Second, once a ticket has been deleted, is there any way to recover information about such ticket? I mean, is there a record of deleted tickets and at least the initial article that generated the ticket itself or does the ticket removal purge any piece of information? This is not a silly question, since sometimes we are asked to delete tickets just to discover, minutes later, that it had to be kept. Therefore, is there any other way to mark the ticket as “invisible” if deletion effectively destroy everything?
I’ve found that there is “data privacy” task, that if selected as action for the schedule reports the warning “All affected tickets will be scheduled for deletion when this job is run. Once the data privacy task is executed, tickets will be deleted and a history entry preserved. There is no rollback of this deletion possible.”
Therefore some sort of historical record is kept, it seems…
There is no record kept. The only thing Zammad “remembers” for… I believe half a year is the ticket numbers that where removed. Nothing else. So it doesn’t exactly help you.
