I assume you still want your traditional backups but just want
additional offsite backup as well?

I think you want to use BackupPC_tarCreate[1]. It will create a tar
archive but it sends it to stdout, so you can redirect it to tar. I'm
not a shell expert so make sure this is correct, but something like
this might work:

su -c backuppc '<path_to_BackupPC>/bin/BackupPC_tarCreate -h <host> -n
<dump_num> -s <share> -p <path> | tar xv -'

where:
  <host> host to dump
  <dump_num> is the backup to dump, use -1 for the latest.
  <share> the share to dump
  <path> The path to prepend to the root of the backup (didn't work
for me but I don't know what it expects)

It worked for me and put the files in the directory I ran the command
from. Tar had an error but I think it was trying to do something to
the special directory "." Also, make sure the user backuppc has write
access to the directory.
