# Script mode, possible values: backup, osupdate, osnotify.
# backup    -   Only backup will be performed. (default value, if none provided)
#
# osupdate  -   Installs new RouterOS if available and creates backups before/after update (ignores `forceBackup`)
#               Sends email only when an update is found.
#               Set `forceBackup` to true to always create backups, even without updates
#
# osnotify  -   Sends email only if a new RouterOS update is found (no backups)
#               Set `forceBackup` to always create backups on every run
