I know I am late to the party here but I wanted to put in my suggestions.

Regarding actual backup reports, it would be nice to have the option to get a txt file of all files backed up, skipped/failed and any deleted as part of the retention settings in the notification email after a backup completes.

If anything, I would love to get a report of which files were skipped/failed in the backup status email after a schedule completes. Thanks!
