rclone: copy only files changed in the last 24 hours

See the [--no-traverse](/docs/#no-traverse) option for controlling
whether rclone lists the destination directory or not.  Supplying this
option when copying a small number of files into a large destination
can speed transfers up greatly.

For example, if you have many files in /path/to/src but only a few of
them change every day, you can to copy all the files which have
changed recently very efficiently like this:

    rclone copy --max-age 24h --no-traverse /source/path/ azure:64gb -P

**Note**: Use the `-P`/`--progress` flag to view real-time transfer statistics

Usage:
  rclone copy source:path dest:path [flags]

Flags:
      --create-empty-src-dirs   Create empty source dirs on destination after co
py
  -h, --help                    help for copy
