Suppose you run a database as a service (DBaaS) for example in Azure. You have automated backups configured in case something bad happens. However these backups do not save you against a accidental database deletion as the backups get deleted, too!
Then there’s the Open Telekom Cloud (OTC). The DBaaS there have the same problem. If you delete a database there, the backups get deleted, too. However only the automatically created ones get deleted, not the manually created ones. You can use this feature to save yourself (partially) from accidental deletion of databases. Just create some script or automation that peridocally creates (and deletes) “manual” backups!
