<p>Sie können das mitgelieferte Skript <code>helper-scripts/backup_and_restore.sh</code> verwenden, um mailcow automatisch zu sichern.</p>
<p>Bitte kopieren Sie dieses Skript nicht an einen anderen Ort.</p>
<p>Um ein Backup zu starten, geben Sie "backup" als ersten Parameter an und entweder eine oder mehrere zu sichernde Komponenten als folgende Parameter.
Sie können auch "all" als zweiten Parameter verwenden, um alle Komponenten zu sichern. FĂŒgen Sie <code>--delete-days n</code> an, um Sicherungen zu löschen, die Ă€lter als n Tage sind.</p>
<div class="highlight"><pre><span></span><code># Syntax:
# ./helper-scripts/backup_and_restore.sh backup (vmail|crypt|redis|rspamd|postfix|mysql|all|--delete-days)
# Alles sichern, Sicherungen Àlter als 3 Tage löschen
./helper-scripts/backup_and_restore.sh backup all --delete-days 3
# vmail-, crypt- und mysql-Daten sichern, Sicherungen löschen, die Àlter als 30 Tage sind
./helper-scripts/backup_and_restore.sh backup vmail crypt mysql --delete-days 30
# vmail sichern
./helper-scripts/backup_and_restore.sh backup vmail
</code></pre></div>
<h4 id="variablen-fur-backuprestore-skript">Variablen fĂŒr Backup/Restore Skript<a class="headerlink" href="#variablen-fur-backuprestore-skript" title="Permanent link">&para;</a></h4>
<h5 id="multithreading">Multithreading<a class="headerlink" href="#multithreading" title="Permanent link">&para;</a></h5>
<p>Seit dem 2022-10 Update ist es möglich das Skript mit Multithreading Support laufen zu lassen. Dies lĂ€sst sich sowohl fĂŒr Backups aber auch fĂŒr Restores nutzen.</p>
<p>Um das Backup/den Restore mit Multithreading zu starten muss <code>THREADS</code> als Umgebungsvariable vor dem Befehl zum starten hinzugefĂŒgt werden.</p>
<p><div class="highlight"><pre><span></span><code>THREADS=14 /opt/mailcow-dockerized/helper-scripts/backup_and_restore.sh backup all
</code></pre></div>
Die Anzahl hinter dem <code>=</code> Zeichen gibt dabei dann die Thread Anzahl an. Nehmen Sie bitte immer ihre Kernanzahl -2 um mailcow selber noch genug CPU Leistung zu lassen.</p>
<h5 id="backup-pfad">Backup Pfad<a class="headerlink" href="#backup-pfad" title="Permanent link">&para;</a></h5>
<p>Das Skript wird Sie nach einem Speicherort fĂŒr die Sicherung fragen. Innerhalb dieses Speicherortes wird es Ordner im Format "mailcow_DATE" erstellen.
Sie sollten diese Ordner nicht umbenennen, um den Wiederherstellungsprozess nicht zu stören.</p>
<p>Um ein Backup unbeaufsichtigt durchzufĂŒhren, definieren Sie MAILCOW_BACKUP_LOCATION als Umgebungsvariable, bevor Sie das Skript starten:</p>
<div class="highlight"><pre><span></span><code>MAILCOW_BACKUP_LOCATION=/opt/backup /opt/mailcow-dockerized/helper-scripts/backup_and_restore.sh backup all
</code></pre></div>
<div class="admonition tip">
<p class="admonition-title">Tipp<p>Beide oben genannten Variablen können auch kombiniert werden! Bsp:
<div class="highlight"><pre><span></span><code>MAILCOW_BACKUP_LOCATION=/opt/backup THREADS=14 /opt/mailcow-dockerized/helper-scripts/backup_and_restore.sh backup all
</code></pre></div></p>
</p>
</div>
<h4 id="cronjob">Cronjob<a class="headerlink" href="#cronjob" title="Permanent link">&para;</a></h4>
<p>Sie können das Backup-Skript regelmĂ€ĂŸig ĂŒber einen Cronjob laufen lassen. Stellen Sie sicher, dass <code>BACKUP_LOCATION</code> existiert:</p>
<div class="highlight"><pre><span></span><code>PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
5 4 * * * cd /opt/mailcow-dockerized/; MAILCOW_BACKUP_LOCATION=/mnt/mailcow_backups /opt/mailcow-dockerized/helper-scripts/backup_and_restore.sh backup mysql crypt redis --delete-days 3
</code></pre></div>
<p>StandardmĂ€ĂŸig sendet Cron das komplette Ergebnis jeder Backup-Operation per E-Mail. Wenn Sie möchten, dass cron nur im Fehlerfall (Exit-Code ungleich Null) eine E-Mail sendet, können Sie den folgenden Ausschnitt verwenden. Die Pfade mĂŒssen entsprechend Ihrer Einrichtung angepasst werden (dieses Skript ist ein Beitrag eines Benutzers).</p>
<p>Das folgende Skript kann in <code>/etc/cron.daily/mailcow-backup</code> platziert werden - vergessen Sie nicht, es mit <code>chmod +x</code> als ausfĂŒhrbar zu markieren:</p>
<div class="highlight"><pre><span></span><code>#!/bin/sh
# Backup mailcow data
# https://mailcow.github.io/mailcow-dockerized-docs/b_n_r_backup/
set -e
OUT=&quot;$(mktemp)&quot;
export MAILCOW_BACKUP_LOCATION=&quot;/opt/backup&quot;
SCRIPT=&quot;/opt/mailcow-dockerized/helper-scripts/backup_and_restore.sh&quot;
PARAMETERS=&quot;backup all&quot;
OPTIONS=&quot;--delete-days 30&quot;
# run command
set +e
&quot;${SCRIPT}&quot; ${PARAMETERS} ${OPTIONS} 2&gt;&amp;1 &gt; &quot;$OUT&quot;
RESULT=$?
if [ $RESULT -ne 0 ]
then
echo &quot;${SCRIPT} ${PARAMETERS} ${OPTIONS} encounters an error:&quot;
echo &quot;RESULT=$RESULT&quot;
echo &quot;STDOUT / STDERR:&quot;
cat &quot;$OUT&quot;
fi
</code></pre></div>

<p>Erstellen Sie das Zielverzeichnis fĂŒr mailcows Hilfsskript:
<div class="highlight"><pre><span></span><code>mkdir -p /external_share/backups/backup_script
</code></pre></div></p>
<p>Cronjobs erstellen:
<div class="highlight"><pre><span></span><code>PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
25 1 * * * rsync -aH --delete /opt/mailcow-dockerized /external_share/backups/mailcow-dockerized
40 2 * * * rsync -aH --delete /var/lib/docker/volumes /external_share/backups/var_lib_docker_volumes
5 4 * * * cd /opt/mailcow-dockerized/; BACKUP_LOCATION=/external_share/backups/backup_script /opt/mailcow-dockerized/helper-scripts/backup_and_restore.sh backup mysql crypt redis --delete-days 3
# Wenn Sie wollen, benutzen Sie das Werkzeug acl, um die Berechtigungen einiger/aller Ordner/Dateien zu sichern: getfacl -Rn /path
</code></pre></div></p>
<p>Am Zielort (in diesem Fall <code>/external_share/backups</code>) möchten Sie vielleicht Snapshot-Möglichkeiten haben (ZFS, Btrfs usw.). Machen Sie tĂ€glich einen Snapshot und bewahren Sie ihn fĂŒr n Tage auf, um ein konsistentes Backup zu erhalten.
FĂŒhren Sie <strong>kein</strong> rsync auf eine Samba-Freigabe durch, Sie mĂŒssen die richtigen Berechtigungen behalten!</p>
<p>Zum Wiederherstellen mĂŒssen Sie rsync einfach in umgekehrter Richtung ausfĂŒhren und Docker neu starten, um die Volumes erneut zu lesen. FĂŒhren Sie folgende Befehle aus:</p>
<div class="tabbed-set tabbed-alternate" data-tabs="1:2"><input checked="checked" id="__tabbed_1_1" name="__tabbed_1" type="radio" /><input id="__tabbed_1_2" name="__tabbed_1" type="radio" /><div class="tabbed-labels"><label for="__tabbed_1_1">docker compose (Plugin)</label><label for="__tabbed_1_2">docker-compose (Standalone)</label></div>
<div class="tabbed-content">
<div class="tabbed-block">
<div class="highlight"><pre><span></span><code>docker<span class="w"> </span>compose<span class="w"> </span>pull
docker<span class="w"> </span>compose<span class="w"> </span>up<span class="w"> </span>-d
</code></pre></div>
</div>
<div class="tabbed-block">
<div class="highlight"><pre><span></span><code>docker-compose<span class="w"> </span>pull
docker-compose<span class="w"> </span>up<span class="w"> </span>-d
</code></pre></div>
</div>
</div>
</div>
<p>Wenn Sie GlĂŒck haben, können Redis und MariaDB die inkonsistenten Datenbanken automatisch reparieren (wenn sie inkonsistent <em>sind</em>).
Im Falle einer beschĂ€digten Datenbank mĂŒssen Sie das Hilfsskript verwenden, um die inkonsistenten Elemente wiederherzustellen. Wenn die Wiederherstellung fehlschlĂ€gt, versuchen Sie, die Sicherungen zu extrahieren und die Dateien manuell zurĂŒck zu kopieren. Behalten Sie die Dateiberechtigungen bei!</p>
