The 3-2-1 Backup Rule

The 3-2-1 Backup Rule, it could save your Business.

Why we propose you stick to the 3-2-1 Backup rule…

Backing up your data isn’t something you should entirely neglect; you need to ensure that your confidential information will withstand any unpredictable situation.

A lot of Businesses & individuals have been abandoned from data loss following system failure, file corruption, accidental deletion, or even by a natural destruction! With the most common, being an unpredicted cyber-attack, the worst kind of data loss.

You may well take a replicate of your files and save them to an external disk or dump a copy in the Cloud, but is that a secure enough backup to protect your business from total loss?


Here’s how the 3-2-1 Backup works to safeguard your critical data.

The 3-2-1 Backup rule; a rigorous practice to cover almost all eventualities of data loss and requirements for recovery.

A simple structure for keeping all your details & private company data protected & recoverable should the worst situation happen.

Always keep at least THREE copies of your most recent data.

You cannot anticipate data loss, or worse, a random cyber-attack. Having at least three self-regulating backup copies of your data helps to best mitigate the risk of loss. One copy is your original file data (on your server/s or cloud storage), with a further two replicate copies being stowed in alternate locations as your backup sources.


Keep TWO backup copies on distinctive devices or storage media.

Nothing lasts a lifetime, (asides from plastic). We must all remember that storage device will suffer a malfunction at some point, or if they are connected to your network at the point of a cyber-attack striking, may well become disease-ridden and suffer a loss too.

Consequently, in order to capitalise on peace of mind, you should always have multiple copies on unique devices, and they shouldn’t be the same product, with the risks of each device corrupting at similar times.

Store at least ONE backup copy off-site.

A submissive, yet very significant rule. If you correctly shadow the first two rules, you’re on the right path, but if you don’t have an offsite backup, you’re very much still susceptible to losing everything.

If your external hard drives, disks or cloud storage are all connected to your system, whilst it corrupts, or gets attacked, it’s all infected & your several points of recovery are lost in one fell pounce.

Though, if you’ve got a copy offsite, you will still have a recovery point to reinstate your critical systems and recover all your information should all else fail.


Why should we stick to the 3-2-1 Backup rule?

Given the upsurge in Cyber-attacks, with Ransomware hitting businesses left, right and centre, I can’t see any reason you wouldn’t want to defend your vital data.

With individuals often misinterpreting the likelihood of having a natural disaster, suffering from accidental deletion or corruption, or even the victim of a hacker. The risk factor has never been so high, with your business on the line, backup is vital to protect livelihoods.

When applying the 3-2-1 rule, don’t forget to use a full-bodied and trusted solution, which is where we come in.
