Is the Whatsapp backup Feature activated by default? If you use Whatsapp on your android phone, are the chat backup features activated by default?

If so, how is the backup intervall by default? daily, weekly or monthly? Are the chat backups being stored on the phone or on google drive?
By default WhatsApp would make a local backup daily (Stored in the phone), but if you wish there is an option to also backup to Google Drive after the local backup finishes, i am not sure if the Google drive backup is set to ON by default but the option is there.
