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 snapshotshabe 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 --pruneDamit behalte ich auch die jeweils eines pro Monat. Und die letzten drei. Das sieht dann so aus.
