     7  ## rclone sync
     8  
     9  Make source and dest identical, modifying destination only.
    10  
    11  ### Synopsis
    12  
    13  
    14  Sync the source to the destination, changing the destination
    15  only.  Doesn't transfer unchanged files, testing by size and
    16  modification time or MD5SUM.  Destination is updated to match
    17  source, including deleting files if necessary.
    18  
    19  **Important**: Since this can cause data loss, test first with the
    20  `--dry-run` flag to see exactly what would be copied and deleted.
    21  
    22  Note that files in the destination won't be deleted if there were any
    23  errors at any point.
    24  
    25  It is always the contents of the directory that is synced, not the
    26  directory so when source:path is a directory, it's the contents of
    27  source:path that are copied, not the directory name and contents.  See
    28  extended explanation in the `copy` command above if unsure.
    29  
    30  If dest:path doesn't exist, it is created and the source:path contents
    31  go there.
    32  
    33  **Note**: Use the `-P`/`--progress` flag to view real-time transfer statistics
