Martin,

I have a similar backup scheme that runs everyday using XXCOPY, WZZIP
(WinZip's command-line program), and optionally WMFREN a command-line
program that can rename with more than 8 characters. The WinZip and 
system date parts of this scheme (to give proper credit) were 
inspired by Fred Langa's personal backup strategy.

1. XXCOPY copies files to a temp folder.

2. WZZIP moves the files into an archive named ".zip".

3. File renamed by WMFREN or XXCOPY depending on the technique 
used. If WMFREN is used ".zip" will be renamed in place, ex. 02-12-
11.zip. Folder and files are turned into an "object" that 
XXCOPY deletes at the /db# age you specify.

4. If XXCOPY is used, the ".zip" is moved into a macro dated 
folder and then moved again using /SL, /SX, or /SR which synthesizes 
the dated folder into the filename, ex. 02-12-11`.zip using /sl for 
this one.

1st method (xxcopy, wzzip & wmfren)
----------------------------------------------------------
@echo off
XXCOPY C:\ G:\temp\ /da#0/s/r/h/pb/yy

wzzip -m -u -ex -r -P g:\temp\.zip g:\temp\*
wmfren g:\temp\.zip g:\temp\C$YE:4-$MO-$DA.zip

XXCOPY G:\Backups\*.zip /db#10/rsy/ed/pd0/y
XXCOPY G:\temp\*.zip G:\Backups\ /rcy/ed/pd0/pb/y
----------------------------------------------------------

2nd method (xxcopy & wzzip)
----------------------------------------------------------
@echo off
XXCOPY C:\ G:\temp\ /da#0/s/r/h/pb/yy

wzzip -m -u -ex -r -P g:\temp\.zip g:\temp\*

XXCOPY G:\temp\*.zip G:\temp\C/$YY-MM-DD$\ /rcy/ed/pd0/pb/y
XXCOPY G:\temp\*\*.zip G:\Backups\ /sl/pb/yy
XXCOPY G:\Backups\*.zip /db#10/rsy/ed/pd0/y
XXCOPY G:\temp\*\*.zip /rsy/ed1/pd0/pb/y
----------------------------------------------------------
