All,
Just thought I'd throw my $0.02 in ...

Although not "one-click" rdiff-backup has worked well for me for Linux
bare-metal restores (both test cases and real dead machine, disk,
whatever, cases). I create a rdiff-backup backup of each partition or
major data area (typically root, boot, home, and public which may or may
not be separate partitions). I do copy the boot sector via 'dd' but
rarely use it. To restore to a new machine/drive I boot it with a
Debian Live DVD (or USB stick or whatever), restore root and boot,
reboot with a GRUB rescue CD and boot the restored root system in single
user as 'root', restore everything else, and finally install GRUB in the
MBR. One tip though. I backup root and boot with
--preserve-numerical-ids because the user/group mappings are invariably
different on the Live DVD.
Windows is a whole different can of worms, sadly.

This is what I have to do with Windows machines/partitions. I've tried
using rdiff-backup to back up Windows partitions but on restore the
permissions/ACLs are wrong. (I posted about this a long time ago but,
obviously, the issue was never resolved). So instead, I image the
partitions (I use ntfs-clone from the ntfs-3g package for NTFS, and
partimage for FAT, but whatever ...) then backup the _images_ with
rdiff-backup. Typically the rdiff-backup increments are about 10% of
the size of the space _in_use_ on the partition. Have only done
restores on machines that dual boot with GRUB though. No idea if it'd
work with a "pure" Windows machine.
So, yes, it takes some work but once I got the procedure down it's not
bad. The typing time is nothing compared to the actual restore time.
And the space savings using rdiff-backup vs. other tools makes it well
worth it to me. Of course, as always, YMMV.
Cheers
