Have an option for automatic periodic exports/backups

For backups, we can

• Take a backup of all the data files
• Take a backup of the Postgres
• Use the "export" option within Outline itself


Personally, I find the export option most convenient as it retains all the data needed and can be easily exported


It would be great if there was a feature to automatically export data at a periodic cron time. Ideally to a S3 would be even better
