Führen Sie einen Anacron-Job manuell aus

11

Ich habe eine minimale Installation meines Systems durchgeführt. Ich möchte dieses System als PLEX-Medienserver verwenden. Ich habe LXDE konfiguriert, weil es eine leichte GUI ist. Ich konfiguriere mein System so, dass automatische Sicherungen mit rsnapshot erstellt werden. Ich habe meine Datei rsnapshot.conf erfolgreich konfiguriert und durch Ausführen des wöchentlichen Befehls rsnapshot im Terminal erhalte ich die gewünschten Ergebnisse.

Hier ist meine Datei rsnapshot.conf:

Ich habe einen wöchentlichen Anacron-Job in einer anacrontab-Datei erstellt:

# /etc/anacrontab: configuration file for anacron

# See anacron(8) and anacrontab(5) for details.

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

@monthly    15  cron.monthly    run-parts --report /etc/cron.monthly
7   5   backup.weekly   rsnapshot weekly >> /media/siddharth/Backup/Backup/Logs/Anacron/log

Wie teste ich, ob Anacron diesen Job fehlerfrei ausführt oder nicht?

Meistens bin ich nicht angemeldet. Wie führe ich einen Testlauf von Anacron durch?

Sie können die Ausführung eines Anacron-Jobs erzwingen, indem Sie seine Zeitstempel ignorieren.

anacron -f

Auf -nWunsch können auch andere Optionen wie verwendet werden.

Von man anacron:

 -f     Force execution of the jobs, ignoring the timestamps.

 -s     Serialize  execution  of jobs.  Anacron will not start a new job
              before the previous one finished.

 -n     Run  jobs  now.   Ignore  the  delay   specifications   in   the
              /etc/anacrontab file.  This options implies -s.

Sie können die Anmeldungen anzeigen /var/log/syslog.

Der Zeitstempel für jeden Job wird in gespeichert /var/spool/anacron.

Vielen Dank ! Es ist perfekt. Ich kann den Sicherungsjob wie erwartet ausführen. Ich hoffe, diese Antwort hilft anderen Menschen wie mir, die von Windows nach Ubuntu migrieren.

PS: Eine andere Frage: Für die Planung wöchentlicher Jobs auf einem PC, der nicht rund um die Uhr ausgeführt wird, ist Cron oder Anacron zu verwenden?

Auf jeden Fall Anacron

Sie müssen hinzufügen, sudowenn Sie nicht als root ausgeführt werden.
