For any business of any size, data loss is at best an inconvenience. At worst, it’s a death blow. Losing critical data, like client documents, contracts, sensitive internal files, etc., can be costly and, in some cases, irreversible.
To combat the threats of ransomware, hardware failure or plain old human error, every business can benefit from implementing a strong, straightforward backup strategy. And one of the most effective and widely recommended approaches is the 3-2-1 backup strategy.
Let’s talk about what the 3-2-1 method is, why it’s important, what tools you’ll need and how to get started. If you work with sensitive or high-volume document workflows, this is one data protection tactic you really shouldn’t ignore.
What Is the 3-2-1 Backup Strategy?
The 3-2-1 backup rule is a data protection strategy that helps you verify that your data is secure, accessible and resilient against failure. Bonus, it’s also a really simple principle:
- 3 copies of your data
- 2 different media for storage
- 1 copy stored offsite
Let’s break that down:
- Three copies: You should have one primary copy (the one you use daily) and two backup copies.
- Two types of media: Store your data on at least two different types of storage devices, like a hard drive and a cloud service or a network-attached storage (NAS) server and an external solid state drive (SSD).
- One offsite copy: Keep one backup copy in a different physical location. This helps guards against theft, natural disaster or system-wide failure.
This strategy dramatically reduces the risk of total data loss.
Why the 3-2-1 Method Matters
It’s probably not a huge stretch to assume your business handles massive volumes of data every day. That’s simply the world we’re living in. Whether you’re sharing contracts, collecting signatures, performing internal reviews or getting documents approved, you’ve got a plethora of opportunities for data loss.
You’ve probably already considered a few scenarios where the 3-2-1 rule could help you:
- Ransomware attacks: If malware encrypts your local cloud data, an isolated backup could save the day.
- Hardware failure: Hard drives and servers fail. Having multiple backups could mean you’re only ever annoyed and not scrambling to recover.
- Accidental deletion: Humans are creative, and we can be very creative when it comes to breaking things in ways you never thought possible. Even with versioning tools, human error can lead to permanent data loss.
- Natural disasters: Fires, floods or storms at your primary location could wipe out local backups. An offsite copy makes this a bump in the road, rather than a drop off a cliff.
Avoid the temptation to resort to patchwork solutions. Admit it, you’ve emailed documents to yourself before. Slap-dash habits don’t add up to real data protection. The 3-2-1 rule provides a repeatable, sustainable framework.
Fortunately, implementing 3-2-1 doesn’t require a huge investment. Remember, all you need is:
- Primary storage: This is where your active files live. Typically, they’ll be on your local system or cloud document management platform. Think of things like your local workstation, ShareFile, Google Workspace or Microsoft 365.
- Secondary backup (onsite): Your first backup should be stored on a different medium but remain onsite for quick recovery. You’re going to need tools like external hard drives, local backup servers and software like Acronis or Veeam, or built-in OS backups like Time Machine (macOS) or File History (Windows).
- Tertiary backup (offsite): This backup has to be in a different physical location. The cloud is the easiest option because the servers that handle those services could be all over the world and very probably not in your immediate area. Consider backup providers like Backblaze, Carbonite or AWS S3 Glacier.
For businesses with ongoing document workflows, like contract approvals, e-signatures and client reviews, it’s essential that you use platforms with built-in backup features or at least reliable integration options. Some solutions like ShareFile offer secure file storage, sharing and encryption all in one platform.
How to Get Started
Implementing a 3-2-1 strategy isn’t difficult and it’s not going to break the bank, but it does require a bit of planning. So let’s get you going:
- Audit your current storage practices. Where does your primary data live? Do you already have backups? Where are they stored? Make a list of your current systems and identify gaps.
- Set up your onsite backup. Purchase an external hard drive or set up an NAS for each key workstation. Schedule automatic backups using backup software. Whatever device you use for this, make sure it’s physically separate from your main storage system to reduce risk.
- Set up your offsite backup. Choose a reliable cloud backup provider. Make sure the provider encrypts data in transit and at rest. If you handle sensitive financial or legal documents, select a solution that supports compliance with your industry’s privacy standards.
- Test your backups. Many businesses think they’ve backed up their data … until they try to restore it and realize something’s broken. Avoid this. Run periodic tests to confirm that you actually can successfully retrieve your data.
- Document your backup policy. Write down your backup procedures, share them with your team and (this is important) keep them updated. Have a plan in place for updating, or it’ll never happen. This is especially important for compliance-driven industries.
- Automate everything. Set backup software to run automatically and send you alerts if anything fails. The more you automate, the more consistent your backups will be. You know it’s true.
Bonus Tip: Securely Share Documents While Maintaining Your Backup System
The 3-2-1 backup strategy remains one of the most effective ways to protect your business data. It’s simple, scalable and proven. Regardless of what data you work with, following this model reduces the risk of disruption to your business and improves your resilience.
At the same time, don’t forget the importance of secure sharing. Even if your data is backed up, you still need to send it, sign it and collaborate on it. Doing this insecurely, like via email or public links, may expose your data to risk. Instead, consider using a secure document workflow tool that:
- Encrypts data during sharing
- Requires login or access control
- Tracks file access and activity
