I have been wondering about something similar for some time. Can one make a complete backup to tape of a hard disk partition using Lenny's Boot Floppy kernal with the tape driver. I would like to back my whole hard disk to tape, and be able to restore the whole thing to a blank formated disk. I would like to skip loading the Foundation Set, etc. I think this should be possible, but since I have only used my tape drive from the UA I am not really sure how to go about this. I think that something like the following should do the trick, but would like to post it here so I can be sure. I would hate to think I had a good backup and be SOL. From a floppy file system after boot using the floppy tape kernal #mount /dev/rfp002 /mnta -r #find /mnta -print | sort | cpio -ocB | dbuf -oT512 > /dev/rft3 Does this make any sense? Please correct me if I am wrong.
