Backup Boards

Hi I noticed a couple of conversations about this but not feature request yet.

This would be very helpful for my team as everyone has full access to edit (and they need to) but mistakes do happen.

It would be nice to manually backup if needed for instance, about to modify the board but need a backup in case something goes wrong.

Also, automatically backing up the boards every day or whatever to ensure we can always reupload the backup into

Airtable has this feature and it works very well.
