Back up and restore VMs and containers in Proxmox VE
Schedule backups of Proxmox VE VMs and LXC containers with vzdump, choose snapshot, suspend or stop mode, set retention, store backups off-host and restore them from the GUI or CLI.
Containers vs virtual machines: differences, pros and cons
Containers vs virtual machines compared: how Docker and LXC share the host kernel while KVM VMs run their own, plus isolation, performance, density and when to combine both.
Create an LXC container in Proxmox VE
Download a container template and create an LXC container in Proxmox VE: unprivileged vs privileged, CPU, RAM and disk, networking, enabling nesting for Docker and starting it.
Install Proxmox VE on a dedicated server
Install Proxmox VE step by step: download the ISO, choose ZFS or LVM storage, set networking, log in to the web UI on port 8006, configure repositories and create your first VM.
KVM vs OpenVZ vs LXC: which VPS virtualization type to choose
Compare KVM, OpenVZ and LXC VPS virtualization: kernel access, resource guarantees, Docker support, performance and which type suits websites, apps, VPNs or Windows.
Manage Proxmox ISO images and LXC container templates
Upload or download ISO images to Proxmox, fetch LXC templates with pveam, choose which storage holds them, and keep the template list tidy and up to date.
Manage Proxmox LXC containers: resources, mounts and unprivileged mode
Run Proxmox LXC containers well: privileged vs unprivileged, changing CPU, RAM and disk, bind mounts for shared data, nesting for Docker, and container backups.
Migrate from an OpenVZ or LXC VPS to a KVM VPS
Move websites, databases and services from a container-based OpenVZ or LXC VPS to a KVM VPS: why moving beats converting, inventory, preparing the KVM server, copying data and switching over.
Run LXC system containers with LXD or Incus on Ubuntu
Install LXD or Incus on Ubuntu, initialise storage and networking, launch Linux system containers, set CPU and RAM limits, snapshot them and expose services to the internet.
Run plain LXC containers on Debian or Ubuntu (without LXD)
Use the classic LXC tools directly: install lxc, set up networking with lxc-net, create unprivileged containers from templates, configure resources, autostart and manage them with lxc-* commands.
Take and roll back Proxmox snapshots for VMs and containers
Use Proxmox snapshots before risky changes: which storage supports them, how to include RAM, roll back or delete them, and why a snapshot is not a backup.
