Ingres r3 checkpoint with zip

Hi

I have read some articles about doing checkpoint (backup) on Windows
Ingres r3.

In order to compress the checkpoint like unix, we have to do similar
things like

WSDD cd %D; /bin/tar cf - . | /usr/bin/compress > %A

I have downloaded the pkzipc.exe from a company.

And how should I change the following original lines

WSDD ckxcopy "%D" "%A" BACKUP
WRDD ckxcopy "%D" "%A" RESTORE

Thanks
Norm
