I don't consider a copy stored on the same host where a simple
hardware, software or operator error could wipe everything at once to
be a real backup.  But it's better than nothing for the more likely
case of your main disk failing.

That's a better way to go if you have a 2nd machine to do the work.
However, backuppc would work just fine with a fairly default install,
even running rsync over ssh to itself over the network.   I'd do it
that way myself just to avoid creating a special case.  There might be
a more efficient approach but all that really matters is that it will
complete in a reasonable amount of time.

But, note that while backuppc will give you a nice method to restore
older versions of a few files or directories, and it can store more
copies in less space than about anything else, it won't be a great way
to restore the OS or its own working parts on the host machine.   That
is, the storage format is compressed and you'll need a working
instance of backuppc to restore from it.
