It backs up to local fixed HDD. Then you rsync to the USB drive. You treat the local fixed HDD as your offical Bacula backup and manage it through Bacula. Your USB drives are merely backups of your backups. -- Dan Langille - http://www.langille.org/ BSDCan - The Technical BSD Conference: http://www.bsdcan.org/ ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
