cloning a rh9

[scottRen]

how does one back up a linux server RH9 on to a bigger hardrive, i kinda want to "clone" the machine onto a new machine of identicle components with just a bigger hard drive, the machine is used for
mail server,ftp and web hosting

dd the partition to a file, and dd it back on the new HD, run resize2fs to resize it to its maximum size, and finally run fsck over it. Sorry that i cant provide an example dd line, i dunno.
Alternative is, simply cp -a (cp -Rdp) (-x) everything from the first to the second partition.

. Mac for productivity
.. Linux for developement
... Windows for solitaire

A slightly easier and commercial way is use Acronis TrueImage which can be run from a CDR or from Linux natively. Works just like ghost with a friendly front end. It will actively resize or keep the partition the same size during the restore process. You can also mount the image later as a logical drive to get a file or two. This way you have the upgrade and a snapshot backup to fallback on to.
