Backups are essential to ensure business continuity and protect against of data loss, system failures, or cyber attacks – and IT experts often reference the fabled ‘3-2-1’ rule when organising backups into an effective strategy.

The 3-2-1 backup rule states that businesses should have at least three copies of their data, stored on at least two different storage devices, with at least one copy being stored offsite:

1. Three Copies of Data
The first part of the 3-2-1 rule states that businesses should keep at least three copies of their data. This means that there should be two backup copies of the original data. Having multiple copies of data ensures that in case of data loss or corruption, and dramatically cuts the risk of complete data loss. As long as there’s at least one remaining backup copy, even giant corporations can always restore their data in a dire emergency.

2. Two Storage Mediums
The second part of the 3-2-1 rule states that the data should be stored on at least two different storage devices. This means that businesses should not rely on a single storage device, such as an external hard drive or a cloud server, for their backups. Storing backups on at least two different devices ensures that if one device fails, there is always a backup available from a separate source.

It’s worth noting that this principle also needs to extend to cloud-based environments: where organisations use Microsoft 365 or Google Workspace as their primary platform, secondary backups of that data needs to exist independent of that public cloud.

3. One Copy Offsite
The third and final part of the 3-2-1 rule states that businesses should keep at least one copy of their data offsite; ideally more! This means that the backup should not be stored in the same location as the original data or the other backup copies. This ensures that in case of a physical disaster, such as a fire, flood, or theft, the backup data is still safe and can be accessed from a different location.

While not perfect (cyber security experts argue modern backup solutions should probably specify immutability, for example) the 3-2-1 principle guards against each of the biggest threats to business data – destruction of the original data, failure of the device hardware holding that data, and a disaster at the site where that hardware exists – that most often causes financial losses, legal liability and repetitional damage.

By planning your backups with this rule in mind, you’ll know your business continuity is protected against common emergencies.

Many Adobe Lightroom users on iOS have suffered a crippling data loss after a faulty routine update.

Users who updated to Adobe Lightroom Mobile 5.4.0 on iPhone or iPad had their photos and software presets deleted unexpectedly.

Adobe, which develops a large suite of creative apps for the media and design-sectors, has apologised and issued an update for the fault, but made clear that the lost data is irretrievable to those without backups.

The software company’s statement clarify it is only a subset of Lightroom users who have been affected – specifically those:

• Using Lightroom Mobile 5.4.0 on an iOS device (iPhone/iPad)
• Without an Adobe Cloud Subscription, or with cloud sync disabled
• Without a separate device or cloud backup (such as iCloud) in operation, independent of Lightroom itself.

This includes many free version users who would have trialled Lightroom without a full Adobe Creative Cloud subscription.

Hundreds of unlucky users took to Adobe’s Support Forums, social media and Reddit to complain that years of photos had been lost as part of the routine update. Others flagged that restoring from local device backups deleted the restore once the app was re-opened.

As noted by The Register, Adobe’s problem is especially acute given Lightroom’s specialist popularity among professional photographers, and others who have significant time or money invested in valued images.

Users are advised to update to 5.4.1 to avoid the issue, although this will not restore lost photos. As always: please, please, please maintain an independent backup of all data you can’t afford to lose.

No need for a backup if it’s safely in the cloud, right? Wrong – here’s three reasons your team still needs to independently backup cloud data.

1. Retention Time

Popular cloud-storage platforms like Microsoft Office 365, Google G-Suite and Dropbox only retain deleted items in trash/deleted items for 30-days, with the longest ‘from beyond trash’ recovery being 90-days in some cases. Dropbox Pro and Business accounts may optionally extend this to 180 days, but this is still a limited window for many businesses.

Three months is not a long time – and users are often horrified to discover they can’t simply salvage a deleted file under any circumstances beyond this event horizon.

Astonishingly, this misunderstanding  helps contributes to top cause of business data loss being… human error. Delete (an un-backed up) file in haste, and repent at leisure.

Advisable cloud-backup platforms such as Veeam Backup for Office 365 and Barracuda Cloud to Cloud Backup can be used to keep a fully automated and distinct backup of cloud-based data, well beyond the default retention limit.

2. Single File Recovery

Some cloud storage platforms only allow the user to recover one file at a time – designed as they are to be used by large numbers of users interacting with individual files. This feels very practical, until it comes to a situation where an organisation needs to restore larger quantities of data in one go – such as cases of widespread malicious deletion by an employee or hacker.

Even on a relatively serviceable 50Mb/s broadband download connection, 1TB of data would take more than five and half-hours to restore centrally – and some platforms even require each file to be restored individually via manual control. In the short term, this might put significant pressure on a business or organisation’s ability to function.

This is something often ignored in Business Continuity planning – not just whether recovery is possible, but how long will it take. More comprehensive backup options normally allow a full, automated restore, either to the existing platform or an entirely new environment.

3. The Email Problem

Despite premature claims of email’s demise, many users still keep their entire working life in their inbox – including not only communication, but attachments.

Having moved traditional Exchange servers to the cloud, businesses often don’t have a backup for these (even in text form) beyond that of files. Why should email be any different?

A much better solution, and one that guarantees better sleep, is to put in place a backup service that includes your email estate, that is fully indexed, searchable and restorable for when you need it most.

2017

With data security making national news headlines, 2017 is only likely to put increasing pressure on businesses of all sizes to take sensible precautions.

But with IT moving so fast, what innovations are likely to lead the way through 2017? Exactly what sensible precautions will most tech-savvy companies be taking?

Cloud is good…

The worldwide push for ever more cloud-based systems appears to be unstoppable. A recent report from Synergy Research Group has suggested the global market for cloud computing grew by 25% to September 2016, reaching a staggering $148 billion in value.

It’s hard to see this not continuing, with companies relying on the convenience and automation of stashing growing quantities off-site backups in the cloud – using services like Office 365 as their private vault. As we’ve covered before: holding assets like email in the cloud actually gives you better protection than most people’s private server.

…..But Hybrid Cloud is better still.

But 2017’s smartest will be looking further ahead to Hybrid Cloud systems. As IT Pro recently noted, many companies report using more than 5 backup systems, but have no planning for speed of recovery should that data actually be needed urgently during 2017.

Getting all that data back may present a problem if your organisation is large, meaning hybrid on-site/cloud services like Lineal’s Disaster Recovery Service are likely to become the most flexible middle option. Keeping both a synchronised backup on-site, and a copy with a relatively local cloud service, leaves even the most vulnerable business with the maximum number of options.

Change your passwords

If you don’t already change passwords regularly, the security benefits cannot be overstated. Stolen data can often be circulated on the internet many times, so changing passwords regularly keeps not only your business secure, but helps prevent repeat data theft from being profitable. 

Whilst everyone still has a ‘New Year’ mindset and are prepared to accept a little change, it’s worth updating those passwords company wide. Remember to use a variety of different characters and choose something only you would ever guess.

Have a 2017 Plan A…. and a Plan B

Ransomware increasingly appears to be the organised criminal world’s cyber-weapon of choice and shows no sign of abating; expect to see more big UK high-street names get compromised this year by malicious emails. 

Antivirus companies may include ever more sophisticated heuristics to intercept malicious downloads before they begin encrypting your files, but ultimately only safe backups will ensure you can always restore to a clean set of data. Every firm should have a ‘Plan B’ for how to carry this out.

It’s all about Recovery Time

Expect to see Disaster Recovery (not just back-up and contingency) become a by-word for preparedness, with companies and organisations in every sector being judged not just by their number of backups, but by their costly hours of down-time. 

So if nothing else, start 2017 with an old piece of technology: a pen and paper. Work out what your business’ data recovery plan actually is, and how long it will take –  should the very worst happen.
