I've recently switched from Strongspace to rsync.net and now use Duplicity to do the backups. This uses GPG to encrypt the backups and handles incremental backups. Duplicity is is portage with a good man page, there is also documentation on using it with rsync.net on their support pages as it is their recommended solution for encrypted backups. -- Neil Bothwick BASIC: Bill's Attempt to Seize Industry Control
