Backup & Disaster Recovery
for SMEs

Protect your data against ransomware, hardware failures and human error. ECLAUD IT deploys and monitors your backup strategy following the 3-2-1 rule with monthly restoration tests.

Summary

60% of SMEs that lose their data close within 6 months (Cour des comptes / ANSSI 2025). The 3-2-1 rule — 3 copies, 2 media types, 1 offsite — is the minimum standard. ECLAUD IT deploys Veeam or Acronis, externalises your backups and tests restoration every month.

01 — Stakes

Why is backup the most critical component of your IT?

Ransomware encrypts your files within minutes. A hard drive fails without warning. An employee accidentally deletes a critical shared folder. Without a reliable, tested and offsite backup, these scenarios turn into disasters — sometimes into permanent closure.

02 — Standard

The 3-2-1 rule — the minimum backup standard

Recommended by ANSSI and adopted by every serious MSP, the 3-2-1 rule is straightforward:

3
copies
of your data (the original + 2 backups)
2
media types
different storage (local disk + NAS or cloud)
1
offsite
externalised copy (remote datacenter or encrypted cloud)

In 2026, some experts recommend the 3-2-1-1-0 rule: add 1 immutable copy (impossible to modify or delete, even by a compromised admin) and 0 restoration errors verified through regular testing. This is the approach ECLAUD IT deploys by default.

03 — Types

Full, incremental or differential backup?

Type Description RPO Storage
Full Complete copy of all data. The safest but slowest and most storage-intensive. Ideal as a weekly starting point. Variable High
Incremental Copies only files changed since the last backup (full or incremental). Fast and storage-efficient. < 24h Low
Differential Copies all files changed since the last full backup. Faster to restore than an incremental backup. < 24h Medium

In practice, ECLAUD IT combines a weekly full backup + daily incrementals + continuous cloud replication. This strategy delivers an RPO of a few hours and an RTO of under 4 hours.

A solid backup strategy combines local storage, cloud replication and regular restoration tests.
04 — DRP / BCP

DRP vs BCP — Disaster Recovery Plan vs Business Continuity Plan

DRP — Disaster Recovery Plan

Goal: resume operations after a disaster within a defined timeframe (RTO). Accepts a period of downtime. Suited to the majority of SMEs. Moderate cost.

BCP — Business Continuity Plan

Goal: maintain operations without interruption. Requires redundancy (clustered servers, real-time replication). High cost. For business-critical activities.

ECLAUD IT Recommendation

For an SME with 5 to 120 workstations, a DRP with a 4-hour RTO is the best cost-to-protection ratio. Externalised backups combined with a priority response contract allow you to recover quickly without over-investing in redundant infrastructure.

05 — Solutions

Veeam, Acronis and cloud solutions — what we deploy

Veeam Backup & Replication

The benchmark for virtualised environments (VMware, Hyper-V). Granular restoration, replication, immutable backups. Ideal for SMEs with on-premises servers.

Acronis Cyber Protect

Unified backup + antivirus + anti-ransomware solution. Centralised cloud console. Excellent for SMEs with a mix of workstations and servers.

Encrypted cloud backup

Externalisation to French datacenters (HDS-certified for health data). AES-256 encryption at rest and in transit. Configurable retention policies.

Microsoft 365 Backup

Microsoft 365 does not back up your data by default. We deploy a third-party solution (Veeam for M365 or Acronis) to protect Exchange, SharePoint and OneDrive.

06 — Our method

From audit to continuous protection — 6 steps

1

Business Impact Analysis (BIA)

Identification of critical systems, assessment of hourly downtime costs, definition of recovery priorities.

2

RPO / RTO Definition

RPO (Recovery Point Objective): how much data can you afford to lose? RTO (Recovery Time Objective): how quickly must you be back up and running?

3

Backup Architecture

Implementation of the 3-2-1 rule, selection of solutions (Veeam, Acronis), configuration of local and cloud replication.

4

Documentation & Procedures

Drafting the recovery plan, decision trees, emergency contacts, step-by-step restoration procedures.

5

Restoration Testing

Monthly full restoration tests in an isolated environment. Measurement of actual RTO. Documented reporting.

6

Continuous Improvement

Quarterly DRP review, updates after each infrastructure change, annual disaster simulation exercise.

07 — Costs

How much does managed backup cost for an SME?

Scope Indicative price Included
Workstations €5 — €15 / workstation / month Incremental backup, encrypted cloud, monitoring
Servers €50 — €200 / server / month Veeam/Acronis, replication, restoration tests
Full DRP On request BIA, documentation, monthly tests, guaranteed RTO
"At ECLAUD IT, workstation backup is included in the managed IT service. For servers and DRP, we offer dedicated packages with monthly documented restoration tests — that part is non-negotiable." — Enrico Claude, founder of ECLAUD IT
08 — Frequently asked questions

FAQ — Backup and Disaster Recovery

What is the 3-2-1 backup rule?

The 3-2-1 rule recommends keeping 3 copies of your data, on 2 different media types (local disk + cloud, for example), with 1 copy stored offsite (remote datacenter or cloud). This is the minimum standard recommended by ANSSI for any business.

What is the difference between a DRP and a BCP?

A DRP (Disaster Recovery Plan) aims to restore operations after a disaster — it accepts a period of downtime (RTO). A BCP (Business Continuity Plan) aims to maintain operations without interruption through redundancy (clustered servers, real-time replication). A BCP costs more but guarantees zero downtime.

How much does managed backup cost for an SME?

Managed backup costs between €5 and €15 per workstation per month and between €50 and €200 per server per month, depending on data volume and retention. At ECLAUD IT, backup is included in the managed IT service. For a full DRP with monthly testing, a dedicated package is available on request.

How often should backups be tested?

ANSSI recommends testing restoration at least once per quarter. At ECLAUD IT, we test monthly by restoring a data sample in an isolated environment. Every test is documented with the measured restoration time.

Veeam or Acronis: which solution should you choose?

Veeam is the benchmark for virtualised environments (VMware, Hyper-V) and complex server infrastructures. Acronis is excellent for SMEs with a mix of workstations and servers, thanks to its unified console and built-in ransomware protection. ECLAUD IT deploys both depending on your context.

What happens if ransomware encrypts my backups too?

This is the primary risk if your backups reside on the same network as your workstations. The 3-2-1 rule with an offsite (air-gapped or immutable) copy protects against this scenario. Veeam and Acronis offer immutable backups that even a compromised administrator cannot delete.
