A Guide to Backblaze B2 Synology: Connecting Synology NAS to Backblaze B2

After adding a Synology Network Attached Storage (NAS) device to your tech stack, the next logical step is to secure your data and protect it from accidental deletion, natural disasters, death breaches, malware, ransomware, and other cyber threats.

However, it’s hard to accomplish such a task when you don’t know how to do it. Thankfully, cloud storage is still the best way to ensure maximum data security. Cloud storage solutions like Backblaze B2 excel at preventing data loss and are paramount to maintaining top levels of cybersecurity.

If you learn how to back up your Synology NAS to Backblaze, you’ll avoid losing or deleting precious data.

Part 1. What Is Backblaze B2?

Backblaze B2 is an affordable, reliable, and user-friendly cloud storage solution for saving sensitive data securely in the cloud environment. The cloud service keeps your data easily accessible via a browser-compatible URL or API.

As a service user, you create an account to unlock Backblaze B2 features, such as daily 1GB of free downloads, unlimited free uploads, and 10GB of free storage. After creating your account, you’ll get access to your Application Key and Application Key Id to manage APIs.

In addition, an account gives you access to two B2 API suites:

  • B2 Native – an ideal solution for accessing the B2 Native API to manage functionalities such as lifecycle rules and application keys.
  • S3 Compatible – recommended for the latest integrations and applications as S3 supports a number of libraries and SDKs.

BackBlaze B2 APIs allow you to save your data in specialized, easily managed file buckets and download, upload, or delete data according to your needs. They also keep your data readily accessible 24/7.

Part 2. Why Backup Synology NAS to BackBlaze

Many modern-day business organizations rely on solutions like Synology NAS to protect their data due to its many benefits.

While all these benefits can take your operations to the next level, Synology NAS alone won’t be enough to ensure complete protection for your sensitive data against major hard disk failure, ransomware/malware, and other cyber threats.

Since your data is the lifeblood of your business organization, you need a more cyberattack-proof solution. Backing up Synology NAS to Backblaze B2 and implementing a 3-2-1 strategy is a surefire way to back up data to the cloud and incorporate your NAS with as many offline copies as necessary.

Adopt a 3-2-1 Strategy

Adopting the 3-2-1 backup strategy means creating at least three copies of data in the following manner:

  • Store three copies of corporate data on-site;
  • Store two copies of your data on different devices or mediums;
  • Keep one or more copies off-site.

Synology NAS users should keep two data copies locally on different devices before backing up to the cloud.

When you back your Synology NAS to Backblaze B2, you complete the 3-2-1 strategy by keeping at least one copy off-site.

That’s why backing up to Backblaze B2 is the best option to keep multiple copies of your data safely stored and always accessible.

Better Scalability

As your business organization grows, you’ll have to manage more data than before. Many businesses find scaling a challenge.

However, you can quickly resolve it by backing up your data to Backblaze B2. Since it’s cloud storage, it will scale up or down with your data.

If your data grows, your cloud backup will scale up with it. Aside from better scalability, you’ll save resources on investing in maintaining additional hardware.

Automation Capabilities

Backing up your Synology NAS to Backblaze B2 lends you the power of automation. You can schedule automated backups in advance using a Synology NAS built-in backup functionality and focus on more urgent business matters.

Better Accessibility

Backblaze B2 keeps your data backups readily accessible via any device, anywhere, and at any time. Whether you need to retrieve a file on the go or from your office, you can pull the information you need by simply logging into your Backblaze account.

Prevent Data Loss

Perhaps the biggest benefit of opting for Backblaze B2 data storage is to avoid and prevent data loss. If the worst happens, your NAS, individual workstations, and on-site will be lost.

Since NAS requires a 24/7 connection to operate, it can increase the risk of cyber-attacks, such as malware and ransomware infection.

In addition, NAS hard drives are prone to failure, especially those set up in a RAID. You can avoid all these risks by backing up to Backblaze B2 and accessing off-site data copies on demand.
