backup van partitie tabel

[Sir Isaac]

Wat is de beste manier om een backup te maken van een partitie tabel?
Kun je bijvoorbeeld een backup maken met:

code:

dd if=/dev/hda of=/mnt/floppy/parttable bs=512 count=1

en die vervolgens herstellen door te starten van een live cd met:

code:

 dd if=/mnt/floppy/parttable of=/dev/hda

Of is er een mooie fdisk optie?

Een search op google op 'linux backup partition table' gaf loads of informatie om je partitie tabel te backuppen....bv met dd inderdaad...zoals hier.

Voor een mooie fdisk optie: 'man fdisk'.

dd if=/dev/hda of=/mnt/floppy/parttable bs=512 count=1

Dit zet niet je partitietabel op de diskette, maar de bootsector van je eerste vaste schijf. Partitietabel backupen kun je het beste gewoon met fdisk en een stukje papier doen. Er is trouwens al eens een topic hierover geweest, waar een wat meer geavanceerdere methode werd beschreven.

Dat is wel de partitietabel van /dev/hda hoor...
(En bootsect)

@XTerm: als je zoals Sir Isaac je partitietabel probeert te backupen, ga je echt de mist in hoor. Een klein deel van de partitietabel staat---naast de bootloader---inderdaad in de eerst 512 bytes van de bootsector. De rest van de partitietabel staat echter verder op. Zoals je ziet in de ruwe gegevens van fdisk begint mijn partitietabel op regel 0x1C0 van het eerste blok. Het gaat hier om partities 1, 2, 3 (alle 3 normale linux partities) en 4 als uitgebreide partitie. De logische partities staan echter in de daarop volgende blokken, namelijk partities 5, 6, 7, 8 (allen normale partities) en 9 als swap partitie.

Alleen de eerste 512 bytes van de vaste schijf kopieren is dus een slecht idee als je je partitietabel wilt bewaren.

[XTerm]

Heh, nooit over nagedacht

Heb het nooit gemerkt omdat ik in het slechtste geval altijd m'n eerste 512 bytes verwijderde...

* XTerm eens uitzoeken hoe het precies werkt

Jointm1k, jouw partitietabel begint (net als die van iedereen) op 0x1BE:

0x1BE: 80 01 01 00 83 FE 3F 01 3F 00 00 00 43 7D 00 00 /dev/hda1
0x1CE: 00 00 01 02 83 FE 3F 11 82 7D 00 00 10 EC 03 00 /dev/hda2
0x1DE: 00 00 01 12 83 FE FF FF 92 69 04 00 14 EB FF 00 /dev/hda3
0x1EE: 00 FE FF FF 05 FE FF FF A6 54 04 01 A7 8E C6 03 /dev/hda4
0x1FE: 55 AA (signature)

Die 0x80 op 0x1BE bijvoorbeeld waarvan bit 7 is geset, geeft daarmee aan dat in jouw geval /dev/hda1 de bootpartitie is...

Dat is wel de partitietabel van /dev/hda hoor...
(En bootsect)

Alleen de eerste 4 partities. De rest staan verspreid over de gehele disk.

Of is er een mooie fdisk optie?

Export :
sfdisk -d /dev/hdxx > hdxx.out

Import :
sdisk /dev/hdxx < hdxx.out

@ sepp.zutphen.nu: Wel, zo diep heb ik me er ook niet in verdiept. I stand corrected ^_^.
