  $ rclone lsd caringo:

• Copy your Pictures directory (recursively) to a "old-pics" bucket. It will be created if it does not exist.
  

  $ rclone copy --s3-upload-concurrency 10 --s3-chunk-size 100M '/Volumes/Backup/Pictures/' caringo:old-pics

• List the files in the bucket
  

  $ rclone ls caringo:old-pics
       6148 .DS_Store

    ...

• Quickly see the size of the objects in a bucket:
  

  $ rclone size jam:old-pics
  Total objects: 173
  Total size: 9.550 GBytes (10254108727 Bytes)

• Verify all files were uploaded (note trailing slash is necessary on local directory!). The check command can also compare two buckets.
  

  $ rclone check ~/Pictures/test/ jamcaringo:old-pics

  Note that "check" appears to be confused by the Mac OS X hidden directory ".DS_Store".

• Tips: use "-v" and "--dump headers" or "--dump bodies" to see verbose details. 
• To ignore system files you don't want compared or uploaded use something like:
     --excludes '.DS_Store' --exclude '.Trashes**' --exclude '.fseventsd**' --exclude '.Spotlight**' --exclude '._*'
• Increase the part size with --s3-chunk-size 100M (defaults to 5M) to improve the speed and storage efficiency of resulting large streams. 
• Speed up large transfers with "--transfers=10" and "--s3-upload-concurrency 4".
• You might want to use --s3-disable-checksum when uploading huge files.
• Unfortunately rclone does not copy or let you add metadata, though there are some enhancement requests on github.
• Copy a file from a plain http website into Swarm by streaming it directly:
  

  # rclone -v --dump headers copy commondatastorage:gtv-videos-bucket/sample/ElephantsDream.mp4 /tmp/
  [commondatastorage]
  type = http
