Overview
Connection guides for managed database platforms — which connection string to use, network access rules, and how restore tests handle each platform's managed extensions.
Most databases connect to Backup with a standard connection string — see Connect a database. These guides cover managed platforms that need something specific: a particular connection string, network access rules, or handling for platform-managed extensions during restore tests.
Whatever the platform, the two things to get right are: give Backup a connection
its dump tool can use (the direct database, not a transaction pooler), and allow
Backup's egress IP 18.196.207.101 if the platform restricts inbound
connections.
PostgreSQL
Supabase
Use the session pooler, not the direct connection, and what restore tests do with Supabase's managed extensions.
Amazon RDS & Aurora
Public access, the security-group rule, and the aws_* extensions restore tests recognise.
Google Cloud SQL
Public IP, authorized networks, the right SSL mode, and google_* extensions.
Azure Database for PostgreSQL
Flexible Server: the firewall rule and Azure's managed extensions.
Neon
The direct (unpooled) connection, auto-suspend, and Neon's platform extensions.
Aiven for PostgreSQL
The service URI, IP filter, and the aiven_extras extension.
DigitalOcean
The direct database on port 25060 and the Trusted Sources firewall.
Render Postgres
The external connection string and IP allow list.
Heroku Postgres
Rotating credentials, and using a stable dedicated credential.
MongoDB
Running on a platform not listed here? It almost certainly connects with its
standard connection string — follow
Connect a database, and make sure the
database allows Backup's egress IP 18.196.207.101 if it restricts inbound
connections.
Test the connection
The auth-aware connection probe — what it checks, every result code, and the common fixes.
Supabase
Back up a Supabase database — send independent, restore-tested backups of your Supabase Postgres to storage you control. Which connection string to use, network access, and what restore tests do with Supabase's managed extensions.
