btw, you can also use pgbackrest for backups. i'll let docs do the talking, pgBackRest - Reliable PostgreSQL Backup & Restore <https://pgbackrest.org/> but it can help you manage incremental and differential and full backups along with parallel support. (so fast and less bandwidth) also a quick online tutorial to help you get started.
