Enable Cloud SQL automated daily backups
SQL instances can optionally be specified, otherwise iterates all running non-replica SQL instances
To take an immediate backup, run the adjacent script:
gcp_sql_backup.sh
Cloud SQL backups are deleted with SQL instances so while these are convenient, you should also do full exports to GCS using the adjacent script:
gcp_sql_export.sh
Backup maintenance windows are 4 hour blocks - set the CLOUD_SQL_BACKUP_START_TIME environment variable in HH:MM format ( UTC) to change it from the default 01:00 am
