#!/bin/sh | |
# This script is to be used in combination with Synology Autorun: | |
# - https://github.com/reidemei/synology-autorun | |
# - https://github.com/Jip-Hop/synology-autorun | |
# | |
# You need to change the task_id to match your Hyper Backup task. | |
# Get it with command: more /usr/syno/etc/synobackup.conf | |
# | |
# I like to keep "Beep at start and end" disabled in Autorun, because I don't | |
# want the NAS to beep after completing (could be in the middle of the night) | |
# But beep at start is a nice way to confirm the script has started, | |
# so that's why this script starts with a beep. | |
# | |
# After the backup completes, the integrity check will start. | |
# Unfortunately in DSM you can't choose to receive email notifications of the integrity check results. | |
# So there's a little workaround, at the end of this script, to send an (email) notification. | |
# The results of the integrity check are taken from the synobackup.log file. | |
# | |
# In DSM -> Control Panel -> Notification I enabled email notifications, | |
# I changed its Subject to %TITLE% and the content to: | |
# Dear user, | |
# | |
# Integrity check for %TASK_NAME% is done. | |
# | |
# %OUTPUT% | |
# | |
# This way I receive email notifications with the results of the Integrity Check. | |
