Luckily, restoring is not something i've had to do too often so I don't have a pre-written script for doing it but after booting from the CD and dropping to a shell I would use something along the lines of
--- BEGIN --- mount /dev/wd0a /mnt cd /mnt gzcat /scratch/backup/root.dump.gz | restore -r -f - cd /mnt/home gzcat /scratch/backup/home.dump.gz | restore -r -f - cd /mnt/var gzcat /scratch/backup/var.dump.gz | restore -r -f - cd /mnt/cvs gzcat /scratch/backup/cvs.dump.gz | restore -r -f - /usr/mdec/installboot /usr/mdec/boot /usr/mdec/biosboot wd0 --- END --- These are pretty much from memory so they may not be exactly right. Also if you boot from a CD you may need to remount /tmp somewhere so that restore has enough space to work. The added complication in my particular case is that everything other than / is located on a ccd(4) disk and the ccd driver is not in the RAMDISK kernel. Can't recall how I got round this last time but I do remember it causing me a few problems initially. Hope this helps - Simon --- "Will H.
