Efficient backup of lxc containers in Proxmox

Lxc containers are fast, small and useful. Proxmox Backup Server is quite slow with them, so here's how to perform a fast and efficient backup using Borg.

Docker-ize your Services - Part 3 - docker-compose

docker-compose allows you to define a set of containers in a single file. They will be in their “namespace” and can be linked and tied together.

Docker-ize your Services - Part 2 - Web Server

We can use docker both for static and dynamic websites. We have a wide choice of images - and we can even create our own.

What I’ll be describing now is another kind of setup, based on two containers, and it will help you to understand some of the features of Docker.

Docker-ize your services - Part 0 - Introducing Docker

Docker has been a fundamental part of my setup for more than three years now. Day after day I tried to move as many services as possible to Docker and this was a very good move.

Proxmox Backup Server - hints for a perfect deployment

Proxmox Backup Server (PBS) has been released. It's still in beta but is already perfectly usable. After many years, it's now possible to perform incremental backups of the VMs and thanks to the qemu dirty bitmaps, backups are also fast.

Take automatic snapshots of cephfs file systems

Cephfs is great. It can be used to store and share files and can take advantage of the granularity and performance of Ceph. Big amounts of data can be stored and live snapshots can be taken so remote backups can be easily performed.

BTRFS: performing automatic snapshots and remote backups

One of the interesting features of BTRFS is the dynamic snapshot generation, which grantees the possibility to have a perfect and immediate copy of a specific path.
