How to recover with a full backup?

Hi!

I'm making preparations for the case when I can no longer boot my machine, and I'm not able to recover with the GRUB recovery mode.

I have a full backup, which includes the system as well as personal data.

When I can't recover, I would install the system anew, from the Kubuntu installation ISO. Then I would unpack my backup, in some directory /backup. Now, how to get a running system again, from that? Could I just replace the top level directories with ones from the backup? Such as:

cd /
mv /bin bin.tmp
bin.tmp/mv backup/bin bin
rm -r bin.tmp

Now, how to make it bootable? Can I just do:

grub-install /dev/sda

Cheers,
Volker
