Description:
MySQL server has component_keyring_aws installed and working.
When running mysqlbackup it fails with error:
[ERROR] [MY-010900] [Server] Can't find symbol '_mysql_plugin_interface_version_' in library.
It seems its trying to load plugin, but I am using component, not plugin.
How to repeat:
1. Have MySQL 9.7 up and running with component_keyring_aws installed.
2. Run backup command:
mysqlbackup
--backup-dir D:\MySQL_Backups
--host=127.0.0.1
--user=mysqlbackup
--password=xxx
--encrypt-password=xxx
--backup-image=D:\MySQL_Backups\backup.mbi
backup-to-image
3. Observe log:
