Keyring_component plugin and pxb

MySQL & MariaDB Percona XtraBackup

Hi,

What is the process of backup and restore if the mysql is using keyring component?

Based on this, is my understanding correct that for performing backup, we don’t need to specify the keyring component path but to prepare the backup?

Do we need to have a copy of keyring component file which is pointed by the path specified in component_keyring_file.cnf file, e.g.? everytime we perform backup with pxb?

component_keyring_file.cnf: 
    {
      "path": "/bitnami/mysql/data/component_keyring_file",
      "read_only": false
    }

Hello Charly,
Yes, that’s correct. To take a backup, you don’t need to provide the keyring path. However, to prepare a backup, you need to have access to the keyring file on the instance from which you took the backup.
