#
# Copies all sources to target host 
# ================================= 
#
# Copies all folders in ./sources to the target.
# These folder entries (seperated by newlines)
# should not end with a slash. If they do, only the
# files inside the folder are backed up, not the
# folder itself. Make sure that there are no
# trailing spaces after the entries.
#
# The ssh key used to ssh into the target should be
# located in ./ssh/id_rsa, or changed below.
#
# Additionally, you need to make sure that ./logs/
# exists. Rsync stdout will be logged to that folder.
