Backup Hard Disk Drive
Using dd to back up and restore disk partitions and even whole disks
dd if=/dev/hda1 of=/hdimage.raw
will pull the first partion of the first drive (normal windows drive C:) into a file /hdimage.raw
dd if=/dev/hda2 of=/hdimage.raw
will pull the second partion of the first drive.
dd if=/dev/hda3 of=/hdimage.raw
will pull the third partion of the first drive.
dd if=/dev/hdb1 of=/hdimage.raw
will pull the first partion of the second drive.
dd if=/dev/hdb2 of=/hdimage.raw
will pull the second partion of the second drive.
bigger better uncut:
dd if=/dev/hda of=/hdfullimage.raw
will pull total drive with boot MBR included
other methods.
growisofs uses dd to burn direct to DVD
growisofs -Z /dev/dvd=/dev/hda
will burn the first 4.7GiB of the first drive directly to DVD in raw format.
this does back up full HD including MBR, hidden Windows storage & unused cruff. The resulting disk image is restored.
after DVD is burned the HD image is restored with
dd if=/dev/dvd of=/dev/hda
Simple as can be, now package a nice complicated GUI around it and sell it for big bucks!!
One minor flaw and its all my fault. If you backup
WinXP then upgrade your LAN & DVD firmware, install new video card. and then hopelessly screwup your windows install. Do not reuse earlier backup, I did and it force a 3 day only forced re-activate of my windows machine, so I am hosed for about three months (I reinstalled it two months-ago). Lession learned [b]firmware upgrades changes[/b] the way the hardware reports to windows. Puppy rules badly hosed puppy is only a mv command and reboot away 2 minutes max!
