thanks for Deja-dup application. It’s simple and intuitive but I think it miss a feature: multiple destination backup. I know Deja-dup is targeted to casual Linux user but it would be safer to store backups to multiple locations (for example to external HDD and Google Drive at the same time or whole backup to external HDD and only some directories to Google Drive). Even world famous Apple Time Machine can backup to multiple disks.
I also know there are alternatives to Deja-dup, but none of these is intuitive as this Gnome app.
So, please consider to add this feature in the roadmap.
