The 3-2-1 Rule of Backup: Safeguarding Your Data

With the growing threat of ransomware, viruses, and malware attacks, the importance of data backup has increased. It not only safeguards your data from the perils of the internet but also protects against accidental deletion, hardware failures, or other server mishaps that might cause data loss. The 3-2-1 backup rule is at the heart of any robust data protection plan. It's a strategy that's widely adopted in most IT sectors today. Read on to learn more about the 3-2-1 data backup rule in this guide.

"3-2-1 Backup" is a backup strategy that involves keeping three separate copies of data, stored on two different types of media, with at least one copy backed up offsite. Specifically: - The "3" represents having three copies: the original data and two additional backups. - The "2" means using two distinct storage mediums, such as hard drives, tape, network-attached storage (NAS), or cloud storage. - The "1" indicates that at least one backup copy is stored in a location physically separate from the original data, safeguarding against regional disasters or data center failures. This backup strategy ensures high availability and durability of data, minimizing the risk of data loss.

American photographer Peter Krogh introduced the 3-2-1 backup rule, which was groundbreaking for photography and has had far-reaching effects in other technical disciplines. The rule is flexible and timeless. According to the 3-2-1 backup rule, one should keep three copies of data on two different kinds of media, with at least one copy offline. Here are the details of each element.

Three copies or versions of the data

By saving three copies or versions of data at different points in time, users can more easily recover lost data in the event of an accident. A robust backup system will provide more than three copies of your data to ensure your stored information is safe throughout the process.

Two different media or platforms

It is generally advisable not to keep all copies of your data on the same medium. Make sure to use different media platforms to ensure the safety of your data. You can save one copy of your data for use with your hard drive using Disk Utility, and easily create a virtual volume of the second copy of your data. That way, if any of these drives fail, you can quickly recover your data. Keeping a copy of your data on a backup medium separate from the original medium ensures longer-term access.

A remote backup

It is advisable to keep physical copies of your stored data in different locations to safeguard against data loss in case of an emergency. Keeping backup files offsite makes them easier to access should your server fail. You can physically protect your data using tools such as flash drives, DVDs, hard disk drives, or solid-state drives.

Why is the 3-2-1 backup rule important?

The "3-2-1 backup rule" is one of the best practices for ensuring the safety of your data throughout its lifecycle. This rule, endorsed and employed by multiple government agencies and cybersecurity professionals, mitigates much of the risk to your data, ensures its availability, and guards against any single point of failure. In the event of file corruption or physical incidents such as natural disasters or theft, this rule helps keep your data secure. Here are some of the main benefits offered by this backup strategy:

Reliability

The 3-2-1 backup rule is a reliability safeguard. It protects your data from viruses, malware, ransomware, and other failures. This strategy is endorsed by various cybersecurity experts and government agencies, making it a more reliable option.

Usability

With 3-2-1 backup, data is stored in the cloud, making it easier for users to access it from anywhere with a secure username and password.

Security

The "3-2-1 backup rule" is a strategy for safeguarding your data. It involves backing up and storing your information on three separate platforms, ensuring easy access from anywhere, at any time.

How do you implement the 3-2-1 backup rule?

Failing to adopt a 3-2-1 backup strategy puts you at significant risk in the event of a cyberattack or data breach. If your business is affected, the scale of the loss can become intolerable. When choosing a backup plan, make sure it adheres to the 3-2-1 backup rule. If it doesn't, you can easily opt for cloud or other backup options.

Method 1: Using Common Backup Software

Well, if ya look around the market, you'll find plenty of backup software options to keep your data secure. Plus, you can backup your stuff on Google Drive or OneDrive. To do that, just head over to your device's settings, then jump into Google, and from there, hit Backup. When you spot it, tap 'Backup Now' to get the ball rollin'.

Method 2: Back Up with a NAS

Centralized storage, in the form of Network-Attached Storage (NAS), is an excellent solution for backing up data. It provides ample backup storage space for local devices and protects your data from disasters. NAS offers users offsite data backup, which is crucial for data security as it keeps sensitive information safe and facilitates effective disaster recovery.

Steps for Backing Up with a NAS

These are general steps that apply to all NAS devices, but there may be slight differences depending on the software and hardware you're using for your NAS.

Step 1: Install the NAS software on your computer and connect the NAS to the same network as your computer. This ensures a quick location for backup.

Step 2: Launch the NAS backup software, and after completing the initial setup, select the files you want to back up.

Step 3: From here, you can set up automatic backups on a schedule, or perform a one-time backup. Some programs also offer encryption, which is an added layer of security for your backups.

Step 4: Finally, choose the backup location on your NAS server, or keep the default setting. Start the backup and wait for it to complete.

Now that you know how to back up to a NAS, you can apply the following strategies to ensure your NAS backups are effective:

Update as soon as possible

Updates can go a long way in improving the performance of your NAS and help you stay on top of security vulnerabilities effectively. Keep checking for updates and set reminders if you find any.

Two-factor authentication

Two-factor authentication ensures that only authorized users can access your backup data or systems. It eliminates the risk of shared credentials and reduces the likelihood of theft.

Use HTTPS

Utilizing an HTTPS connection also contributes to enhancing data security. It ensures that your data and requests remain secure during transmission, preventing interception or modification. You'll need to obtain an SSL (Secure Socket Layer) certificate to enable HTTPS.

Firewall Settings

This is another piece of the security puzzle, allowing users to monitor and filter traffic to their NAS, which offers connections only to approved contacts.

Conclusions

So, folks! It's all about the 3-2-1 backup rule. We're all concerned about data safety, but not everyone maintains it at a higher level. This guide sheds light on the 3-2-1 backup rule, why you should opt for it, and its solutions. Hopefully, you can now back up your preferred data conveniently and access it anytime.
