############################### Backup Script ################################# | |
# Backup script invoked by systemd (timer) to ensure hourly backups. # | |
# DATE is not appended to the file. This is because the server used as TRG # | |
# snapshots the data set and saves: hourly snapshots for a day # | |
# daily snapshots for a weekly # | |
# monthly snapshots for a year # | |
# # | |
# At the moment the script starts of by checking that the laptop is charging; # # | |
# The script also checks that the computer have internet access. If both are # | |
# satisfied, we sync away. # | |
