-====== Rsync ======
-===== Simple exact copy =====
-Including all permisions, time, etc.
-  rsync -az --verbose --itemize-changes --times --recursive --whole-file --delete --links root@192.168.178.80:/source_dir/ /target_dir
-Notice the **'/'** behind the source_dir
-===== Output flags =====
-Each bit position and value in rsync's output:
-<code>
-  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")

-**Some example output from rsync for various scenarios:**
-<code>
-  >f+++++++++ some/dir/new-file.txt
-  .f....og..x some/dir/existing-file-with-changed-owner-and-group.txt
-  .f........x some/dir/existing-file-with-changed-unnamed-attribute.txt
-  >f...p....x some/dir/existing-file-with-changed-permissions.txt
-  >f..t..g..x some/dir/existing-file-with-changed-time-and-group.txt
-  >f.s......x some/dir/existing-file-with-changed-size.txt
-  >f.st.....x some/dir/existing-file-with-changed-size-and-time-stamp.txt
-  cd+++++++++ some/dir/new-directory/
-  .d....og... some/dir/existing-directory-with-changed-owner-and-group/

-====== Full backup ======
-<code>
-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.
