Your data
survives
the worst.

Centralised storage, off-site and tested backups, disaster recovery planning. And if the worst happens, data recovery and disk cloning before any intervention.

No commitment · Everything under NDA from the first message

Sound familiar?

An untested backup
is just a hope.

The day you need to restore, you often discover the backup is incomplete, outdated or encrypted too.

Your data is scattered

Files on workstations, USB sticks, external drives: nobody knows where the latest version is.

Your backups have never been restored

They run — in theory. Nobody has checked they actually let you restart.

Ransomware encrypts the backups too

A backup reachable from the network is often the attacker’s first target.

A disk has failed

Data out of reach, a system that won’t boot: every attempt can make things worse.

What we do

Store, protect,
restore.

A complete data strategy, from everyday use to disaster recovery.

01
Centralised storage

One single source of truth

NAS and shared storage, access rights per department, encryption of sensitive data.

02
Backups

Copies that hold up

Automated backups, off-site copies isolated from the network, retention tailored to your needs.

When the worst has happened

Disk cloning before intervention, data recovery and evidence preservation in the event of an incident.

Our method

A strategy
verified, not assumed.

01

Inventory

Where your data is, which data is critical, how long you can do without it.

02

Architecture

Storage, backups and off-site copies sized for your needs.

03

Implementation

Deployment, automation and a first full restore test.

04

Verification

Regular restore tests and a report on backup health.

What you get

What you get.
The certainty you can restart.

Tested restores

Documented proof that your backups work.

Copies out of reach

At least one isolated copy the attacker can’t encrypt.

A written plan

Who does what, in what order, on the day you need to restart.
