Mike is the most recent person to suggest: (I'm unable to find a task created for this, so must have been discussing in email.)
I have a handful of frequently updated files for which I like to have a versioning backup. In addition to destination, etc, the settings would identify which files are to be selected, the backup frequency, and the number of versions to be kept. The latter two could have a system level default with the ideal option to override at the file level. I could go into a lot more detail but I think this should give you the gist of what I like to see available.
This is also something I want Replicator to do, but it might be a function for the next modern release. Building out much more user interface in Visual Basic 6 Windows Forms sounds like a bad investment of time. Anyway, I want versioned files, too.
