Yes, the engine has crashed. My guess is that there is some task that contains some complex event (post or pre backup) that is not in the same format that it's used in the new version. Would be interesting to take a look at your old list.

Yes sorry, it should be 1. And add thevalue to the registry.

And this is a general setting for any program using WPF.

Thank you for sharing!

Is your task incremental or differential?

Add a filter of type Date older than... for the task.

Try setting

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics\DisableHWAcceleration

to 0

(Untested)

Just use a parameter instead of the default subject. See the help file under Parameters.

The only solution I see if to use the much maligned Mirror function.

It should be possible if ALL files in the folder are older but not if only some of them.

Do you mean, if the source structure is changed, scan then the destination for existing files? Is it not easier to delete the existing backup and force a new full backup plus normal incrementals then?
