Thanks.... this is an experimental box and not a production server. We are
testing this type of backup in addition to tapes....

On Win2K machines, a full backup/verify to hard disk will do 5GB in about
20 mins or less. The restore has been flawless & everything works. This is
faster that tapes, but only intended to be in addition.... we use mirrors too.

I have found that all kinds of backups can be made, but the question is:
will they restore correctly...
