There is an Export option in Data Source Settings, but you have to go in and remember to do it. A client recently lost their Data Source Settings when their Jet Report license accidentally lapsed and it was a royal pain to get them back.
It would be a great feature if you could schedule a Data Source Settings Export on the Jet Scheduler, then you could just schedule it and be done with it.
Assuming a setup dialog similar to other Scheduler dialogs, it would be nice to have have a basic export file name defaulted for your, along with a couple other options like overwrite existing export file, prepend or append current date and/or time and/or datetime to specified export file, prepend or append next numeric sequence to specified export file (e.g. 01DataSourceExport or DataSourceExport02) where Jet would automatically calculate the next number in the series.
