Habr<p>Резервное копирование в Linux: инструменты и стратегия 3-2-1</p><p>В статье делюсь методами и инструментами полного резервного копирования операционной системы Linux и рассказываю о своих практиках. Чек-лист резервного копирования здорового человека Полнота . Бэкапы должны включать все критически важные компоненты проекта: базы данных, файлы сайта, конфигурационные файлы и мультимедийный контент. Регулярность — чтобы минимизировать потери данных. Частота создания бэкапов зависит от динамики изменений на сайте. Как правило — варьируется от ежедневного до еженедельного. Надежное хранение . Резервные копии не хранят на основных серверах. Желательно использовать облачные хранилища или отдельные физические носители. Шифрование . Данные должны быть зашифрованы — это защита конфиденциальных данных от несанкционированного доступа. Критически важно! Обязательно заучиваем пароль шифрования. Проверьте — все хорошо только, если вас разбудили ночью и вы сразу и правильно его вспомнили. Автоматизация . Автоматизация процессов снижает риск человеческой ошибки. Тестирование восстановления — чтобы убедиться в работоспособности бэкапов. Версионность . Хранение нескольких версий бэкапов полезно, если пригодится восстановление данных на определенный момент времени. Прежде чем углубляться в детали инструментов и методов резервного копирования, расскажу о базовой, но чрезвычайно эффективной стратегии — основе любого плана защиты данных. Это концепция 3-2-1.</p><p><a href="https://habr.com/ru/companies/ispmanager/articles/844154/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">habr.com/ru/companies/ispmanag</span><span class="invisible">er/articles/844154/</span></a></p><p><a href="https://zhub.link/tags/%D1%81%D0%B5%D1%80%D0%B2%D0%B5%D1%80%D0%BD%D0%BE%D0%B5_%D0%B0%D0%B4%D0%BC%D0%B8%D0%BD%D0%B8%D1%81%D1%82%D1%80%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D0%B5" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>серверное_администрирование</span></a> <a href="https://zhub.link/tags/%D1%81%D0%B8%D1%81%D1%82%D0%B5%D0%BC%D0%BD%D0%BE%D0%B5_%D0%B0%D0%B4%D0%BC%D0%B8%D0%BD%D0%B8%D1%81%D1%82%D1%80%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D0%B5" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>системное_администрирование</span></a> <a href="https://zhub.link/tags/it%D0%B8%D0%BD%D1%84%D1%80%D0%B0%D1%81%D1%82%D1%80%D1%83%D0%BA%D1%82%D1%83%D1%80%D0%B0" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>itинфраструктура</span></a> #321 <a href="https://zhub.link/tags/%D1%80%D0%B5%D0%B7%D0%B5%D1%80%D0%B2%D0%BD%D0%BE%D0%B5_%D0%BA%D0%BE%D0%BF%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D0%B5" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>резервное_копирование</span></a> <a href="https://zhub.link/tags/bacula" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>bacula</span></a> <a href="https://zhub.link/tags/cyber_backup" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>cyber_backup</span></a> <a href="https://zhub.link/tags/amanda" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>amanda</span></a> <a href="https://zhub.link/tags/veeam_backup_and_replication" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>veeam_backup_and_replication</span></a> <a href="https://zhub.link/tags/acronis_cyber_protect" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>acronis_cyber_protect</span></a></p>

Dan Langille<p>At first, I was like: I'll keep the most recent backup. However, I see that each backup of is the <a href="https://bsd.network/tags/Bacula" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Bacula</span></a> database. I don't need those now.</p>

Dan Langille<p>On this fine (rainy) Sunday morning, I'd like to update my <a href="https://bsd.network/tags/Bacula" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Bacula</span></a> installation (in a <a href="https://bsd.network/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>FreeBSD</span></a> jail).</p><p>However, this is the first Sunday of the month. That means full backups are running. They take longer. They aren't done yet. </p><p>The longest job is at 46 of 53 GB left.</p><p>Now on S1E7 of Hacks.</p>
tallship<p>Ghost is an excellent platform for publishing. I used it a lot a few years back for publishing articles when it was headless - that was optimum. Compose at your leisure within your own local environment, then push it up to your own self-hosted instance.</p><p>Unfortunately, they let it fall into disrepair, left it unmaintained, and last I checked the Ghost desktop was nowhere to be found in the repo. One of the maintainers explained to me that they just didn't have anyone willing to maintain the app and so I migrated away from the platform myself.</p><p>Integrating <a class="hashtag" href="https://public.mitra.social/collections/tags/activitypub" rel="nofollow noopener noreferrer" target="_blank">#ActivityPub</a> is a fantastic idea, and will give <a class="hashtag" href="https://public.mitra.social/collections/tags/writeas" rel="nofollow noopener noreferrer" target="_blank">#WriteAs</a> a run for the money, but the reasons for leaving <a class="hashtag" href="https://public.mitra.social/collections/tags/drupal" rel="nofollow noopener noreferrer" target="_blank">#Drupal</a> and <a class="hashtag" href="https://public.mitra.social/collections/tags/wordpress" rel="nofollow noopener noreferrer" target="_blank">#WordPress</a> to publish on <a class="hashtag" href="https://public.mitra.social/collections/tags/ghost" rel="nofollow noopener noreferrer" target="_blank">#Ghost</a> aren't so compelling with editors like <a class="hashtag" href="https://public.mitra.social/collections/tags/gutenberg" rel="nofollow noopener noreferrer" target="_blank">#Gutenberg</a> exist now, along with the <a class="hashtag" href="https://public.mitra.social/collections/tags/wordpress%5Factivitypub" rel="nofollow noopener noreferrer" target="_blank">#WordPress_ActivityPub</a> plugin.</p><p>I'm going to give it another looksee to review what happened to the elegant, <a class="hashtag" href="https://public.mitra.social/collections/tags/headless" rel="nofollow noopener noreferrer" target="_blank">#headless</a> nature that Ghost used to espouse as one of it's key ingredients for using it in the first place.

Lord knows, the last time I checked their managed hosting solutions for Ghost it certainly wasn't even competitively priced.</p><p>With this newfound revelation in the form of some kind of epiphany, let's hope their commitment to <a class="hashtag" href="https://public.mitra.social/collections/tags/fediverse" rel="nofollow noopener noreferrer" target="_blank">#Fediverse</a> and FOSS exceeds that of their grasp for excessive monetization.</p><p><a class="hashtag" href="https://public.mitra.social/collections/tags/tallship" rel="nofollow noopener noreferrer" target="_blank">#tallship</a></p><p>⛵</p><p>.</p><p>RE: <a href="https://todon.eu/users/MediaActivist/statuses/112302834109929024" rel="nofollow noopener noreferrer" target="_blank">https://todon.eu/users/MediaActivist/statuses/112302834109929024</a></p><p><span class="h-card"><a class="u-url mention" href="https://todon.eu/@MediaActivist" rel="nofollow noopener noreferrer" target="_blank">@MediaActivist</a></span></p>
Dan Langille<p>It was 20 years ago this coming November that the first encryption proof-of-concept was written for <a href="https://bsd.network/tags/Bacula" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Bacula</span></a></p><p>I only know that because of the dates in this diff:</p><p><a href="https://www.langille.org/bacula-encryption/patch-src-filed-backup.c" rel="nofollow noopener noreferrer" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">langille.org/bacula-encryption</span><span class="invisible">/patch-src-filed-backup.c</span></a></p><p>Caution: very complex encryption such as this should not be tried at home.</p>

Dan Langille<p>FYI, shortly after <a href="https://bsd.network/tags/Bacula" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Bacula</span></a> 15.0.0 is released, I plan to deprecate <a href="https://bsd.network/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>FreeBSD</span></a>'s sysutils/bacula9-server - the last commit was two years ago.
