You might take a look at rsnapshot, then.  It uses hard links to avoid
backing up the same file more than once, but everything ends up in its
own directory that you can see and manipulate with standard tools.

Backuppc does put everything together where you can see it, but it does
so by using its web interface or command line tools that are specific to
backuppc.  

I understand you have a lot of storage space.  But the less space your
backups take up, the more backups you can have.  I keep daily backups
for x number of days, weekly backups for y days, yearly backups for z
days.  All of this for multiple machines.

Another benefit of not backing up the same files over and over again is
that you can perform backups over the internet to an offsite location,
and it doesn't require as much bandwidth.

But it is hard to argue against sticking with the tried and true
"ancient tools".

Yeah, you gotta test...  But for my Linux systems I usually don't worry
about backing up the OS.  I keep install media handy and if I have a
disaster, I reinstall the OS and then restore my data and certain things
in /etc.  But that is a more manual process than just restoring the
whole thing at once.
