Comment on Paperless cloud backups https:// samsm.ch/paperless-cloud-backu ps/

@lokalhorst As I mentioned in the post, this method can be used to back up to many different providers (incl. hetzner, see https://rclone.org/docs/). I assume w/ restic you're just backing up the folder where paperless stores the docs rather than the export. IMO the latter is nice because leaves you w/ something that's more useful w/o paperless.

I actually use the document_exporter of paperless-ngx. I have a small bash script backup-paperless.sh that runs the paperless-ngx document_exporter and also makes a database dump using pg_dump. It sets up the restic backups logic with daily, weekly and monthly backups. I run that bash script using a systemd service paperless-backup.service. This service is run daily with the timer paperless-backup.timer, randomly at 3 am ±30 minutes. restic is smart, so it does only backup if there are changes. The incremental backups are great, in case the database corrupts without me noticing. I’ll share the scripts in case you are interested in how it works:

backup-paperless.sh

#!/bin/bash
set -euo pipefail

COMPOSE_DIR="/home/user/paperless-ngx/"
DUMP_DIR="$COMPOSE_DIR/sqldump"
EXPORT_DIR="/usr/src/paperless/export"

export RESTIC_REPOSITORY="sftp:abc123@abc123.your-storagebox.de:/backup/restic"
export RESTIC_PASSWORD_FILE="/home/user/.config/restic/password"

mkdir -p "$DUMP_DIR"

cd "$COMPOSE_DIR"
docker compose exec -T webserver document_exporter "$EXPORT_DIR" -p
docker compose exec -T db pg_dump -U paperless paperless > "$DUMP_DIR/dump.sql"



restic backup "$DUMP_DIR" "$COMPOSE_DIR/export"

restic forget \
	--keep-daily 7 \
	--keep-weekly 4 \
	--keep-monthly 6 \
	--prune

rm -rf "$COMPOSE_DIR/export"/*
rm -rf "$DUMP_DIR"/*
