mb i was too busy running arch to watch it btw

But they are not running debian sid

Yes I do. I cooked a small python script that runs at the end of every daily backup

import subprocess
import json
import os

# Output directory
OUTPUT_DIR = "/data/dockerimages"
try:
        os.mkdir(OUTPUT_DIR)
except:
        pass

# Grab all the docker images. Each line a json string defining the image
imagenes = subprocess.Popen(["docker", "images", "--format", "json"], stdout = subprocess.PIPE, stderr = subprocess.DEVNULL).communicate()[0].decode().split("\n")

for imagen in imagenes[:-1]:
        datos = json.loads(imagen)
        # ID of the image to save
        imageid = datos["ID"]
        # Compose the output name like this
        # ghcr.io-immich-app-immich-machine-learning:release:2026-01-28:3c42f025fb7c.tar
        outputname = f"{datos["Repository"]}:{datos["Tag"]}:{datos["CreatedAt"].split(" ")[0]}:{imageid}.tar".replace("/", "-")
        # If the file already exists just skip it
        if not os.path.isfile(f"{OUTPUT_DIR}/{outputname}"):
                print(f"Saving {outputname}...")
                subprocess.run(["docker", "save", imageid, "-o", f"{OUTPUT_DIR}/{outputname}"])
        else:
                print(f"Already exists {outputname}")

26 tho this include multi container services like immich or paperless who have 4 each.

:q!
