backup of the whole hd

[Tamas K Papp <tpapp@Princeton.EDU>]

Hi,

Looks like my Powerbook has some hardware problem so I have to ship it
to Apple for repair.  Before that, I think it would be prudent to make
a backup --- could people please suggest some tools for that?  

I have a dual boot system, so I want to make a complete backup of the
whole hd.

tpapp:~# fdisk -l /dev/hda
/dev/hda
        #                    type name                  length   base      ( size )  system
/dev/hda1     Apple_partition_map Apple                     63 @ 1         ( 31.5k)  Partition map
/dev/hda2         Apple_Bootstrap untitled                3907 @ 64        (  1.9M)  NewWorld bootblock
/dev/hda3               Apple_HFS Apple_HFS_Untitled_2  30457793 @ 262208    ( 14.5G)  HFS
/dev/hda4         Apple_UNIX_SVR2 swap                 1000001 @ 30720001  (488.3M)  Linux swap
/dev/hda5         Apple_UNIX_SVR2 untitled            85490238 @ 31720002  ( 40.8G)  Linux native
/dev/hda6              Apple_Free Extra                 258237 @ 3971      (126.1M)  Free space

Block size=512, Number of Blocks=117210240
DeviceType=0x0, DeviceId=0x0

I can make the backup to an external hd, which has a bootable OS X
partition, so I can restore/backup from either linux or OS X.  I would
also like to verify the backup.

Thanks,

Tamas
