Two questions on scheduled backups
 

1. With an established schedule for specific items, can I view the items list to make sure I included (or excluded) everything I intended? CCC, for example, doesn't let me do that.

If I CAN view the scheduled data,

2. Can I change that schedule? Can I go back in to check or uncheck a few items? Or do I just have to create another new schedule altogether?

I searched some key terms in the manual and didn't find anything that seemed to apply. If the manual does explain either or both of these, please just direct me to the corresponding pages.

Thanks.

Do you mean is there a way to do a 'dry run' of your copy? There is not, scheduled or not.

You also cannot 'edit' a schedule, but you can certainly edit a copy script, and if the schedule references that script, it will get the newest version you modified (and that's where files are included/excluded).
