rsnapshot snapshottet nicht

[Holzohrwascherl]

Hallo Auskenner,

ich sitze im Moment recht gut, aber leider auf dem Schlauch.

Situation:

• Ubuntu Linux 20.04
• rsnapshot ist installiert
• Quellverzeichnis: /media/lv_system/Probe_Q mit ca. 300 GByte Daten
• Backupziel: /media/lv_system2/Ziel
• rsnapshot soll ein Vollbackup der Quelle im Ziel ablegen.
• Beide Verzeichnisse (Quelle, Ziel) sind vorhanden, also gemountet und beschreibbar.

Meine Konfigurationsdatei:

# If enabled, rsnapshot will write a lockfile to prevent two instances

# When sync_first is enabled, it changes the default behaviour of rsnapshot.
# Normally, when rsnapshot is called with its lowest interval

# details. The default is 0 (off).

# If enabled, rsnapshot will move the oldest directory for each interval

Vorgehen:

1. Die originale Datei /etc/rsnapshot.conf wegkopiert als Sicherung
2. Kopie der Datei bearbeitet
3. Originale Datei in /etc mit sudo gedit /etc/rsnapshot.conf geöffnet
4. Inhalt der bearbeiteten Datei reinkopiert und gespeichert
5. Konfiguraton getestet. Feedback: Syntax OK
6. Dann rsnapshot zum ersten Mal gestartet und eine Meldung erhalten, die ich nicht verstehe:

max@antec:~$ sudo rsnapshot alpha
[sudo] Passwort für max:
Setting locale to POSIX "C"
echo 21570 > /var/run/rsnapshot.pid
rm -f /var/run/rsnapshot.pid
/usr/bin/logger -p user.info -t rsnapshot[21570] /usr/bin/rsnapshot alpha: \
    completed successfully

Ich kann mir keinen Reim drauf machen. Das Verzeichnis /media/lv_system2/Ziel ist leer, es wurde nichts kopiert. Logdatei wurde im konfigurierten Verzeichnis auch keine abgelegt. Was übersehe ich?

Übrigens identisches Verhalten, wenn ich als Ziel-Verzeichnis ein beliebiges Verzeichnis in meinem Heimatverzeichnis konfiguriere.

Ich kenne das Programm nicht. Ein Blick auf die Github Seite gibt folgenden Hinweis:

Remember that it is only the lowest interval which actually does the rsync to back up the relevant source directories, the higher intervals just rotate snapshots around. Unless you have enabled sync_first in your configuration-file, in which case only the sync pseudo-interval does the actual rsync, and all real intervals just rotate snapshots.

Ich vermute, du müsstest rsnapshot sync aufrufen, damit es in deinem Setup funktioniert. Oder aber sync_first auf den Defaultwert 0 zurücksetzen.

Hat geholfen. Ich danke dir vielmals für deine Hilfe! Backup läuft jetzt nach ersten Probeläufen wie geschmiert …
