The 'archive host' concept exists mostly to provide a web interface to
generating the tar archives.  If you are going to automate it with
cron or use the command line you are probably better off using the
BackupPC_tarCreate command line tool in your own script where you can
use whatever options you want.

I think he said he sent it through gpg encryption, not that backuppc
did it automatically.   But, it is probably easier to use openssl in a
pipeline.  So you could use:
BackupPC_tarCreate  ..options...  |gzip |openssl aes-256-cbc -salt -k
password  >/path/to/file

BackupPC_tarCreate will 'fill' the out with data from the previous
full, so the tar runs will be complete.
