Blog

Technical articles, tutorials and feedback on Proxmox, virtualization, cloud and open source software.

This blog is written by Emmanuel Le Nohaïc, Proxmox systems administrator since 2013 and founder of LenoIT. The angle : no copy-paste tutorials nor theoretical posts, but analysis for IT decision-makers and operators who have to weigh technical options, operating costs and risk.

Topics are organised around three pillars : Proxmox VE and virtualization (deployment, clustering, high availability), backup and business continuity (3-2-1, DRP, Proxmox Backup Server, LTO tape backup), and migration from VMware or hyperscaler environments toward a more sovereign and controllable infrastructure.

Proxmox VE and virtualization

Proxmox VE is an open source professional hypervisor combining KVM and LXC behind a single interface. We cover the topics that matter : deployment, clustering, high availability, and the nuances that separate a hobby setup from a production-grade infrastructure.

Backup, disaster recovery and continuity

Backup is not a storage problem, it is a business continuity problem. 3-2-1 strategy, restore tests, RPO/RTO, Proxmox Backup Server : we focus on what makes your backups actually useful the day you need them.

Migration and managed services

Migrating from VMware to Proxmox, leaving the public cloud for a sovereign infrastructure, outsourcing operations partially or fully : the stakes go far beyond the technical migration itself. We share field experience.
