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>
