Just a quick one here. Please is it possible to delete history entry (audit trail) apart from purging it by not adding it to backup?
No there isn’t.
Ability to delete history would be trivial to implement however the guiding principle here is that you should be able to “undo” anything that you do in Manager.
But deleting history cannot be undone. So this is not implemented on purpose.
The only way to delete history is to make a copy (backup) of existing database that will exclude history.
