Storage · Backup · Resilience

Your data available.
Your backups truly restorable.

RDMC designs, deploys and operates storage and backup architectures that withstand incidents, human error, hardware failures and ransomware attacks. From primary data to immutable vaults, we cover the full protection lifecycle.

Infrastructure & capacity

Distributed infrastructure to protect and move your data.

Our architecture combines storage capacity, geographic distribution and high-speed connectivity to meet backup, replication and disaster-recovery requirements.

Our approach

A protection chain, not just a backup.

Resilience does not depend on a single product. It relies on a coherent architecture, independent copies, retention policies, integrity checks and regularly tested restores.

Primary storage

Production volume architecture tailored to performance, availability, capacity and workloads.

NASSANNVMeS3Object

Backup & snapshots

Protection for VMs, servers, endpoints, databases, applications, containers and cloud workloads.

FullIncrementalSnapshotCDP

Immutability & WORM

Non-modifiable copies for a defined period to limit the impact of compromise or ransomware.

WORMObject LockHardened Repo

Multisite replication

Local, remote or cloud replication with failure-domain segmentation and tailored RPO targets.

Secondary siteCloudAsynchronous

Archiving & retention

Long-term retention, tiering, cold storage, lifecycle policies and cost control.

ArchiveCold storageLifecycle

Restore testing

Consistency checks, isolated restores, application validation and documented recovery procedures.

RestoreSandboxIntegrity check
Reference architecture

From production systems to the data vault.

We separate storage layers and responsibilities so that a production incident cannot compromise all copies at once.

01 · PROD

Active data

Servers, VMs, databases, files, cloud workloads, SaaS and critical endpoints.

02 · LOCAL

Fast backup

Local repository optimized for fast restores and short RTOs.

03 · OFFSITE

Offsite copy

Replication to a second site or cloud independent from the primary failure domain.

04 · IMMUTABLE

WORM copy

Locked retention with deletion or modification impossible during the defined period.

05 · VALIDATE

Validate & test

Integrity validation, restore tests and gap tracking.

Understanding the 3‑2‑1 rule

Three copies, two technologies, one offsite copy.

The 3‑2‑1 rule aims to prevent a single incident — hardware failure, human error, disaster or ransomware — from making production data and all its backups unavailable at once.

01

Production data

The active copy used by applications, users, databases, VMs or business services.

02

Distinct technologies

For example: primary storage on SAN/NAS and backup on a dedicated repository, object storage, tape or another independent medium.

03

Offsite copy

A third copy is kept on a second site or in a distinct cloud so it survives a local disaster.

Tamper protection

WORM & immutable storage

A backup reachable with the same privileges as production remains vulnerable. We deploy immutability mechanisms designed to prevent premature modification or deletion of protected copies.

  • Object Lock and retention policies
  • Hardened repositories and separated accounts
  • Deferred deletion and erase protection
  • Logical or physical air gap as required
  • Logging and operation traceability
Defense in depth

Reduce the blast radius

We isolate backup access, identities and networks so that compromise of the primary IT estate does not automatically grant access to standby repositories.

  • MFA and dedicated admin accounts
  • Network segmentation of backup traffic
  • RBAC and least-privilege principle
  • Hardening of appliances and systems
  • Monitoring of deletions and retention changes
Business continuity

RPO, RTO and recovery: backups must serve a business objective.

We align backup and replication technologies with real service criticality: file restore, VM recovery, full application rebuild or site restart.

Understanding RPO & RTO

How much data can we afford to lose, and how long can we remain unavailable ?

RPO measures the maximum acceptable data loss before the incident. RTO measures the maximum acceptable time to restore the service after the incident.

RPO · acceptable data loss
RTO · acceptable recovery time
Last valid copy08:45
Incident09:00
Service restored10:00
RPO = 15 min

If an incident occurs at 09:00, the goal is to return to a consistent state no older than 08:45.

RTO = 1 h

The service must be restored by 10:00 at the latest, even if full infrastructure remediation continues afterward.

RDMC managed services

Design, operate, verify and restore.

We can engage on a project basis or as a managed service with monitoring, operational maintenance, capacity, security and regular testing.

Audit & mapping

Inventory of workloads, dependencies, criticality, volume, retention, risks and recovery objectives.

Design & architecture

Sizing of repositories, object storage, inter-site links, retention tiers and recovery strategy.

Deployment & migration

Implementation, migration of existing policies, automation and procedure documentation.

24/7 monitoring

Tracking of jobs, capacity, backup windows, errors, SLAs, alerts and retention drift.

Restore testing

Planned recovery scenarios to validate RPO/RTO and detect unusable backups before an incident.

Ops & optimization

Patching, hardening, capacity growth, cost analysis and policy adaptation as the IT estate evolves.

Use cases

One strategy, adapted to every environment.

On‑premises infrastructure, public cloud, private cloud, hybrid, distributed sites, industrial environments, Microsoft 365, Kubernetes, databases or user endpoints: the protection policy must cover data wherever it resides.

Is your backup truly restorable?

RDMC can audit your current strategy, identify failure points, verify immutability and propose a target architecture aligned with your security, cost and availability constraints.
