add beamup-sync for backup and restore

[dexter21767-dev]

Will add a better description later.

here's a docker-compose.yaml to create ftp/s3 servers for testing (i couldn't get the rsync server to work)

services:
  ftp:
      container_name: ftp-server
      image: garethflowers/ftp-server
      environment:
        - FTP_USER=beamup
        - FTP_PASS=test
      restart: always
      ports:
        - '20-21:20-21/tcp'
        - '40000-40009:40000-40009/tcp'
      volumes:
          - ./ftp:/home/beamup
  rsync:
    container_name: rsync-server
    image: mickaelperrin/rsync-server
    environment:
      - USERNAME=beamup
      - PASSWORD=testtest
      - VOLUME_PATH=/data
      - VOLUME_NAME=data
      - HOSTS_ALLOW=0.0.0.0/0
    ports:
      - '873:873/tcp'
    restart: always
    volumes:
      - ./rsync:/data
  s3:
    container_name: s3-server
    image: minio/minio:RELEASE.2023-11-01T01-57-10Z-cpuv1
    command: minio server /data
    ports:
      - "9000:9000"
    environment:
      MINIO_ROOT_USER: beamup
      MINIO_ROOT_PASSWORD: test1234
      MINIO_DOMAIN: s3.amazonaws.com
      MINIO_DEFAULT_BUCKETS: my-bucket
