Each bit position and value in rsync's output:

  YXcstpoguax  path/to/file
  |||||||||||
  ||||||||||╰- x: The extended attribute information changed
  |||||||||╰-- a: The ACL information changed
  ||||||||╰--- u: The u slot is reserved for future use
  |||||||╰---- g: Group is different
  ||||||╰----- o: Owner is different
  |||||╰------ p: Permission are different
  ||||╰------- t: Modification time is different
  |||╰-------- s: Size is different
  ||╰--------- c: Different checksum (for regular files), or
  ||              changed value (for symlinks, devices, and special files)
  ||
  |╰---------- the file type:
  |            f: for a file,
  |            d: for a directory,
  |            L: for a symlink,
  |            D: for a device,
  |            S: for a special file (e.g. named sockets and fifos)
  |
  ╰----------- the type of update being done::
               <: file is being transferred to the remote host (sent)
               >: file is being transferred to the local host (received)
               c: local change/creation for the item, such as:
                  - the creation of a directory
                  - the changing of a symlink,
                  - etc.
               h: the item is a hard link to another item (requires
                  --hard-links).
               .: the item is not being updated (though it might have
                  attributes that are being modified)
               *: means that the rest of the itemized-output area contains
                  a message (e.g. "deleting")

rsync -haxAX --stats --delete --info=progress2 --info=name0 /* "$TargetMnt" --exclude={/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/lost+found}

Some notable comments about parameters:

    --stats gives information on files added, changed and deleted from the clone (called backup in your case).
    --delete instructs rsync to delete files in the clone that no longer exist in the source directory.
    info=progress2 gives a modern looking progress display whilst cloning directories.
    --info=name0 prevents every single filename from being displayed as it is being copied. This gives less screen clutter but you may want to omit this parameter.
    /* tells rsync where to start synchronizing files. In this example it's the root directory but you want to change it to /media/user1/DATA4/FolderA.
    "$TargetMnt" tells rscync where to clone to. In your case change it to "/media/ivan/Seagate Backup Plus Drive/FolderA". The double quotes are important because your directory names contain spaces in them.
    The second line starting with --exclude={/dev/* you don't need at all because these directories aren't in the list. Don't use this line and drop the line continuation character \ at the end of the first line.

As with all backup scenarios always test the backups to make sure all files are there and contain the appropriate information.
