Basically, if you know how you would restore with tar, you can do the 
same with the BackupPC_tarCreate output.

I don't know how to automate it, but I'm sure it would be possible if 
you had an alternate boot and could tweak the default grub setting to 
flip to it, make the copy, then flip back.  Doing it manually you can 
just boot from CD or USB disk, connect to the image storage location via 
nfs, smb, or ssh, and do a whole-disk save.  The corresponding restore 
will create the matching filesystems and fix grub for you.  I'm not sure 
it is worth the trouble on Linux where you can work with the tar output, 
but it is handy to get a windows system back to a point where backuppc 
works again - and it is fairly fast since it only saves the used 
portions of the disk.
