Encrypted Backups for Percona Operator for MySQL based on Percona XtraDB Cluster

Hi there,

I am currently using a MySQL 8.0 XtraDB Cluster hosted on Kubernetes and deployed with the Helm chart found here.
So far I have configured the chart so backups are automatically created to an S3 storage. Unfortunately they don’t seem to be encrypted and I cannot find an option to turn encryption on. The documentation found here provides no information on how to encrypt the automatic or manual backups although the documentation here states that it should be possible using a simple command line argument.

Am I missing something? Help is greatly appreciated.

Best Regards,
