Is there some way to clone what I've got on this disk onto a
replacement? I don't really want to install everything from scratch.
man dd
Hm, what about 'cp -a'? I think this one is much better. Well, at least
in case, that disk aren't exactly the same, I guess.
The last time a discussion as such arose, I took some notes which I believed
I would find valuable one day. FWIW (apologies about authors not attributed

I second that, dd, man dd
boot sector: dd if=/dev/hdd0 of=bootsect.lnx size=512 count=1 (replace
hdd0 with drive name)
Entire drive:
dd if=/dev/hdd0 of=/some-location/hdd0.img (make sure file system is NOT
mounted, copy to a different file system!)
and theres also QTParted, you can find it on system rescue cd
(www.sysresccd.org)

I agree, dd. Great for linux,
dd if=/dev/hdax of=path/file.img bs=1024
How do we get the best performance over network with ethernet mtu?
you could also dd to several files such that each file will fit on CD.. or
even Zip them before puting them on cd.
anyone know if you can send dd output to gzip on the fly and have it stop
when the compressed image reaches 650MB or 4GB and start a new image? You
can obviously output a certain number of sectors with dd, but there's no way
to know the effective compression ratio of any given set of random files...
dd just doesn't work with windows xp because of certain Security IDs written
to the disk at the time of install which depend on hardware information.
Ghost is able to reproduce this.
Does anyone know of another product (for windows 'ghosting') with more of a
'free software' licensing attitude?

Hi there,
I have read a few howto's that involve using dd and having to reinstall
bootloaders, etc. We use Nortons Ghost (an older version)alot to copy
entire NTFS drives and partitions and they auto-magically boot.
Older version might be a problem but:

Watch for wrap.
I have
not yet found a solution to backup Linux ext2/3 drives in an easy
manner.
Newer versions of Ghost will do it, as above.
I wish to backup a drive on a Linux proxy server so that I can throw the
in spare drive within minutes of a drive failure and be up and running.
I don't wish to go the RAID route though.
Are there any boot CD's or complete softwares that can handle this?

It looks like there's a version of dd called "sdd" that's supposed to be
better.

Partimage could be your solution...? /Bengt
Looks great, but I don't see any disk-to-disk option in there. Is there
one?
