How do I use the history

In History window you can see all logs for the backup, restore, test and clean actions.
The logs can be filtered by job group name, action type, status (success, warning or error) and date.
Double click or right-click on a log to open it. You can read more about this functionality in the following article : http://www.backup4all.com/kb/how-do-i-use-the-history-896.html
