Kan,

In Message No. 2 of XXCOPY Digest 675, Denis Green asked whether
XXCOPY could be used to make incremental backups to a Read Only CD
(CD-R). In your answer in Message 3 of the same Digest, you made a
good reply about the differsnce between the /CLONE and /BACKUP
switches, but I don not believe you addressed the question about
using XXCOPY to backup to CD-R media. I use Nero 5 and I have
not found any way to use XXCOPY to backup directly to CD-R.
In the Nero documentation, all references to writing to CD-R that
I can find call for using the Nero program to make compilations
to write to CD-R.

Is there a way to use XXCOPY to backup directly to CD-R?

On the other hand, I use XXCOPY to backup selected folders to
formatted CD-RW frequently and it works quite well. I use several
batch files that I have written to automate the backups for
several different sets of folders.

Recently I wanted to clone a CD-RW to another CD-RW disc using
XXCOPY. The target CD-RW had been used to back up the same folders
and when I started the backup. I received an error message saying
that there was not enough room on the target CD-RW for the
operation. In the source CD-RW many, many files had been
deleted, so there should have been room for the clone operation.

My solution was to write a batch file like this in order to delete
files on the destination CD-RW that would be overwritten or deleted
by the /CLONE operstion before starting the copying operation:


REM This portion clones CD M: with deletions to L:\
REM
REM The first line below deletes files and folders on the
REM destination CD-RW that are either not in the source or else
REM qualify for being overwritten
REM
REM NOTE: The deletion command looks backwards, but it is correct
REM to delete files on L:\ !!!!!
REM
E:\XXCOPY\XXCOPY.exe /RS/BU/FF/YY L:\* M:\
E:\XXCOPY\XXCOPY.exe /EC/WS/BU/FF/NX0/YY M:\* L:\

This batch file seems to do the trick. Do you have any suggestions
for a better way to do this?

I am using XXCOPY Pro version 2.84.0 on WIN98 2nd edition.
