[SWLUG] Taking a disk image

[Terry John]

Hi all,

 

I had a bit of a shock yesterday, when for a ghastly hour I thought I
was going to lose my entire installation.  OK, I have my data backed up,
but the thought of having to go back and install all the tools I've
installed and configured over the years was not making me happy (I'm
talking about things like Netbeans, Eclipse, subversion (no, it doesn't
work out of the box on a SUSE install), CASE tools, Zend and the Zend
Server that took me weeks to get working, Crossover Office and all the
various Windows bits I've installed with it under WINE, the OU VLE,
browser extensions, etc etc).

 

Does anyone know of a tool that will take an image of all my disk
partitions (Linux and Windows), and the MBR, so that I could - if I
wanted - just slap in a new HDD and write the image to it such that it
would then boot up and I'd be back to normal?

 

 

To do a disk image you can use dd. You can use it to back up your entire
disk or just to back up your 1st sector if you're nervous. I've done it
a couple of times when I've been doing upgrades though I've never had to
use the backup thankfully. I'd have to look up the syntax though

 

For normal backups I like to use 'dump' and it's best friend 'restore'.
You can back up directories or partitions etc.

 

Terry
