rsync like backup to Rackspace Cloud File with duplicity

It seems that there is no much documentation about how to do rsync like backup with duplicty so here it is :

UPLOAD_TO_CONTAINER="backup" #adjust it as you like
export CLOUDFILES_USERNAME=Your Username
export PASSPHRASE=The Passphrase for your encrypted backup

duplicity /full/path cf+http://${UPLOAD_TO_CONTAINER}

This should take care to upload the backup files to the backup container. It does that incrementally and detect the changes to your file system to upload. There is much more option for duplicity look at the manpage for more info.
