The time-trusted 3-2-1 backup strategy involves data protection using multiple backups of data. Principles of the 3-2-1 backup rule:
Here’s a simple 3-2-1 Backup rule example:
You want to secure the data residing in your computer. As per the 3-2-1 rule:
The purpose of the 3-2-1 backup rule is that there should be no data loss, even in the worst-case scenario. If an incident occurs, you should be able to recover your data from any one of the 3 sources.
IT teams can use the same 3-2-1 backup strategy to secure their organization’s data. If you are part of IT, you should always choose a solution purposefully built for data backup and disaster recovery. Before choosing your backup vendor, here are some questions that will help you plan and choose one that meets all of your needs:
What do you need to back up?
Most common are endpoints (desktops, laptops), servers (file servers, NAS, virtual machines), and SaaS apps (Microsoft 365, Google Drive). The preferred vendor must support all or most of the data sources that you need to back up.
What is your budget?
If you are a small business and your primary motive is solely data backup and recovery, stick to a simple, cost-effective solution. However, if you are part of a large organization with more than 1000 employees, list all your requirements and go with the solution that meets your needs, such as backing up and protecting data across multi-cloud environments, data centers, and edge.
What regulatory compliance protocols must you support?
Companies in the healthcare industry need to comply with HIPAA when dealing with patient record data, and financial services companies must comply with SEC, CFTC, FINRA, and exchange regulations. Ensure that your backup service provider is compliant with important regulations and frameworks.
How frequently do you want to back up data?
Frequent backups will require more storage space and high network bandwidth. If you are using on-premises storage, then you must also take into account the hardware costs, upkeep and maintenance costs, additional personnel to manage the storage system, and so on. A 100% SaaS solution with no hardware involved usually has consumption-based pricing. 100% SaaS can reduce your total cost of ownership by up to 50%.
Is the solution easy to use?
Ease of use will ensure that employees of the organization can back up and restore their data as required without IT support. This would ensure that the IT team is free to handle more critical tasks such as remotely wiping a lost device or investigating backed-up data for potential malware.
Back up frequently and regularly
You must back up your data at regular intervals throughout the day. Most companies plan to back up twice a day, such as before lunch and then again just before the end of the day. Ensure that each time you back up your data, there are two additional copies of it stored on different media or storage systems.
Before Druva, our NetApp snapshots only kept two weeks of data at a time, so if an employee needed a file from beyond that it was nearly impossible. Now we can find files quickly no matter how far back. Before Druva, our backups were taking three days to complete, and even then we would have to stop them because they had gone on too long, now they always complete within hours.

Use software that will automatically backup your data as per the 3-2-1 rule at defined intervals during the day. This will eliminate the cumbersome process of manually creating copies of the data.
Test the data recovery speed and efficiency
Backups are only good if you can recover the data when required. As straightforward as it may seem, backing up data does not guarantee that you will be able to recover the whole data. Ransomware specifically targets backups because they eliminate your failsafe first to force companies to pay the ransom.
Maintain basic cyber hygiene
Ensure you continue to adhere to cyber security practices such as using antivirus for your devices, avoiding phishing emails, refraining from uploading or adding sensitive business information on any website, using corporate VPN when sending and receiving official data while you are not in your office, refrain from connecting unknown hard drives or USB devices to your office computer, and so on.
Back up important files only
Avoid backing up unimportant data such as personal videos, pictures, cache folders, and other things that are not related to work. If you are using backup software, you can pre-define the file types and folders that you want to back up.
It absolutely is. The 3-2-1 backup rule serves as a template for any backup strategy that you want to use. Here’s is Mr. Backup (W. Curtis Preston) himself explaining how the rule applies to the cloud:
Druva’s cloud data protection solution uses AWS S3 for storing backup data. Whenever you back up any data, it is immediately encrypted using an AES 256-bit encryption key and then replicated in three separate locations. This enables you to have 4 separate copies of data in 4 different locations. As the data is encrypted, only authorized personnel from an organization can view and restore the data. Thus, you always have an offsite version of the data that is not only secure but always accessible to the right people.
Druva’s cloud-native, scalable, 100% SaaS solution takes advantage of the public cloud’s simplicity and scale to provide a single solution for backup and recovery, disaster recovery, cyber resilience, eDiscovery, legal hold, compliance, and forensics.
