Restic: encrypted backups with deduplication for your Linux server

Mon, 11 May 2026 00:00:00 +0000

I already had backups with rsync and cron, but rsync copies files, not snapshots. If you accidentally delete a file and the backup syncs before you notice, you lose it. Restic solves that and adds something rsync will never provide: AES-256 encryption, deduplication, and snapshots with navigable history.

What makes Restic different
#

Feature	rsync	Restic
AES-256 encryption	No	Yes
Deduplication	No	Yes (block-level)
Navigable snapshots	No	Yes
Multiple backends	No	SFTP, S3, Backblaze, rclone…
Integrity checking	No	`restic check`
Retention policy	Manual	`restic forget --prune`

Deduplication is especially useful for database backups and configuration directories that change little: a Restic repository with 6 months of daily backups usually takes up much less space than 180 full copies.

Systemd timers: the modern cron alternative you needed

Why I Left Cron
#

I’ve been using cron on my servers for years. It’s simple, reliable, and it works. But recently I discovered systemd timers and I’m not going back. The main reason: integrated logs in journald, no .log files scattered around the system, and better control over what happens when the server starts or reboots.

In my specific case, I had a backup that wouldn’t run if the server was off at the scheduled time. With cron, it simply got lost. With systemd timers and Persistent=true, the task runs as soon as the server boots up.

AI Agent with Claude Haiku to Generate Blog Articles from the Terminal

Why Automate Content Generation
#

Writing technical articles takes time. Between server configuration, troubleshooting, and documentation, I find little time to write. So I decided to create an AI agent to help me structure and generate drafts from the terminal.

Claude Haiku is perfect for this: it’s fast, cheap, and works well for text generation tasks. It doesn’t require powerful GPUs. I simply run a script and have an article ready to edit.

CI/CD with local GitLab Runner to automatically deploy a Hugo blog

Thu, 30 Apr 2026 00:00:00 +0000

Introduction
#

Tired of manually deploying my Hugo blog every time I publish an article. I decided to set up a local CI/CD pipeline with GitLab Runner. The result: automatic, reliable, and without depending on external services.

Prerequisites
#

You need:

A server with Docker installed
A repository on GitLab (can be self-hosted or gitlab.com)
Hugo installed locally for testing
SSH access configured on your server

Installing GitLab Runner
#

First, install GitLab Runner on your server. I did it on Docker because I already had the daemon running.
