"smartest" way to do backups .. assuming you want to protect your data
a) if your data is on /dev/hda ... than backup to another disk on another
PC -- never backup to the same disk
- if the disk dies, you lose both main and backup stuff
- if your system goes down, you might not be able to boot
off /dev/hda7 if your MBR went bonkers
b) cp /etc/lilo.conf /etc/lilo.backup.conf
c) you can copy everyging from /dev/hda3 to /dev/hda7 but why ??
"debian setup/files" is already backed up millions of times
on the web
d) you only want to backup your pkg config, /etc and "/home"
to save your "important data"
root# mount /dev/hda7 /mnt/backup
root# tar cf - /etc /home | ( cd /mnt/backup ; tar xvfp - )
( but you should backup only the changes )
root# umount /mnt/backup ( important )
