Enable Cloud SQL point-in-time recovery
|
|
|
|
SQL instances can optionally be specified, otherwise iterates all running non-replica SQL instances
|
|
|
|
This automatically creates a backup at the time of enabling, which takes a few minutes during which your database may be unavailable.
|
|
|
|
WARNING: Enabling/Disabling point-in-time recovery restarts the instance, causing an outage, so this script will prompt for confirmation before proceeding.
|
|
|
|
Requires automated backups to already be enabled, otherwise you'll get this error:
|
|
|
|
ERROR: (gcloud.sql.instances.patch) HTTPError 400: Invalid request: Point in time recovery must be disabled when backup is disabled.
|
|
|
|
See adjacent script to enable automated backups first:
