[lug] Backup

[Siegfried Heintze]

Can anyone comment on booting a stand alone linux like knoppix to restore a
windows partition?  I hope to try out Mondo/Mindi rescue. I believe they
will restore linux and windows partitions from a local DVD. I wonder if
there is some software like Mondo/Mindi rescue that can restore a windows
partition across a network?

I just boot from a knoppix cd, setup the network by hand
(iwconfig/ifconfig/route/resolv.conf, unless you have a router with DHCP
setup, in which case there's no setup for Knoppix), partition, mke2fs, then
use rsync or rdiff-backup to restore.  Then setup /boot/grub/menu.lst and
run
grub-install on the boot drive.  (Or you could use lilo, but why??)

Can't comment on the Windows aspect of it much, since I last used Windows in
1999.  I do remember that back then, it was very difficult to just copy the
files over and have a working Windows system.  The Windows backup program
that
came with Windows 98 expected you to install Windows, *then* run the
restore.
That program failing me 3 times out of 3 was part of what spurred me to
learn
Linux.  Once I realized what I could do with Linux, I erased Windows from
all
my computers, and haven't put it back since.  I hope to never again know
more
about Windows than the average office worker.

I've done this for diskless Linux clusters, and it works well but there's
definitely an investment in learning how to do this.  You probably don't
want
to learn how to do this unless you want to run diskless machines.

I have cloned many Thinkpad 600Es using the simple method I described above,
and cloning is the same thing as a backup restore, so I know it works and is
easy too.
