* Logs the given line, adding (relative) time stamp and newline |

| 817 |
* - Messages at level 'error' are not logged to file - it is assumed that a separate call to log() at another level will take place. This is because at level 'error', messages are translated; whereas the log file is for developers who may not know the translated language. Messages at level 'error' are for the user. |
| 818 |
* - Messages at level 'error' do not persist through the job (they are only saved with save_backup_to_history(), and never restored from there - so only the final save_backup_to_history() errors |
| 819 |
* persist); we presume that either a) they will be cleared on the next attempt, or b) they will occur again on the final attempt (at which point they will go to the user). But... |
| 820 |
* - messages at level 'warning' persist. These are conditions that are unlikely to be cleared, not-fatal, but the user should be informed about. The $uniq_id field (which should not be numeric) can then be used for warnings that should only be logged once |
| 821 |
* $skip_dblog = true is suitable when there's a risk of excessive logging, and the information is not important for the user to see in the browser on the settings page |
| 822 |
* The uniq_id field is also used with PHP event detection - it is set then to 'php_event' - which is useful for anything hooking the action to detect |
