relative_path=$(realpath --relative-to="${site_root}" "${destination}")
++ realpath --relative-to=/mnt/farmer /mnt/farmer/4t4
realpath: /mnt/farmer/4t4: No such file or directory
+ relative_path=

  index: 3
  env:
    site_root: /mnt/farmer
    user: x9011
    host: 192.168.1.4
    rsync_port: 12000
    site: farmer
    options: --bwlimit=80000 --preallocate --remove-source-files --skip-compress plot --whole-file

but the /mnt/farmer/4t4 is exist in 192.168.1.4
