What is the 3-2-1 Backup Rule?

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.

Adobe Lightroom Users Suffer Data Loss

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.

Yes, you need to backup cloud data

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.


backup cloud retention times

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.

Veeam Backup for Office 365 reinvents Backup

Recently released in beta, Veeam Backup for Office 365 is a curious idea. Remember the old days of email? A physical server in a backroom somewhere sorting your business mail like a private sorting office?

It’s not really hard to see why that setup became redundant: that trusty piece of hardware, with its installed copy of email handling software like Microsoft Exchange or Kerio, was doomed to fail eventually, whether it be from an office disaster or the finite lifespan of hardware.

Then cloud-based services came along and ensured your email was suddenly resilient to real-world dangers. A cloud backup for your Exchange Onsite was dependable, and if backing up into the cloud wasn’t enough, why not just move there entirely? No service has exemplified this virtual shift more than Microsoft Office 365 – placing your entire Exchange (and operating your inbox client too if your prefer) off-site in the cloud, and letting Microsoft worry about the data centre infrastructure, has frequently been the smart choice for both IT strategy and budgets.

For many, the cloud was backup enough, but in larger organisations or those with special regulatory demands on email retention or availability, users are increasingly wary of certain dangers from a wholesale move to the cloud.

Because internet outages aside, the offline copy you have control over is only as reliable as the client laptop of smartphone it’s stored on, and client devices are frequently even more at risk than your old server. Break your device on the same day as your office loses connectivity for any reason, and your email history is suddenly hundreds of miles away.

Enter Veeam’s newest backup product: Veeam Backup for Office 365 – which turns the concept of a hybrid backup upside down to provide something new, in the form of a local backup for Exchange Online.

Backup for Office 365 replicates a backup of your Microsoft cloud-based email and calendars to a server of your choice (a physical piece of hardware if you wish) on specific backup terms. Users can continue operating Office 365’s wonderfully tactile email service from the cloud, knowing that Veeam will provide you an up-to-date local copy your IT team can immediately seize in event of an emergency.

The actual server architecture holding the backup can be physical or virtual (which potentially makes the entire notion of ‘localised’ hybrid backup a bit abstract, but bear with us) so Veeam’s solution is adaptable in the extreme – re-saving your emails wherever you prefer, to any machine with a Microsoft operating system.

The curious thing is that this hybrid inversion actually makes a lot of practical sense, and re-introduces a critical fail-safe role for a traditional ‘on-hand’ server. Veeam’s mission statement, to always provide ‘availability for the always-on enterprise‘ (a focus on constant, utterly uncompromising uptime of IT services and data for businesses that can’t afford any downtime) is demonstrated with a technical obsession to fulfill even the most demanding business continuity planning.
