I recommend having a read at the wiki

https://github.com/dani-garcia/vaultwarden/wiki/Backing-up-your-vault

I use the docker image bruceforce/bw_backup

My docker compose settings:

bw_backup:
  image: bruceforce/bw_backup
  container_name: bw_backup
  restart: unless-stopped
  init: true
  depends_on:
    - bitwarden
  volumes:
    - bitwarden-data:/data/
    - backup-data:/backup_folder/
    - /etc/timezone:/etc/timezone:ro
    - /etc/localtime:/etc/localtime:ro
  environment:
    - DB_FILE=/data/db.sqlite3
    - BACKUP_FILE=/backup_folder/bw_backup.sqlite3
      # EVERY DAY 5am
    - CRON_TIME=0 5 * * *
    - TIMESTAMP=false
    - UID=0
    - GID=0

Once I have the backup file I use borg backup al
