Technically, you should use drive image software (Ghost, True Image,
etc) to get an *exact* copy of your system. Copying files won't make an
exact duplicate.

You can tag xcopy so it only backs up files with the archive attribute,
if that's what you're thinking... /a or /m
(/m changes the attribute so it is no longer archive, /a preserves it)
> Is x copy possible in Win XP?
Yes, you can run xcopy in Win XP. It might not like giving you
permission to some files though.

There are many options that are up to you when you're copying the file.
Simply type xcopy /? at the command prompt, and you'll get something like:
Copies files and directory trees.
XCOPY source [destination] [/A | /M] [/D[:date]] [/P] [/S [/E]] [/V] [/W]
[/C] [/I] [/Q] [/F] [/L] [/G] [/H] [/R] [/T]
[/U]
[/K] [/N] [/O] [/X] [/Y] [/-Y] [/Z]
[/EXCLUDE:file1[+file2][+file3]...]
source Specifies the file(s) to copy.
destination Specifies the location and/or name of new files.
/A Copies only files with the archive attribute set,
doesn't change the attribute.
/M Copies only files with the archive attribute set,
turns off the archive attribute.
/D:m-d-y Copies files changed on or after the specified date.
If no date is given, copies only those files whose
source time is newer than the destination time.
/EXCLUDE:file1[+file2][+file3]...
Specifies a list of files containing strings. Each string
should be in a separate line in the files. When any of the
strings match any part of the absolute path of the file
to be
copied, that file will be excluded from being copied. For
example, specifying a string like \obj\ or .obj will exclude
all files underneath the directory obj or all files with the
.obj extension respectively.
/P Prompts you before creating each destination file.
/S Copies directories and subdirectories except empty ones.
/E Copies directories and subdirectories, including empty ones.
Same as /S /E. May be used to modify /T.
/V Verifies each new file.
/W Prompts you to press a key before copying.
/C Continues copying even if errors occur.
/I If destination does not exist and copying more than one
file,
assumes that destination must be a directory.
/Q Does not display file names while copying.
/F Displays full source and destination file names while
copying.
/L Displays files that would be copied.
/G Allows the copying of encrypted files to destination
that does
not support encryption.
/H Copies hidden and system files also.
/R Overwrites read-only files.
/T Creates directory structure, but does not copy files.
Does not
include empty directories or subdirectories. /T /E includes
empty directories and subdirectories.
/U Copies only files that already exist in destination.
/K Copies attributes. Normal Xcopy will reset read-only
attributes.
/N Copies using the generated short names.
/O Copies file ownership and ACL information.
/X Copies file audit settings (implies /O).
/Y Suppresses prompting to confirm you want to overwrite an
existing destination file.
/-Y Causes prompting to confirm you want to overwrite an
existing destination file.
/Z Copies networked files in restartable mode.
The switch /Y may be preset in the COPYCMD environment variable.
This may be overridden with /-Y on the command line.
I'd recommend, though that you use Ghost if you want to really clone a
drive as opposed to making backup copies of files.
