What I and at least a few others here do for offsite backups is to use a 
raid 1 mirror to duplicate the disk containing the BackupPC data directory.

I have a 3-way mirror with one of the elements being a hot-swap drive 
enclosure.  Once a month, I pull the drive, send it offsite, and replace 
it with another drive (new or rotated back from offsite).  The third 
drive allows me to maintain redundancy while swapping and re-syncing the 
removable drive.  If I need to restore something from one of those 
backups, I just retrieve the drive and temporarily replace the current 
drives for log enough to do the restore.

Actually, I have the OS and all the data on a single mirrored set of 
drives, so when I retrieve the old drive, I can just boot it up and I 
have the full backup server ready to go with all of the old backups 
available.

Don't know if this is workable for you, but it is another option to get 
offsite archival backups.

If you do it this way, just make sure not to let it start any backups 
while you are doing the restore.
