module BackupHelper
##
# The idea here is to only allow users, who can confirm their password, to backup
# OpenProject without delay. Users who can't (since they use Google etc.) have to wait
# just to make sure no one else accessed the computer to trigger a backup.
#
# A better long-term solution might be to introduce a PIN for sensitive operations
# in general. Think the PIN for Windows users or trading passwords in online trade platforms.
#
# Also we make sure that in case there is a password that it wasn't just set by a would-be attacker.
#
# If OpenProject has just been installed we don't check any of this since there's likely nothing
# sensitive to backup yet and it would prevent a new admin from trying this feature.
