Encryption for XtraBackup + xcloudBinary to S3

MySQL & MariaDB Percona XtraBackup
1

I’m thinking of using XtraBackup and XCloudBinary to transfer MySQL backups to S3.
At that time, I would like to encrypt the communication path, but is encryption enabled by default?

Regarding encryption of the data itself, it was stated that “–encrypt-chunk-size” must be set to the same value as “–read-buffer-size”.

However, I think communication with S3 is HTTPS by default, so even if I don’t specify any options, is there any problem in assuming that the communication route is encrypted?

Communication between your server (xbcloud) and AWS S3 is SSL, thus your data is encrypted during transit to S3.
