Backup for Architecture firms

Why Architecture firms are extra vulnerable to data loss

What makes architecture firms data a high-value target — and what happens when it's gone

Architecture firms store some of the most sensitive data in their field — including architectural drawings | bim models | planning permits. This combination of confidential records, long statutory retention obligations, and day-to-day reliance on software like Revit makes them a prime target for cybercriminals.

Ransomware groups increasingly target organisations that cannot afford downtime — and architecture firms fit that profile exactly. A firm that loses access to its architectural drawings cannot operate. Deadlines are missed, regulatory obligations are breached, and clients lose trust. Under GDPR / AVG, data must be retained for 10 years — meaning a data loss event does not just disrupt operations today, it creates legal liability that extends years into the future.

The risk is not abstract. Irreversible loss of bim models, ransomware during active project delivery, liability exposure from missing permits is the leading threat for this sector. Files with characteristics like very large bim/cad files | planning permission archives are difficult or impossible to reconstruct from memory once lost. Every day without a verified, offsite backup is a day of unnecessary exposure.

The misconception that costs many architecture firms dearly

"Our designs are in Revit on a shared server — the IT company manages the backups."

It is easy to understand why many architecture firms believe this. Revit is marketed as a professional-grade platform, and vendors naturally emphasise uptime and reliability. But there is a critical difference between redundancy and recovery. A system can be highly available and still offer you zero protection the moment ransomware encrypts your files or an administrator accidentally deletes a directory.

Synchronisation tools — including those built into Revit — propagate changes in near real-time. When ransomware encrypts a file, that encrypted version immediately overwrites your 'backed up' copy. By the time the attack is discovered, every sync destination contains the same unusable data. This is not a backup. It is a perfectly synchronised disaster.

The practical consequence: without an independent, immutable backup, architecture firms facing a ransomware attack have two options — pay the ransom or start over. Neither is acceptable when GDPR / AVG requires you to demonstrate full data integrity to regulators.

What do I need to back up if I use Revit?

The data architecture firms typically overlook when using Revit

Revit manages your day-to-day workflow, but its built-in data protection typically covers only what happens within the application itself. It does not automatically back up your entire data environment — and there are several categories of data that fall outside its scope entirely.

For architecture firms using Revit, the following should be included in any proper backup: architectural drawings, bim models, planning permits, client correspondence. If you also use AutoCAD, any data in those systems must be covered separately.

Pay particular attention to very large bim/cad files | planning permission archives. These file types are either difficult to reconstruct or subject to strict legal retention requirements. A backup strategy that does not explicitly cover them is incomplete — and potentially non-compliant.

What a proper backup actually does

The 3-2-1 rule — and why it matters for architecture firms

The 3-2-1 rule is the baseline standard for data resilience: keep at least 3 copies of your data, on 2 different types of storage media, with 1 copy stored offsite. For architecture firms, this is not just best practice — it is increasingly a regulatory expectation under frameworks like GDPR / AVG.

In practice: your primary production data counts as copy 1. A local backup (on a NAS or secondary server) is copy 2, enabling fast recovery without waiting for a cloud download. Copy 3 is stored in an offsite data centre — physically and logically separated from your main environment, so a fire, flood, or ransomware attack cannot reach all three copies simultaneously.

Mindtime extends this to a 4-copy model, with an additional snapshot stored in a second Dutch data centre. For architecture firms managing architectural drawings, this means your data is always recoverable — from a clean, pre-attack restore point — regardless of what happens on-site.

How do architecture firms protect themselves against ransomware?

Specific measures for architecture firms — beyond antivirus

Ransomware attacks on architecture firms typically follow a predictable pattern: initial access via a phishing email or compromised credential, lateral movement to identify high-value data, and then encryption of everything — including network shares and connected backup drives.

The single most effective defensive measure is an immutable offsite backup — one that ransomware cannot reach. Beyond backup, architecture firms should implement: multi-factor authentication on all systems (particularly Revit), regular software updates and patch management, network segmentation to limit lateral movement, and staff awareness training on phishing recognitions.

Critically, a backup is only useful if it has been tested. Many organisations discover during a recovery that their backup is incomplete, out of date, or corrupted. Mindtime performs automated integrity checks on every backup and alerts you if a backup fails — so you know your data is recoverable before you need it, not during a crisis.

How do I create a backup if I use Revit?

A practical guide for architecture firms using Revit

Setting up a proper backup for architecture firms using Revit (and AutoCAD if applicable) involves more than activating the export function in your software. Here is the practical approach:

First, identify all data that must be retained under GDPR / AVG — including architectural drawings | bim models | planning permits. Map every location where this data lives: within Revit, on local drives, on shared network folders, and in any integrated third-party tools.

Second, configure Mindtime's agent on each endpoint and server that holds architecture firms data. The agent performs incremental backups continuously, so you are never more than a few minutes behind your last recovery point. Backup frequency, retention periods, and encryption settings are all configured to meet your specific regulatory requirements.

Third, run a test restore within the first week. Verify that architectural drawings and other critical data types can be recovered fully and within your acceptable downtime window. Document the process so your team knows exactly what to do if an incident occurs.

Data retention and compliance obligations for architecture firms

GDPR / AVG and what it means for your backup strategy

Architecture firms operate under some of the most specific data retention obligations in their field. The primary framework is GDPR / AVG, which sets clear requirements for how long architectural drawings must be kept, in what format, and with what level of accessibility.

Key retention requirements for architecture firms:

— 10 years (project liability)

— 7 years (fiscal)

— Planning permits: permanent

Beyond retention duration, these regulations also require that data remains accessible and verifiable throughout the retention period. A backup that cannot be searched, exported, or audited does not satisfy the requirement. Mindtime's backup platform includes point-in-time restore, meaning you can retrieve any version of a file at any point within the retention window — exactly what regulators require during an audit.

Certification under ISO 9001 demonstrates that your data protection processes meet a recognised standard — which regulators and clients increasingly expect.
