Why bother backing up the entire disk/partition?
The only thing that is important is you data.
For instance, it will most likely take you _longer_ to get you OS back off
- tape, disk, whatever - than it would to nuke the entire system & restore
I would backup :
3. parts of /var & /opt
And thats it. In this day of "broadband", you can easily get back updated
in notime. And even without "broadband", you could backup your update
packages to CD or something.
You backup "app" could be a simple tar command. It all depends on the
environment - I imagine this is for personal data.
