In Backup4all you can use the default job icon, you can select another icon from our list of icons or you can use your own icons. Here is the backup job default icon when no action is performed for that job .
If one or more files could not be backed up (not enough user rights etc.), then the Warning icon representing the exclamation mark on a yellow triangle will appear in front of the default backup job icon, after the backup finished. Read the log files (from Jobs->View log->Last Backup log) for details about the files that were not backed up. The Warning icon will disappear when the backup is executed again and all files were backed up.
If an error occurred during backup and the backup was aborted, the Error icon representing a red circle with an white X, will appear in front of the backup job. Read the log files (from Job->View log->Last Backup log) for details about the errors. The icon will disappear when the backup is executed again and the execution is successful.
