync is mainly used for taking what is on the NAS and dumping it somewhere else or used to keep 2 locations in sync. You and sync a folder on your NAS to a folder in your OneDrive account. The connection can be a single direction or by directional.

Synology NAS BackBlaze B2 Cloud Backup Configuration

For this process I choose to use Backblaze B2 Cloud Storage. More specifically I’m going to configure a one-way sync to Backblaze and configure Backblaze to hold everything with version control. Lastly, in this configuration I will configuration not to download and changes from BackBlaze. This last step is a precaution just incase Backblaze is comprised then whatever changes are made will not impact the NAS files. Then I can just delete the BackBlaze container and reupload everything.

I’m not going to go through the BackBlaze account setup because it’s pretty straight forward. You create an account, create a bucket, and some encryption keys. Then you’ll need put that information into Cloud Sync. It’s a similar set up to any other vendor out there. So let’s focus on the Synology part of it.

Synology NAS Cloud Sync Configuration

First, log into your Synology and open up Package Center.

Download and install the Cloud Sync Application.

Next open Cloud Sync and Click the + sign to add a vendor.

As you can see there is a ton of vendors to choose from. We are going to pick BackBlaze B2 and click Next to continue.

For BackBlaze specifically they need the following items.

  • Account ID /applicationKeyID
  • Application Key

Once you put those 2 items in you’ll be able to select the bucket you created. If you have a bigger BackBlaze account with multiple buckets you can choose which bucket to use.

Click Next to continue.

On this page is where you start creating your synced folders. After you create the first folder you can add more folders. Since I’m using this for Backups and not synced cloud access I’ve selected “Upload local changes only” for sync direction. If you want to scope the schedule you can do so under “Schedule Settings”.

When you can enable Data Encryption you’ll have to create a password for the encryption. Don’t loose the password or else you’re backups will be useless.

Click Next to continue.

The process is complete. Click OK and you can go back to the Overview tab to see the status.

If you have more folders to sync click on Task List and you can add them there.


That is it. That is the process to easily sync your Synology NAS to Backblaze B2 Cloud Storage. I hope you’ve found this guide and the other ones in this series useful.
