I recently updated my kobo devices and saw that there’s a Google drive option now for storing books elsewhere, for the time being I’ve just been using calibre and moving files over myself, would there be any concerns to host non drm ebooks from mam on a Google drive if I’m only sharing it with like one person.
Cheers^^
As long as your Drive folder is not made public and gets accessed by many people, you should be fine.
Make sure to make backups outside of Drive though, in case Google decides to delete your files.
