If you use the archive host approach to copying backups out of backuppc, 
it is up to you to label and be able to find them.  At that point they 
are basically a gnu tar copy that doesn't need backuppc to restore. And 
it doesn't have a week's history, it has the lastest run (merging 
incrementals with the previous full if necessary).

Normally, backuppc is mostly used for the online copy it makes in its 
own format and knows how to restore, so you just give it a big raid for 
storage and leave it alone.  There are a variety of ways to deal with 
getting offsite copies, none particularly good.  One approach is to 
image-copy the filesystem or the equivalent with raid-mirroring, then 
swapping a disk out.  Another is to use an external disk as the backuppc 
storage, swapping periodically and simply letting the next run catch up. 
  Or, if you have enough bandwidth to another location you can run an 
independent copy there.
