I think FBackup is great! A few suggestions for improvement of the free version, if I may:
- it would be very good to be able to add multiple folders at once, rather than having to use the Add Folder button for every single folder. I know that drag&drop is only supported in the paid version, but what I'm suggesting is a simple checkbox next to each file/folder, which can be ticked if the user wants that file/folder as part of the source
- if a file is deleted in the source, the corresponding file in the destination can also be deleted during a backup, or can be kept for a number of days after the source has been deleted. This should really be a setting under Preferences...
- being able to set the main program thread priority
- display Estimated Time Left
