Every system administrator has experienced the panic of a night-time database backup failure. When a production PostgreSQL or MySQL database reaches 50GB or 100GB, running a standard pg_dump > backup.sql command writes the entire database dump into your server's root partition (/tmp or /var/backups). If your disk fills up, the database engine locks up, causing an immediate production outage.
Never write database backups to your local database server disk. Instead, stream the binary standard output of pg_dump or mysqldump through an encrypted compression stream directly into Google Drive's API using rclone rcat or a streaming cURL worker. The dump bytes flow from memory directly into Google's datacenter, completely isolating your database disk from storage exhaustion.
