I also use Knoppix to do a bare metal restore of a CentOS 4 machine.
Here are our essential steps :
1) partition the disks (fdisk)
2) create raid (mdadm)
3) setup LVM (pvcreate, vgcreate, vgchange, lvcreate)
4) create filesystems (mke2fs, mkswap)
5) mount the filesystem
6) extract the backup from the backup server using a method like Carl
suggested
[EMAIL PROTECTED]:~$ /usr/share/backuppc/bin/BackupPC_tarCreate -h
client.example.tld -n -1 -s / / |gzip -1 |nc client.example.tld 8888
[EMAIL PROTECTED]:/mnt/targetdisk# nc -l -p 8888 | tar xzvp
7) restore ACLs since backuppc doesn't handle those (setfacl --restore)
(we use a cronjob to backup the ACLs with getfacl)
