# This script notifies you when restic runs successfully or unsucessfully via  #
# Pushover.                                                                    #

# TO RUN:                                                                      #
# - Download and change the settings to the right values.                      #
# - You will need a Pushover user key and application key.                     #
# - You will need to have the restic repository password set in an enviromental#
#   variable. You can do so in this file via RESTIC_PASSWORD or                #
#   RESTIC_PASSWORD_FILE.                                                      #
