If you accidentally delete a file and the backup syncs before you notice, you lose it. <a href="https://restic.net/" target="_blank" rel="noreferrer">Restic</a> solves that and adds something rsync will never provide: <strong>AES-256 encryption, deduplication, and snapshots with navigable history</strong>.</p> <h2 class="relative group">What makes Restic different <div id="what-makes-restic-different" class="anchor"></div> <span class="absolute top-0 w-6 transition-opacity opacity-0 -start-6 not-prose group-hover:opacity-100 select-none"> <a class="text-primary-300 dark:text-neutral-700 !no-underline" href="#what-makes-restic-different" aria-label="Anchor">#</a> </span> </h2> <table> <thead> <tr> <th>Feature</th> <th>rsync</th> <th>Restic</th> </tr> </thead> <tbody> <tr> <td>AES-256 encryption</td> <td>No</td> <td>Yes</td> </tr> <tr> <td>Deduplication</td> <td>No</td> <td>Yes (block-level)</td> </tr> <tr> <td>Navigable snapshots</td> <td>No</td> <td>Yes</td> </tr> <tr> <td>Multiple backends</td> <td>No</td> <td>SFTP, S3, Backblaze, rclone…</td> </tr> <tr> <td>Integrity checking</td> <td>No</td> <td><code>restic check</code></td> </tr> <tr> <td>Retention policy</td> <td>Manual</td> <td><code>restic forget --prune</code></td> </tr> </tbody> </table> <p>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.</p>https://blog.serviciosrogeliowar.com/en/posts/backups-automaticos-con-rsync-y-cron-para-docker-domestico/Mon, 04 May 2026 00:00:00 +0000https://blog.serviciosrogeliowar.com/en/posts/backups-automaticos-con-rsync-y-cron-para-docker-domestico/<h2 class="relative group">The Problem <div id="the-problem" class="anchor"></div> <span class="absolute top-0 w-6 transition-opacity opacity-0 -start-6 not-prose group-hover:opacity-100 select-none"> <a class="text-primary-300 dark:text-neutral-700 !no-underline" href="#the-problem" aria-label="Anchor">#</a> </span> </h2> <p>Recently I lost a hard drive without warning. It wasn&rsquo;t catastrophic because I had backups, but it made me aware that many hobbyists with home servers have no data protection strategy at all. If your Docker server crashes tomorrow, how long would it take you to recover it?</p> <p>In this article I share how I automated backups of my Docker infrastructure using rsync and cron. It&rsquo;s simple, efficient, and it works.</p>
