Win2K and Automated ERD’s

I want to run automated ERD’s on some windows 2K machines, and I have run into a few problems, so I have a couple of questions:

1. Is a system state backup better that an ERD or is it the same?

2. Does anyone know how to do a silent ERD likein NT with the “rdisk /s-“?

I know that W2K has ntbackup to handle Sch. backups but it doesn’t seem to have the ability to do ERD’s.

B.T.W. The goal here is to have a batch file that makes an “ERD” on the Hard drive and then copy if off to theserver, for it can get backed-up nightly.
Thanks in advance
