You're batch file looks quite effective, well done!

My only comment is that the operations involve a large number of
copy and move operations on the full data set or zip file. Since
this involves around 600Mb (depending on compression ratio) being
moved around 6 times each loop, I think I'd use a utility other
than xxcopy to manage the file naming scheme.

This utility only has to get the date and increment a counter and
you could reduce the operation to 2 copies instead of 6 using the
same naming scheme! There are plenty of utilities that can do this.
The venerable STRINGS.COM or M.EXE
ftp://ftp.externet.hu/pub/mirror/sac/utiltask/m403.zip

Here's what I would do (ignoring how you get the date and counter).

Carry out your first xxcopy command to the ref directory as you've
done but add file logging with /Fo:filelist.txt/FML. This will be
used by wzzip as an input file list.

Then xxcopy the non-zero length files from the ref directory to
a temp directory but with /TR:0. Then copy back from the temp
directory to the ref directory using /RCY. The effect of these
2 steps is to set the filelength of the previously copied src
files in the ref directory to zero. Since this only creates the
directory structures but doesn't copy any data, it has a low
overhead.

Now issue your wzzip command using @filelist.txt as the source
file list and the previously determined date and sequence number
as your zip file name. This can be created directly to the burn_cd
directory by excluding *.zip files in the wzzip command.

And that would be it. 1 copy to the ref directory and one copy
by the wzzip command.
