The Mac version has gotten a lot of good response, so I tried installing the Windows version. It feels a bit like a beta sadly.

  - Backups to local folder do not work
  - Scheduled backups don't always run until you open the GUI
  - Open log viewer before any backups have been performed crashes the app
  - File-Exit does nothing
  - Wizard adds whole C:\ to first destination
  - Doesn't seem to backup (all) locked files

I've reported all of these, and the author seems responsive, so I hope it gets better.
