Seriously, I don't understand why it isn't possible to do this or even to manually backup PDFs. I don't want all my data in the cloud, but I do want access to my notes.

same, it would my life and my employees via Gsuite's life so much more easy if it did an automatic backup to google drive

I came here looking for this exact thing. This seems like it'd be easy to implement, and would allow users to backup to google drive (if they have it on their device) in one sweep.

I am a premium member. Why does cloud backup have an option for automatic schedule but local backups do not? Can we get scheduled local backups for those who are premium member members?

I use cloud backup, which is okay (I have a Dropbox account that I use only for Squid), but I'd much rather backup automatically to the local drive and use other software to transfer those local backups to Google Drive.

I would be also good to have local backup saved with prefix timestamp in the filename.

When many files are generated the old backups should be pruned using some sort of rules. For example, by keeping at most d daily backups, w weakly, m montly backups, y yearly.
