Backup only when System on

Hello,

how i can configured the Client then he make a Backup only when he was started.

For example i have many Clients that’s was not every Day used. Actually i become a false positive notification that no Backup are created on the last x hours/days and not actually Backup Status on the Webinterface. Correct no online Client no “actually” Backup.

Many Thanks!

Many Greetings
