I know this is an old thread But just found it.
Know you need maybe 3 backups of most important things
But my question is, how do you back up when you have added new books to your main EBooks folder without deleting the back up (on external pen drive whatever) before copying across the updated EBooks folder
As just to pen drive it takes forever
Is there a way to just add the new books (in calibre folder) to the backup?
