Backup NICHT mit dd

Aus irgendeinem #$@%&!-Grund geht partimage auf meinem eeepc nicht, meldet jeweils beim *Erstellen* des Images: "image Lesefehler Bitmap block 0".

Hab allerdings diesen Beitrag gefunden:

dd usually the *ABSOLUTELY WRONG* tool to use for pushing around file
systems, since you have to issue the "count" command to cut off the dd
at the end of the partition absolutely correctly or you will leave off
the last few bits of your partition and filesystem, or start copying the
*next* partition and filesystem. It also guarantees you a dd image
exactly the size of the partition on disk instead of the size of the
file system, which may be *vastly* smaller and thus much easier to save
and faster to write.

Wie dem auch sei, man kann ja immer noch mit dd images erstellen,(hoffe ich).
Hier ne Anleitung:
http://www.debianhelp.co.uk/ddcommand.htm

full hard disk copy

dd if=/dev/hdx of=/dev/hdy
dd if=/dev/hdx of=/path/to/image
dd if=/dev/hdx | gzip > /path/to/image.gz

Hdx could be hda, hdb etc. In the second example gzip is used to compress the image if it is really just a backup.

Restore Backup of hard disk copy

dd if=/path/to/image of=/dev/hdx

gzip -dc /path/to/image.gz | dd of=/dev/hdx

MBR backup

In order to backup only the first few bytes containing the MBR and the partition table you can use dd as well.

dd if=/dev/hdx of=/path/to/image count=1 bs=512

MBR restore

dd if=/path/to/image of=/dev/hdx

Add "count=1 bs=446" to exclude the partition table from being written to disk. You can manually restore the table.
