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
