using duplicity with hubic to backup home directory on ubuntu linux

gistfile1.sh

# preparations
# ------------
# create a new application in hubic account manager 
# visit https://hubic.com/home/browser/account/
# Developers > Add an application
#  Name: backup
#  Redirection domain: http://localhost/
# copy "Client ID" and "Secret Client", it will be used later

sudo apt-get install librsync-dev libffi-dev python-virtualenv python-swiftclient

# install duplicity
# -----------------
# to avoid having to mess with dependencies, package versions etc, 
# just install the latest version of duplicity locally in
# $HOME/.backup
# this version supports hubic, using the pyrax library

cd $BAKDIR

# to make a backup (this can be added to crontab)

# to check the status of the remote repository

# since files won't show up in the hubic browser we use this script
# which provides ls-like functionality

pip install -r hubic-wrapper-to-swift/requirements.txt

# this script uses very similar config format as pyrax above,
# the only difference is the use of email vs username
# just provide both keys in the config file
ln -s ~/.hubic_credentials ~/.hubic.cfg

# create a new container
./hubic.py --swift -- post bak-hostname

# list all containers
./hubic.py --swift -- list --long

# list contents of a container
