Cloning instances

This page describes how to clone a Cloud SQL instance.

When you clone a Cloud SQL instance, you create a new instance that is a copy of the source instance, but completely independent. After the cloning operation is complete, changes to the source instance are not reflected in the clone, and vice versa.

The source instance configuration (activation policy, database flags, connectivity, and so on) is copied to the clone. Instance IP addresses and replicas are not copied; you must configure these items explicitly on the clone. Cloning an instance does not clone any existing backups.

You cannot clone a replica. You can clone an instance that was cloned from another instance.
