DVD burning for backups on Windows XP

I had to recreate Synop’s DVD backup burning capabilities today. After some searching and digging around I’m using:

• cdrtools: Using mkisofs.exe we can create DVD ISO images greater than 2GB from the command line. This seems to be a project that stalled and has been carried on by others. In the end I found good information on the CDR Tools Front End site, which points to the latest unofficial versions on a German site.
• Windows Resource Tools: From Microsoft, these tools include dvdburn.exe for burning the actual disks.

Here’s a quick sample backup script that we use:

del "E:\backup\burning\FridayA.iso"
del "E:\backup\burning\FridayB.iso"
"C:\Program Files\cdrtools\mkisofs.exe" -v -J -R E:\backup\burning\FridayA\ > E:\backup\burning\FridayA.iso
"C:\Program Files\cdrtools\mkisofs.exe" -v -J -R E:\Backup\burning\FridayB\ > E:\backup\burning\FridayB.iso
"C:\Program Files\Windows Resource Kits\Tools\dvdburn.exe" D: e:\backup\burning\FridayA.iso
"C:\Program Files\Windows Resource Kits\Tools\dvdburn.exe" H: e:\backup\burning\FridayB.iso
"C:\Program Files\cdrtools\open_cd.exe" d
"C:\Program Files\cdrtools\open_cd.exe" h
