Partimage, I'm confused


If I use partimage to make an image of my root partition, then later restore that image (possibly to a different hard drive), would the restore be bootable?

The answer is a qualified yes provided that the details for fstab are identical. If you image a drive (partition) then it is an absolute replica of the original. If you took the image from /dev/hda1 and restored it to /dev/hda1 then there would be no problem. If you restored it to /dev/hda3 then it would not work since fstab is pointed to /dev/hda1. You would then have to use something like knoppix to go and edit fstab to get all the mounts correct.

Yes, the partition will be bootable, but the drive may not be. It depends on what you do to the drive in the meanwhile. Specifically, the first sector or so holds the master boot record and parition table. If these get altered (if, say, the drive gets formated) then they would need to be rewritten before the computer will boot.

The following is the basic command to back them up and restore them. You will need to make sure how much needs to be backed up though (I'm guessing just the first sector)

to backup:
dd if=/dev/hda of=MyBackupFile bs=512 count=1

to restore:
dd if=MyBackupFile of=/dev/hda bs=512 count=1

In other words, disk dump from the primary master hard drive (hda, notice no number trailing) into a file; transfer 512 bytes at a time, 1 time. If I'm wrong on the size you may not get everything, so be aware...

On the other hand, if you do nothing to alter the MBR etc, then yes, the partition will boot just fine. If you ever lose the MBR, then there are places in this forum where you can get help.
