Fast compared to "build partitions, mount them, rsync from upstream
snapshot or copy tarball, run 'grub-install in chroot cage', reboot" ?
My first dump/restore experience goes back 25 years, and I always
found the "tower of hanoi" based system of backup tape number and
stacking to be quite burdensome. It used to be vital when tapes were
expensive and backup media small, but in these days of bulky external
drives, it seems quite pointless.

The rsnapshot style snapshots on a separate pile of disk is also very
fast to generate incremental updates for and can be much easier to
provide backup access to users for. Even if you need media based
backups, I'm personally going to be extremely surprised if modern
dump/restore is faster than tarball based backups such as AMANDA
provides.

Do you have any measurements to verify your claims of speed?
