Hello,
Express backup recommends scheduling backups to ensure data security on this page: https://www.nchsoftware.com/accounting/kb/1117.html
Also, this tutorial shows how to set the scheduled backup: https://www.nchsoftware.com/accounting/de/tutorial.html#backup
However, on a Mac this option does not exist in the backup dialog. Is there any other place/menu in the Mac App where I can define a schedule or is there any workaround for this?
