backup system

[erastus@connect]

Hi Guys,

I am suspecting a hard drive to be iffish.
I ran fsck on bot LogVol00 & /dev/md0
Got the system going.

I would like to create a backup of the system that I can restore on a new installation any ideas on this?

I am thinking on these lines tar -cvpzf backup.tar.gz --exclude=/backup.tar.gz --one-file-system /

Hello Erastus,

If you want to get a full copy of HDDs, then you'd better use rsync (at least), or even dd.

Thanks will use dd

Note, using dd in some cases might be dangerous, as it will overwrite superblocks on HDD.

Thanks,

But isnt it that dd writes onto a raw drive as well?

 

[zEitEr]

That really does not matter from what device to read and to what device to write, dd can do that. But if to write to HDD, then it might overwrite zeroblocks as well.
