I'd stick to tar.

I prefer tape for whole-system backups. More capacity, relatively
inexpensive. CDs are just too small.

Helpful, possibly. Necessary? No. My last full backup missed two
files, with normal use, out of ten partitions / directories backed up.

Dunno.

- Replace disk.
- Install base Debian system.
- Recover package list from archive, set selections with:
$ dpkg --set-selections < package.list
- Update system with 'apt-get upgrade'.
- Restore /etc and other partitions from backups.
- Verify.
