Point-in-time recovery helps you recover an instance to a specific point in time. For example, if an error causes a loss of data, you can recover a database to its state before the error occurred.
A point-in-time recovery always creates a new instance; you cannot perform a point-in-time recovery to an existing instance. The new instance inherits the settings of the source instance, similar to how clone creation works.
Point-in-time recovery is enabled by default when you create a new Cloud SQL instance.

General tips about performing a restore
When you restore an instance from a backup, whether to the same instance or to a different instance, keep in mind the following items:
- The restore operation overwrites all data on the target instance.
- The target instance is unavailable for connections during the restore operation; existing connections are lost.
- If you are restoring to an instance with read replicas, you must delete all replicas and recreate them after the restore operation completes.
- The restore operation restarts the instance.

Tips and requirements for restoring to a different instance
When you are restoring a backup to a different instance, keep in mind the following restrictions and best practices:
The target instance must have the same database version and edition as the instance from which the backup was taken.
The storage capacity of the target instance must be at least as large as the capacity of the instance being backed up. The amount of storage being used does not matter. You can see the storage capacity of the instance in the console Cloud SQL instances page
The target instance must be in the
The target instance can have a different number of cores or amount of memory than the instance from which the backup was taken.
