I'm not to sure it would work because windows xp uses a NTFS filesystem. if your useing the offical knoppix then there is no safe way to write a ntfs file (thats more of a problem when restoring really.)
I just started using the Knoppix CD yesterday. (It's actually the first deb-based distro I've tried.)
I'd like to use to it back up a WinXP machine. My intent is to just boot and dd the whole HDD to an NFS share on a mirrored Sun machine. That way I get the whole MBR and everything. I don't care much about how long it takes, just as long as it works. I figure I finally have the XP install all tweaked and tuned the way I want it and have all the apps I need installed and registered, so I should grab an entire image while it's still good. Over time, the system will probably get broken, distorted, or infected, and restoring an image using Knoppix is a lot simpler than reinstalling. It'll even let me keep my XP activation that way.
Is this a good idea? Is it a bad idea? I've never heard of anyone doing anything similar. Is there anything I should take into consideration (besides needing a HUGE storage volume)?

That's why I'm thinking the dd utility would be a good way to do it. dd is like rawrite.exe for windows. It records a raw bit-by-bit copy of the device without looking at blocks and filesystems. You don't even need to mount the desired volume to copy it.
--Instead of dd, see:
' apt-cache show partimage '
' man partimage '

Unless someone else can show me that DD works the same, I won't use anything else.
Just a little FYI.
oH DD is a raw writing utility? thats exactly what I have been looking for!
I had no idea. Now I can finally move my hardrive info to another bigger hardrive. (needed this because I'm useing a HP which has a recovery partition)
I have been using dd successfully, backing up a complete HD to an image file. It does not check any file sstem, just copies theraw data!
or cleaning out unused space and compressing itCode:dd if=/dev/hda of=/mnt/hdb1/hda.img bs=1M
I have also moved partitions from one HD to another this way, but it only works if the head count is the same![/code]Code:# For every partition x mount /dev/hdax dd if=/dev/zero of=/mnt/test/null.txt bs=1M ; rm -f /mnt/hda1/null.txt umount /mnt/test # Backup with compression dd if=/dev/hda bs=1M | gzip -9 -c > /mnt/hdb1/hda.img
Well, I finally found someone in this forum who backs up to an image file.
That is what I tried last week and NOW thanks to my own INCREDIBLE STUPIDITY
I need to restore my Knoppix partition from that file. (Long story. Let's not go there)
When I backed up the Knoppix partition I did:
dd if=/dev/hdb2 of=/mnt/hda6/hdb2.img
To get restore Knoppix to /dev/hdb2 I assume I need to
mount -t /dev/hda6/hdb2.img
first and then
"dd" back to the original /dev/hdb2 partition.
Any tips/tricks/caveats/advice before I attempt this?
Oh, I assume I should format the /dev/hdb2 partition first to start clean, right?
Thanks,

--You're on the right track, but you don't even need to mount the image file; just:
' time dd if=/mnt/hda6/hdb2.img of=/dev/hdb2 bs=10M '
--MAKE SURE /dev/hdb2 is unmounted **before** you do this!!
And there is no need to reformat 1st, because DD will return it to the exact same state it was in at the time of backup.
--Good luck, and keep backing up regularly.
