The 3-2-1 Backup Rule


The 3-2-1 Backup Rule

 Why you should follow this rule…

Backing up your private Data isn’t something you should neglect; you need to ensure that your critical information will survive any volatile situation.

Too many Businesses & individuals have suffered from data loss following system failure, file corruption, accidental deletion, or even by a natural catastrophe! Although most common of all in today’s world, will be loss through you becoming a victim to a random cyber-attack.

You may well take a duplicate 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?

Which rule is the best to apply?

Welcome the 3-2-1 Backup rule; a rigorous practice to cover almost all contingencies of data loss and requirement for recovery.

A straightforward structure for keeping all your private details & company data defended & recoverable should the worst occur.

At all times, keep at least THREE duplicates of your up-to-date data.

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

Keep TWO backup copies on unique devices or storage media.

Nothing lasts a lifetime, (asides plastic). We must all remember that storage devices will suffer a failure 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, to capitalise on peace of mind, you should always have multiple copies on exclusive devices, and they shouldn’t be the same product, with slim odds of corrupting at the same time.

Keep at least ONE backup copy off-site.

A simple, yet very significant rule. If you follow the first two rules, you’re on the right track, but if you don’t have an offsite backup, you’re not completely protected.

You’ve undoubtedly predicted why, 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.

However, 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 flop.


Why follow 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 misjudging 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 essential 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.
