Die Restic Parameter
The "prune" command checks the repository and removes data that is not
referenced and therefore not needed any more.

wird noch überarbeitet, nur mal kurz hier reingeschmissen
Ich habe mich damit noch ein wenig beschäftigt, die letzten drei zu behalten, ist nicht so optimal. Da es viele Optionen bei dem Befehl gibt, hier ein Ausschnitt
Flags:
-l, --keep-last n keep the last n snapshots
-H, --keep-hourly n keep the last n hourly snapshots
-d, --keep-daily n keep the last n daily snapshots
-w, --keep-weekly n keep the last n weekly snapshots
-m, --keep-monthly n keep the last n monthly snapshots
-y, --keep-yearly n keep the last n yearly snapshots
habe ich das ein wenig so angepasst, das ich denke es passt für mich.
restic --password-file /root/passwd -r /media/NAS_neu/Restic/Home/ forget --keep-last 3 --keep-monthly 3 --prune
Damit behalte ich auch die jeweils eines pro Monat. Und die letzten drei. Das sieht dann so aus.

Am Ende seht ihr noch, wie Restic alle Files testet. Mein Script sieht jetzt so aus.
#!/bin/bash
# Script um mit Restic Daten automatisiert zu sichern!
# Dient zum Sichern der Homepartition auf dem ROCKPro64 NAS!
# Was soll gesichert werden?
backup_pfad=/home/frank
# Programm Start
restic --password-file /root/passwd -r /media/NAS_neu/Restic/Home/ backup $backup_pfad --exclude-file=excludes.txt
restic --password-file /root/passwd -r /media/NAS_neu/Restic/Home/ forget --keep-last 3 --keep-monthly 3 --prune
# Testen
restic --password-file /root/passwd -r /media/NAS_neu/Restic/Home/ check --read-data
Das dann schön mit einem Cronjob laufen lassen und die Datensicherung ist erledigt
