Hi,
maybe this question sounds a little bit stupid. Let me explain a little bit concerning the background.
I am backing up our spectrometers using IBMs TSM. That's perfect as long you need simple files only to restore.
Recently I tried a bare metal restore of a hole hard disk. Fortunately the reason was no hard disk crash
but the attempt to change a hard disk into a SSD. Nothing easier than that task. Simply install a Base system
and restore everything.
Unfortunately this calculation was made not taking into account the new GPT partition system of hard
disks. At least the boot partition gets a unique UUID and you cannot overwrite that UUID without destroying
Everything.
IBM created a red book describing a true bare metal restore using a Linux environment. Its not really
Trivial. The experienced authors needed 3 hours for a simple bare metal restore, so for unexperienced
people ...
Of course its possible to restore the spectrometer computer from the scratch and get all necessary files
>From the backup later. Very time consuming as well.
So, whats your method? I strongly think about the introduction of Hardware RAID Arrays.
Greetings
Rainer
