The simplest one is to copy the whole source volume into its
backup volume (one source volume --> one destination volume).

xxcopy c:\ d:\ /BACKUP

This command performs a full backup at first. And, you
can use the same command which will perform an incremental
backup by skipping the files whose timestamp and size
matches exactly to the one in the destination. This is
a safe backup method, but the destination volume will
eventually filled up with obsolete files because nothing
is deleted in this method.

So, to make an exact copy of the source volume to the
destination, use the following command:

xxcopy c:\ d:\ /CLONE

This is a variation to the first one which deletes
files or directory in the destination that are
no longer present in the source. Since this operation
involves deletion, you need to be alert (there will be
confirmation prompts for deletion which should be
suppressed for batch-file operation).

In the both cases, the source and/or destination
does not have to be the entire volume (the root
directory) but could be a subdirectory.

The more general formula is

xxcopy \source_directory\ \destination_dir\ /CLONE

You may use UNC naming for source and/or destination,

xxcopy \\serverA\c\ d:\backup\serverA\c\ /clone

Since XXCOPY handles only one directory at a time, you
may create a batch file to do more:

mybatch1.bat
-----------------------------------------------------
xxcopy \\serverA\c\ d:\backup\serverA\c\ /clone
xxcopy \\serverA\d\ d:\backup\serverA\d\ /clone
xxcopy \\serverB\c\ d:\backup\serverB\c\ /clone
-----------------------------------------------------

There are lots of variations:

You may want to reduce the network load by adding a /NI
switch.

xxcopy \\serverA\c\ \dst\ /clone /NI:5

(Play with the value for an optimum result --- larger the
number the more pause between file-copy).

Once you create a batch file, you may place it in the
scheduled tasks for automation.

you should download the help file and make it handy.

Other experienced members in this group may give you a
lot more specific help (when you create your own batch
file, you may post it here for critiquing).
