New or increase date create version backup criteria

I saw that sometimes new backup had to create (due AddedFiles > 0 or AddedFolder > 0 and so on) but it’s not created but date of last version date-time is incremented. Why and how I know: backup wasn’t created, created with current date or only date-time of last version is incremented?

May be better to created a new param result for this?

So you’re saying that your result report shows 1 or more AddedFiles or AddedFolders but the LastBackupDate in the result does show the same date as what was just backed up?

Thank you. I didn’t know before that there is backend statistics.

I think the reason in retention policy: one backup per day. So this is why the time of last backup is increasing if I manually start backup few times per day.

I’d have to double check but I think LastBackupDate is the previous run time (not sure if it has to be successful or not) whether it’s scheduled or manual.

I don’t see BackendStatistics in results. Ver. Upgrading to May be in last version if will find it.
